BEFORE SWITCHING ON THE POWER
1. Detectors (or key switches) can be connected in two ways:
Conventional: One zone each is required for both tamper and the alarm. Both zones should be
closed with an end-loop resistor (4.7 kOhm). Program the ‘zones’ menu as
‘Alarm’

Dual loop: The alarm and tamper are placed together in one zone. The zone has two end-loop
resistors (4.7 kOhm) to differentiate between alarm and tamper. Figure 2 shows how
they are connected. Program the ‘zones’ menu as ‘Dual’.
