Simplex 4098-9770 CO sensor bases combine an electrolytic CO sensing module with a TrueAlarm analog sensor to provide a single multiple sensing assembly using one system address. Also, the CO sensor-enabled/disabled; used in LED/Switch modes and custom control, and can be made public for communication across a fire alarm Network.

Simplex 4098-9770 CO is also a byproduct of many materials experiencing unintentional fire or even incipient fire conditions. Monitoring of CO levels can warn of physically harmful concentrations; however, sensing of CO levels below the harmful level can also provide improved understanding of incipient fire conditions when evaluated in combination with photoelectric fire sensor information from the same location.

Carbon monoxide is an odorless, colorless, tasteless gas produced by the incomplete combustion of heating fuels.

Besides, CO sensor operation is similar to other TrueAlarm sensors (photoelectric or heat). It provides current analog values, average analog value, “No Answer” troubles, “Wrong Device” troubles, over threshold, concentration in ppm, and monitors for the presence of the CO sensor. Base mounted address selection allows the address to remain with its location; when the sensor removed for service or type change. Address access is from the front, under the removable sensor.
