Specifications

FunctionThe Slave Expansion Module allows Comfort II to be expanded beyond 16 Inputs and 16 Outputs. Each Slave contains 8 Inputs and 8 outputs, which can be expanded by connecting LEM01_M2 (8 inputs, 8 outputs) or LEM02-M2 (8 inputs). There are 2 models; SEM01-M2 with built-in regulated power supply, and SEM02-M2 without regulated power supply. SEM01-M2 is the same size as the main Comfort panel. SEM02-M2 is much smaller, and can be mounted above a Comfort PCB to save space. SEM02-M2 requires an external 12V 1.5A DC power supply.

The SEM01-M2 supplied in the standard metal enclosure is called SEP01 (Slave Expansion Panel).

SEM02-M2 is normally suppllied as a printed circuit board assembly, without enclosure.

Other than the physical size and input power requirements, the function of SEM01-M2 and SEM02-M2 are the same.

Differences between SEM01-M2 and SEM02-M2

Figure 1 - SEM01-M2 Printed Circuit Board

Figure 2 – SEM02-M2 Printed Circuit Board

SEM01-M2 consists of 2 printed circuit boards joined together at the centre: A Digital section (on the left in figure 1) and a Power Supply section on the right in Figure 1

3


SEM02-M2 is the SEM01-M2 Digital section without the Power Supply board.. Hence the 12V power supply for the SEM02-Me must be supplied from an external source, which may be a Comfort Controller or another SEM01-M2.

For SEM02-M2, the 12V supply is connected to 12V/COM. SEM02-M2 should NOT be used to supply power to other devices.

ICs

• U1 - Program IC. This IC contains the ‘firmware’ for the SEM’s embedded behavior. This can be replaced for firmware upgrades.

• U5 - RS485 Interface IC.

Connections

• AC 14V - Transformer Input connection (SEM01-M2 Only)

• BATT - 12V Battery Connection for Sealed Lead-Acid Rechargeable Battery (SEM01-M2 Only)

• Z1/COM/Z2: Zones 1-2 input connections




• 12V/COM/S12V: Unswitched and Switched 12V Supply (3 position terminal block) For SEM02-M2, the external 12V power source is connected to 12V/COM.

• OP1/12V/OP2 – Outputs 1,2 and Common 12V




• KA/KB: RS485 Bus. This is conected via twisted pair to the same terminals of the Comfort panel.

• TAMP/COM- Connection to Tamper Switch. Short terminal block with wire-link if tamper Input is not used.

• SRN+/SRN- : Connection to external Bellbox

• LEM: Connector Point for LEM Plug-in board

• RS485 - 4 way header for RS485 4 way cablle

Jumper Settings

• Reset Switch. This switch resets the SEM and is normally not used.

• JZ1 -JZ8 3x8 way header - Insert shunt in the position nearest the terminals for the corresponding Zone 1 to 8 if no EOL resistor is used for the zone. Insert a shunt in the position away from the terminal block if Double EOL resistors: 2K7 connected in series and 4K7 is connected across the contact.

• J14 - (2 position header) -Short for normal use. Remove when using MPU plug-in Upgrade firmware.

• SRNTMP - Short header if Siren is not connected, this suppresses the siren trouble alarm when the siren is disconnected.

• S12V – shunt if S12V output is not to be switched. This means S12V is continuous 12V output andn cannot be switched off

• ID - RS485 Address setting switches for SEM.

Location of Panel

The system should be mounted in a dry area, with access to an unswitched AC power source and incoming telephone line.

Mounting

Do not remove printed circuit boards from the cabinet as they are may be damaged by static electricity and incorrect handling.

Remove the knockout holes and mount the cabinet to the wall. Do not connect the transformer and backup battery until all other wiring is complete. Take precautions against damage by static discharge by using an anti static wrist strap tied to a suitable earth point.

The 12V supply of the SEM02-M2 can be taken from the Comfort 12V auxiliary 12V output provided the total current required by the SEM and Comfort and the devices connected to them do not exceed 1A

The SEM can be mounted up to 1 km away from the main Comfort panel provided twisted pair (CAT 5 ) cable is used

A Local Expansion Module (LEM) may be mounted on top of a SEM PCB using 4 standoffs.

SEM01-M2 Power Supply

The SEM01-M2 may be powered by its own transformer and backup battery. This will allow each SEM to supply 1A auxiliary power, independent of the main Comfort panel.

Connect the two RS485 data lines KA and KB to the corresponding terminals (KA to KA, KB to KB) on the Comfort panel. If the SEM has its own transformer and standby battery, no other connection is required except that the 0V of all the sems and Comfort should be connected. In this configuration, the distance between each SEM and the Comfort control panel may be up to 1000 meters provided twisted pair (CAT 5) cable is used

TransformerFor UL installations, use a UL approved 16.5V 40 VA transformer (manufactured by Mascom, Type ATW 1640)

Connect the transformer output wires to the AC IN (JP1) terminal blocks through the mains inlet knockout hole. The plug-in transformer should be connected to an unswitched power supply outlet. Connect a 16 AWG green-jacketed solid conductor ground wire from the earth terminal on the studs provided on the enclosure to a metal pipe, grounding rod or other established earth ground for protection against lightning-induced surge.

The transformer secondary output is connected to the AC IN (JP1) terminals.

✔ For UK Installations: The mains transformer is supplied in the enclosure. The mains installation should be carried out by a qualified electrician in accordance with Electrical Wiring Regulations (BS 7671). As this is a permanently connected equipment, the fixed wiring must have a readily accessible disconnect device, e.g. isolation switch.

✔ Ensure that continuous current supplied from the AUX terminals and outputs is less than 750 mA.

✔ Do not share the transformer secondary with any other equipment. Do not connect the transformer until all other wiring is completed.

Backup Battery (JP2)Connect a 12V 7 AH sealed lead-acid battery to the BATT (JP2) terminals. This will give more than 24 hours of standby power to the system if 200 mA or less of auxiliary current is used. The LEM Expansion board requires less than 35 mA. Connect the positive terminal of the battery to the + terminal of the BATT connector and the negative terminal of the battery to the - terminal. The battery provides standby power to the system in the event of power failure and supplies additional current when required, e.g. to drive the siren during an alarm. Do not connect the battery until all wiring is completed. The battery current is limited to 2.5A by a resettable fuse (F1).

6


✔ For UL985 installations, two 7AH batteries may be connected in parallel to provide continuous 24 hours standby operation for current of 500 mA. A special 2 ft battery harness (HN02) is available for this purpose. If the current is kept to 200 mA, a single 7 AH battery may be used to provide 24 hour standby.

SEM02-M2 Power Supply

If the SEM is powered by an external power supply and backup battery, each SEM can supply 1A auxiliary power, independent of the main Comfort panel.

Connect the two RS485 data lines KA and KB on JP8 to the corresponding terminals (KA to KA, KB to KB) on the Comfort panel. If the SEM has its own power supply with standby battery, no other connection is required. In this configuration, the distance between each SEM and the Comfort control panel may be up to 500 m.

If the SEM power supply is obtained from the main Comfort panel (see next section “Power Supply from Comfort Panel”), then two more wires need to be connected for 12V and Ground

Power Supply from Comfort Panel

If the combined current required by the Comfort panel and its auxiliary 12V outputs combined with the SEM and its outputs does not exceed 1A, then the SEM may be supplied from the 12V auxiliary output (12V terminal) of the Comfort panel instead of the transformer through JP1. Connect the 12V from the Comfort panel to the 12V terminal of the SEM as shown in the figure below.

✔ Do not connect the 12V to the Comfort aux 12V and the transformer to JP1 at the same time

✔ Run the 12V and COM to each SEM from the Comfort panel in “star” configuration. Do not connect the 12V/COM of each SEM in series, in order to minimize wire resistance on the supply line. Keep the resistance of each 12V and ground line to under 2 ohms each.

Cable Routing / Requirements

The minimum cable type to be used for detection devices, sounders should be 6-core alarm cable (7/0.2mm). This has a resistance of approximately 8 ohms per 100 meters. Screened CAT 5 cables are preferred for Keypads, Door Stations, each run from the panel separately. Where spare conductors are available in multicore cable runs, they should be used to double-up the 12V power supply cables to the each control station to reduce circuit resistance and further improve current performance.

Ensure that all RS485 communication lines and detection circuit cables are kept away from mains supply cables.

Screened cable may be essential where system wiring is to be run adjacent to cables that produce Radio Frequency Interference or are switching high-current loads, such as industrial switch gear and computers etc

Input and Output Expansion with SEMs

Without any SEMs, the Comfort control panel with a LEM (Local Expansion Module) may be expanded to 16 inputs and 16 outputs. Only 1 LEM may be connected to the Control panel, and this must be mounted inside the same metal enclosure. LEM02 has 8 inputs without outputs, and LEM01 has 8 inputs and 8 outputs.

To expand the number of inputs and outputs beyond 16, SEMs must be used. Each SEM has 8 inputs and outputs. Each SEM may be connected to one LEM02 or LEM02 to provide a maximum of 16 inputs and 16 outputs for each SEM. The LEM may be mounted on top of the SEM02-M2 using 4 metal standoffs screwed onto the 4 mounting holes on the SEM02-M2 PCB.

Up to 3 SEMs may be connected in a Comfort system, giving a maximum of 64 inputs and 64 outputs, provided a LEM is used for the control panel and each SEM.

Each SEM has an ID, set by headers. Refer to the table in “Jumper Settings” section. If only one SEM is connected, then the ID must be set to 1. The next SEM added must be 2, and the next should be 3.

The figure below shows the ID settings for each SEM, and the zones and output numbers associated with each SEM and LEM.

Figure 3 - Connecting SEMs and LEMs

The 16 zone LEM03 with no outputs cannot be used with the SEM or the Comfort panel when there are SEMs in the system. This LEM03 can only be used with a Comfort system without any SEMs

Programming

The SEM does not contain any program settings or program memory. All programming settings are contained in the main Comfort panel.. The SEM obtains the zone and output settings from the Comfort control panel when it comes on line, and whenever the settings are changed via keypad programming or download from the PC, and whenever the control panel is reset (by pressing the RESET button or from Engineer menu 7,4,2

Refer to the Programming Worksheet (FS18) for programming information.

✔ If the SEM is installed, make sure that the LEM03 is disabled in Location 40 (you can also do this in the CSXpress Modules screen). The 16 input LEM03 and SEM cannot be used at the same time in a system

Alarm Reporting

Each SEM monitors the following conditions and reports them to the Control Panel

Low BatteryWhen the battery voltage drops to a level (approximately 11 V), a Low battery condition is reported to the main Control panel. This is reported on the Event Log and announcement as “Battery Warning, id”, where id is the RS485 ID, i.e. 33 = SEM 1, 34 = SEM 2, 35 = SEM 3. A low battery condition on the Control panel will be reported as ‘Battery Warning, 1”.

If the SEM is supplied from the Comfort panel, a Battery warning is reported when the incoming supply voltage is low.

Mains Failure is not reported by the SEM as this may result in multiple alarms if there is a general mains failure

TamperThe Tamper input is monitored as a 24 hour alarm, and reported to the Comfort Control panel as “Tamper Alarm, id” The meaning of id is as explained above.

Input and Output connections

Refer to the appropriate sections in the Comfort Installation Manual for End-of-Line resistors
