7. DISABLEMENTS
7.1 REASONS FOR DISABLING CERTAIN PARTS OF A FIRE ALARM SYSTEM.
Certain Fire Alarm Panels can be temporarily disabled (i.e. switch off) to suit prevailing conditions. For example, if there is
a risk of a False Alarm in a zone, say 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). A zone(s) in a non-alarm state can only be disabled, that is zones already in fire
cannot be disabled.
External sounders can also be disabled as could be required in certain conditions.
