The CO sensors can go out of calibration, rendering the system ineffective and cause a harmful environment for occupants. Additionally, some sensors can’t read CO levels below a certain temperature. If a garage ventilation system is designed in a colder climate, there should be a built-in response to low temperatures that will override the exhaust fan to run at constant speed if the sensors ...
For all parking garage applications, the Senva TG Series sensors can provide protection and indication of CO or NO2. The TG comes standard with two stages of relays for exhaust and alarm activation. It can be used as a stand alone controller, utilizing the relay for exhaust fan operation, the output for direct control of a VFD, and the LEDs and buzzer for alarm indication.

The COSTAR® 24VC-e features an electrochemical sensor and a microcomputer-based CO … Get Price. Axial …
That is, when the sensor is contacted by carbon monoxide (CO) or nitrogen dioxide (NO2) a change in voltage happens which triggers the fan to activate. As the sensor is contacted by gas over months or years, these chemicals begin to wear out and they no longer trigger the fan at the proper concentration of hazardous gases. For that reason, the manufacturer’s require that the sensors be ...
