co2 sensors

· Then the CO2 sensor signal will be able to override the minimum to allow more fresh air to enter in relation to the CO2, this can be done as modulating or just set to a higher minimum when the sensor dictates that more fresh air is needed. There aren''t to many codes that will alow you to close off the outdoor air damper completely, and this can also hurt you in buiding pressure which needs to ...

Outside Air Dampers AutomationWiki

OUTISDE AIR DAMPER (Normal Mode of Operation) During normal operation, the AHU''s outside air damper modulates open or closed based on a signal from a return duct mounted CO2 sensor, with its setpoint set to 600ppm of CO2. Upon a rise in CO2 levels above setpoint, the outside air damper will modulate open, allowing more fresh air to enter the space.

Modulating Control of Fire Smoke Dampers in Smoke Control

· If the temperature at the damper reaches 165°F (74°C), the primary sensor opens and the damper springs closed. If the FSCS panel switch is set to Open, several actions occur. a. The primary sensor is bypassed reconnecting the common power to the actuator. b. Override relay 1 is made and Override relay 2 goes to normal. This causes the actuator to drive full open.
