Release Mechanisms

The Flame Shield Fire Curtain is available with two specifications of control panel:

P80 Standard Control Panel

  • Easy set-up and connection.
  • Automatic detection of motor end limits.
  • Close type options – driven or gravity close as standard.
  • Dead man operation – key switch, push buttons etc.,
  • Link to fire alarm, will open or close the fire curtain on receipt of a signal from the fire alarm. (Volt Free signal required)
  • Facility within the panel for an emergency escape / Fireman’s switch. This would only operate if there is mains available.
  • 24 Volt battery back up as standard (5 hour stand by time), can be used in the event of power failure.
  • Facility for Alarm Test.
  • Gravity fail safe available dependent on type of motor used.

Operational Overview

  • The P80 generally operates via a wall mounted 3 position key switch. Under normal operation the curtain is opened and closed via this key switch.
  • Fire Conditions - The panel continuously monitors the normally closed alarm input terminals. If the terminals go open i.e. alarm triggered, the shutter will close under power or via gravity to the fully closed position. Providing the alarm signal is cleared you can re-open the shutter accordingly.
  • Facility to link audio or visual warning devices, a siren or flashing light can be added, during the time the alarm input is open the 24Volt DC alarm is activated to allow these units to be added.
  • An emergency override alarm button can be used. This will allow you to open the shutter even if the alarm signal is still present, effectively if the alarm signal is still active. Once you remove the signal i.e. the override button is released, the shutter will re-commence its close cycle.
  • The P80 unit has a test function input that allows regular testing of the control / curtain.
