Magnetic Door Release - Magnetic Door Opener

The unit is designed for use with automatic fire alarm systems in buildings where doors are normally required to be left open. When the system is in alarm, power is removed and the door is released. The door must be fitted with a self closing mechanism so that it closes automatically. The unique spring release design of this unit provides a holding force of 40kg without associated problems of residual magnetism, thus ensuring a quick release of the door required. Each consists of two parts - a door plate, which is fitted to the fire door and a solenoid unit which is normally positioned on an adjacent wall. A floor mounting bracket is available for use if wall mounting of the solenoid unit is not convenient. The solenoid is controlled by the fire alarm system so that it is continuously energised, thus magnetically attracting the door plate and holding the door open. A relay may be required to interface the door release unit with the fire alarm control panel.
A manual release button, that can be fitted to either side of the solenoid, is provided to enable doors to be closed without operating the fire alarm system.
