The FireSafe 60 is an electrically operated automatic Fire Barrier, to be used to form a continuous barrier against fire.  

Product Performance:

Complete product tested to BS 476: Part 22: 1987 Clause 8 and achieved a rating of 1000°C, above 60 minutes.

When tested to BS 476 Part 22: 1987 the FireSafe 60 product achieved Integrity performance of 60minutes.  

Classifications as detailed within EN 13501 – 2:2007 + A1: 2009 therefore detailed as E60 Integrity.  

Designed to operate for 2000 cycles at normal ambient temperatures in the range of 0°C to 60°C and to withstand hot air and smoke at temperatures up to 1000°C for over 240 minutes once only.

The LBS FireSafe 60 can be provided to protect openings widths of up to 7m and heights up to 6.6m.

General Description:

The curtain head box is manufactured from 1.2mm zintec steel, the enclosure is rated at the same temperature as the curtain fabric. Removable cover plates are incorporated to allow access to the curtain rollers.  Standard head box sizes are 160mm x 160mm larger head boxes may be required where the curtain drop is in excess of 3m. A suitably weighted bottom bar is provided to prevent deflection and ensure correct operation under gravity.

The roller is constructed from tube, each of which incorporates a 24volt D.C motor. The curtain fabric is made from filament glass fibre, treated with proprietary finish to enhance temperatures resistance. Both sides of the fabric is coated with a flame retardant silver grey aluminium filled polymer. The weight is approx. 450 g/m2 in its finished form. Fabric thickness is 0.4mm and the weave is 4 end satin and is tested to withstand temperatures of up to 1000°C for a period of 60minutes.

Side guide with a fabric retaining system shall be installed either side to provide a seal between the curtain fabric and the surroundings.

The FireSafe 60 curtain has fixing options to suit all types of ceiling configurations and can be integrated into either a suspended or a solid ceiling. It remains hidden until required. Upon receiving a signal from the fire detection system or on loss of power with the gravity fail safe system, the curtain automatically unwinds to its operational position

Control System:

The panel model number is FC– 01 GFS and is classified within the following EU Directives: Low Voltage Directive 2006/95/EC and Electromagnetic Compatibility Directive 2004/108/EC.

Under normal operating conditions the curtains would be held in the retracted position via the motors operating at low voltage. Upon activation of the fire alarm the control panel will remove the supply voltage and the curtain will descend under the power of gravity in a controlled manner. A dynamic braking system housed in the motor control circuit controls the speed of descent of the curtain, with a common bottom bar.

To retract the curtain the control panel supplies 24v to the motor and the motors drive the curtains to the upper position. As the bottom bar hits the curtain head box the limits setting holds the bottom bar in the retracted position.

Should the mains power fail to the group control panel the supply is automatically switched to the integral standby battery. The curtain remains in the retracted position for 24hrs. The curtain will remain fully operational until the battery low voltage cut off facility reads a voltage of 21v, the curtains will then safely descend under the power of gravity to the operational position.

Optional Extra’s

Split Drop:

An optional braking system is available to allow a 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.

Delay on Alarm:

The system control can be programmed to allow a time delay on the alarm for a number of minutes before the barrier descend to its fire operational position.

Beam Sensor

A beam sensor by itself can be used as either a block sensor or an override; when the fire alarm goes off and someone passes through the curtain the beam sensor can be wired to either stop the curtain in its tracks or to retract the curtain. Please note that when used in isolation the beam sensor does not trigger a sound.

Emergency Over Ride Switches:

Hold on retract facility for escape and emergency service access.

Visual Alert System:

Flashing light and sirens are connected to the control panel and provide a warning when the curtain is about to descend. When the fire alarm is triggered and the fire curtain deploys the beacon will flash and a sounder alert until the signal from the alarm is lost. Please note that when used in isolation the audio visual unit does not stop the fire curtain descending or retract the curtain.
