Flameshield Fire Curtains

Widely acknowledged as a market leader for both the manufacture and installation of engineered fire shutter solutions, A1S has now introduced the Flameshield fire curtain creating new boundaries in building design for fire compartmentation.

Discreet and lightweight - yet with a level of performance equivalent to fire shutters - the Flameshield fire curtain is housed in a small unobtrusive box, which can be mounted in a ceiling void. Even the slimline bottom rail of the roller style fire curtain fits neatly in place when the fire curtain is raised.

A1S offer a nationwide supply and installation service with comprehensive after sales support. Check below for the full specification.

SPECIFICATION

FLAMESHIELD FIRE CURTAIN

The curtains constructed to Warrington Fire Research Centre WARRES No 165694, the test is in accordance with clause 8 of BS476 part 22:1987.

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

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 24volt 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 endplate 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.

Operation - Electrically operated 1PH 240 volt AC or 24 volt DC

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.
