DOOR RETAINERS
Arguably the single-most important fire safety mechanism, electromagnetic door retainers guard against the lethal spread of toxic smoke and fumes – by far the greatest cause of death in fires.
The Merrion Fire + Safety range of door retainers offers the installer the broadest choice of mounting styles, holding power and installation accessories.
Mounted onto a fixed surface, these door retainers ensure retention of the fire door by means of a smart metallic keeper plate. Interfaced with the fire alarm system, the door retainers are de-energised as soon as the fire is detected thus releasing the door without the potentially harmful delay suffered by other types of devices.
All Merrion Fire + Safety door retainers feature metal enclosures to guard against heat fatigue – a problem associated with lower quality, plastic enclosures. Each magnet has an individually calibrated ejector pin which ensures that residual magnetism does not affect performance.
