C-TEC 5 Series 24V 3A EN54-4 Metal Boxed PSU (2 x 12V 18Ah Max) (BF562-3)

The C-TEC BF562-3 is a 24V 3A switch mode/digital hybrid power supply in a metal enclosure, certified to EN54-4/A2 by the LPCB and VdS. It is 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

• Certified to EN54-4/A2 by the LPCB and VdS
• Single-pole volt-free changeover relay that switches on any fault condition
• Supply present, general fault, fault type and auxiliary equipment fault indicators
• Two selectable battery charge currents
• Battery resistance monitoring to EN54-4/A2
• Mains fail simulation mode
• On-board temperature sensor, with an optional BF322 remote battery temperature sensor
• Can be customised with a BF423 configurator and PC (changing parameters takes the PSU outside the scope of EN54-4)
• Electronic functions comply with EN50131-6 grades 1-4 for security applications
