GARDTEC 800 Series
Zone Expander Cards
Two types of zone expander cards are available, the Gardtec 816 Expander Card that
may only be used on the 816 and the Gardtec 840 Expander that may be used on the
816/840.
Up to eight zone expander cards may be fitted to the Gardtec 840 and two on the 816
control panel. If required one of these expander cards may be plugged directly onto the
the main PCB, the other expander cards then being wired to the plug-on card as
shown in Fig. 30. Four cores are required for interconnection of the zone
expanders. If Output Expanders are to be used ( 840 only ) on the same leg as
zone expanders an extra core will be required.

The expander cards may also be wired back to the onboard expander card in 'Star'
format (each expander card wired back individually).
Alternatively all the zone expander cards may be wired to the main PCB via an
optional zone expander cable Part No. 01-094. If the 816 Expander Cards are being
used two expander cables will be required. When using the zone expander cable the
following colours should be used (see Figs 31a, 31b).
If Output expanders are used ( 840 only) all SAD 2 connections should be
interconnected. If the expanders are remote from the main PCB a second expander
cable will be required to plug onto PCB EXP2 socket. The SAD2 connection on this
second cable is the yellow core.
