G Series carbon monoxide sensors maximize energy savings, while ensuring optimal ventilation in parking garages and other mechanical areas. The sensors allow ventilation systems to be controlled by the amount of CO present in a location. The G Series detects fluctuations in CO levels, and it signals air systems to provide an inlet of fresh air optimal for the space at a given time. In this manner, the ventilation fan does not need to run continuously, saving energy and reducing maintenance costs. Upon alarm, the G Series will alert those in the area with both an audible and a visual alarm.
The G Series devices are equipped with a relay contact that closes when CO level is below 25 ppm and opens when the CO level is above 25 ppm. Sensor removal, power interruption, or cut wires cause the external contactor (normally closed) to open and start the fan. Minimum relay cycle time is 3 minutes to prevent fan short-cycling.
Audible Alarm: 85 dB alarm sounds if CO level rises above 100 ppm for 30 minutes.
