System Installation

ID Loop Wiring (TS690ID Only)

Each ID device is connected across a two-wire ID
loop. Apart from observing the correct polarity,
any wiring configuration can be used, as shown in
the figure below.

Cabling Requirements

The ID loop can be wired using standard 4 core
cable, this allows 2 cores to be used for the ID
devices and 2 cores for supplying 12V power for
PIR's etc.
The number of devices permitted per cable run is
governed by the resistance of the cable used.
Standard 4 core alarm cable (7/0.2mm) has a
resistance of approximately 8 Ohms per 100
metres and as a guide the maximum number of
devices that can be connected at the END of a
single cable run is as follows:

If a different type of cable is used, the distances
should be recalculated. e.g., if 7/0.4mm cable is
used, a single run of 80 metres would support 30
devices on the end as the resistance of the cable
is halved.
When installing the ID loop wiring It is usually more
practical to run several cables from the control
panel to the different areas of protection. This
effectively reduces any distance problems and
makes fault finding much easier.
To reduce the likelihood of induced interference
and wherever possible, cables should not be
positioned along side mains power, telephone or
other data transmission cables, or run within the
same ducting or trunking as any other cables.

connected in the same multi-core as the ID loop.
Included in the spares pack is a 47nF
capacitor. Although not necessary for
correct operation of the system, it will
improve the system noise immunity if
connected across the ID loop at one of the
devices furthest from the control panel.
