Mircom’s CSIS-202A 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 CSIS-202A mounts in a 4” square electrical box.
The CSIS-202A provides two supervised isolator outputs. Under this configuration, if the in-suite audible device has a open circuit, the fire control panel will indicate a zone trouble.
