Multi Switch Box
Instruction manual v.1.00


Slican Multi Switch Box MSB-1102 it is device assuring cooperation between Slican PABX[1] and sensors, relays, alarm systems, paging systems etc.

Subscriber port in PABX should be configured as Sensor or Relay – depending on required function.

Power supply parameters.

MSB-1102 Structure

MSB-1102 is equipped with following input/output ports:

  • sockets AB1/AB2 type RJ11 for connecting 2 subscriber ports in PABX,
  • socket 2REL[2] (REL1/REL2) type RJ45 which includes:
    • sensor terminals (SNS1/SNS2) – configurable,
    • monostable relay terminals[3] – configurable,
  • socket ZAS – local power supply from external source.

Connecting and preparing for configuration

According above table MSB-1102 must be supplied from local power supply device in following operating modes:

  • Sensors: CCS mode
  • Relays: VON/VOFF mode


  • current downloaded from power supply unit in CCS mode - max. 20mA.
  • current downloaded in DCI mode - max.10mA per sensor.
  • relay terminal parameters (for NO/NC and VON/VOFF modes) - max 42VAC/0.5A, 42VDC/1A
  • Sensor activate voltage range - DCI and CCS modes - 5-30V[4]DC.

Warning! It is not allowed to direct controlling with 230VAC voltage. For this purpose, appropriate external relays, connected to 2REL socket should be used.

Certificate of conformity, proper equipement disposal


  1. MSB-1102 can be used with firmware version 4.10 or later. It can be used with Slican PABXes: CXS-0424, CCT-1668, MAC-Zero, MAC-6400.
  2. Device uses 2 independent channels. It means that simultaneously two functions can operate. Ex: 2 sensors, 2 relays or mix.
  3. Release pulse time is about 1 second.
  4. Attention: Polarity is important
