9. ZONE DISABLEMENT
The Premier AD is designed to operate as a zone based panel. You can therefore
only disable a whole zone. It is not possible to disable individual devices.
9.1 WHY USE ZONE DISABLEMENT
To aid commissioning and assist routine maintenance checks, any of the zones or the sounder
circuits can be disabled.
When a zone (or sounder cct) is disabled, the panel will not respond to any fault or fire signals it
receives from that zone*. This might be used if the system requires routine maintenance, and the
customer needs the system to continue running, but doesn’t want spurious false alarms.
The panel will respond in the usual manner to any events in any non-disabled zones.
The premier AD allows the 4 conventional sounder circuits to be disabled individually, and
also allows the loop powered sounders to be disabled
9.2 TO PROGRAMME ZONE (OR SOUNDERS) AS DISABLED
Any number of zones (or the sounders) can be disabled, but it is good practice to only disable one
zone at a time.
1. Insert and turn control key to enabled position;
2. Press DISABLE button and the ZONE 1 DISABLED LED will flash (The panel is now in
SELECT DISABLEMENT MODE)
3. Press DISABLEMENT SELECT until the required zone or sounder circuit is lit. Press
DISABLEMENT CONFIRM button, and the LED will come on steady, along with the GENERAL
DISABLEMENT LED This section is now disabled*.
4. If more than one zone (or sounder) needs to be disabled, then press DISABLEMENT SELECT
again until the required zone (or sounder) is selected.
5. If the panel needs to be taken out of SELECT DISABLEMENT MODE (eg to silence a fault on
another part of the system), turn the keyswitch off, then back on again.
6. Once all the work has been done the zones need to be enabled again. If the panel is still in
SELECT DISABLEMENT MODE, jump to paragraph 7, otherwise, turn the keyswitch to
controls enabled, press DISABLE button. The panel is now in SELECT DISABLEMENT MODE
7. Press the DISABLEMENT SELECT button until the disabled zone has been selected. Press
DISABLEMENT CONFIRM button to de-select disablement. Scroll to any other disabled zone
and enable in the same way. When all zones are enabled again, the GENERAL
DISABLEMENT LED will turn off. Turn the keyswitch to off position to return the system to
normal.
*To enable the system to be functional in the event of a real fire during
maintenance, the manual call points remain active, even if the zone they are in
has been disabled
