WARNING: Cancer and Reproductive Harm –


Detect Carbon Monoxide ASAP

Designed for use with a wireless ready Elk M1 controller (sold separately), the Elk 2-Way Wireless Carbon Monoxide Detector integrates into an Elk home system. When the detector detects potentially dangerous levels of carbon monoxide (CO), it flashes the red alarm LED immediately and then sounds a loud alarm if the CO persists. It can also automatically notify your central monitoring station. This ensures the safety for the entire family and facilitates an immediate emergency response to prevent carbon monoxide poisoning.

  • Communicates to M1, activating hardwired sounders and alert to Central Station
  • AudioLink smartphone app simplifies field testing and provides diagnostic data
  • Alarm Memory provides warning when CO gas is detected during the unoccupancy of a home/property
  • Loud built-in sounder, 85dB(A) at ~10 feet (3m)
  • LED indicators provide clear visual indication of alarms, faults, power and RF acknowledgment

The Elk 2-Way Wireless Carbon Monoxide Detector features AudioLink, a free mobile app (iOS and Android), which allows an authorized person to download information from the detector. The AudioLink app provides:

  • Peak CO level detected
  • Alarm activations, levels of CO and when events occurred
  • Background levels of CO
  • Age/run-time of the CO alarm
  • Test button activations
  • CO sensor status

Alarm Memory Technology

The Alarm Memory feature will warn you when the carbon monoxide detector previously detected CO gas when your home/property was unoccupied. It provides two operation modes:

24 Hour Memory Indicators: After alarm, the RED LED will flash at different rates every 50 seconds depending on the level of CO detected (see Table C).

Memory Recall on Demand: To review the memory status after initial 24 hours, press and hold the test button, the red LED will flash in accordance to Table C.
