Number Name Description
14 Zone inputs The controller provides 8 on-board zone inputs that can be monitored using a
variety of supervision configurations. These configurations can be programmed
from system programming. The default configuration is Dual End of Line (DEOL)
using resistor values of 4k7. See Wiring the zone inputs on page45.
15 Tamper
terminals
The controller provides 2 additional tamper input terminals that can be connected
to auxiliary tamper devices to provide increased tamper protection. These
terminals should be shorted when not in use.
16 Serial port
terminal block
Serial port terminal block (TX, RX, GND) may be used to interface to an external
modem or PC terminal program. Serial port shares a communications channel with
the back-up modem. If a back-up modem is installed, ensure that no devices are
connected to this serial port.
17 Ethernet
interface
The Ethernet interface (100mbps) provides for the connection of a PC to the
controller for the purposes of programming the system. The 2 Ethernet LEDs
indicate the status of the Ethernet connection. The left LED indicates data activity
on the Ethernet port; the right LED indicates the Ethernet link is active.
18 USB
Config
The micro USB Config interface is used to access browser programming, SPC
Connect Pro, or a terminal program.
19 Optional plug-
in modules
A primary (left slot) and back-up (right slot) module can be connected to the
controller. These modules can be GSM or PSTN modems offering increased
communication functionality. The back-up modem may also house a two-way
wireless module.
20 Front tamper This on-board front tamper (switch and switch) provides the housing tamper
protection.
Note: The front tamper is not used in the G5 housing.
21 Status LEDs Two LEDs display the status of system parameters. See Controller status LEDs on
page265
