2.17.1 ZONE CONNECTIONS (SPC-ZX4/ZX8)
Each input terminal, allows you to connect one detection device. These devices are connected exactly as
shown in Figure 2-5 on page 11. Devices connected to the Zone Expansion Module's input terminals must
be enabled as described in Zone Input Assignment on page 50 and the its parameters must be defined as
explained in Zone Programming on page 20. The Zone Expansion Modules will communicate the status of
the zones to the control panel through the communication bus.
The Zone Expansion Modules do not support the zone doubling (ATZ) feature.
2.17.2 ZONE EXPANSION MODULE TAMPER CONNECTIONS
The Zone Expansion Modules do not come equipped with a tamper switch. Although, if required you can
enable Tamper Recognition (Zone Module) (see page 50), which will reserve input terminal Z1 as a tamper
switch input. This allows you to connect a tamper switch to input Z1 as shown in Figure 2-9. When a
tamper is detected on the module, it will send a tamper report (originating from the zone assigned to input
Z1) to the control panel via the communication bus.
With Zone Expansion Module Tamper Recognition enabled, do not connect anything other
than the tamper switch to input terminal Z1.
