6.2 NON LATCHING ZONES
The optima panel has the option to configure zone 1 as a non-latching zone. This is done by snipping
the jumper link SW1 with a small wire cutter WHEN THERE IS NO POWER APPLIED TO THE
PANEL.
When zone 1 is configured as non-latching, the panel will start the sounders & light zone 1 Fire LED
on receiving an alarm signal, but it will not activate its fire relay. When the alarm signal is removed,
the panel will automatically reset itself.
The main use for using non latching zones is for linking 2 or more fire alarm panels.
7. ZONE DISABLEMENT
7.1 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 circuit) 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.
7.2 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 Engineer switch and the GENERAL DISABLEMENT LED will come on (flashing fast);
3.
Press Scroll switch and the GENERAL DISABLEMENT LED will flash slowly. The panel is now
in SELECT DISABLEMENT MODE.
4.
Press scroll button again. Zone 1 DISABLEMENT LED will be lit. Continue to press scroll until
the desired Zone or sounder is lit. Press the Engineer button. The GENERAL DISABLEMENT
LED will be lit constantly indicating that this zone (or sounder) is now disabled.
5.
If more than one zone needs to be disabled, then press scroll again until the required zone is
selected.
6.
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.
7.
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 8, otherwise, turn the keyswitch to
controls enabled, press engineer button (GENERAL DISABLEMENT LED will flash fast). Press
scroll and it will return to being on steady. The panel is now in SELECT DISABLEMENT MODE
8.
Press the scroll button until the disabled zone has been selected. Press engineer button.
Scroll to any other disabled zone and enable in the same way. When all zones are enabled
again, the GENERAL DISABLEMENT LED will flash slowly. Turn the keyswitch to off to return
the system to normal.
