Zeta SmartConnect Multi-Loop Card Module (MKII Protocol) (SCM-LCM)

The Zeta SCM-LCM is a plug-in loop card module for Zeta SmartConnect multi-loop fire alarm panels (for example the SMART6 expansion port panel). It powers and handles communications for one loop of MKII protocol analogue addressable devices, continuously monitoring their status.

Up to 250 addresses can be connected to the loop. Devices can be addressed by 8-way DIP switch or soft-addressed with the MKII-TOOL handheld programmer, and the AUTO-LEARN facility lets the panel learn which devices are installed and helps locate loop wiring faults.
