The i4 Interface Module connects up to 12 detectors to a wide range of control panels using only 2 to 3 zones. It also interconnects the devices, so when one device alarms, they all sound.

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.

Main Features

  • Easily integrates up to 12 compatible detectors to a wide range of control panels
  • 2-wire module is compatible with COSMO-2W combination detectors and 2WTA-B smoke detectors.
  • 4-wire module is compatible with COSMO-4W combination detectors and 4WTA-B smoke detectors.
  • Sends distinct smoke and CO signals from i4 detectors to the panel
  • LED indication shows when a detector on the loop requires cleaning or maintenance (2-wire detectors only)
  • Initiates the EZ Walk loop test (2-wire detectors only)
