Carbon Monoxide Detector

(sniff out deadly gas leaks)

Carbon Monoxide is a gas that you cannot see, smell or taste. Deaths due to CO
poisoning most often occur at night, when everyone is sleeping. SimpliSafe’s CO
detector uses electrochemical sensing technology for highly accurate and early
detection of this invisible but deadly gas.

Dangerous levels of CO will trigger both the sensor’s internal audible alarm and
the siren in your SimpliSafe security system.

Our alarm monitoring plans give you the option to receive:

  • A call to alert you and emergency responders sent
    to your home to ensure you and your family are safe.
  • SMS & Email notifications automatically sent to your
    phone and to the phones of loved ones.

Our competitor’s model sells for $89.99. Ours is $49.99. How do we sell the highest quality
sensors at half the price? No middlemen
