TrueAlarm Analog CO Sensor Standard Base


Simplex 06501227 TrueAlarm CO Sensor Base  4098-9770

The Simplex® 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. The CO sensor can be enabled/disabled, used in LED/Switch modes and custom control, and can be made public for communication across a fire alarm Network.

Carbon monoxide (CO) is an odorless, colorless, tasteless gas produced by the incomplete combustion of heating fuels such as wood, coal, heating oil, and natural gas.  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.

This base is compatible with several different Simplex TrueAlarm sensors, including the 4098-9714, 4098-9754 and 4098-9733 sensors.  This base will ensure your system remains operational at all times, so order yours today.
