20 ProSYS Installation and Programming Manual
NOTES:
It is recommended that you use an End-of-Line Resistor at the far end of each hardwired zone
to prevent short-circuits (16 resistors are supplied).
For a zone with a tamper switch, you can use a Double End-of-Line Resistor to save additional
Main Panel connections (refer to
Figure 6 on page 21).
3 Terminate unused zones at the Main Panel.
4 Connect the power to the sensors and/or detectors, as described in Wiring the Auxiliary
Devices, page 22.
The following diagrams illustrate the various possible zone connections depending on
the zone expanders.
Connection on the main units or on the G3 zone expanders (ProSYS EZ8G3, EZ16G3):
