and Setup
2.3.3 Single Zone Configuration (Loops 1-8)
When wiring the on-board sensor loops in the
single zone configuration, install the resistor of
the appropriate value (2.2 kΩ resistors are
provided) at the far end of the sensor loop to
provide a reference for supervision. You can
connect dry contact sensing devices in series
(Normally-Closed) and/or in parallel (Normally-
Open) to any of these loops (see Figure 16).

Loop resistance limits the number of Normally-
Open and/or Normally-Closed detection devices
that each sensor loop can supervise. The total
resistance for wire length and contacts, minus
the end-of-line resistor, must not exceed 100 Ω.

2.3.4 Doubled Zone Configuration
When wiring the on-board sensor loops in the
doubled zone configuration, install the resistors
of the appropriate value (2.2 kΩ and 3.65 kΩ) as
shown in Figure 17. The control panel can be
configured to function with either Normally-Open
or Normally-Closed contacts. Normally-Closed
contacts are recommended.
Each sensor loop is monitored as a
separate zone.
