Output Expander Modules (OPX)

Up to four output expander modules may be fitted to the Gardtec 840 control panel.
These modules may, if required be wired in a chain of zone expanders or on a
separate leg(s). The zone expanders only require four cores for interconnection,
if Output Expanders are used on the same leg five cores will be required (see
page 38).
Two types of module are available:-
Four open collector outputs. Max current sink 350mA each.
Four change over relays. Contact rating 1A 12V (resistive).
Each Output Expander (OPX) has a bank of four jumper switches labelled OPX1 to
OPX4. The output allocation is as follows:-
Jumper Position Output No (LCD)
OPX1 OP1
OPX1 OP2
OPX1 OP3
OPX1 OP4
OPX2 OP1
OPX2 OP2
OPX2 OP3
OPX2 OP4
OPX3 OP1
OPX3 OP2
OPX3 OP3
OPX3 OP4
OPX4 OP1
OPX4 OP2
OPX4 OP3
OPX4 OP4
Notes: If required, two expander cards may be configured on the same ident to
enable duplication of outputs.
When using any devices that consume current, consideration MUST be
given to the overall current available from the control panel.
Additional PSUs may be connected to the EXT PSU terminals on the
transistorised version. If this option is used the PSU (JP6) jumper
should be moved to the EXT position.
The invert link on the card will invert all the outputs of the card.

ID Expanders

The Gardtec 840 ID Expander card allows thirty detectors to be fitted on a four wire
run using industry standard ID biscuits or ID compatible devices. Two ID expander
cards can be fitted to the control panel. The control panel zones may still be pro-
grammed as 'Normal (4 wire)', 'Two Wire' or 'Two Wire EOL. When used to full capaci-
ty this allows the Gardtec 840 to have up to 16 control panel zones plus 60 ID zones.
Each ID expander may be wired back to the control panel with standard alarm four
core cable.
Wiring Configurations
Several configurations may be used for wiring the ID expanders to the control panel,
these are:-
One ID Expander onboard the control panel PCB.
The expander is simply plugged across the molex pins marked as EXP1 and EXP2
One ID Expander remote from the control panel PCB.
This will require a Remote Expander cable (Part No. 01-094). This cable is plugged on
to EXP1 with the Red wire to pin 1 and is wired to the ID Expander.
One ID Expander onboard the control panel PCB and one ID Expander remote
from the PCB.
The first module is plugged across the molex pins on the control panel PCB marked as
EXP1 and EXP2. The second module is then wired to the first.
