3GS CONTROLLER OVERVIEW
The 3GS Controller is the control unit for the 3GS
system. This PCB contains the core software for the
system. When power is applied to this unit, the controller
scans the ringnet for any attached devices and builds up
a system configuration. Any changes to this configuration
will be monitored by the controller and the appropriate
action taken. The controller stores all programmed data
in its memory, which is battery backed up.
The 3GS controller has 8 inputs and 4 outputs on board
– see “Controller PCB” on page 3-4. A ringnet
communications port provides an interface to the nodes
which provide intruder, access, and radio functionality –
see “Ringnet Communications” on page 1-5.
The Controller has 3 serial ports, one 9 pin D-type and
two 4-way terminal blocks. These ports are used for
connection to reporting devices:
● Central station via DM1200
● Remote monitoring station via modem or LAN -
TCP/IP
● Local monitor devices such as a PC or printer
● Programming tools for upload/download such as PC
or HHT
See “Serial Communications” on page 6-1.
The controller is powered through the PSU connection
socket. Depending on the system requirement, a
Europlex 3, 4, or 6Amp switch mode PSU must be used.
The controller also provides an interface for external
siren and monitors housing for front and back tampers.
