Zone Expander (ZEX) Wiring Modes
Three wiring modes may be programmed for each ZEX these are.
4 Wire Gives 4 zones AZE 1 - AZE 4 and four tampers TZE 1 - TZE 4
2 Wire Gives 8 zones AZE1 - AZE 4 then TZE 1 - TZE 4
End Of Line Gives 8 End Of Line zones AZE 1 - AZE 4 then TZE 1 - TZE 4
All AZE zones are positive loops and all TZE zones are negative loops. when using 2
wire mode please reserve one positive and one negative zone for your tampers.
Tampers should be opposite polarity to the zone being protected.
Before powering up place jumper ZEX on position 1 to 4 (5 - 16, 601).
For the purpose of allocating expander zones the control panel should be viewed as
unit number 1 and the first expander card as unit number 2 all zones on expander
number 1 therefore start with 2 (e.g 21, 22, 23 . ...)and all zones on the second
expander that is unit number 3 start with 3 (e.g 31, 32, 33 . ...)

From Control Panel to Zone Expander Card 100m maximum
From Zone Expander Card to last Device 100m maximum
On long wiring runs do not draw power for detectors from the Zone Expander Card,
use a separate Power Supply for the detectors.
