Connecting Detection Devices to Panel Zone Inputs
The panel comes with six factory programmed onboard hardwire zones (see
“Accessory Modules Menu” on page 60 for factory settings). Zone inputs 1
through 6 are supervised using a 2k-ohm, end-of-line resistor (included with
panel) at the last device on the circuit.
Note
: Install an end-of-line resistor on all unused, factory programmed, onboard
panel zones.
All six zones accept either normally open (N/O) or normally closed (N/C)
detection devices (see Figure 8 on page 15).
The maximum loop resistance for each zone input is 300 ohms, plus the 2k end-
of-line (EOL) resistor.
Connecting Intrusion Detection Devices
Figure 8 on page 15 shows the typical wiring for N/C and N/O door/window
intrusion detection.
