The CO1224T is a 12/24 volt, 6-wire, system-monitored carbon monoxide detector with RealTest (R) Technology.

Addressable Mini-Monitor Module, One Style B (Class B) Initiating Device Circuit for Monitoring N/O contact devices, does not include a polling LED

The MMF-301 monitor module can be installed in a single gang junction box directly behind the monitored unit. Its small size and light weight allow it to be installed without rigid mounting. The MMF-301 is intended for use in intelligent, two-wire systems where the individual address of each module is selected using rotary switches. It provides a two-wire initiating circuit for normally open contact fire alarm and security devices. This module can be used to replace an M301 module in existing systems.
