Fire performance
• Tested to BS EN 1634-1 specifically for servery hatch applications
• Fire integrity: E60 (up to 8.0 m wide x 2.4 m high), or E120 on openings up to 2000 mm x 2000 mm
• Integrity (E) applies whichever side of the shutter the fire is on
• No radiation (EW) rating is available on rigid structures
• The classification applies only to the tested shutter and supporting construction
• Only servery-tested shutters can be used for servery openings. Doorway shutters must not be used
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
• 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, counter or cill, power supply and fire alarm interface are provided by others
Counter, cill and floor
• The counter or cill the shutter closes onto must be non-combustible, Class A1 to EN 13501-1
• The floor must be non-combustible, with a minimum Class A2 classification to EN 13501-1
Curtain and guides
• 75 mm curved galvanised steel slats
• Steel U-section guide rails, sized to suit the fire rating, motor type and opening
• Controlled descent when closing
Tubular motor (smaller openings)
• The maximum opening size depends on the weight of the curtain the motor can lift
• Motor fitted inside the barrel
• Closes automatically on a fire alarm signal, or on a heat detector with the FCP03 panel
• Standard battery backup (about 4 hours) powers the shutter down if the power fails during a fire alarm activation
• Optional deluxe sleep-mode battery backup lasts about 30 days and is woken by the fire alarm
• Manual override
Industrial motor (larger openings)
• Up to 8.0 m wide x 2.4 m high at E60
• 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)
Escape routes
On an escape route, the shutter must be triggered by a heat detector or fusible link only (Approved Document B, 2019 edition).
The final specification should reflect the required fire classification, opening size, supporting structure, motor and fire control strategy.
