System Sensor COSMO-2W I4 Series, 2-Wire Carbon Monoxide (CO) And Smoke Combination Detector

The i4 module allows up to 12 i4 Series or compatible i 3 Series smoke detector models to be integrated into a fire alarm panel using only 2 to 3 zones: a smoke zone, a CO zone and an optional trouble zone. Detectors sound Temp 3 for smoke and Temp 4 for CO events. The i4 module can be used to alarm all sounders in compatible detectors for smoke and CO events. When one detector detects smoke or CO and goes into alarm, all connected detectors alarm, offering the highest level of warning to the homeowner.

The i4 Series Interface Module mounts to a 411/16-inch square back box for quick and easy installation. Terminal blocks with durable SEMS screws ensure a reliable connection. It also has pre-drilled holes for easy mounting inside a metal enclosure. The i4 Interface Module allows i4 and compatible i3 smoke detector models (2WTA-B and 4WTA-B) to communicate with any listed fire alarm control panel capable of utilizing this module.

The i4 Interface Module provides LED status indication for the loop, displaying normal operation, loop wiring fault, smoke events, smoke maintenance (2-wire only), CO events, and CO maintenance/end-of-life.
