7. DISABLEMENTS

7.1 REASONS FOR DISABLING CERTAIN PARTS OF A FIRE ALARM SYSTEM.

Certain parts of this Fire Alarm Panel can be temporarily disabled (i.e. switched off) to suit prevailing conditions. For
example, if there is a risk of a False Alarm in a zone, for example, from vehicle exhaust smoke in a loading bay, it is
possible for the user to disable that zone during the risk period and then enable it again afterwards. During a disablement
of a zone(s), no fire or fault signal will be processed for that zone(s). Only zone(s) in a non-alarm state can be disabled,
that is zones already in fire cannot be disabled.
External sounders can also be disabled as could be required in certain conditions.
7.2 TO DISABLE A ZONE AND/OR EXTERNAL SOUNDERS.
1. Turn control key to "Controls Enable" position;
2. Press "Engineer" switch momentarily, this will cause General Disablement LED to flash (fast). This means the
panel is in disable/enable mode;
3. Press scroll (No. 4) switch once and this will cause the General Disablement LED to flash (slow);
4. Press scroll (No. 4) switch once again and this will cause Zone 1 Disablement LED to light steady;

General Disablement LED flashing slow, pressing "Engineer" will cause General Disablement LED light to change

7. Switch controls key to off position, then both the disabled Zone Disablement LED and the General Disablement
LED will remain lit (steady.
7.3 TO ENABLE A ZONE AND/OR EXTERNAL SOUNDERS.

3. Press scroll (No. 4) switch until the light is steady at the disabled zone;
4. Press "Engineer" and this will cause the General Disablement LED to flash (slow);
