The interface module required to run i4 combination CO and smoke detectors on a 2-wire panel.
What it does
The COSMOD2W lets i4 and i3 series detectors talk to a fire panel, sending separate smoke and CO signals. It has four LEDs, an EZ Walk loop test feature, a 12/24 V nominal input and mounts to a 4-11/16 in square back box. Operating range is 14 to 122 F.
Works with
Required with COSMO-2W detectors on a UL 864 listed panel that can use the module. This is a commercial fire part, not meant for the residential Vista-20P.
Why you want it
EZ Walk lets one person verify loop wiring by checking LEDs at each detector.
