Disablement condition
A disablement condition is the manual or automatic disablement of a part of the fire detection system. An
automatic disablement may be pre-configured for your premises to disable smoke sensors, in areas where
smoke may be present for example during the normal working hours. Also a disablement may be necessary
where building work is being undertaken that could result in a false alarm.
CAUTION: Any changes to
the setting of an automatic
disablement must only be
attempted by a trained
engineer who is
responsible for the fire
alarm system, see contact
details in the Log book.
What must be done?
Investigate the reason for the disablement and re-enable if appropriate.
Record the event
Where necessary make an entry in the log book of the event for future
reference.
