BF375PE Door Retaining Controller, 24V DC Output on 2 Gang

This power supply unit is capable of supplying door retaining magnets at a nominal 24Volts with a maximum output load of 250mA. When used with smoke/heat detectors an automatic door release system can be built.
250mA 24v D.C. Output on 2 Gang Plate with Door Retainer Release Switch.
The BF375P is a Mains derived power supply unit designed to provide power to 24V DC electromagnetic door retainers. It has a maximum output of 250mA. A variety of inputs are provided for connection to all types of fire alarm control panel, building management systems, timers, relays and other ancillary equipment. When the correct stimulus is applied to one or more of the inputs, power to the retainer(s) is removed, causing the door(s) to close. Supplied on a compact double gang plate, the BF375P provides a continuous output of 24V 250mA d.c. and is ideal for locating alongside doors which require door retaining magnets. Three trigger methods are available, trigger and hold off (both of which require a signal voltage of 5-27V d.c. 10mA) and manual button release. Once triggered, the PSUs output voltage is removed causing any door release magnets connected to it to de-energise. The BF375P is designed specifically for use as a door release PSU and is not suitable for battery charging or any other use. It is also available as part of the BF375PK door retainer and PSU kit.
