System Sensor COSMOD2W 2-wire Smoke CO Detector Interface Module

System Sensor i4 Series 2-wire Smoke/CO Detector Interface Module The COSMOD2W is the interface module that is required if you are using System Sensor's i4 series of Smoke/CO detectors. The interface module will allow you to connect in up to 12 i4 Series or compatible i3 Series smoke detector models. They use only 2 to 3 zones on the panel's control board. You'll have your smoke zone, your carbon monoxide zone, and an optional trouble zone if that's the way you'd like to set it up. Another really nice feature of the COSMOD2W is that it can be used to act as a traditional reversing relay would by initiating all of the sounders in the connected detectors so that no matter where the fire starts; other areas of the building can be notified. This module is compatible with most alarm control panels and mounts to a 4 11/16" square back box for easy installation.   Installation Sheet Data Sheet
