VDS certified to EN54-4 (1997/A2:2006). Ideal for powering beam detectors, auto-dial communicators, aspirating smoke detectors, auto-open vent systems, auxiliary sounder systems or any other device performing a mandatory function of a fire alarm system. Deep discharge battery protection and EN54 compliant reporting of battery impedance faults. Includes a single-pole volt-free changeover relay that switches for any fault condition. Three LED indicators - supply present, general fault and auxiliary fault (for optional connection to third-party equipment). Link selectable battery charging capacity. Environmentally-friendly charging circuit - dissipates just 0.35W compared to the industry norm of 2.55W. Supplied in a tough, durable metal box. Optional 'caged' and 'PCB-only' versions available with exactly the same electronics (order code BF362-3/E and BF362-3/C respectively).

Key Features; A powerful switch mode/digital hybrid PSU that can be customised to suit your exact requirements. Plastic cover on PSU PCB guards against touching live parts (to VDE 0100-410). Includes the same electronics as our BF560-24 LPCB certified EN54-4/A2 boxed 24V 1.5A PSU. Metal base plate facilitates straightforward mounting inside third-party OEM enclosures. Includes a single-pole volt-free changeover relay that switches for any fault condition. Includes a fault type & hazardous voltages present LED. Two selectable battery charge currents. Battery fault impedance limits can be optimised to suit load current (helps extend battery life). Mains fail simulation mode. Improved on-board temperature sensor with optional remote sensor. Electronic functions comply with EN50131-6 grades 1-4 for security applications. Optional PCB-only version (without a metal base plate) available.

Comprises 2 x 12V rechargeable batteries and a link wire. Each battery measures 97 W x 50 H x 43 D mm. Quick connect 4.75mm 'Faston' type terminals.
