Fire Shutters

GUARDIANS HEPHAESTUS FIRE SHUTTER - FM240 Fire resisting roller shutter doors are purposely designed for large openings.

The FIRE-FM240 is designed to give up to 240 minutes of fire protection, with a multitude of fixing options certified and available to satisfy the current fire regulations.

The shutters are constructed to Warrington Fire Research Centre WARRES No 145904, the test is in accordance with clause 8 of BS476 part 22:1987.

SPECIFICATION

CURTAIN - Constructed from 75mm wide curved interlocking galvanised steel lath with steel endlocks and galvanised T section bottom rail.

BARREL - Constructed from mild steel tube with Helically wound counter balance springs mounted on mild steel bright shaft, with mild steel bearing blocks at each end incorporating high speed bearings. Tube and shaft size are dependent upon shutter size.

ELECTRICAL OPERATION - By means of 1/2 - 2 H.P. geared motor complete with rotary limits and emergency hand mechanism. 3 push button control as standard.

ELECTRICAL SUPPLY - 240Volt 1 phase, or 415 Volt 3 phase (additional information available on request).

SIDE GUIDES - Constructed from 3mm x 63mm galvanised channel for both drop bar and curtain. Bolted to a continuous 75mm x 50mm mild steel angle.

COIL CASING - To suit end plate dependent upon size from galvanised 0.9mm sheet. Slotted for expansion to suit M10 fixings.

FINISH OPTIONS - As standard galvanised curtains, side guides and coil casing, with black painted angles and end plates. However, to compliment the aesthetics of buildings, this product can be powder coated to any BS or Ral colour.

MODES OF ACTIVATION

FIRE RELAY - Principally the commonly used means of release, the characteristics mimic the use of the solenoid on the conventional fire shutter, again linked to the fire alarm, the shutter rather than closing manually through the gearbox will of course be powered down.The unit will require a maintained supply; if this is not possible a separate battery back up unit can be provided.

FUSEIBLE LINK RELEASE - On activation the link, which is a soldered link, separates and releases at 68 degrees centigrade, in effect the temperature release of the link creates a signal to the relay which in turn powers the door down.

Again if there is no facility for a maintained supply the battery back up unit must be used.

AUDIO VISUAL WARNING (FDI) Principally this unit is designed to delay the closing of the fire shutter; generally the fire alarm is linked to the audio visual unit and from the audio visual unit straight into the key switch. There is no need for a separate relay; there is already a relay in the FDI.

On activation from the fire alarm the unit starts to “flash & sound”, this unit contains a programmable timer which effectively delays the signal to the relay in the panel to close the door.
