Fireguard Fire Resisting Roller Shutter Doors

Certified fire rated roller shutters - Rated from 1 to 4 hours

Fire shutters from HVP are designed to automatically close in the event of a fire. They seal off the opening they sit over and prevent the spread of fire. Our fire shutters have a rating of 1 to 4 hours.

Fireguard fire resisting roller shutters are thoroughly tested and conform to strict standards (see the technical specification for more information).

The main purpose of a fire shutter is to prevent or slow down the spread of fire. In addition, it can also be used as a security shutter. Fire-shutters from HVP have a solid lath and are similar in appearance to our Screenguard security roller shutters.

Fireguard fire-shutter technical specification

HVP's Fireguard fire shutters are available in two versions:

  • Fireguard FS75 - Traditional Fire Shutter (for larger openings) with the motor fitted externally.
  • Fireguard FS50 - Tubular Motor Fire Shutter (smaller head plate size) with the motor fitted within the barrel.

Technical Specification Fireguard FS75 fire shutter

A block motor fire-resisting roller shutter

Construction:

Manufactured from 75mm curved galvanised steel lath. Galvanised steel T-section bottom rail; Galvanised mild steel guides 65mm u-section. Hood support bracket may be required, depending on fire rating, size, and weight (check with HVP).

Operation:

Electric operation external block motor available in 3 phase, 415 Volts, 50Hz, or 1 phase, 240 Volts, 50Hz. The shutter is driven by a geared electric motor, allowing the shutter to gravity close in a fire situation (rate of descent approximately 100mm per second). Complete with emergency hand chain facility and push button starter.

Release Mechanisms:

Generally by auto solenoid release, linked to the fire alarm. The solenoid requires a 24 Volt DC, 0.5 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. An optional fusible link or localised smoke/heat detector can be used as a backup to activate the shutter or as an alternative when a fire alarm signal is not available.

Finish:

Galvanised self-colour finish with one coat primer paint on end plates, angles and barrel; can be polyester powder coated to any RAL colour (subject to availability).

Size Guide:

Maximum Size: 8000mmW x 6000mmH

Technical Specification Fireguard FS50 fire shutter

A tubular motor fire-resisting roller shutter

Construction:

Manufactured from 50mm flat (up to *4000mmW) or 75mm curved (up to *4800mmW) galvanised steel lath. Galvanised steel T-section bottom rail. Galvanised mild steel guides, 50mm u-section up to 4000mmW or 65mm u-section up to 4800mmW.

*Note: the maximum width will reduce according to the height.

Operation:

Electric operation by single phase tubular motor. A safety brake fitted when required to comply with BS EN 13241:2003-1.

Release Mechanisms:

Generally linked to the fire alarm through a fire relay. Upon receipt of a Volt-free signal from the fire alarm, the shutter is powered down. The shutter requires a maintained power supply, and is supplied with a battery backup in case of mains power failure. A fusible link or localised smoke/heat detector can be used as a backup to activate the shutter or as an alternative when a fire alarm signal is not available.

Finish:

Galvanised self-colour finish with one coat primer paint on end plates, angles and barrel; can be polyester powder coated to any RAL colour (subject to availability).

Size Guide:

  • Minimum width: 800mmW overall endplates
  • Maximum Sizes: Up to 4800mmW and up to 3850mmH
  • Maximum overall area: 10 square metres. For larger areas use the FS75 fire shutter.

Technical description Fireguard roller shutter

It's very important that fire resisting roller shutters are fitted correctly. A properly installed fire shutter will perform as specified. A fire shutter that is installed wrongly might not hold back a fire.

All of HVP's installers are are specially trained to install fire shutters in the right way.

The fire shutter shown in the pictures above is installed in an industrial warehouse where the fire shutter creates a fire break between two separate storage areas.

Finishes

The fire shutter shown has a galvanised finish. All fire shutters can be fully powder coated to any RAL or BS colour.

Fireshutter modes of activation

Fire shutters are often held in the open position. They are fitted with a push button control station as standard.

A fire shutter can have more than one mode of activation in the event of a fire. They are most commonly linked into the building's fire detection system but can also be fitted with a soldered fusible link. When activated by the building's fire detection system, the shutter will close at an approximate speed of 100mm per second.

When the fire shutter is fitted with a soldered fusible link mechanism, this is generally located on the shutter hood. The solder in the link melts at around 68 degrees centigrade, which releases a cable and the shutter will close. The fusible link can act as a back-up mechanism, but in some situations a fusible link is the only means of activation. A Building Control Officer or Fire Officer should advise on this.

Alternative backup systems are an electronic heat detector or a smoke detector.

Audiovisual warning panels (FDI)

If people are likely to be trapped by a closing shutter, then a Fire Detection Interface (FDI) panel is required. The FDI panel is an audio-visual warning panel. Upon receipt of the fire alarm signal it starts to flash and beep. It can be programmed in a variety of ways, e.g. a time period to delay closing of the shutter. In some situations a Repeater Panel will also be required. These are linked to the main FDI panel and simply copy what it does. A typical requirement would be where a panel is required on both sides of the opening.

Fireshutter certification and performance

Fire shutters are certified products. In practice, this means they must always be manufactured and installed to match their certified specification. To deviate from this specification renders the certification invalid. Essentially, this means the shutter might not perform as intended in a fire situation.

A fire shutter that has been built to its certified specification and has been installed correctly will form an effective fire barrier when closed.

Because metal expands when heated, fire shutters have oblong fixing holes. By using the correct fixing method a fire shutter is allowed to expand in a fire situation.

Security and fire resistance

The main purpose of a fire-resisting roller shutter is to prevent the spread of fire. Therefore, authorities often require fire shutters to be installed in public areas where there is a risk of fire. Good examples are canteens, serveries and commercial kitchens. Fire shutters are also often used to keep certain areas safe for people in the event of a fire; think of escape corridors in stadiums, shopping centres or office blocks.

Many fire resisting roller shutters perform a double function; as well as automatically closing in the event of a fire, they are used as everyday security shutters, very similar to our Screenguard roller shutter.
