the chassis plate and allow easy access to the batteries.
Figure 2 Installing the Enclosure
It is recommended that the chassis plate be removed from the enclosure before fitting the panel to the wall. To
remove the chassis:
▪Unhook the chassis plate from the wing brackets and swivel 90° to slide into the vertical lock position as
shown in Figure 2.
▪Unplug the 8-way connector feeding the 27.5 V DC supply to the Main PCB.
▪Carefully remove the chassis from the rear enclosure by pulling it forward out of the vertical locking
position. Put in a safe place to prevent accidental damage.
NB: Do not lift the chassis by holding onto any of the printed circuit cards. Hold the chassis by the metal
plate only.
NB: Do not remove or tamper with the “DO NOT REMOVE” sticker to screw out the harness, this will void the
warranty. Unplug the harness only from the Main PCB and leave it connected to the PSU.
Firstly, remove the required knockouts for the installation wiring. There are sufficient knockouts on the top of the
ABS and Standard Enclosures for all installation wiring. In addition, there are knockouts at the top of the back
wall for rear entry cabling, if required.
The Weatherproof Enclosure has cable entry points at the bottom of the enclosure. Remove the rubber glands
to utilise the cable entry point. Cable entry should only be from the bottom through the provided points with
compression glands to ensure the integrity of the enclosure is maintained.

1.8 WIRING INSTALLATION
All electrical wiring installation work should be carried out in accordance with the code of practice or applicable
national standards appropriate to the country of installation.
To maintain electrical integrity all zone, input, output, and communication line wiring should be segregated from
the AC Mains wiring and be wired using cable with insulation suitable for the application.
To minimise the effects of EMC interference, all data wiring circuits should be wired with a twisted pair of
conductors with a cross sectional area suitable for the loading conditions.
In areas where cabling may come into contact with high frequency interference, such as portable radio
transceivers etc., the data wiring cable should be of a twisted pair construction within an overall screen. Care
should be taken to correctly terminate this screen, refer to the relevant sections of this manual for further
information for each circuit type.
NB: Minimum/Maximum cable size for all external connections is limited to 0.5 mm²/2.5 mm² (22 –14 AWG).
1.8.1 RECOMMENDED CABLE ROUTING
It is recommended that the typical routing arrangement shown in Figure 7 and Figure 8 be followed.
Segregate the low voltage wiring (Zone Circuits, Sounder Circuits and AUX Supply) from the AC Mains Wiring.
Segregate any wiring connected to the relay contacts.
Refer to the specific sections on how to install AC Mains Input and Loop, Sounder, Relay and AUX Outputs
Circuits.

1.8.4.1 PSU LED INDICATIONS
The power supply continuously monitors the AC supply, the battery connection, the battery charging voltage,
and the output supply voltage. It will bring up the appropriate Fault conditions if these are outside of
specifications. These faults will be indicated by the respective LEDs on the Power Supply PCB –see Figure
20 below.

1.8.4.2 PSU FAULT INDICATIONS
◼AC Fault
The AC Fault LED, Supply Fault Relay and General Fault Relay activates. When the Fault is cleared,
indications and relays restore immediately.
◼Earth Fault
The Earth Fault LED and General Fault Relay activates. When Fault is cleared, indications and relay
restore within 30 seconds.
◼Charger Fault
The Charger Fault LED and General Fault Relay activates. When the Fault is cleared, indications and
relay restore within 30 seconds.
◼Battery Fault
The Battery Fault LED and General Fault relay activate. When the Fault is cleared, a panel reset or hard
reset on the PSU is required to restore indications and relays, or alternatively the fault will clear once a
successful load test was complete.
◼Output Fault
The maximum continuous operating output current is 1.2 A. Should you exceed 1.2 A, three modes are
provided to protect the output or to provide additional current, depending on the amount of current draw.
▪Boost Mode
‒Should the current draw exceed 1.2 A, the 27.5 V DC output Fault LED will flash, and the
battery charger circuit will be shut down.
‒If the 27.5 V DC output current draw exceeds 1.2 A, but is less than 1.8 A, for more than
10 minutes, the General Fault Relay and the 27.5 V DC output LED will be on solid.
The Charger Fault LED will also be solid on to indicate the charger is still off due the additional
current drawn on the output.
‒The 27.5 V DC output remains active.
‒When current draw is reduced to below 1.2 A, LED indications, relay and charger will restore
automatically within 30 seconds.
▪Overload Mode
‒Should the current draw exceed 1.8 A, the 27.5 V DC output Fault LED will flash, and the
battery charger circuit will be shut down.
‒If the 27.5 V DC output current draw exceeds 1.8 A, but is less than 2.5 A, for more than
10 minutes, the General Fault Relay and the 27.5 V DC output LED will be on solid.
‒The output will shut down and attempt to restore every 30 seconds; this will continue until the
load is reduced to below 1.8 A.
‒The charger will switch back on automatically.
‒When current draw is reduced to below 1.8 A, the 27.5 V DC output will restore automatically
after 30 seconds into BOOST MODE condition. The general fault relay will remain on.
‒When current draw is reduced to below 1.2 A, the relay and charger will restore automatically
within 30 seconds. The Output Fault LED will be solid on and requires a hard or soft reset to
clear.
