Note:
If exit terminator is required program zone as ET
If unset doorbell is required allocate chime to the
ET zone.
Exit terminator zone must be AZ zone
Setting Mode should be programmed for ET
Note:
AZ zones are +ve
TZ zones are -ve
To comply with BS4737 alarm and tamper loops
should be oposite polarity
Any unused zones may be programmed to off
and the factory fitted link can be removed from the
zone terminals.
It is not advisable to connect normally open devices
onto a TZ loop
Normally Closed Tamper Contacts
for all TZ zones (9-15)
Normally Close Tamper Contacts
for all AZ zones (1-7)

(control panel 2 Wire option)
The second wiring method is Two Wire. This option will give sixteen zones available
from the control panel PCB.
To use the 2 wire option the control panel should be programmed for
16 (2 WIRE) in the programming section 'PROGRAM ZONE WIRING' (option
No.50)
When this wiring option is programmed zones AZ1 to AZ8 are zones 1 to 8 inclusive,
all AZ zones are positive loops.
Because the 2 wire option has been selected the TZ terminals are also programmable
as zones. The zone numbering for the TZ zones will be as follows:-
Zone 9 on terminals TZ1
Zone 10 on terminals TZ2
Zone 11 on terminals TZ3
Zone 12 on terminals TZ4
Zone 13 on terminals TZ5
Zone 14 on terminals TZ6
Zone 15 on terminals TZ7
Zone 16 on terminals TZ8
It should be noted that in order to comply with the requirements of BS 4737 zones and
tampers should be of opposite polarity. This means that when using the 2 wire wiring
option one AZ zone (e.g zone 8, AZ8) should be programmed as 24Hr and used as a
global tamper for all TZ zones, and one TZ zone (e.g zone 16, TZ8) should be
programmed as 24Hr and used as a global tamper for all the AZ zones.
Typical wiring of various detectors is given in Fig.24
