Comfort Slave Expansion Module PCB
[SEM02-M2] - Stock: 0

CE Approved
The Comfort Slave Expansion Module (SEM) 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).

The SEM02-M2 does not have a power supply and can be mounted above a Comfort PCB to save space. The SEM02-M2 is normally supplied 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.

Zone Inputs

  • 8 fully programmable zones expandable to 16 with Local Expansion Module(s) (LEM)
  • Each zone configurable for 0 or 2 end-of-line resistors
  • Up to 32 predefined Zone types to simplify zone configuration
  • Surge/Over voltage protection for each zone

Open-collector Outputs

  • 8 open collector outputs on main board, expandable to 16 with Expansion module(s).
  • Each output can drive an external relay or infrared transmitter for remote control appliances.
  • Selectable Pulsed or Steady output activation.
  • Programmable Infrared signals (air conditioners, home entertainment, etc.) at any output.
  • Over voltage and Surge-protected outputs.
  • Maximum 300 mA current limit for all 8 outputs on SEM. 300mA current limit for all 8 outputs on LEM01-M2s

Power Supply

  • SEM02-M2 requires 12V DC 2.5A Amps with 6.5 AH sealed lead acid standby battery (Cytech P/N PSU01 or equivalent).
  • 12V and S12 outputs are protected by a resettable fuse 1.8A
  • Quiescent current 50 mA max, 25 mA typical (14V DC supply)

Auxiliary Supply Outputs

  • 12V unswitched supply
  • S12V switchable supply (programmable for reset operation)
  • Note: Both 12V and S12V auxiliary supplies and 8 Outputs have a combined continuous current limit of 1A, protected by a common resettable fuse of 1.3A

System Supervision

  • Individual Zone tamper (open-circuit or short-wiring) with 2 end of line resistors
  • Dedicated 24 hour Tamper input

Input/Output Expansion

Each Slave Expansion Module can be expanded using one of the Local Expansion Modules
  • LEM02 - Local Expansion Module 8+0 (8 zones, 0 outputs)
  • LEM01 - Local Expansion Module 8+8 (8 zones, 8 outputs)
  • LEM03 cannot be used with SEM01 or SEM02
Each Slave can support a total of 16 inputs and 16 outputs. 3 SEMs can be installed in a Comfort System, giving a system capacity of 64 inputs and outputs. The LEM03 (16 input 0 Output LEM) cannot be used with a SEM, and cannot be connected to the main Comfort panel when a SEM is also installed.

Size

SEM02-M2: 120 x 130 mm. Mounting holes are provided on top of CM9000 PCB.

Alarm Outputs

  • Siren (12V) Output
  • Speaker output for Internal speaker 8 ohm to 32 Ohms - From firmware SEM 5.167
  • Strobe (12V) Output - From firmware SEM 5.167
