C-TEC 12V 2A EN54-4 Switch Mode Boxed Power Supply Unit (BF560-12)

The C-TEC BF560-12 is a 12V 2A switch mode/digital hybrid power supply in a PVC enclosure, certified to EN54-4/A2 by the LPCB and VdS. It is ideal for powering 12V security STUs or autodiallers used to signal fire alarms to a remote monitoring centre, helping such installations comply with BS 5839-1. An optional STU mounting plate (BF360SP) fits inside the enclosure.

Key features

• 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)
