Hart fire-resistant shutters, rated from 30 minutes to 240 minutes fire resistance, are manufactured to high standard specifications, building regulations and insurance requirements. They can be integrated into existing fire and security alarm systems, protecting people, products and your premises during a fire outbreak.
United laboratories of Chicago have tested, assessed, certified and monitor our range of shutters to UL10b/NFPA80 with standard sizes up to 7.3m (24ft) width or height. ISO 9001 certification ensures production and installation are completed to all relevant standards including health and safety during manufacture and installation. A controlled labelling procedure ensures product identity, trace-ability and compliance.

Geared electric in line motor unit with limit switch override. Unit capable of brake release via fusible link or solenoid to provide safe controlled rate of door closure under gravity.
30 minute, 60 minute, 120 minute and 240 minute
Door Dimensions: max 7.3m (24ft). All doors are made to measure to specific requirements. Larger sizes available as special design.
Constructed from single skin, 75mm convex interlocking galvanised roller shutter lath section. This section is available in three thicknesses 18G, 20G and 22G dependant on size and fire resistance requirement.
Pedestrian safety takes precedence when pedestrians commonly use the door. Audio-visual alarms coupled with delayed operation and or pedestrian photocells can be fitted. Safety brakes are fitted to all electric unsprung pedestrian fire roller shutters to prevent uncontrolled closure in the event of mechanical failure.
These heavy brackets designed to support the casing and roller in a fire situation are required on doors over 4.115 meters or 13.5 feet wide.
Power supply: Single phase or three phase as specified on the quotation.
Normal operation: Electric systems provide ease of use with press button operation or, should the door be used for security or general purposes, a key operated option to prevent unauthorised use. For safety reasons the position that the door is operated from must be able to enjoy a full view of the entire door. ‘Constant pressure must be maintained on the button by the operator’ until the door is fully closed. Additional safety must be provided for pedestrians if this is not the case.
Fire shutters activated by a sacrificial fusible link will operate the door independently when the heat around the link reaches approximately 75°C (other temperatures available). Alternatively most frequently, a fire roller shutter will be part of an overall fire (and smoke) control system. The electrically operated fire roller shutter system’s solenoid when initiated by a 24 volt DC 3amp supply, provided by the fire control system, will immediately commence the shutter to close at a controlled rate until it is fully closed. In the event of a fire test or false alarm the main fire control panel when reset, will allow the optional manual or auto re-set of the fire shutter to engage & return the system to normal operation after pressing the reset button. Various degrees of improving sophistication are available on request.
