It is possible to disable the detector for a 15 min period:
• prior to activities likely to generate abnormal heat (fast rise in
temperature or increase in room temperature above 54°C,
e.g. during DIY work) and hence cause untimely triggering
of the alarm,
• to stop alarm sounding if non-dangerous heat is detected
(e.g. sudden sunshine), (only possible with the detector
having triggered the heat signal and which can be
recognised by its flashing red LED).
In order to disable the detector, press the test button until the
1st beep sounds or until the detector stops its built-in
sounding.
The LED indicating the status of the detector flashes every
2 sec.
Following the 15 min disable period, the detector is
automatically reset to normal operation with the detector
status LED flashing every 10 sec.
