قفل Vimpex|Universal
The Vimpex EN 1155 approved Universal door holders are rugged and versatile and can be used for many different door holding applications. They can be either floor or wall mounted. Available in two standard lengths - 200 or 300 mm, there is also a choice of two holding forces - 500 or 1000N. Mounted onto a fixed surface, these door holders ensure retention of the fire door by means of a smart metallic keeper plate. Interfaced with the fire alarm system, the door holders 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.
