Designed to stop the spread of not only fire but also smoke, fire doors are an important part of the fire strategy/engineering of any building. During normal operation these doors are often required to be held in the open position for access and convenience.
We supply several types:
Door Magnet
A door magnet normally holds the door in an open position to a wall. The door will have a separate closer fitted to close the door when the electrical supply to the magnet is removed.
Automatic Door Closer
Hold open closer: A device that once energised will hold the door in a fixed open position. When the electrical supply to the closer is removed, the closer will close the door as normal.
Free swing closer: A device that once energised will hold the door open but the door becomes weightless enabling it to be used as a normal door. When the electrical supply to the closer is removed, the door will be closed from any position by the closer.
Door Release Unit
A door release unit mechanically releases an electrically operated door in the event of a fire alarm – for example an automatic entrance door or secure door fitted with access control.
