Manual suppression of signals
8.1
Suppressing the smoke detection alarm
Smoke detection can be deactivated for 15 minutes:
• as a preventative measure to suppress an unwanted alarm when
carrying out activities that generate dust (sweeping a dusty room,
sweeping the chimney, etc.),
• to shut off the alarm if you detect non-hazardous smoke.
To do this, press the function button briefly (< 3 seconds) until a short
acknowledgement signal is heard and then muted again. The light ring
now flashes every 2 seconds
Note
Thermal detection is still active.
8.2
Suppressing the event display
A photovoltaic cell is used to suppress the "Detection head dirty" and
"Battery change due" warnings (Section 4) for up to 12 h during hours of
darkness. This has no influence on the alarm functionality provided by
the smoke detector.
If the "Replace battery" or "Fault/soiling" message occurs at an
inopportune time, it can be deferred by 8 hours each day for a maximum
of 7 days. To do this, press the function button briefly, until the first signal
tone is muted.
However, remove the source of the fault as soon as possible.
Please contact your installer to rectify cause of the problem.
