✅C-Tec 24V 3A EN54-4 Switch Mode PSU (BF562-3)
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.
✅Key Features
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).
✅Specifications
Approvals/certifications
Certified to EN54-4/A2 by the LPCB & VdS.
Application/operation
A boxed Mains to regulated DC power supply providing 3A @ 24V DC. Fully compliant with EN54-4, it includes a single pole volt-free changeover relay that switches for any fault condition.
Mains supply
230V 50/60Hz.
Mains rated current
0.8A r.m.s.
