INTRODUCTION
The releasing device is a failsafe constantly energized solenoid mechanism. It is designed for use on
rolling fire doors and counter fire doors. Inside the mechanism, contact relays receive the alarm signal
from the fire alarm control panel. When the unit receives the signal, the power to the solenoid is cut,
releasing the fire door mechanism and hence closing the fire door. The alarm signal can be Form C dry
contact or 24VDC/VAC. A power interruption in excess of 10 seconds will release the solenoid
mechanism. The release has a 10 second delay on alarm, closed door detection capabilities, Form C
relay outputs for the status of release box and 24VDC power output for door close warning.
