Fire Rated Shutters Construction:
Manufactured from 77 mm curved galvanised steel lath 20swg.
Galvanised steel T-section bottom rail.
Galvanised 75mm X 25mm X 3mm mild steel guides.
Constructed to Exova Warrington Fire test certificate standard BSEN 1634-1.
Hood/canopy support brackets may be required, depending on fire rating, size and weight.
Fire Rated Shutters Operation:
Electrically operated external chain drive motor available in 3 phase, 415 volts, 50Hz, or 1 phase, 240 volts, 50Hz.
The motor is designed to de-clutch, allowing the shutter to gravity close in a fire situation at a controlled speed (option to power down).
Complete with emergency hand chain facility and rocker or key switch supplied as standard.
Release Mechanisms:
Generally by auto solenoid release, linked to the fire alarm. The solenoid requires a 24 Volt DC, 0.55 Amps signal. This is the most commonly used method of activation, allowing for frequent testing and re-setting. When the shutter is returned to the open position (after removal of the fire signal), the solenoid can be automatically reset. A fusible link or localised smoke/heat detector (see back page for details) can be used as back-up to activate the shutter, or as an alternative if no fire alarm signal is available.
Obviously a fire alarm cannot activated to close or cover a fire exit area.
Finish:
Galvanised self colour finish with one coat of primer paint on end plates, angles and barrel; can be polyester powder coated to any RAL or standard BS4800 colour.
