The panel should be connected to 220-240V AC by a 3A
rated spur to the fuse box with 1mm

3-core
cable. Nothing else should be connected to this supply.
The cable should be fire resistant
The Live, Earth and Neutral connections are marked on the
PCB. 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.
Once the mains is connected, the protective cover should
be replaced BEFORE turning on the mains power. This will
minimise the chance of electric shock from the PCB.
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.
Although there are many sizes of suitable
battery, the sizes we usually recommend for
the Premier AD are 12V 7Ah, or 12V 12AH
To calculate the exact requirement, use the
equation in section 16, BATTERY
CONNECTIONS
The two batteries are wired in
series
.
The
+ve
of one battery is connected to the
red
battery lead.
The
–ve
of the other battery is connected to
the
black
battery lead.
The –ve of the first battery is connected to the
+ve of the second battery using the link wire
supplied.
When fitting the batteries, take care not to
damage the temperature monitoring
thermistor.
This is used to prevent
overcharging the batteries in high ambient
temperatures.
