High speed emergency roller doors from DMF International

High speed roll doors and fast action doors are becoming increasingly popular in a variety of industries for climate control, security, and quality control. It is important to recognise the application that these doors are used in, and what forms of egress exist in the case of emergency or power failure. It is especially important, if the high speed door is the only egress out of a room, and therefore consideration must be given as to the egress.

Depending on the model selected, DMF can provide options of methods to open these high speed doors during a power failure. This may include a brake release lever opening the door, or a zipper in the panel.

By far, the most effective form though, is with the provision of a battery backup (UPS). DMF can provide a system which is installed in line to the high speed door controller, which is trickle charged ensuring a fully charged battery pack. During a power failure, the UPS provides power to all functions of the door, including the activation and the safety sensors, and depending on the door size, will allow up to 10 cycles of operation. Normal activation of a door during a power failure or emergency situation, has obvious advantages given that users may be in a state of panic, and familiarity can help to ease this stress. An advantage of being able to also close the high speed door, is that the internal conditioned environment is maintained during this power failure.

DMF have been manufacturing Rapid Roll doors for over 20 years, and continue to develop a product that is well recognised in many industries.
