Zone Connections
(control panel 4 Wire option)
Three wiring methods are possible for the zones located on the main PCB in the
GardTec
872
control panel. The first is 4 wire or normal type wiring, if this default
option is chosen 8 double pole zones are available (8 alarm zones and 8 tamper
zones).
To use the 4 wire option the control panel should be programmed for 8 (4 WIRE)
in the programming section 'PROGRAM ZONE WIRING' (option No.50).This is the
default setting.
Each zone is fully programmable. Details of the zone options available are given in the
section 'Programmable Options Description'. Each alarm zone is marked as AZx and is
a positive loop, each tamper zone is marked as TZx and is a negative loop.
If pressure pads or other normally open devices, are to be used the AZ zone should be
shorted to the TZ zone by the device in order to activate the AZ zone.
Typical wiring of various detectors is given in Fig. 23
