Easily add CO alarms outside bedrooms and on every level of the home to create a wireless safety network. OneLink Wireless Alarms provide a cost effective solution when it comes to renovation and retrofit projects where interconnectability is a requirement. Easily interconnect between floors and new to existing construction wirelessly.

First Alert "OneLink" Carbon Monoxide Detectors and Alarms operate on a "mesh network"; a 2-way communication format that sends, receives and then re-sends the alarm signals. If the initiating alarm signal is blocked from reaching one of the alarms, the mesh network communication reroutes and re-sends the signal via the other alarms.

Cost Effective Retrofit & Remodel Solutions:
  • Wireless interconnect technology eliminates the need to pull wires through existing walls
  • Save an average of between $150 - $200 per alarm when compared to retrofitting hardwired alarms in existing walls or ceilings
  • Photoelectric sensing technology reduces unwanted nuisance alarms

Additional Features:
  • OneLink enabled alarm
  • Exclusive! Voice alarm with programmable location. Programmable with up to eleven locations.
  • Single button test/silence
  • Two silence features - can silence the low-battery chirp for up to eight hours or temporarily silence an unwanted nuisance alarm
  • RF Interconnect: reliable and secure radio frequency communication between alarms. 915 MHz frequency with 65,000 security codes and 3 channel frequency hopping.
  • Optipath 360 Technology - patented technology provides 360 degrees of direct access to the smoke sensor.
  • Perfect Mount - allows for easy alignment of alarm
  • Spread Spectrum Horn Tone - Lower and varying frequency makes it easier for the elderly with normal aged related hearing loss to hear the horn.
  • Latching Features: Alarm Latch - remembers which unit initiated an alarm. 
  • Low Battery Latch: Visually indentifies unit in low battery condition.
  • End of Life Signal provides audible notification alarms needs to be replaced
