Power Supply Unit 24V 250mA Door Release

The door release power supply unit is designed to provide power to electromagnetic door retainers from a Mains derived power supply unit. This allows you to keep fire doors open for ventilation and access whilst ensuring they automatically close when the first alarm activates or at pre-set times. As a result, emergency exits are kept clear of fire and smoke to reduce risk to life and damage to property.

With trigger release, hold off, and local trigger inputs, the BF375P door release PSU, manufactured by C-TEC, is easy to connect to fire alarm control panels, building management systems, timers, relays and other ancillary equipment. Featuring a manual release button to ensure you can regularly test your system, LED indicators show the system health and status.

The plastic non-EN54 approved PSU can power up to five electromagnetic door retainers, is IP40 rated for indoor use and has a maximum output of 250mA. Suitable for flush or surface mounting onto a standard 25mm UK double gang back box, making it ideal for retrofit applications.
