FAQ
What certifications does the BF560-12 have?
The BF560-12 is certified to EN54-4/A2 by both LPCB and VdS, with AFNOR certification pending. It also complies with EN50131-6 grades 1-4 for security applications.
Can the PSU be customised for specific requirements?
Yes, the BF560-12 can be customised using a BF423 configurator and PC. Configurable parameters include float voltage temperature compensation, battery charge rate, battery impedance and input/output settings. However, any customisation is outside the scope of EN54-4 and must be tested by the responsible person.
What battery sizes are supported?
The PSU supports battery capacities from 2Ah up to 12Ah, with maximum battery sizes of 1 x 12V 3.2Ah VRLA (with STU plate fitted) or 1 x 12V 7Ah VRLA (without STU plate fitted).
How does the PSU help with BS5839-1 compliance?
The BF560-12 solves compliance issues when connecting fire alarm systems to remote monitoring centres via 12V security STUs. It provides the EN54-4 features required by BS5839-1, including battery impedance monitoring, temperature compensated charging and dedicated mains supply.
What do the LED status indicators mean?
The PSU status LED shows different flash patterns: 1 flash = Mains Failure, 2 flashes = Battery Voltage Low, 3 flashes = Battery Voltage Critical, 4 flashes = Charger Failure, 5 flashes = Charger OK, 6 flashes = No Batteries Fitted, 7 flashes = Battery Resistance Fault, 8 flashes = Output Over Voltage.
Is an encased version available?
Yes, the BF560-12/E encased PCB version is also available for applications requiring additional protection.
