Fire Shutter - Fireroll Acoustic

Bolton Gate Company’s Fireroll range of roller shutters is the most comprehensive available in the market.  A further  addition is the Fireroll Acoustic E120 which combines fire resistance with a high degree of sound reduction.

During extensive testing at Salford University Department of Acoustics and two Fire Test Laboratories, the door achieved a sound reduction of a maximum 25.2dB (at 2000Hz) with a 22dB Rw coupled with a rating of E120 when tested in accordance with EN1634-1.

In keeping with the same testing, the shutter is also rated EW90 or EW120 dependent on size for face fixed arrangements.

A special double curtain arrangement is also available which reduces sound transmission further to a maximum of 39.1dB (at 2000Hz) with a 32dB Rw.

Operation

All shutters are electrically operated by a 230-volt nominal single phase or 400-volt nominal three phase Speedsafe motor mounted on one endplate and have adjustable limit switches incorporated to stop the shutter at the end of each travel.  A pull cord and hand chain are provided for use in the event of power failure.

Standard operation is via a low-level push button station with emergency stop button.

In a fire condition, gravity failsafe closing is activated by a 24-volt DC signal (0.37 amps) from the client’s fire alarm panel to the auto reset solenoid which releases the motor brake and is backed up by a fusible link.

A safety brake is supplied to comply with the safeguarding requirements of EN 12604.

Curtain

Shutter curtains are constructed from 100mm high flat section continuously interlocked galvanised steel laths which are securely held in place by steel end locks. Each lath is infilled with fire resisting acoustic material.

Bottom Rail

The bottom rail comprises a standard lath fitted with a galvanised steel trim section.

Side Guides

Vertical guides are formed from galvanised steel double rebate channels and are supplied with suitable profiles for fixing to the structure.

Roller

The roller is constructed from seamless steel tube of adequate diameter to resist deflection and held in bearings or cups attached to the endplates

Endplates

Zinc plated mild steel of appropriate thickness relative to door size and supplied with angles for fixing to the structure.

Coil Casing

A galvanised steel coil casing is supplied to maintain the fire seal at the head.

Finish

Fireroll Acoustic E120 is supplied with most parts galvanised as standard. Where non-galvanised parts are utilised, these are finished with one coat of primer paint
