Product Identification
Product Overview
The G Series carbon monoxide detectors measure CO levels and signal control systems to provide an inlet of fresh
air optimal for the space at a given time. G Series devices are equipped with a relay contact that closes when
the CO level is below 25 ppm and opens when the CO level is above 25 ppm (when used with a normally closed
contactor). Removal of the sensor, interruption of power, or cut wires cause the relay circuit to open and start the
fan. Minimum relay cycle time is 3 minutes to prevent fan short-cycling.
Audible Alarm: An 85 dB alarm sounds if the CO level rises above 100 ppm for 30 minutes.
