Principle of Operation

Normal operation: The damper control panel to monitor zone volt free contacts (normal closed) in the fire alarm panel, which will energise a control relay to provide a power supply to the dampers.

Alarm condition: On alarm detection, N/C fire alarm contact to open, which will result in de-energising the control relay to remove the supply to the damper control option allowing failsafe position to be achieved.
