Single Fire Curtains

FC120 - FIRE RESISTANT CURTAIN

The FC120 is an electrically operated automatic vertical fire barrier, consisting of a stainless steel wire reinforced glass fabric curtain and galvanised steel box assembly and guide rails. The box, guide rails and bottom rail can be powder coated as an optional extra.

The curtain is powered by a 24v DC motor which includes gravity failsafe as standard.

This curtain is designed to remain open during normal use and only to be closed during a test or an emergency situation. In the event of receiving a fire alarm signal or a power failure the barrier will perform a controlled descent to create a fire resistant barrier.

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.

Maintenance

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

Maintenance and testing of the product

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, clean self contained detectors. Replace the two 12v lead acid batteries in the control panel*.

 

*The control panel incorporates two 12v lead acid batteries which are maintenance free. However it is recommended that the battery condition is monitored on a regular basis and that they are exchanged as necessary and at least every 12 months.

Professional Installation - FIRAS

The installation of a fire door or shutter is a complex procedure requiring a detailed understanding of the role played by each individual component. It therefore needs to be installed by someone with the correct training and expertise.

As approved Firas Registered Fire doors and shutter installers we ensure a certified and traceable process from manufacture to installation.

Why have your door and shutter systems maintained?

  • It is a legal requirement - as failure to show evidence of maintenance could mean prohibition & enforcement notices being served and fines up to £5000 and imprisonment for 2 years. 'Safety In Use', the New European CEN Standards legislation - States that all types of door should be maintained in an efficient state, in efficient working order and in good repair. For further clarification visit www.dhfonline.org.uk.
  • Routine maintenance prolongs the operational life of the installation and ensures that the installation is kept in good working order.
  • It ensures that the door is working in a safe and efficient condition - helping to prevent accidents and damage which in turn results in down time, effecting work flow, productivity and resulting in loss of revenue.
  • It assists in identifying potential problems which can easily be rectified.

 

Why Choose Automatic Curtains?


Smoke is the greatest threat to life safety in a fire situation, graphics 1 and 2 indicate one of the many problems smoke can cause in large buildings. In the event of a fire at a lower level, smoke will rise and enter the upper floors. This smoke will reduce visibility and cause occupants to be disorientated, and could result in deaths. By using Smoke Curtains with Smoke Ventilators and fresh air intake it is possible to ensure that the unaffected floors are protected.

Why Choose Automatic Curtains?



This graphic shows the result of installing an automatic smoke control system. The smoke detections system would activate and the Smoke Curtain system would be deployed on all floors with the exception of the floor on which the fire has been detected. In turn the smoke extraction system would operate. Smoke is restricted to the fire floor leaving the remainder of the building free from smoke allowing safe egress for the occupants.

Why Choose Automatic Curtains?

Fire compartmentation is a requirement of Building Regulations, access routes through fire compartment walls need to be protected to provide the required fire integrity. A cost effective solution is to install Automatic Fire Curtains which are a lightweight compact and convenient alternative to fire shutters.

This image shows an access door between 2 areas in a storage warehouse, the doorway is in constant use from pallet trucks and employees, however the doorsinstalled would not provide an adequate fire barrier.

Upon activation of the fire alarm system the fire curtain would descend and a compartment with a fire rating of 4 hours would be created. Fire curtains can be manufactured to various widths using single or multiple roller systems.

Product performance

Complete product tested to BS476: Part 20/22, and achieved a rating of DA (1000°C, above 60 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.

General Description

The automatic fire curtain consists of a X32K woven glass fibre fabric. The fabric is tested to withstand temperatures of up to 1000°C for a period of 60 minutes minimum, this is wound onto a steel tube, each of which will incorporate a 24volt d.c. motor, a sealed heavy duty ball bearing assembly, and an electronic control circuit. The automatic roller assembly, incorporating the fabric, is housed in galvanised mild-steel head box which is normally bolted to the fabric of the building. Standard head box sizes are 180mm x 180mm. Larger head boxes may be required where the curtain drop is in excess of three metres.

The lower edge of the curtains incorporates a twin inverted mild steel angle which acts as a weight bar to enable the curtain to unwind upon receipt of a signal from the fire alarm panel or total mains and battery failure. Metal side guides with a fabric retaining system shall be installed to provide a seal between the curtain fabric and the building construction.

Minimum width: 800mm Minimum height: 800mm Maximum width: 5200* Maximum height: 5000

*Larger widths are possible, prices available on request.

Control System

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.

The roller motors, which are 24 volt d.c., must be wired from the G.C.P. in a ring main using suitably sized cable to ensure a voltage of 24v d.c -10%. The curtains automatically descend upon receipt of a signal from the fire-alarm panel and automatically retract when the signal is removed. During ascent the motors are controlled via a synchronised speed circuit to ensure all curtains are raised at similar rates. The curtains descend under the power of gravity at all times, including total mains and battery back up failure.

Limit switches are not to be used to control the upper and lower positions of the curtain.

Optional extras:

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.
