9IDS 805 Installer Manual 700-266-02H Issued September 20093. End-of-Line Resistors/Tamper per Zone All zones are end-of-line supervised. Any unused zones must also be terminated with theappropriate 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 location11 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 resistorsshould be connected as per Figure 2 below. The 4K7 and 12K resistors are not included with thepanel but may be obtained from your local distributor of IDS products.Figure 2: Tamper per Zone ConnectionThe 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 tampercondition will be reported. If the panel is armed and tamper condition occurs the alarm will register a zone violation and atamper condition will be reported. Regardless of whether the panel is armed or not, if a zone is programmed as a priority/paniczone, 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 resistorsmust be connected in all zones. If the tamper facility is not used on a zone then the 12K resistormust be connected directly across the zone (i.e. between the zone input and ground) and the4K7 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.Figure 3: Resistors Used for Tamper per Zone
