BF560-12 (12 V DC, 2 A) Installation Instructions
EN 54-4, EN 50131-6 Boxed Power Supply Unit (PSU)
WARNING: THIS PSU MUST BE INSTALLED AND MAINTAINED BY A SUITABLY SKILLED AND TECHNICALLY COMPETENT
PERSON. THIS PSU IS A PIECE OF CLASS 1 PERMANENTLY CONNECTED EQUIPMENT AND MUST BE RELIABLY EARTHED.
The BF560-12 is a boxed mains input to regulated DC PSU, providing 2 A @ 12 Vd.c. nominal, designed for use with
fire and security systems. Combining the functions of a PSU, battery charging unit and battery monitoring unit, it
is fully compliant with EN 54-4 + A1 + A2, EN 62368-1 and has been tested to comply electrically/environmentally
with EN 50131-6 (Type A, up to Grade 4
All wiring must be installed in accordance with all applicable national, regional or local standards. In the UK this is
BS 7671 (IET Wiring Regulations). Fuses must comply with IEC/EN 60127-2. See Fig.1 for PSU connection details.
The requirement for the mains supply to the PSU is fixed wiring (≥1.0 mm
suitable three conductor system fed from an isolating switched fused spur at 3 A, or a 6 A Type B circuit breaker to IEC/
EN 60898-1. The mains supply must be exclusive to the PSU and be reliably earthed at the indicated earthing point.
HINT: As an alternative to a switched fused spur, a double-pole isolating switch with 3 mm air gaps on the contacts
& switching L & N only, may be used in the mains feed from the Main Distribution Board to the PSU, providing it
meets the appropriate wiring regulations.

This cable must be segregated from other cables and only
enter the panel through the top right-hand drill outs.
(Must be externally fused to ≤ 6 amps)

DO NOT operate the PSU without first connecting
this strap to the base earth distribution post.

Note: On a standard 'as-supplied' unit, DIP Switch 4 is OFF (DOWN) and a fault will occur on initial power-up if a
fully charged battery is NOT connected. See Table 2 - DIP Switch Settings (Fig.1).
Over Current / Over Load Protection: If the output load attempts to pull current in excess of the PSU rating, the PSU
will shut-down and attempt to auto-recover after approx. 10 seconds, and will continue to do so until the overload
is removed. If the PSU is subjected to a short circuit across the output terminals, the PSU may trip and require power
cycling to reset. Reset by switching off mains and disconnecting the battery, then wait for the red 'Hazardous Voltage
Present' LED to extinguish before re-applying mains and battery. Check the battery fuse (F2) has not operated.
WARNING: There is a risk of explosion if an incorrect battery type or size is used. Always dispose of used
batteries in accordance with the battery manufacturers instructions and local regulations. Batteries are heavy
and can produce dangerously high currents if shorted. Take care when handling and routing battery leads
to avoid damage. The battery may be safely secured by using cable ties if required.
