3. End-of-Line Resistors/Tamper per Zone

All zones are end-of-line supervised. Any unused zones must also be terminated with the
appropriate resistor.

The end of line resistor should be placed inside or as close to the sensor as possible.

If the zones are not programmed to report tamper by zone i.e. a [0] is programmed into location
11 then use the 3K3 end-of-line resistor.

If the zones are programmed to report tamper by zone, the 4K7 and 12K end-of-line resistors
should be connected as per Figure 2 below. The 4K7 and 12K resistors are not included with the
panel but may be obtained from your local distributor of IDS products.
Figure 2: Tamper per Zone Connection
The operation of the tamper is as follows:

If the panel is not armed and a tamper condition occurs, the siren will not sound but a tamper
condition will be reported.

If the panel is armed and tamper condition occurs the alarm will register a zone violation and a
tamper condition will be reported.

Regardless of whether the panel is armed or not, if a zone is programmed as a priority/panic
zone, a tamper will register a panic condition as well a tamper condition.

If the tamper per zone is enabled, it affects all zones and therefore both end-of-line resistors
must be connected in all zones. If the tamper facility is not used on a zone then the 12K resistor
must be connected directly across the zone (i.e. between the zone input and ground) and the
4K7 resistor is used as the normal end-of-line resistor.

The colour codes for the 12K and 4K7 resistors are as seen in Figure 3 below.
