BF562-5 (24 V DC, 5 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 EARTHED.
The BF562-5 is a boxed Mains input to regulated DC PSU providing 5 A @ 24 V d.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 tested to comply electrically/environmentally with EN 50131-6
(Type A, up to Grade 4*, Environmental Class II) and conforms to the relevant EU-Directives and EU-Regulations: (EU)
No. 305/2011 – Construction Product Regulation; 2014/35/EU low voltage directive and 2014/30/EU EMC directive.
The PSU is an approved product by BRE. Approvals are pending for AFNOR and VdS European notified bodies.
INSTALLATION
Location
The PSU must be installed indoors, positioned to avoid accidental damage, and MUST NOT be subjected to dust,
conductive or corrosive gases or liquids, nor subject to temperatures, input voltages and electrical loads outside the
stated operating range. Ideally, the indicators should be at eye level and the ambient light level should allow the
status of the indicators to be clearly visible.
Mounting
Using the five mounting holes provided, mount the metal base securely onto a vertical wall, ≤2 m mounting height.
Assess the condition and construction of the wall and use suitable screw fixings for the in-service weight of the
product. The mounting holes are suitable for use with No.8-10, or
created during the mounting process must be kept out of the enclosure and due care must be taken not to damage
any wiring or components.
Wiring and Cable Entry
All wiring should be installed in accordance with the current edition of the IEE Wiring Regs (BS 7671), or relevant
local and national standards. The requirement for the Mains supply to the PSU is fixed wiring (≥1.0 mm
either using 3-core cable, or a 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.
For compliance with EN 54-4 the PSU must be closely coupled with the CIE.
The PSE must be physically connected to the CIE using some type of protective
conduit to ensure power/signal line integrity.
HINT. As an alternative to a switched fused spur, a double-pole isolating
switch (S) with 3 mm air gaps on the contacts & switching L & N only, may be
used in the Mains feed from the Main Distribution Board (A) to the PSU (C),
providing it meets the appropriate wiring regulations (see drawing right).
In order to maintain cable segregation from other cables, the incoming Mains cable should be fed into the panel via
a top knockout (provided on the metal base). Knockouts should be removed with a sharp, light tap using a 6 mm flat-
bladed screwdriver. Always ensure that if a knockout is removed, the hole is filled with a good quality 20 mm strain
relief, cable gland. Any unused knockouts must be securely blanked off.
WARNING: DO NOT ATTEMPT TO CONNECT THE MAINS SUPPLY TO THE PSU UNLESS ALL COMPONENTS ARE
SECURELY INSTALLED IN THE ENCLOSURE!
Terminate the Mains cable at the PSU's connector block CONN1 (see Figure 1 below).
Figure 1 - PSU Layout and Mains Connections (Full Protective Cover & Cable Cover Shown Fitted)
See Technical Specification overleaf for further details
Incoming Mains Cable
This cable must be segregated from
other cables and only enter the
panel through the top knockouts.
Mains Fuse (F1)
Exposed live parts under fuse
cover. Isolate before removal.
Hazardous Voltages Present LED
When lit red, hazardous voltages
are present under the two covers.
Allow to discharge for at least 5
minutes before removal & handling.
