GX-Series Control Panel Installation and Setup Guide
2-12
Wiring Zones
The zones on GX-Series panels can be Double Balanced (default) or End of Line. Zones can be programmed
with different resistance ranges for zone status activation (see Parameter 51.46 = Parameters.Zone
Resistance). Refer to Table 2-7 (Double Balanced) or Table 2-9 (End of Line) for details of the zone
resistance and resulting conditions. The system default is Option 9, giving fault monitoring on 1k double
balanced wiring.
NOTE: The circuit debounce time (the period the zone must remain in a state to register a change in condition) is
300 milliseconds by default.

Table 2-6. Double Balanced Zone Resistance and Conditions
Option 09 - 1k Fault Double-balanced (default)
The wiring in Figure 2-12 should be used if the detector uses combined fault and mask signaling. A mask
condition is generated if an alarm and fault are signaled at the same time. Alternatively, if the detector has
separate fault and mask indications then the wiring in Figure 2-13 should be used.
