It suits installers linking a few held-open doors to a fire alarm panel or building management system. It gives 250mA, enough for up to 5 retainers rated at 50mA each.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePowers a small group of doors – up to 5 electromagnetic door retainers rated at 50mA each\u003c\/li\u003e\n\u003cli\u003eConnects to what is already there – inputs for fire alarm control panels, building management systems, timers and relays\u003c\/li\u003e\n\u003cli\u003eRelease by hand – a red manual release button on the fascia\u003c\/li\u003e\n\u003cli\u003eEasy to check – Mains On and Output Triggered indicators\u003c\/li\u003e\n\u003cli\u003eFits a standard box – mounts on a standard 25mm UK double gang flush or surface back box\u003c\/li\u003e\n\u003cli\u003eRuns from the mains – 230V 50\/60Hz, giving 250mA at 21-28V DC\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFor installers\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePower: mains supply 230V 50\/60Hz.
