System Overview
Zone Allocation to Areas
Whilst within the zone programming section zones may be allocated to areas. This
may be one single area or multiple (common) areas.
If a zone is allocated to more than one area it is then a common area zone
and the following logic is applied:-
If any area that is assigned to the zone is unset then the zone is not active.
If all areas that are assigned to a zone are set then the zone is active.
If any area that is assigned to the zone is in exit then the zone is also in exit
(zone type will still apply).
If any area that is assigned to the zone is in entry then the zone is also in
entry (zone type will still apply).
Zones
The control panel is supplied with 8 four wire zones (two wires for zone & two wires for
tamper).
If required this configuration may be programmed for 16 two wire zones. In this case,
two zones should be reserved for global tampers and the remaining 14 zones are then
programmable for the desired zone types.
The control panel zones may also be programmed as 16 EOL (End Of Line resistor)
zones. This configuration gives the highest possible zone wiring security and a
maximum of ten detectors may be wired on to each zone when this option is selected.
Resistors required for EOL operation are supplied with the control panel.
When using EOL zones each detector has a 6K8 resistor in parallel with the alarm
contacts and there is a 4K7 resistor in series with the two zone wires. This gives both
alarm and tamper protection from a single pair of wires. To make full use of this
security feature the 4K7 resistor must be fitted to the furthest most point in the loop.

Zone Expansion
An expansion path is available through zone expander boards. Each expander board
being programmable for 4 x four wire zones, 8 x two wire zones or 8x two wire EOL
zones. Up to eight expander boards may be fitted to a Gardtec 840
eighty zones when configured as 2 wire or 2 wire EOL zones, and up to two expander
boards on the 816 giving a maximum of 32 zones. Each expander board and the
control panel zones may use differing wiring configurations.
Expander cards may be fitted in locations away from the master control panel.
More details of zone options are given in the relevant sections in this manual.
ID Zone Expansion
As an alternative to ZEX expansion up to two ID expander boards may be fitted. Each
ID expander board will accept up to 30 standard ID biscuits/devices. ID biscuits may
be used with all standard detection devices. This system allows either single leg or ring
wiring using standard alarm cable, detectors may, if required be 'teed' of the leg or
ring. This expansion method can offer considerable savings of cable and labour
One ID expander card may be plugged on to the control panel PCB (not with onboard
RKP) with the other remote. Alternatively both ID expander may be mounted remote
from the control panel.
Zone Descriptions
Up to sixteen characters may be used for zone descriptions on the LCD keypad. The
description that you allocate to a zone will also be applied to the tamper of that zone. If
the cause of an alarm is through a zone tamper the description will be shortened to 13
characters on the display, the last three characters being replaced with <space>T!
The zone descriptor is displayed whilst viewing the cause of an alarm, viewing the log,
if a zone is violated during exit and when programming zone descriptors
User Names
Each user (with the exception of the engineer) may be allocated a user name of up to
nine characters. This name will be shown if the system is being set with a master or
main code type and whilst viewing the log.
