Ratings by application
• Doorways, rigid structures: E60, E120 or E240 (E120 and E240 on smaller sizes). Up to about 10 m wide x 7 m high at E60. No EW20 rating
• Doorways, timber stud walls: E60 or E90. Up to 7 m wide x 7 m high. EW20 available up to 2400 mm x 2400 mm
• Serveries, rigid structures: E60 with the industrial motor, up to 8.0 m wide x 2.4 m high. No EW20 rating
• Serveries, timber stud walls: E60 with the industrial motor, up to 8.0 m wide x 2.4 m high. EW20 available up to 2500 mm x 1500 mm
• Integrity (E) applies whichever side the fire is on. EW20 applies only in the tested direction of fire exposure. This is an uninsulated shutter: an E rating provides integrity, not insulation (EI) or smoke control
• Doorway shutters must not be used for servery openings
Testing and certification
• Tested to BS EN 1634-1 and classified to BS EN 13501-2
• Doorways: extended application to BS EN 15269-10, and UKCA and CE marked to BS EN 16034
• Serveries: tested to BS EN 1634-1 specifically for servery hatch applications
• The classification applies only to the tested shutter and supporting construction
Supporting structure
• Masonry or concrete: normalised high-density rigid construction with an overall density of at least 850 kg/m³, and a thickness suitable for the required fire rating
• Protected structural steel: must satisfy Rule J.2.1 of BS EN 15269-10 and be designed with a specialist passive fire protection engineer, using a fire protection system tested to EN 13381-4 or EN 13381-8
• E60 only: protected mild steel box-section packers or goalpost frames are permitted where the section factor (A/V) is less than 230 m⁻¹ with four sides exposed, and the fire protection keeps the steel at 400 °C or less
• Timber stud walls must be built to the tested specification for the application. Full details are on our Doorway and Servery Fire Shutter – Flexible Structure pages
• The supporting structure must have an equal or greater fire resistance than the shutter
• Not suitable for: standard (non-fire-rated) plasterboard, insulated panel walls, metal stud partitions, plastic-lined walls, whitewall partitions (unless cut back to brick) or unprotected structural steel
• We supply the fire shutter and its controls. The supporting structure, floor, counter or cill, power supply and fire alarm interface are provided by others
Floor, counter and cill
• Doorways: close to finished floor level. The floor must be non-combustible, with a minimum Class A2 classification to EN 13501-1
• Serveries: the counter or cill the shutter closes onto must be non-combustible, Class A1 to EN 13501-1
Curtain and guides
• 75 mm curved galvanised steel slats
• Steel U-section guide rails, sized to suit the fire rating and opening
• Controlled descent when closing
Industrial motor
• Heavy-duty external chain-drive motor, single-phase or three-phase, included in the test reports
• Closes automatically on a fire alarm signal (via a solenoid release) or by fusible link
• Fusible link melts at 67 °C and closes the shutter under gravity, even with no power
• Chain override to raise and lower the shutter in a power cut
Control panels and warnings
• Standard FCP01 panel: 0–5 minute delay before closing and a 98 dB sounder
• Deluxe FCP03 panel: adds staged descent, an emergency escape function and heat detector wiring
• Interface with the building's fire alarm system (volt-free contact)
• We recommend an audio-visual warning device on both sides of the shutter. Check what the site's fire risk assessment requires
• Maximum two opening and closing cycles per day
Finish
• Galvanised as standard
• Powder coating in any BS or RAL colour (may add to cost and lead time)
Typical applications
• Large doorways in warehouses, factories and industrial buildings
• Loading and service openings between fire compartments
• Large servery and counter openings in commercial kitchens
Escape routes
On an escape route, the shutter must be triggered by a heat detector or fusible link only (Approved Document B, 2019 edition). It must not obstruct a required escape route unless its location, closing sequence, warnings, controls and alternative means of escape have been specifically designed and approved as part of the building's fire strategy.
