Installation manual

firmly anchored using the cable tie and adhesive pad provided
next to the cable entry hole. Do not run mains cable through the
same entry hole as low voltage circuit cables. Sharp metal entry holes
should be protected with edge strip or rubber grommets. Always
connect the earth from the mains cable to the panels mains earthing
point terminal block, use earth sleeving to protect the exposed earth
wire. Try to run cables neatly through the centre of the panel casing in
a loom, with branches coming from the loom as each zone cable is
connected to the terminals.
Clearly label all cables with their zone number and detector
location.
Mains Supply - 230 VAC
The transformer should be connected to an un-switched fused spur
power supply outlet. Where regulations require, connect a 16 AWG
green-jacketed solid conductor ground wire from the earth terminal on
the studs provided on the enclosure to a metal pipe, grounding rod or
other established earth ground for protection against lightning-induced
surge.
(( For UK Installations: The mains installation should be carried
out by a qualified electrician in accordance with Electrical
Wiring Regulations (BS 7671) and the current IEE regulations.
As this is a permanently connected equipment, the fixed wiring
must have a readily accessible disconnect device, e.g.
Un-switched fused spur.
(( Ensure that continuous current supplied from the AUX
terminals and outputs is less than 850 mA.
Ensure the supplied green earth bonding lead is connected to the front
cover using the spade prior to replacing the panel lid.
Back-Up Battery Supply - 7Ah (JP2)
Connect a 12V 7 AH sealed lead-acid battery to the BATT (JP2)
terminals. The Zone Expansion boards requires less than 35 mA.
Connect the positive terminal of the battery to the + terminal of JP2
and the negative terminal of the battery to the - terminal of JP2. The
battery provides standby power to the system in the event of power
failure and supplies additional current when required, e.g. to drive the
siren during an alarm. The battery current is limited to 2.5A by a
resettable fuse (F1).
(( The system may not operate correctly without a backup
battery.
Back-Up Battery Calculation.
Standards require that alarm systems must be designed and installed
with adequate battery back-up capacity to run the system for a
minimum number of hours upon a loss of mains power. To do this, first
establish the system ‘Quiescent’ Current (QC). This value in Amps
