Although there are many sizes of suitable
battery, the sizes we usually recommend
are 12V 7Ah, and the enclosure has been
designed to hold this size battery.
To calculate the exact requirement, use the
battery calculation guide.
If batteries larger than 7Ah are required, a
separate battery box will have to be used
The panel should be connected to 220-240V AC by a 3A rated
spur to the fuse box with 1.5mm
2
to 2.5mm
2
3-core cable.
Nothing else should be connected to this supply
The connections are:-
Live to fuse,
Earth to centre connection,
Neutral to far connection
The Mains is protected by a quick blow 20mm 2A HBC fuse.
(Also known as HRC)
The incoming mains cable should be kept separate from
the zone cables to help minimise mains interference.
MAKE SURE ANY SPARE ENTRY HOLES ARE COVERED
WITH THE PLASTIC GROMMETS PROVIDED
It is advisable to apply power to the panel before connecting
any devices, to check for correct operation, and to familiarise
yourself with the fire alarm panels controls.
