TeraAccess System Components

INTERFACE CONTROLLERS

Тhe interface controllers serve to make the connection between the computer and the access controllers. The systems can support more than one interface controllers connected to the computer. Each controller is assigned a 4 digits numbers which corresponds to the license key used to activate the software. Depending on the configuration the controllers can be of type RS232/RS485 or USB/RS485. Each can be opto-isolated or not. Opto-isolated controllers are recommended in systems where more than one controller is used. Interface RS485 allows the connection of up to 31 access controllers to one interface controller. The access controllers are connected subsequently using an FTP cable. The length of the connecting cable should be up to 800 m.

The two ends of the 485 interface BUS should be terminated with a resistor of 120 ohms.

The power supply of +12 V is supplied to pins 7 and 8 of RJ45. Thus in small systems with up to 2-3 access controller and length of cable up to 50 there is no need for additional power cord.

The interface controller is supplied with power via the USB port of the computer. The +12 V power supply to the access controllers is returned through pins 7 and 8 of the RJ45 of the interface cable.

ACCESS CONTROLLER - АCT120 O

The access controllers АCT120 O (Office) are mounted at the access control points. They support 2 terminals and 1 relay output. The communication with the computer is via RS485 interface. Inputs from the two terminals are used to operate one relay. This mode of work is applied in office environment to manage an electromagnetic lock (or magnet) by operating with two terminals. The terminals are usually mounted at the two sides of the door. One is marked as “Entrance” and the other – as “Exit”. When the relay is activated it supplies +12 V to the electromagnetic lock thus making the connection easy. When you need to manage other devices (and not electromagnetic locks) you need to remove jumper 03 (located right next to the relay). Thus outputs “electromagnetic lock” and “power supply” become outputs of the normally open contact of the relay. The power consumption of the access controller in this case is small and can be supplied using the interface cable. When access controller АCT120 O is connected to the system two consequent addresses are automatically assigned to it. It is recommended that the first address is set in the software as “Entrance” and the second is set as “Exit”. Terminal 1 corresponds to the less significant (LS) part of the address and Terminal 2 – to the most significant (MS) part of the address. To set the LS address of the controller use the button WR located on the PCB and the indicators of the terminals. When you assign the LS address, the MS address will be assigned automatically as “LS address +1”. To set the LS address of access controller ACT120 Turn off the power supply and press button WR located on the PCB. Supply power while keeping the button pressed. The red LED will blink twice with one short and one long blink to indicate the initialization of the controller. After that the red LED starts blinking periodically per 1 second. Each blink corresponds to increase in the address with a step of 1. When the desired address is reached stop pressing the button. The controller will switch to working mode. ATTENTION! The setting will be made to the LS address. The MS address will be set automatically as “LS address+1”. Example: If you need to set address 3 and 4 to АСТ 120 О: Turn off the power supply and press button WR on the pcb. Turn on the power supply and follow the blinking of the red LED. Wait for one short and one long blinking (initialization) and three blinkings after that (assigning address 3). Stop pressing the button. The LS address will be set to 3 and the senior address will be set to 4 (3+1).

ACCESS CONTROLLER - АCT120 Т

The access controllers АCT120 Т (Turnstile) are mounted at the access control points. They support 2 terminals and 2 relay outputs. The communication with the computer is via RS485 interface. Inputs from the two terminals are used to operate two relays (relay 1 and relay 2). This mode of work is applied to manage barriers and turnstiles. The relays are activated by supplying +12 V to them thus making easy the connection of devices. If you need to manage other types of devices remove jumper 03 (located next to the relay) and jumper 04 (a wire jumper located next to relay3). Thus outputs +12V , “el. magnet 1” and “el. magnet 2” , +12V become normally open contacts of relay 1 and 2. The power consumption of the access controller in this case is small and can be supplied using the interface cable. When access controller АCT120 T is connected to the system two consequent addresses are automatically assigned to it. It is recommended that the first address is set in the software as “Entrance” and the second is set as “Exit”. Terminal 1 corresponds to the LS address and Terminal 2 – to the MS address. To set the LS address of the controller use the button WR located on the PCB and the indicators of the terminals. When you assign the LS address, the MS address will be assigned automatically as “LS address +1”. To change the address of the ACT120 T use the procedure described for ACT120 O. When working with turnstiles there is the possibility to switch off the relays (no matter the settings in the software) by sending a signal to the controller. This functionality makes sure that 2 persons will not pass through the same access point. The controller switches off the relays when the input detector and the GND are connected or when logical 0 is supplied to the input. The logical 1 is +12V.

ACCESS CONTROLLER - АCT120 Н

The controller ACT120 H (hotel) is mounted at the access control points. It is designed for use in hotel access systems but can be used with other applications as well. The controller manages 2 terminals, 3 relay outputs and 3 inputs. It has nonvolatile memory which can save the information for up to 14 cards. The controller is connected to the computer via RS485 interface through an interface converter. The controller corresponds to one address in the system. ACT120 H can perform the following logical functions:

1. Terminal 1 controls relay 1 – used for restricting the access in a hotel room. When relay 1 is activated, +12 V is supplied to connector “lock”.

2. Terminal 2 controls relay 2 – used for energy saving. Only the cards saved to the nonvolatile memory of the device can be used to control relay 2. The relay is activated when a valid RFID card is present in the range of the terminal. The relay switches off automatically 15 seconds after the card is removed from the range of the terminal.

3. Relay 3 – has different applications. Can be controlled through the software. 4. Inputs 1,2, and 3 – serve to transmit signals from external sensor to the software. They have

numerous applications such as connecting panic buttons, alarm detectors, etc. The setting is made through the software. The logical levels of the inputs are 0 and 5 V.

5. Panic functionality - when panic signal is activated (as set in the software) the controller sends a signal to the computer. The ENTER terminal starts blinking and makings short sounds. The controller periodically activates relay 1 thus insuring easy access to the room.
