250 mA Door release power supply

Combined Magnetic
Door Retainer / Closer

Features Supplied on a compact double gang plate, the BF375P provides a continuous output of 24V 250mA dc and is ideal for locating alongside single or double doors which require door retaining magnets. Three trigger methods are available, (a) trigger and (b) hold off (both of which require a signal voltage of 5-27V dc 10mA) and (c) manual button release. Once triggered, the PSU's 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 purpose.

2A UNREGULATED DOOR RELEASE PSU

Features The BF377 is designed to provide continuous d.c.power for a 24V door release magnet system controllable from a fire alarm control panel. For automatic release, the power supply requires a signal voltage of 18-30V dc. 30mA. Manual release can also be achieved via a set of contacts using, for example via an external timer, in order to shut the doors automatically at a predetermined time. The BF377 does not have a battery back-up facility.
