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

rear of the Nexus 8 box to

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.

BELL BOXES

• Always consult manufacturers instructions before installation.

• Use 6-core cable (5-cores required).

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.

• Use 4-core cable (3-cores required)

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)

10 PROGRAMMING ADDITIONAL KEYPADS

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.
