EN54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual
6.4
Powering the Panel
Before applying mains power
to the control panel
make sure that you carry out the following checks and
procedures:
1
Check that you carried out all the instructions
described in
Section 6.2 Preliminary Checks
.
2
Prepare the mains supply wiring for connection as
follows:
i
Remove the outer cable sheath to provide sufficient
slack, approximately 100mm, in the wiring to assist
termination. Cut the Live (L) and Neutral (N) wires
about 20mm shorter than the safety earth. See
drawing at left.
ii
Form each wire in a ‘pigtail’ before taking it to its
termination point. Route the L and N wires such that
there is separation from the safety earth. See drawing
at below left. Secure the L and N wiring with the
supplied cable tie before terminating the L and N
wiring. The safety earth should not be secured by
the cable tie.
iii Connect the L and N wires (A) directly to the MTB
(B). The safety earth wire (C) MUST NOT be
terminated at the MTB but at the safety earthing post
(D) provided. See drawing at left.
Note:
The post (D) is located to the left of the mains cable
tie anchor (E). A 4mm, crimp-on, ring terminal is
provided for the connection of the mains safety earth
wiring to the post. This crimp will accept cable
conductor sizes between 0.5 to 1.5 mm
2
.
iv Terminate the safety earth wire using the supplied
4mm crimp-on, ring terminal (F), 4mm nut (G) and
spring washer (H) provided (see drawing at left).
6.4.1
Standby Batteries
The panel back box can hold up to two 12V, 7Ah standby
batteries. The batteries are not supplied with the panel.
Refer to
Section 8 Specification
for details of
recommended batteries.
Note:
The panel can function satisfactorily on batteries
only, if required, when mains power is not available.
However, this should only be done for short periods
to avoid inadvertant discharge of the batteries.
To install the batteries:
1
Install the batteries in the back box. The batteries
should be positioned so that their terminals are close
enough to allow connection of the short interlink cable.
