Wiring the External Sounder
Always consult the manufacturer's connection instructions. The
external sounder and strobe are connected to the five terminals
labelled SAB on the control panel as follows:
Terminal Description
A Permanent Positive Supply (+12V)
B Switched Negative to Activate Sounder
C Negative Tamper Return
D Permanent Negative Supply (0V)
S Switched Negative to Activate Strobe
Figure 5 - Typical SAB Connections
An external sounder is often referred to as a 'bell' or 'bell-box'
even when it is actually an electronic siren.
The control panel is supplied with a link fitted across the Bell
Tamper to simulate a closed circuit. This link would usually
be removed during installation.
If the strobe is a separate unit take the strobe positive supply
from 'A' as well.
A self-activating bell/sounder (SAB) has a built-in battery.
After connecting this battery the sounder will usually sound
until its cover is fitted and it is supplied with power from the
control panel.
Terminal B may be programmed as switched negative
removed rather than switched negative applied to activate
sounder (see page 21). This is useful for SCBs where B
would then be used to provide the permanent negative
supply.
Popular SAB Wiring Diagrams
The following diagrams illustrate how to connect the control panel
to the most popular makes of SAB:
Texecom Odyssey.
Figure 6d - Volumatic Flashguard.
Wiring a Communicator
The control panel has eight outputs, which can be used for
connecting to a stand-alone communicator. The table below shows
the characteristics for each output:
Terminal Type Current Operation
1 Fire 10mA Switched 0V
2 PA 10mA Switched 0V
3 Intruder 10mA Switched 0V
4 Set/Unset 10mA Switched 0V
5 Abort 10mA Switched 0V
6 Zone Lockout 10mA Switched 0V
7 Duress 10mA Switched 0V
8 Confirmed 10mA Switched 0V
L/M Line Monitor N/A 0V removed = Fault
R/R Remote Reset N/A 0V applied to reset
The operation of ALL outputs can be inverted if required (see
page 34).
It is NOT possible to invert the individually outputs.
Following an alarm, the Zone Lockout output will activate at
the end of the 2
nd
Intruder time if any zone remains open.
Do not use non-latching communicator outputs if selecting
Automatic Omit (see page 22).
The operation of the R/R input may be inverted from 0V to
reset to 12V to reset if required (see page 34).
The L/M input should be connected to 0V (AUX-) if not
required, otherwise Bell Delay will not operate.

Connecting a Computer
The Veritas R8 Plus and Veritas Excel both support local uploading
and downloading between the control panel and a PC running Veritas
UDL software. Uploading and Downloading can be used to program
and interrogate the control panel.
