3. Installation
Detector Circuit Connections
The left hand edge of the main PCB provides 14 connectors that can be used
for up to 8 zones.
Four Wire CC Connections
Figure 12 shows how to connect four wire CC zones. Note that pairs of alarm
contacts share contacts. You should wire the tamper contacts of all detectors
in series and then connect them to the contacts marked "A/T".The control
panel provides enough connectors for eight four wire circuits. If you wish to
connect 16 four wire circuits you must fit a 9755 hardwired expander card
(see "Connecting a 9755 Expander").
