Installation
Connecting AC Mains
The AC Mains supply is connected to a 3 way 'Euro Type' fused
terminal block, which is fitted with a fuse (see page 37).
All other wiring MUST be carried out before AC mains is connected to the control
panel.
After connecting the AC Mains, fit the mains cover, this can be found in the spares
bag.
To transformer
Connecting Batteries
Up to one 12V 7Ah battery can be fitted inside the control panel to
provide continued operation in the event of an AC mains failure.
All other wiring MUST be carried out before the battery is connected to the control
panel.
Connect the red battery lead to the positive terminal of the battery
and connect the black battery lead to the negative terminal of the
battery.

Veritas R8 Plus & Excel Installation Manual
Installing Remote Keypads
A maximum of 6 remote keypads can be connected to the keypad
network. The Veritas R8 Plus and the Veritas Excel supports both
LED and LCD keypads.
The networks are made up of four terminals incorporating power and
data. To ensure correct operation, all four terminals on the device must
be connected to the corresponding terminals on the control panel, or
previous keypad. The table below shows each terminal and its
description:

Devices can be connected using 4-core cable. However, it is recommended
that 6 or 8-core cable is used as the spare cores can be used to 'Double Up'
on the power connections if needed.
Standard 7/0.2 alarm cable can be used for most installations. However, under
certain conditions it may be necessary to use screened cable.
Cable Distances
The maximum recommended distance for devices when using
standard 7/0.2 alarm cable is:
100m for each branch when using the star (parallel)
configuration
When using a daisy chain (series) configuration the maximum
distance will depend on the number of devices connected on
the chain. The more devices that are connected, the shorter
the distance to the last device (this is due to voltage drop in
the cable)
Whichever method of wiring configuration is used, ensure that the
voltage between the '+' and '–' terminals at each device is no lower
than 10.0V when the system is running on the standby battery.
Keypad Addressing
Each keypad MUST be given a different address using the DIP
switch on the PCB as follows:

NEVER set two RKPs to the same address. Keypads are factory set to Address 1. If
the keypad is powered but offline (i.e. T and R not connected) it will display its
address. If an invalid address is selected, the keypad will sound an error tone.
