INTRODUCTION
We recommended you read this manual before attempting installation in
order to fully utilise the panels functions in your application.
An understanding of the manual will lead to a quicker, easier installation of
the system.
The Nexus 8 has been designed to simplify the installation process, making
wiring easier and subsequently quicker. Individual tampers for each zone
have replaced a single global tamper and each zone now has a 12v auxiliary
power supply. A detachable gear tray aids wiring and protects the printed
circuit board from damage.
PLANNING THE INSTALLATION
• To maximise the system’s effectiveness pre-plan the installation.
• Consider the layout of the building and each of its access points.
• Use the pre-programmed system mode which is best suited to the
building. (See programming guide p.18)
A common layout is shown below, using zone preset option 91 (see
programming guide for details of how to set zone preset options p.18). This
option has been chosen as it best suits the installation, taking layout and user
requirements into account. As the majority of forced entry’s are made through
the front and back doors, they have been fitted with contacts. PIRs have
been fitted guarding against entry through windows, with the exception of
zone 4 which is protected by a vibration detector, making the room suitable
for housing pets. Both zones six and seven are omitted in part sets 1 and 2,
giving access to bedrooms during night setting. The panic attack is located
upstairs close to each of the bedrooms as most burglaries take place at night.

MAINS CONNECTION
• Mains supply is connected
to the panel via a three-way
green terminal block located
on the transformer below
the mains cable entry.
• The supply should come
directly from a consumer
unit through a 3amp fused
spur.
BATTERY CONNECTION
• A sealed lead acid
rechargeable battery must
be connected to the panel
via the two way terminal
block (B+/B-).
• This is situated next to the
battery fuse on the
transformer PCB.

MOUNTING THE PANEL
• Use the template on the

aid hole marking.
• Drill used should be a size
10 mason bit.
• Plug holes with rawl plugs.
• Use slotted fixing holes to
help level the panel before
fixing it in place with four
1.5”x8 wood screws.
CABLE ENTRY
• 10 individual cable entry’s
are sited beneath the gear
tray.
• Each is individually marked
for ease of cable
identification.

REMOTE KEYPADS
• The Nexus 8 allows up to 4 remote keypads to be used with the system.
• Wiring is via three terminal blocks located at the bottom of the keypad
PCB Cable entry to the keypad is from either top or bottom knockout.

ADDRESSING ADDITIONAL KEYPADS
If two or more keypads are used in an installation, each has to be assigned
an address number in order to communicate with the end-station. This
address number is factory set to 1 and so must be changed on additional
keypads.
To set address number on an additional keypad
• Ensure keypad to be added is not yet powered.
• Remove keypad’s front cover.
• Electrically connect keypad to endstation.
• The keypad will display its address number i.e.
• Press 1 to 4 to change keypads address.
• Press YES to accept and a conformation bleep will be heard.
• Replace keypad cover and test keypad can control the system.
PANIC ATTACK
• The remote keypad also features a
panic attack function.
• Panic attack is operated by
pressing both buttons situated
above the keypad display.
• Panic attack function can be
disabled if required. (See
programming menu p.20)

VIBRATION DETECTORS
• If two or more detectors are connected to one zone, power is wired in
parallel, whereas alarm and tamper circuits must be wired in series. • Where 6-cores are used to wire latching detectors, power supply is taken
from tamper circuit. The zones’ + terminal should not be used.
