Overview

Simplify fire and CO detection integration while improving occupant safety with the System Sensor COSMOD2W i4 Series 2-Wire Interface Module. Designed for use with COSMO-2W and compatible i3/i4 detectors, this interface lets you connect up to 12 detectors to the fire alarm control panel using only 2–3 zones, cutting wiring complexity and conserving panel resources. The module reports distinct smoke and carbon monoxide events to the panel and can interconnect all detector sounders so a single alarm condition provides immediate, site-wide notification. Built for installers, the COSMOD2W mounts to a 4 11/16" square back box and uses SEMS screw terminals for secure, repeatable connections; it runs on 35V DC and includes LED indicators for loop status, trouble, maintenance and end-of-life. Ideal for commercial and residential security and fire alarm projects, this wired interface module streamlines monitoring, reduces service time, and enhances system reliability. Add the COSMOD2W to your surveillance and safety infrastructure for coordinated smoke and CO monitoring—order now or contact us for specification support.
