The BF562-3 is a boxed mains input to regulated DC PSU, providing 3 A @ 24 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 and has been built to comply electrically/environmentally with EN 50131-6
(Type A, up to Grade 4 #1, Environmental Class II). The PSU is an approved product by BRE and VdS.
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.

BF562-3 (24 V DC, 3 A) Installation Instructions
EN 54-4, EN 50131-6 Boxed Power Supply Unit (PSU)
Fig.1 - PSU Layout & Connections
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 batteries, then wait for the red ‘Hazardous Voltage
Present’ LED to extinguish before re-applying mains and batteries. 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 batteries must be safely secured by the cable ties (supplied in the accessories).
Note: On a standard ‘as-supplied’ unit, DIP Switch 4 (‘Battery Not Fitted’) is OFF (DOWN) and a fault will occur on
initial power-up if fully charged batteries are NOT connected. See Table 2 - DIP Switch Settings (Fig.1).

PHYSICAL
Dimensions: 404 mm (W) x 404 mm (H) x 110 mm (D)
Weight / Construction: 5 kg (without batteries) / Metal lid and base
Enclosure finish: RAL7035 textured
FITMENT & OPERATING CONDITIONS
Five mounting holes are provided for Ø4-5 mm CSK screws. Mount ≤2 m on a vertical surface. Wall condition, construction and in-service weight
must be considered when choosing screw fixings. For compliance with EN 54-4 the PSU must be closely coupled with the CIE. The PSU enclosure
has an IP30 rating (to EN 60529) and is designed for indoor use only. The components are selected to operate within their specification when the
environmental conditions outside the enclosure comply with class 3k5 of the latest edition of IEC 721-3-3. Temperature range: -10oC to +40oC.
Maximum humidity: 95% non condensing.

E&OE. No responsibility can be accepted by the manufacturer or distributors of these power supplies for any misinterpretation of this instruction, or
for the compliance of the system as a whole. The manufacturers policy is one of continuous improvement and we reserve the right to make changes
to product specifications at our discretion and without prior notice.
Important Note about Batteries: This PSU complies with EN 54-4 and therefore must monitor and report battery
resistance faults when batteries are fitted. The battery resistance fault threshold is directly related to the ability of
the batteries to deliver the rated current to the load.
VRLA battery resistance varies with manufacturer quality, battery age (from date of manufacture, particularly if left
uncharged during shipping or storage), temperature, size and state of charge. It is not uncommon for so called “new”
batteries to be in excess of six months old if the supply chain is not properly managed. It is therefore important to fit
good quality, new batteries that have not been shelf soiled during shipment
or storage. VRLA battery resistance naturally increases in cold environments
and may make marginally usable batteries at room temperature unusable
at low temperatures. Careful siting of the product may alleviate some of
the natural limitations of VRLA batteries. Smaller batteries have a higher
resistance than larger batteries as shown in Table 3 right.
VRLA battery life is typically rated at 20°C. Raising the temperature by 10°C
will halve the expected usable life of a VRLA battery. Operating at 40°C
will therefore lead to only a quarter of the expected life. High temperature
also degrades battery life during shipping and storage.
