24V 250mA Door Release Power Supply Unit

With a maximum output of 250mA, this compact Mains-derived PSU can deliver power for up to 5 electromagnetic door retainers rated at 50mA each.

The 24V 250mA PSU works to keep access doors open, so promoting necessary ventilation while ensuring they automatically shut after the initial fire alarm is activated or at pre-set times. As a result, emergency exits remain clear of smoke and flames, so limiting the risk to life and damage to property.

The non-EN54 approved PSU is IP40 rated for indoor use and has a robust PVC casing with a light grey label. Additionally, it features a manual release button – that enables you to test your system regularly – as well as Mains On and Output Triggered LED indicators that allow you to monitor the system’s status.

Plus, Trigger Release, Hold Off, and Local Trigger Inputs facilitate easy connection of the PSU to fire alarm control panels, building management systems, timers, relays, and related auxiliary devices. The 24V 250mA door release PSU from C-TEC can be flush or surface mounted on a standard 25mm UK double gang back box, making it compatible with retrofit applications.
