FC240 - FIRE RESISTANT CURTAINS

FC240 curtains incorporate the latest technology to allow gravity fail safe operation. The integral tubular motor and the motor control circuit together provide a current limiting facility for the upper curtain position and back EMF generation for the controlled fail safe descent.

Fire and test deployment is always by gravity, even when the mains and battery supplies are available. This system will operate under worst case (mains and battery failure) conditions.

This product is not designed for frequent use, this product is designed to remain open during normal use and only to be closed during a test or an emergency situation.

Product Performance

Complete product tested to BS476: Part 20/22, and achieved a rating of DA (1000°C, above 270 minutes). The fabric has a fire propagation index I=3.2 when tested to BS 476: Part 6. It is therefore rated Class 0 to the UK Building Regulations Approved Document B 1991.

The FC240's wire reinforced fabric was subjected to a heat flux density test. The following results were recorded at 1.0m away from the curtain:

  • 15 Minutes - 1.6KW/m2
  • 30 Minutes - 2.6KW/m2
  • 60 Minutes - 4.4KW/m2

From the above data it can be calculated using a formula from the SFPE Handbook, section 2, that it would be possible for building occupants to safely pass a 6.0m wide Guardian fire curtain at a distance of 1.0m after a period of 60 minutes.

Fitting Configurations

The curtains must be fixed to appropriate masonry/concrete or steel supporting constructions that have a fire resistance of at least that specified for the fire curtain and are capable of maintaining adequate support for the required periods of up to 240 minutes.

  • Revel fixed
  • Face fixed

The box and the guide rails can be face and or reveal fitted. The box design features a removable access panel; access will be required to allow the product to be maintained.

Standard Specification

Controls

Operation of the curtains is via the group control panel which can either be mounted adjacent to the fire curtain head box within the ceiling void, allowing access for maintenance, or mounted in a remote position from the curtain. The panel requires a local 240v ac supply rated at 3 amps via an unswitched fused spur on a maintained supply installed by others. For operational purposes the G.C.P. must be connected to a normally closed volt free contact within the fire alarm control panel configured to open on fire and fail safe. Each control panel is capable of operating up to six rollers and includes battery back up which will maintain the curtains in their retracted position for a period of three hours during a mains failure. It is also possible to manually operate the curtains for twenty cycles during this period.

Should the battery voltage fall below a pre determined limit, a low voltage cut off circuit will activate the curtain, which will descend in a controlled manner under the power of gravity.

Dimensions of control panel: 145 mm H x 250 mm L x 50 mm D

Motors

The fire curtain is powered using a 24V DC tubular motor which is supplied as standard with a 4m 7 core cable. The motors and control panels feature controlled descent or gravity fail safe in the event of a signal from a fire alarm or a power failure.

Guides

Guides 2mm extruded steel 100 mm x 50 mm – When face fitted the guides have a 50 x 50 mm angle fitted to the back of the guide.

Curtains

Curtain systems are generally manufactured from stainless steel, wire reinforced, woven glass fibre fabric coated on each side with silver polyurethane.

Headbox

Headbox is manufactured from mild steel angle with an overall dimension of 42mm having a weight of 1.76Kg per linear metre. For curtains less than 2.3m wide a 4.3Kg per linear metre bottom bar would be used to ensure correct deployment under gravity. The 'T' bar can be powder coated to any standard RAL finish.

General Upgrades
  • Split drop delay: An optional braking system is available to allow a two stage descent during gravity deployment.
  • Partial descent to a predetermined level to permit preliminary escape and initial smoke containment, after delay the barrier descends to full operational position.
  • Voice warning: Audio or spoken multi message facility.
  • Beam protection and obstruction warning: A beam detector, with delay timer which will sound in the event of any obstruction being placed in the barrier drop line.
  • Visual alert system: Standard localized light or strobe light.
  • Emergency retract: Hold on retract facility for multi escape and emergency service access.
  • Walk through escape: Passage through the barrier.
  • Maintenance

    Maintenance and testing of the product

    There is a requirement under The Regulatory Reform (Fire Safety) Order 2005 for the building's responsible person to ensure all fire safety equipment is maintained.

    The period between checks is at the discretion of the customer however we recommend the following:

    Weekly Check all the system for correct operation. Test operation of systems, self contained detectors and check the integrity of the curtain.
    3 – 6 months Inspection and test of the system by a competent engineer.
    Annually Full inspection and test of the system by a competent engineer.
