(3) Single zone with end of line resistor, tamper and wiring short circuit
detection
It is recommended to congure the center in this mode, because despite being the
most complex to connect the sensors, it is the one that offers the highest security for
the alarm system. This connection mode is valid for all zones of the alarm center. See
below, the way to connect sensors that have tamper and sensors that don’t have
tamper, for example: opening sensors.

(4) Dual zone without end-of-line resistor
This conguration is the least secure for Dual Zones, since it does not recognize short-
-circuiting of the wiring. The sensor connected to the 2K2  resistor becomes zone 1,
the sensor connected to the 3K9  resistor in zone 11.
