Manual disabling of the detector
It is possible to disable the detector for a 15 min period:
• prior to activities likely to generate abnormal heat (sudden rise in temperature or rise in room
temperature of above 54°C, e.g. during DIY work), and cause unwanted alarm activation,
• to stop the alarm when the heat generated is not dangerous (e.g. sudden sunshine), (only
possible with the detector having detected the rise in temperature and which can be
recognised owing to the flashing of its red LED).
In order to disable the detector, press the test button until the 1
st
beep sounds or until the
detector stops its built-in audible alarm. The LED indicating
the status of the detector flashes every 2 sec.
Battery fault indication
technical fault indication
To prevent users from being
disturbed at inconvenient times,
audible indications of a battery
fault or technical fault can be
delayed for 8 hours over a
maximum period of 7 days by
holding the test button pressed
until the first beep sounds. You
should contact your installation
engineer within this same period
in order to rectify the problem.
Following the 15 min disable
period, the detector is
automatically reset to normal
operation and its indication
LED flashes every 10 sec.
in order not to wake you up,
audible indications of a battery
fault or a technical fault are shut
down during the night. Any faults
are reported either after
daybreak for a period of over
10 min or 12 hours after their
occurrence.
During this 15 min. period,
the detector will be unable to
recognise heat or generate
alarms.
