• BSEN 12978 Safety devices for power operated doors
• BSEN 12625 – requirements for the safe installation and use

Motor

Depending on door size the motor drive is constructed using either Safedrive direct drive or via chain drive and reduction gearing supported via a safety brake. Very large sizes may also have internal counterbalance springs to reduce operating loads and minimise the drive requirements.

ENGINEERING

Size

Doors are available from 1.2 metre wide to 9 metres wide and up to 9 metres high. All doors are made to measure to specific requirements. For a higher security rating or extreme wind conditions we recommend the SR4 Terror Screen doors or our unique Typhoon security shutter.

Curtain

Constructed from 85 x 25 double skin interlocking galvanised steel sections and retained at ends by a mix of nylon and steel wind end locks. The door curtain is made up from an insulated lath section giving a thermal insulation value of 0.69w/m.sq.k across the lath section and an acoustic value reduction of 18db across the lath section.

Locking

• Manually operated slip bolts on the bottom rail or pin locks on the guide, manually interlocked to the control panel to prevent accidental operation.
• Electrically operated by press button when the door is closed
• Fully automated.
• Optional Monitoring and signalling of lock status.

Bottom Rail

Fitted with a purpose-designed extrusion complete with interlocking (EPDM) rubber weatherseal.

Door Guides

Continuous steel angle bolted to the door jamb supporting an 88mm deep guide channel. The channel has nylon seals down internal edges of the guide mouth. Guides are pre-galvanized prior to rolling and can be optionally powder coated at extra cost to match the door colour. The channels are re-enforced with steel plates to allow the door channel to transfer the 4kpa wind loading from the door curtain back to the supporting structure.

End Plates

Circa 500mm square shutter steel end plate with steel angle fixing to door frame. The end plates support the weight of the shutter and are fixed through the angles to the supporting structure.

Roller

A steel tube adequate to prevent deflection of less than 400:1 along its length with welded steel supporting axles on self-aligning ball bearings, non counterbalanced i.e. no springs. The assembly will be primer painted with exception of the axles which will be wax coated.

Seal at Head

A brush seal can be provided as an option across the head of the door to close the opening from outside.

Hoods

Supplied as an option in 0.9mm pre-galvanised sheet steel, folded around the end plate assemblies to form a three sided enclosure and fixed directly to the door support frame through a flange provided along its top edge . The sections will be joined with a vertical joggle connection. The hood may be powder coated, at extra cost, to match the door colour.

Power Supply

The 3 phase, neutral and earth, 16amp 380/440V AC, 50hz power supply will terminate in a Euro 5 pin industrial socket within 1 meter of the door control panel on the motor side at approximately 1.5M above floor level. The press button controls will be mounted at approximately 1.2M above floor level. The wiring connections between the control panel and the motor will be in braided cable with plug and sockets arrangements to allow for easy site installation. The cable will then be surface clipped.

Drive System

The Safedrive unit has been specially developed for roller shutter doors which are non-spring counter balanced. The drive is provided by hollow shaft keyed drive through the door axle. It has been designed for a long service life and has a built in safety brake device which conforms to all current BSEN industrial and commercial safety standards. The unit also has a build in limit switch.

Manual Override

All doors are supplied as standard with a Ground Floor Hand Chain Operation with floor level engagement, or crank handle operation at the motor, for emergency operation. (Note: this is heavy and slow to operate)

Control Panel

The IP 65 enclosure incorporates open, close and stop buttons with the provision for installing a key switch and/or latching stop button if required. It houses a digital control system which allows for limit switch setting from ground level, has a programmable door maintenance indicator, load monitoring in the open direction, digital display of door status and/or fault diagnosis, and meets the requirements of BS EN 12453.

Normal Operation

Press buttons in full view of door. Impulse open and “hold to run” close. Options include key switch. To operate by momentary pressure in the closing direction, safety systems need to be included.

Safety

As standard, fitted with either an integral motor safety brake or an auxiliary safety brake, depending on motor choice. Optional optical safe edge on the bottom rail, photo cell protection, warning signs, and increased protection levels as required.

Operating Speed

The standard travel speed is circa 100-200mm/sec depending on door size and weight

Wind resistance

Resistance to EN 12424 Wind Class 5. Enhanced design to meet minimum pressure resistance of 4,000 Pa

Optional Automatic Operation

Full automatic operation via control panel by remote induction loop, radio control, with full safety systems. Finishes: Galvanised steel as standard with options for Plastisol or RAL powder coated finish or stainless steel to one or both sides of the curtain.

Finishes

Galvanised steel as standard with options for Plastisol or RAL powder coated finish or stainless steel to one or both sides of the curtain.
