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:

No of Biscuits at

end of cable

Max Cable

Distance (m)

Max. cable loss

resistance, ends

shorted at panel

30 40m 6 Ohms

15 68m 11 Ohms

7 107m 17 Ohms

3 150m 24 Ohms

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.

The wiring for remote keypads and internal

sounders (loudspeakers) should not be

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.
