The curtain runs in vertical steel channel guides fixed to each side of the opening, with end stops fitted at the top.

Standards
Shutters meet the requirements of EN 13241-1: 2003 and are CE marked.

Shoot bolts can be fitted on the inside for
additional security.

Chain-operated shutters can be secured by a chain keep which can also be padlocked. Pass door is normally fitted with a Yale-type lock; other locks can be supplied to order.

Finish

Alternative finishes: Powdercoated to any BS or RAL colour to one or both sides. Plastisol to one side only with Powdercoat on other.

Sizes

Options
Pass door.
Perforated laths.
For exposed situations, strengthened guides and/or wind endlocks may be fitted.
Steel casing to fully enclose the roller and motor. This is a requirement on all fire-resisting shutters (excluding the motor), and is recommended on others to protect the lath hinges from dirt and grit.


Operation
Manual push-up, for shutters up to about 2.5m high.
Higher shutters are normally operated by manual endless chain handwheel.
Manual and chain drive shutters are counterbalanced with helical torsion springs inside the barrel; adjustable tension is set at time of installation.
All shutters may be power-operated, especially large shutters or where automatic operation or safety interlocks with other equipment are
required.
There are three motor types dependant on
size and application:
Direct drive motor
Geared motor where sideroom is limited and Tube motor for less industrial applications.

Direct drive motors have built-in safety bearings. Geared and Tube motors have safety bearings incorporated in the non-motor side of the barrel.

Safety
Safety edge and photocell door protection
systems are optional on powered shutters.

Controls
Various automatic or remote control systems
are available for powered shutters.
