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 a fire condition cannot be disabled.
External sounders can also be disabled as could be required in certain conditions.
