Description

Mircom’s CNSIS-204 Non-Supervised Signal Isolator Module is designed for installations where disconnection of, or damage to an in-suite audible device will not interfere with the ability of audible devices in other dwelling units, public corridors or suites to sound on an alarm. The CNSIS-204 mounts in a 4” square electrical box.

The CNSIS-204 provides four non-supervised isolator outputs. Under this confi guration, if a short or open circuit occurs, the isolator disconnects the audible device from the circuit but it does not indicate a trouble on the fi re alarm control panel. In this confi guration, an open circuit in the suite does not indicate a trouble on the control panel.
