Know When Your Smoke/CO Detector Sounds An Alarm

Receive notifications via technology when your traditional hardwired smoke detector and/or your carbon monoxide detector sound an alarm by installing the Ecolink Firefighter Smoke/CO Audio Sensor, 319.5 MHz. This battery-powered sensor mounts up to 6 inches away from a UL-listed smoke alarm or carbon monoxide detector. It senses when an audible alarm sounds using its built-in microphone, and then transmits a wireless alarm signal to your network.

  • Converts a hardwired smoke or carbon monoxide detector to work with wireless alarm panels
  • Transmits status of Fire and CO alarms
  • Battery-powered up to 5 years (depending on usage)
  • Mounts up to 6 inches away from smoke/CO detector
  • Multi-color LED indicates status based on color of light and sequence of flashes
  • Detects Temporal 3 pattern or UL detectors, and detects 4 patterns of CO detectors

Installation Details

The FireFighter Sensor-Transmitter easily mounts to the wall or ceiling with the included hardware. It can be placed up to 6 inches away from the smoke/carbon monoxide detector as long as its small microphone holes are facing the detector.
