Mounting The Base Onto A Wall; Planning The Cable Layout In The Panel; Mains Wiring - XFP XFP501E/X Engineering Manual

XFP 16 ZONE ANALOGUE ADDRESSABLE FIRE ALARM PANEL

Mounting the base onto a wall

The panel can be surface, or semi-flush mounted, onto a vertical wall, ≤2 m mounting height, using the
five mounting holes provided (see Fig. 2 below). To access the mounting holes, first remove the panel's
lid and base PCBs, as detailed on page 5. The mounting holes are suitable for use with No.8-10 or 4-
5mm countersunk screws. Always assess the condition and construction of the wall and use suitable
screw fixings for the in-service weight of the product. Any dust or swarf created during the fixing
process must be kept out of the base. Note that the central mounting hole can be used to temporarily
hang the back box so it can be levelled and its remaining fixing points marked for drilling.

Do not drill any additional holes
for cable entry in this shaded area.
This is where the PCBs and
backup batteries will be located.

Planning the cable layout in the panel

All cables should be brought into the panel via the drill outs provided.
Note that the analogue loop and conventional sounder circuit cabling is
classed as low voltage and MUST be segregated away from Mains voltages.
Careful planning is needed to ensure this (see Fig. 2 above for guidance).
We recommend tails of at least 20-30cm are left inside the panel to ensure
straightforward connection of the field wiring to the panel's terminals.
Drill centre points are provided in the panel base to aid drilling tools. Cut
out suitable holes in the panel using a hole saw directed by a pilot bit in
the centre of the hole saw (see right). Always ensure that if a hole is cut
out it is filled with a good quality strain relief cable gland. Any unused
holes must be securely blanked off.

Mains wiring

All wiring should be installed in accordance with the current edition of the IEE Wiring Regs. (BS 7671), or
relevant national standards. The requirement for the Mains supply to the panel is fixed wiring (no less
2
than 1mm and no greater than 2.5mm
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 panel and be reliably earthed at the indicated earthing post.
Hint! As an alternative to a switched
fused spur, a double-pole isolating
switch (S), with 3mm air gaps on the
contacts & switching L & N only, may
be used in the Mains feed from the Main
Distribution Board (A) to the Panel (C),
providing it meets the appropriate wiring
regulations (see drawing right).
