24V 250mA Door Release Power Supply Unit

The BF375P power supply unit (PSU) from C-TEC is suitable for powering 24V DC door release magnets directly via a Mains derived power source. The non-EN54 approved PSU is IP40 rated for indoor use and has a maximum output of 250mA, meaning it can supply power for up to 5 door release magnets rated at 50mA each.

The 24V 250mA PSU enables you to keep doors open for access under normal circumstances, so promoting ventilation while ensuring they automatically close at pre-set times or after the initial fire alarm is activated. This works to keep exit ways clear of flame and smoke during emergencies, so reducing the risk to life and damage to property.

The BF375P door release PSU also features a robust PVC casing, light grey label, manual release button – which allows you to test your system whenever desired – and Mains On and Output Triggered LED indicators so you can monitor the system’s condition.

Plus, Trigger Release, Hold Off, and Local Trigger Inputs facilitate straightforward connection of the PSU to fire alarm control panels, timers, relays, building management systems, and related auxiliary equipment.

The compact 24V 250mA PSU from C-TEC can be mounted on a standard 25mm UK double gang flush or surface back box, making it perfect for retrofit applications.
