Fire Curtain

1 HOUR & 2 HOUR FIRE RESISTENCE

Curtains

Our curtains are formed from a fire rated fabric 0.65mm thick, stitched and hemmed using Kevlar and stainless steel thread, the unique 2 section bottom rail allows smooth operation of the curtain.

Fire Curtains

Barrel

Fire curtain barrels are manufactured from mild steel tube, tube size dependant on the overall size of the unit and deflection calculated to conform to British Standards, the barrel is mounted on 20mm high speed bearings and is complete with an enclosed tubular motor either 240 volt AC or 24 volt DC.

Safety Feature

Gravity fail safe, operable if there is a power failure or if the wiring becomes corrupt.

Guides

Fire curtain guides are constructed from 2.5mm mild steel plate in 2 sections, the front section of the guide is removable and allows repairs to be effected without dismantling the door. The guides are slotted for expansion.

Hood

The fire curtain hood is formed from 1.2mm galvanised steel plate and is slotted for expansion.

End Plates

The fire curtain end plates are formed from 2.5mm plate, depth of the plate is dependant on the overall height of the unit, the end plate has a formed motor compartment which will be packed with non-combustible material.

Finishes

The Fire curtain is standard grey, the endplates, guides, hood etc are powder coated RAL 9010 white as standard, other colours are available at an additional cost.

Motor

  • 24 volt tube motor

Operation

  • Electrically operated 1 ph 240 volt AC or 24 volt DC

Usage

  • Although the fire curtain is provided with a key switch, it is not recommended for daily use

Release Mechanisms

  • Linked to the fire alarm as standard, other means of activation available are fusible link, smoke detector etc.

Standard Control Panel (P80 Unit)

  • Easy set up & 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 the fire alarm, will open or close the fire curtain on receipt of signal from the fire alarm. (volt free signal required)
  • Facility within the panel for an emergency escape / firemans switch, this would only operate if there is mains available
  • 24 volt battery back up as standard (5 hour standby time), can be used in the event of power failure.
  • Facility for alarm test.
  • Gravity fail safe available dependant 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 curtain will close under power or by gravity to the fully closed position. Providing the alarm signal is cleared you can re-open the curtain 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 24 volt 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 it’s close cycle.

The P80 has a test function input that allows regular testing of the control / curtain.
