Release Mechanism Options
Option One – Fusible Link
Activated via heat from local fire activation temperature normally 72 degrees centigrade.
Option Two – Auto reset solenoid release
Activated upon receipt of signal from fire alarm / smoke detector. Auto reset via “open” push button, once alarm signal is stopped.
Option Three – Fire door interface panels & repeaters
Activated upon receipt of signal from fire alarm / smoke detector. A time delay can be programmed in to the F.D.I. panel, where by the signal will be held from the shutter until the programmed time has elapsed. During the time delay the F.D.I. panel will flash “Fire Door Closing”, simultaneously an audible alarm will sound. Once the time has elapsed, the signal will then be sent to the solenoid, allowing the shutter to close under the controlled descent.
IMPORTANT FIRE SIGNAL REGULATION
Signal type required – 24 Volt D.C (minimum 0.5 amps, non polarised). A booster panel can be provided if the alarm system cannot provide correct signal, this unit is not included as standard.
