Specifications :- Flameshield 120 & 240 Fire Shutter Doors

Flameshield 120 Commercial Shutter Door

Release Mechanisms:
Fire relay and key switch (requires maintained supply, battery back up needed if no maintained supply). Fire relay, key switch and fusible link if no fire alarm.

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. A volt free signal is required from the fire alarm.

Fusible Link Release:
On activation, the link which is a soldered link, separates and releases at 64 degrees centigrade, in effect the temperature release of the link creates a signal to the relay which in turn powers the door down.

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. 230mm wide x 240mm long x 120mm deep.

Size Parameters:
The shutter test relates to the 1HR/2HR fire resistance. The shutters are generally intended for protection of a range of openings in masonry / concrete, steel, steel stud or timber partitions. The maximum clear openings are for 4000mm wide x 2500mm high, or in a partition system for 1 hour up to an area of 10sq mtrs, principally this incorporates the BRE test FG 7941N which relates to a tested fire shutter in a stud partition, the opening must be fire rated to suit and be capable of carrying the weight of the shutter.

Where the shutters are used to protect serveries it is assumed that the counter is composed of non-combustible material and the counter is of sufficient width to ensure that the bottom rail movement under heating cannot result in the rail overhanging the counter. Shutters over 3500mm up to 4800mm will be traditional curved 75mm lath construction, based on a maximum area of 10sq mtrs. Shutters under 4000mm clear width will have 50mm guides and shutters over this width will have the traditional 65mm guides.

Battery Back Up Unit:
Principally the tube motor fire shutter requires a maintained supply. If this cannot be achieved then effectively the shutter will require a battery back up unit. If under fire conditions there is a power failure, the shutter must have a means of ensuring closure, the unit provided will give the facility for at least one operation under fire conditions. The dimensions of the battery backup are 200mm (wide) x 130mm (long) x 70mm (deep)

Paint Finish Option:
To compliment the aesthetics of your application, this product can be power coated to any BS or RAL colour (subject to availability)

Flameshield 240 Industrial Fire Shutter Door:

This fire shutter is designed to provide a heavy duty solution for industry and is a popular option for a wide range of industrial applications.

Release Mechanisms:
Fire relay and key switch (requires maintained supply, battery back up needed if no maintained supply). Fire relay, key switch and fusible link if no fire alarm.

Operation:
Self coiling, Chain operated (through a gear manual unit), Electrically operated 1PH / 3PH.

Electrical Operation:
All electric fire shutters are available in 3 phase, 415volts, 50hz or 1 phase, 240 volts, 50hz. The shutters are driven by a geared electric motor, which has an integral controlled descent mechanism, emergency hand chain facility and push button starter. The shutter rate of descent is controlled through the gears being constantly engaged, the closure speed is approximately 100mm per second. The clutch can be reset and the door can be raised and lowered in a normal manner. Each motor incorporates a relay inhibitor to prevent the solenoid "burning out" Activation is generally by means of a fusible link, solenoid release or both. Units available in 1 phase or 3 phase. The motor unit has the facility to simulate a fire test via a pull and reset cord.

Self Coiling Operation:
All manual fire shutters are designed that the door should be left in the open position and close only under fire conditions. The self coiling manual fire shutter is under sprung so that it closes in the event of a fire. The self coiling shutters have secondary guide channels to govern a drop bar: this falls under its own weight once the fusible link has been activated.

Maximum overall shutter size 2850mm wide x 3000mm high:
This manual fire shutter is designed to be left in the open position and close under fire conditions. Frequent use is not recommended, the shutters are under sprung to enable the door to close quickly under fire conditions.

Activation of this door is by means of fusible link only, this is a soldered link designed to melt at 68 degrees centigrade, this releases the drop bar and closes the door under its own weight.
Modes of Activation

Fusible link Release:
On activation, the link which is soldered link separates and releases at 68 degrees centigrade, on the manual shutter this will release the drop bar and the shutter will close under its own weight, on the electric shutters the manual brake release is activated and the shutter will close under a controlled manner.

Manual Solenoid Release:
All solenoid release mechanisms are designed to be linked into the fire alarm, the signal required from the fire alarm is 24 volt D.C. 0.5 amps on activation. The signal from the fire alarm will trigger the manual brake release and allow the door to close under a controlled descent.

Auto Solenoid Release:
Again. this is linked to the fire alarm and the signal required from the fire alarm is 24 volt D.C. 0.5 amps. This is the most commonly used activation allowing for frequent testing and re-setting, when the door is returned to the open position (after removal of the fire signal), the solenoid can be automatically reset.

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 into the solenoid. 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 solenoid to close the door.
