1 Introduction

An access control system provides a means to replace traditional key and lock systems, whichare easy to defeat because of the ease of copying of keys and use by unauthorized personnel.With electronic access control, the exact areas a person is able to access as well as during whattime is configurable through a central control system. In addition to the power of greater control, ahistorical record is maintained which is useful in the case of a system security breach or for otherpurposes including calculating work time and facility use costing.

1.1 Overview

The APN-35 is a standalone two door controller used for connection of two Wiegand type cardreaders and all the necessary input and outputs associated with two access controlled doors. TheAPN-35 can also be used for a single door operation with entry/exit readers and anti passback. Ifthe APN-35 becomes disconnected from the host software package the APN-35 continues tooperate all functions of the system without reverting to a degraded mode. The APN-35 supportsstandard proximity and other readers with Wiegand interfaces such as bar code, smart card,biometric, keypad, etc. The APN-35 also supports Magnetic stripe readers utilizing ABA Track 2encoding. The APN-35 provides complete time zone control of access with its battery-backed realtime clock. Up to 1000 events are internally buffered for transmission to PC when communicationsis restored.

1.3 Modes Of Operation

To establish operating configuration, the APN-35 interface requires connection to host PCequipped with software compatiable with the APN-35. Apollo provides the ASW-35 software freeof charge for this purpose. Software configuration options including cardholders are stored in acentral database and then transmitted APN-35 controller. Once programmed, the software willcommunicate with the APN-35 interface to upload configuration the following configurationinformation:· Card Reader Data Output Format: Wiegand or Mag Stripe· Strike Time—The time duration that the strike relay will be energized for in the case of an

access grant· Held Open Time—After an access grant and a subsequent opening of the door contact, the

time in which the door contact must be closed before an alarm state is reported· Initial Reader Mode—The access mode in which the reader will function. The following modes

are supported:

o Card Only—An access request is made by presenting a card to the reader. The data is verified against the APN-35 database to ensure that the card has a valid Facility Code andCard Number.

o Card or PIN—Access requests are made either by presenting a card or by keying in a PIN(Personal Identification Number) on a keypad. A card entry is process as in Card Onlyaccess mode.

o Card & PIN—A card must be read to start the access request. If the card is valid, the user isprompted to enter the corresponding PIN. The request is granted only if the card and PINmatch.

o Locked—No access granted. Reader ignores all cards and PIN entries.o Unlocked—Door strike is continuously energized and the door contact input is not monitored.

Access is not controlled.o Facility Code—The entire card contents are read by the APN-35, but only the Facility Code is

checked, and if it matches a Facility Code downloaded from the software, access is granted.

2.3 Connectors

The APN-35 has several connectors for interfacing with removable components. Take care wheninstalling and removing components in order not to damage pins or sockets. Do not use forcegreater than gentle pressure when installing any components. Refer to the figure for theexact location of these connectors.

2.3.1 Device Port Communication Driver Socket

Port Communication Driver Socket:

For the functioning of serial communication on the APN-35, a proper communication driver mustbe connected to the 12-pin socket. The communication driver module can be either ASD-48(RS-485, part number 482-485) or ASD-23 (RS-232, part number 482-485) depending on the typeof communication required to the PC. The module should be installed so the pins of the ASDalign with the driver socket and then gentle downward force should be applied to the top andsides of the ASD until the pins slide completely in the socket.

2.3.2 Additional Connectors

Additional Connectors/Jumpers: J2

This connectors is used for factory configuration and should not be modified or connected in anyway unless directed by your technical support.

2.3.3 LEDs

The APN-35 has 2 LEDs for use in monitoring functioning of panel and for diagnosis of problems. The LEDs function in two modes: startup and normal operation

2.3.3.1 Start Up Mode

Immediately after powering on the panel, the start-up test will initiate and the results will be displayed on the LEDs. If there are no failures, the test will progress If the panel encounters anerror, it will stop with the failed test and display the LED sequence corresponding to that test. Thetest sequence and the LED codes are:

Test D9 D8

ROM/Firmare ON OFF

RAM OFF ON

Test OK—Loading Config ON ON

Table 2. 3: APN-35 Start up LED Function



2.3.3.2 Normal Operation

After initialization and self tests, the LEDs will switch to normal operation and will displayinformation about the panel operation.

Heartbeat (D9)—Shows a constant ‘heartbeat’ (0.2 sec ON, 0.8 sec OFF) to indicate properoperation of the panel and firmware.

Port Status (D8)—Shows activity on the serial port. Normal activity on the ports will be observedas the LED blinks many times a second or lighted solid, depending on the amount of activity.

2.4 Firmware

The operating program for the APN-35 is stored in re-programmable flash memory. In the eventthat the firmware must be re-installed or updated, no chips need to be replaced on the panel. Thenew program can be loaded from the host via special software. For normal operation it is notnecessary to update the firmware. If this becomes necessary, contact your Apollo supportrepresentative. Firmware updating should only be done under the recommendation and guidanceof your Apollo technical support representative.

2.5 Memory Backup

The APN-35 is equipped with on-board memory to store configuration information and event data.This memory, as well as the real-time clock, is provided with back-up power (for up to 5 days) inthe event of primary power failure. Power is supplied by an onboard rechargeable battery. Battery replacement is never required.

2.6 Additional Installation Information

2.6.1 Mounting Holes

Four holes are provided for mounting the APN-35 at each of it's corners. Take care not todamage the circuit board by applying too much pressure when tightening screws. The use ofplastic screws and washers is recommended.

SPECIAL NOTE: To guard personal safety and avoid damagingequipment it is important to have a full understanding ofelectrical wiring practices and safety. The following sectionsprovide general guidelines relating to the APN-35, but are not asubstitute for complete training in dealing with electricalsystems!

3.1 Power

Power Connection: TB1

Power is supplied to the APN-35 by the voltage connection in terminal block 1 (see Part 2.1 forexact locations of terminals). The power connection should be 8-28 VDC. Power consumption is150 mA. The APN-35 is protected from over-current and over-voltage by on-board circuitry.

Take care when selecting a power supply for use with the APN-35. Most power supplies in themarket today provide good input/output isolation, however those which do not provide isolation (orhave high leakage capacitance), coupled with accidental AC power lines interchange, presentserious ground fault problems for installers. With ground fault, the signal reference betweensubsystems may be 115 VAc (230 VAc) apart. If these subsystems are interconnected, the largepotential difference will cause equipment damage or personal injury. Apollo recommends the useof isolated continuous power supplies only. All Apollo supplied power supply assemblies aretransformer isolated for safety and to minimize ground loop problems.

In the case of over-current, solid-state fuses integrated on the APN-35 panel will ‘trip’ to protectthe components of the panel. In many cases, the solid-state fuses will reset automatically whennormal current resumes, however it may be necessary to interrupt the supply of power to allowthe fuses to reset.

3.2 Grounding

Special care should be taken when grounding the APN-35 controller and other devices connectedto it via the direct communication lines. Each device must be grounded to provide ESDprotection, personnel safety, and signal reference for devices which communicate with eachother. Grounding the reader provides a good shield against external transients. There are threetypes of circuit grounds in systems using Apollo products: DC ground, RS-485 signal ground, andSafety (Earth) ground.

3.2.1 DC Ground

This is typically the minus (-) side of the DC output of the power supply. It is to be connected tothe DC ground input of all devices being powered by one supply. It must not be connected in anyway to any of the 5 RS-485 signals or the AC side of the line including Safety (Earth) ground (oneconnection to Safety (Earth) ground is acceptable, but this connection is usually internal in thehost computer and should not be introduced externally if direct connection is used (RS-232/485)).

14System Wiring


3.2.2 RS-485 Signal Ground (SG)

This is the 5th wire used for the RS-485 communications. It is used to provide a commonreference between all devices on the line and should only be connected to each of the devices' SG input. The SG wire must not be allowed to touch any other potential, especially earth ground. The shield drain wire of the RS-485 communications cable is commonly used to connect the SGleads together. Usually this wire does not have an electrical insulator. It is important that the SGwire is thoroughly insulated by the installer at all connection points. Improper insulation of thisconductor may allow accidental shorting to earth ground through conduit or other metalliccomponents, causing intermittent communications or equipment damage.

3.2.3 Saftey (Earth) Ground

Safety ground is part of the AC power system. To avoid ground loop current, there must be onlyONE point at which the safety ground connects to the DC ground.

The RS-485 signal ground must be isolated from the safety ground. This means that the RS-485cable shield drain wire must be insulated at connection points so that it will NOT accidentally shortcircuit to the conduit in instances where the conduit is connected to the safety ground. (See Figure117)

Please check the applicable regulations and legislation in your country prior to installing theAPN-35 controller and other Apollo products. In the US, the National Electrical Code, as well asother safety regulations, require that all equipment chassis and/or enclosures be grounded inorder to prevent electrical shock hazards. Each device must have a green wire safety ground. Thefunction of the green wire safety ground is to provide a redundant path for fault currents and toinsure that the circuit breaker will open in the event of a fault. In addition, grounding the enclosureprovides a path for ESD dissipation, thus protecting sensitive electronic devices. (See Figures 115and 116)

3.2.4 Grounding System

A grounding system can be viewed as two subsystems: the DC system and the Ground System.The DC system consists of all interconnected power supply returns, DC distribution wiring, andload devices. The principal function of the DC system is to provide signal reference forcommunication. The Ground System consists of all chassis grounds for power supplies and otherdevices, safety grounds, and AC grounds. Ground connection should be made to avoid groundloop problems. (See Figure 115)

Ideally, there should be ONLY ONE ground return point in a power supply system. In a systemwith a PC (personal computer), it is likely that the PC already provides the DC Ground connectionto the Ground System (earth ground). Care must be taken NOT to create more groundconnections. In systems with multiple PCs communicating to Apollo Hardware via directconnection, the ground potential must be the same for inter-connection, or some form of isolationmust be provided.

3.2.5 Grounding Potential Difference Checks Before Connecting

Before a device is connected to an RS-485 subsystem, it must be checked for ground fault.Uncorrected ground fault can damage all devices connected to the RS-485 communication line.

To check if there is ground fault for a new unit, follow the steps below (See Figures 105, 113, 115,116 and 120):

1. Apply power to all devices already successfully connected to the RS-485 line.



2. Power up the new unit, but DO NOT connect it to the RS-485 line.

3. Connect the signal ground (SG) of the RS-485 line through a 10k limiting resistor.

4. Measure the AC and DC voltage across the resistor. There should NOT be more than 1 volt across the resistor. Otherwise find and clear the fault.

5. Connect the new unit to the RS-485 line only if no ground fault is found.

3.3 Communication Connection

The serial connection from the APN-35 to the host PC is used to transmit configuration, collectrequests and information from the APN-35 to the controller and for the controller to transmitresponses to these messages. The APN-35 does not originate communication on the devicecommunication line but waits for a poll from the PC and then establishes communication forconfiguration. The first communication from the PC establishes the presence and properfunctioning of the field device, and then the configuration is subsequently sent in the followingpolling cycles. This polling is done many times a second, with the exact parameters for polling(intervals, timeout, retries) being set by the host software.

The connection to the host may be made by RS-232 or RS-485 serial communication. The choiceto use RS-232 or RS-485 depends on many factors for the particular installation. The maindifferences are outlined below:

RS-232 RS-485

Maximum Distance 50 Feet (15 Meters) 4000 Feet (1200 Meters)

APN-35 Per Line 1 4 (Maximum Number ofunique addresses for APN-35)

Communications Port Standard on Many PCs Requires Adapter (RS-232 toRS-485) or Add-on PC Card

Data Rate 20K Bps 10M Bps

Table 3.3.1 : RS-485 and RS-232 Features.

After choosing the method of communication, the proper wiring must be made from the host to thecontroller. Typically, the communication will be from a standard 16550 UART COM-port on a PCwhich will be connected directly to the APN-35 in the case of RS-232 or through the use of anadapter or add-on PC card to achieve the RS-485 signal. The communications wiring mustcross-over from the PC to the panel as shown in diagrams below.

16System Wiring


RS-232

For RS-232 communication, the APN-35 must first be equipped with an ASD-23 communicationsdriver (see Part 2.3). RS-232 communications only allows for one device to be connected to eachPC serial port, so the proper wiring should be made from the PC directly to the APN-35. Apre-manufactured cable can be used, or a special cable can be constructed. The proper wiring ofthe RS-232 cable is shown below:

9-Pin COM Port Connector(front view)

Figure 3.3.2 RS-232 Host to APN-35 Serial Wiring Pinouts. The wiring from thehost to the APN must be done according proper Pin outs and cross-over wiring utilized.



RS-485

For RS-232 communication, the APN-35 must first be equipped with an ASD-48 communicationsdriver (see Part 2.3). An RS-232 to RS-485 coverter or RS-485 add-on board will be necessary tosend the RS-485 signal from the PC. Up to 4 APN-35 units can be connected to one PC serialport. The wiring should cross over from the host and then be in series between each APN. Typically, wiring for the APN-35s will not require RS-485 termination because of the closeproximity. If you are using longer RS-485 lines with the APN, termination may be required. Formore information see Apollo General Installation Guidelines manual or contact your technicalsupport representative.

18System Wiring


3.4 Card Reader Wiring

Up to two card readers can be connected to the APN-35. Card readers with standard Wiegandoutput are supported, including magnetic stripe, proximity, bar code, smart card, biometric,keypad, etc. It is not necessary for the readers to be identical on each connection port, i.e. twodifferent reader types can be used simultaneously.

Each reader connection consists of connection terminals for VDC Output and Ground, Data 1Signal, Data 0 Signal, Beeper control, and multiple LED control (red and green). The wiring to thereader should be made using 24 AWG shielded cable with 4 twisted pairs (Belden 9504 or equivalent). Do not exceed 500 feet (152 m) between the APN-35 and reader. Connect theshield drain wire of the cable at the GND terminal of the appropriate reader connector on theAPN-35. Carefully insulate the drain wire with sleeving for a reliable installation.

Power for the reader connection (VDC) is derived from the power input (VIN) for the APN-35 andis distributed between the two reader connections. Thus, voltage to the reader power connectionwill roughly equal the the voltage supplied to the APN-35 power input. There must be sufficientpower to supply the load of all readers as well as for the APN-35 itself (+8 to +28VDC @ 150mA). If the readers have a greater total power requirement, or if there are other wiring concerns,external power supplies should be used to power the readers. In this case, only connect thereader power lines to the external power supply; do not connect the reader to two power supplies.

For basic operation of the reader, at a minimum the Data 0 and Data 1 wires must be connectedfrom the reader to the APN-35 and power supplied to the reader. LED and beeper control lines donot have to be connected, but in this case, the LEDs and beeper may not function on the reader.

The each of the reader inputs on the APN-35 have three input circuits (Door Contact, Exit PushButton and Auxiliary Alarm 1). These inputs provide information about the status of the doorscontrolled by the APN-35.

If one or all of the normally closed inputs are not used, they should be ‘jumpered’ using a 1” (25mm) long piece of wire connecting the two terminals to form a closed circuit. This will prevent analarm condition being reported to the host.a 'jumper' wire should be installed to prevent an alarmcondition.

Wiring Note: When wiring the inputs of the APN-35, for each door there is one connection for thepositive wire of the in put, but only one COMMON negative (or return) connection for all of theinputs CONNECTED TO THAT READER/DOOR. Thus, if all the inputs are connected forreader/door 1, there will be one wire connected to each of the terminals for Door Contact, EPBand AUX, and 3 wires (one from each input device) connected to COM return connection. SeeFigure 3.5 for a wiring example.

3.5.1 Door Contact Input (Door Position Switch)

This is a normally closed input and should have a jumper installed if not used!

Terminal connectors: DOOR, COM (See Table 2.1 )

The door contact input is a normally closed input used to monitor the open/closed status of thedoor. This will typically be connected to a magnetic sensor in the frame of the door that willprovide a short circuit when the door is closed and an open circuit when the door is opened.

The reader will use this input to detect when the door is opened and when the door is closed. Thisinformation is processed by the reader and used to generate certain alarm messages. If a door isdetected to be opened for no apparent reason (not as a result of a valid card or PIN use or exitbutton activation), the reader will generate a “Forced Open” message. If the door is opened as aresult of a valid access request or exit button activation but not allowed to close within theprogrammed held open time, a “Held Open” alarm will be generated.

The reader may also be configured by the DIP switch to allow early strike relay shutoff. Normallythe amount of time that the reader will keep the strike relay activated is controlled by the “StrikeTime” setting in the host computer. This is the amount of time a person has to open the door afterbeing granted access. This time is adjustable from 0 to 255 seconds (0 = ½ second). If the striketime is configured for 10 seconds (for example) and the person has already opened and closedthe door after 5 seconds, the reader may be configured to terminate the normal 10 second striketime early (thus not allowing the door to be opened twice). If the reader is configured for this earlystrike shutoff option, it is important that the door contact input is working properly. If the input isnot connected or is malfunctioning and the reader detects that the door is always open, erroneousalarms will be generated and the Strike Time will always be very short (the reader thinks thepeople are opening the door quickly), resulting in it being impossible to open the door.

3.5.2 Exit Pushbutton Input (Request To Exit, REX)

The Exit Pushbutton input will be disabled during Reader Tamper and for 1 minute aftertamper condition ends!

Terminal Connectors: EPB, COM (See Table 2.1 )

The Exit Pushbutton input is used by the reader to inform the reader of a door opening withoutfirst using the card / PIN. Normally, if the reader detects a door open condition without valid use of



card or PIN, it will generate a “Forced Open” alarm. This alarm must be masked (inhibited) whenpeople use the door to exit from the inside of any secured area. The Exit Pushbutton input is usedfor this purpose. After detecting a closed circuit of the Exit Pushbutton input, the reader will ignorethe door contact input for a period of time equal to the strike time set for the reader. This allowsthe people to then open the door for exit without an alarm being generated.

Most local fire codes require that exit must be obtainable from all doors regardless of properoperation of the access control system and without any prior knowledge of the system operation.This normally means that some form of emergency crash bar or manual door release be provided.IT IS THE RESPONSIBILITY OF THE INSTALLER TO INSURE ALL LOCAL CODES AREFOLLOWED DURING INSTALLATION.

3.5.3 Auxiliary Alarm Inputs


Terminal Connectors: AUX, COM (See Table 2.1 )

Each reader input on the COM includes one Auxiliary Alarm circuit. These inputs may be used for many purposes that can be configured in the host software. The capabilities will depend on theparticular software system in use. Normally these inputs will be used for monitoring external alarmpoints such as motion detectors or glass break detectors.

3.6 Output Relay Wiring

The APN-35 has two output relays onboard, which are dedicated strike relays for each of the twopossible doors. In addition there are two Auxiliary Outputs, one each readers. These AuxiliaryOutputs require the use of AKM-10 external relay units (part number 400-410). See the followingsections for more information on the AKM-10.

3.6.1 Strike Wiring, General

Typically, doors are held closed and released by one of two methods. An electric door strike isinstalled in the door frame, replacing the mechanical strike plate. This type of strike has a “gate”that is normally held closed and is released by command from the reader. This allows the door tobe opened. A second type of lock is a electro-magnetic lock which is a two piece device mountedon the perimeter of the door. A solid plate is mounted to the door and a electro-magnetic lock ismounted adjacent to the plate on the frame of the door. The electro-magnetic lock firmly holds theplate mounted to the door, holding it closed until the power is removed by the reader, allowing thedoor to be opened.

Most electric locks are available in two configurations, Fail-Safe and Fail-Secure. Fail-Safe locksrequire power to hold the door closed and will release the door when power is removed. This typeof lock will open the door if a power outage occurs. This is desirable for doors used as emergencyexits. Fail-Secure locks hold the door closed automatically and require power to release the door.This type of lock is desirable for securing doors in high security applications. Electro-Magneticlocks are typically only available in the Fail-Safe configuration.

Electric locks are also available in a range of operating voltages. 12 volts DC or 24 volts DC arethe most common. AC power strikes are also available but are not widely used because of thedifficulty in connecting suppression circuitry (see Part 3.6.5.2) and the inability of providingbattery backup power in the event of power failure. If a 12 or 24 volt DC lock is selected, the samepower supply used to power the lock may be used to power the reader. UNDER NOCIRCUMSTANCES SHOULD AC POWER BE APPLIED TO THE APN-35!

22System Wiring


A typical electric door lock (strike) will require approximately 250 mA. (.250 amps) to control. Therelay contacts on all Apollo relays are capable of switching up to 24 volts DC at up to 2 amps. Ifthe particular locking device requires more that 2 amps to control, a separate, external relaycapable of switching the required amount of current must be installed.

The APN-35 provides an internal strike relay for each of the two possible doors. Each relay israted for switching 2 amps at up to 24 volts DC. Connection of this internal relay is covered in Part3.5.3

Wiring between the strike power supply, strike relay (internal or external) and the electric lockshould be of sufficient gauge to prevent excessive voltage drop under all circumstances.

ALL ELECTRIC LOCKS MUST HAVE A SUPPRESSION CIRCUIT INSTALLED TO PREVENTEXCESSIVE INTERFERENCE WITH OTHER SYSTEM COMPONENTS WHEN THE POWER ISREMOVED. SEE THE FOLLOWING SECTION FOR INFORMATION ON SUPPRESSIONINSTALLATION.

3.6.2 Strike Suppression Installation

Most electric locks consist of several components, one of which is usually a coil of wire that actsas an electro-magnet to either release the door (Fail-Secure) or hold the door closed (Fail-Safe).This coil of wire acts as a large inductor. When DC power is applied to a large inductor, energy isstored in the inductor. When the circuit is broken (power is removed) this stored energy isconverted to a very large voltage and attempts to travel down the wires connected to the strike. IFSOME METHOD IS NOT UTILIZED TO REDUCE OR SUPPRESS THIS VERY LARGEVOLTAGE, IT CAN CAUSE COMMUNICATIONS PROBLEMS, PERMANENT DAMAGE TO THESTRIKE RELAY, AND PERMANENT DAMAGE TO OTHER SYSTEM COMPONENTS!

The most common method of suppression used on DC power strikes is installation of a reversebiased diode as close a possible to the strike itself. Any type of general purpose diode (1N4001 –1N4006, etc.) will work

AC powered locks will not allow use of a diode for suppression. There are available suppressorsfor use with AC powered locks called Metal Oxide Varistors (MOV’s). These are sometimesincluded with the lock. If you wish to use AC powered strikes and a suitable suppressor is notsupplied with the lock, you must contact the manufacturer of the lock for information on obtaininga suitable suppressor. Connection of the suppressor should follow the instructions provided withthe lock.

3.6.3 Strike Wiring

The APN-35 includes internal relays for door strike control for each of the two possible doors.These relays are capable of switching up to 24 volts at up to 2 amps. If the lock installed on thedoor requires more than 2 amps to control, an external relay must be provided. The power that isprovided to the locking device (strike) through this relay may be connected to the same powersupply that is providing power the reader if the strike requires 12 or 24 volts DC. IF THE STRIKEREQUIRES A VOLTAGE OTHER THAN 12 OR 24 VOLTS DC OR ANY AC VOLTAGE, ASEPARATE POWER SUPPLY MUST BE USED.



The diagram below illustrates connection of a DC powered, Fail-Secure, door strike. This type ofstrike requires power to release the door. The power will be supplied through the normally open(NO) relay contact of the strike relay. No power will be provided to the strike until the readeractivates the internal relay. The reader will activate the relay as a result of a valid access request(card swipe, card swipe plus valid PIN, valid PIN entry only, etc.). The reader will alsopermanently activate the strike relay if commanded by the host software to be “unlocked”. Thereader will also activate the relay if the exit pushbutton is depressed.

3.6.4 AKM-10 External Relays

For the two Auxiliary relays of the APN-35, external relay modules AKM-10 must be used. TheAKM is designed to mount directly in most Apollo enclosures. A wire must be run from the properterminal on the APN (OUT1 or OUT2) to the RLY terminal on the AKM-10. It is also necessary tosupply power (12 or 24 Vdc @ 50mA) to the AKM. One AKM-10 should be used for each output.

Once power and the control wire for the AKM-10 have been connected, the AKM-10 providesthree relay contacts for connection of external devices. Similar to the onboard strike relays of theAPN, Normally Open, and Normally closed poles are provided as well as a common pole for therelay.

3.7 General Alarm Inputs

The APN-35 provides one general alarm input. The wiring to the input should be made withtwisted pair 24 AWG wire. If these input is not used, it should be ‘jumpered’ using a 1” (25 mm)long piece of wire connecting the two terminals to form a closed circuit. This will prevent an alarmcondition being reported to the host.

3.7.1 Cabinet Tamper


Cabinet Tamper Input: TB6

This input is for connection to a switch located on the cabinet in which the APN-35 is installed todetect unauthorized access to the panel. This is a normally-closed contact. In the event of atamper condition, the exit push buttons will not function on the reader connections. This conditionwill last until one minute after the tamper has ended. This feature restricts the ability to have easycontrol of all the doors by merely shorting the EPB input.

4.1 Communications

The first thing that must be verified at the card reader is the RS-485 communications. If the readeris unable the communicate to the controller, most other functions will not work. Communicationsshould be verified observing the port activity LED (D15), which will blink when communication isactive (see Part 2.4).

4.2 Reader / Keypad

The reader function can be verified after communications are functioning properly. The hostsystem must be configured for each of the readers on the APN-35 to be used, and with the correctcard format. The card format is determined by the actual cards that will be used. After configuringthe card format at the host, placing a card in front of the reader should generate an accessmessage on the host computer. If the message is “Access Denied” the reason for the messagewill indicate further steps to be performed. “Access Denied – Wrong Facility Code” will alsodisplay the actual facility code on the card. This information should then be entered to the hostcomputer system. “Access Denied – Not in File” will display the actual card number of thepresented card. This card should then be added into the employee database of the host system.”Access Denied – Access Level Error” indicates that the cards is entered into the system but theAccess Level assigned to the card does not allow access to the particular door at this time.

On readers with integral keypads, the keypad may be verified by setting the reader into the Cardand PIN mode. After presenting a valid card, the reader should flash the yellow LED (if installedreader supports 3 color LEDs). This indicates the reader is waiting for a Pin entry. Enter a validPIN using the keypad and press the “ENTER” key. Access should be granted.

4.3 Input Zones

All alarm inputs should next be verified. Opening the Door Contact input should generate animmediate “Forced Open” alarm. Closing the Exit Pushbutton input should release the strike relay.NOTE: the Exit Pushbutton input will not function if the reader interface is in tamper (TamperContact=Open) and also one minute after the tamper condition is secured. The reader may alsobe configured (via the host) to not activate the strike relay when the Exit Pushbutton is depressed.In all cases the reader should not report “Forced Open” immediately after pressing the ExitPushbutton. The Aux Alarm inputs (if used) can be verified next. Some system will not allow useof the second Aux alarm. Opening the Aux alarm input should result in a message on the hostsystem. Unused Aux alarm inputs should be terminated.

4.4 Output relays

The internal strike relays should energize any time a valid card (or PIN) is presented and themessage “Access Granted” appears on the host. The reader may be set to the “Unlocked” modeat the host to permanently energize the relay for test purposes.
