Kidde KN-COSM-IB

The Kidde KN-COSM-IB High Voltage Hardwired Smoke and CO Detector provides valuable life-safety protection for a home or business. The device uses an ionization smoke detector and an electrochemical sensor for detecting carbon monoxide gas. It offers a fast response for triggering alarms.

Please note that as 120V high-voltage device, the Kidde KN-COSM-IB should not be directly wired with any type of alarm system. This type of sensor is generally only meant to serve as a local alarm. If a user does want to integrate one of these sensors with their system, they will need to use a takeover listening module. Alarm Grid sells life-safety takeover modules for 319.5 MHz systems, for 345 MHz systems and for 433 MHz systems. Alarm Grid strongly recommends that only trained professionals and electricians install this type of high-voltage device.

As an ionization smoke detector, the Kidde KN-COSM-IB is best-suited for detecting the smaller fire particles produced by flaming fires. And since a fire also produces CO gas, it will cause that sensor to activate as well. The CO and smoke sensors will then accurately work together in order to determine if the situation is a real emergency or just a false alarm. The constant communication between these two sensors helps to ensure the best possible performance.

Upon activation, the sensor will begin producing loud tones, as well as spoken verbal warnings indicating the type of emergency. The device also provides alerts for low battery and prior detections of excessive CO levels. The sensor is capable of producing sounds of up to 85 dB. It uses 120VAC power and two AA batteries for backup. It measures 5.6" in diameter, and it is 1.8" deep. Up to 24 of these devices can be interconnected for a hardwired fire alarm system. But only 18 of these devices can be initiating for the rest of the setup.
