GD Series carbon monoxide sensors control
ventilation systems in parking garages and other settings where air
quality is a concern. Energy and maintenance costs are reduced by
running the ventilation fan only as needed, rather than continuously.
The relay output is normally-open to provide failsafe activation of the
ventilation fan in conjunction with a normally-closed fan contactor.
Both audible and visual alarms alert those in the vicinity of excess CO
levels. Relay Output: Relay contact closes when CO level is below 35ppm. Relay contact opens when CO level is above 35ppm. Removal of sensor, interruption of power, or cut wires cause relay circuit to open and start fan. Minimum relay cycle time is 3 minutes to prevent fan short-cycling. Audible Alarm: 85dB alarm sounds if CO level rises above 100ppm for 30 minutes. |
