Fire Damper Alarm Detection

If no fire or smoke alarms are detected the damper is in its normal position.

This position is always powered.

In case of alarm (fire states "1" or "2") the "DamperCmd" is not powered and the damper will run into its fire position due to its spring return actuator.


The alarm can be detected with:


Motorized fire dampers have optional end switches in both, the normal and the fire positions.


If you have to change the contact type - see the chapter "programming hints".


With normally closed contacts the "FireAlarm" output will be triggered  if:


There is no automatic reset of the fire alarm. You have to connect a reset button input.


Integrated smoke detector

Smoke extraction dampers are usually driven automatically via smoke detectors.
Therefore any fire damper, whether it is passive or motor driven has an option to use an own smoke detector via the smoke detector input. When it is not used set it to "0".
