Testing, monitoring and maintenance
Your smoke alarm is a life saving device and should be checked periodically. Regularly
check that the red light on the smoke alarm blinks approximately every 45 s to show
the units are powered. Replace the battery if the blinking stops.
Manually testing your smoke alarms
It is recommended that you test your smoke alarms after installation and then at least
weekly to ensure the units are working. It will also help you and your family to become
familiar with the sound of the alarms.
Press and hold the test button until the alarm sounds and the red light blinks (see
Figure 6 on page 15). The alarm will stop sounding shortly after the button is released.
If the smoke alarm has a wireless connection to a supplementary Visit receiver, check
that the green light on the cover of the smoke alarm starts to blink and that the Visit
receiver reacts. See the Quick start guide on page 6 and the Visit receiver user manual.
Release the test button. The smoke alarm and Visit receiver will stop signaling within 40 s.
Repeat this procedure for all other smoke alarms in the system.
WARNING: Do not test with ame.
This can set re to the smoke alarm and damage the house. We do not recommend
testing with smoke as the results can be misleading unless special apparatus is used.
When you press the test button it simulates the eect of smoke in a smoke alarm which it
could experience in a real re. So, there is no need to test smoke alarms with smoke or ame.

Test/hush button to control nuisance alarms
The smoke alarms have a combined test/hush button to help you control nuisance/
false alarms.
If, when the alarm sounds, there is no sign of smoke or noise to indicate that there is
a re, it should be assumed that it is due to an actual re and the dwelling should be
evacuated immediately.
Check the house carefully in case there is a small re smoldering somewhere.
Check whether there is some source of smoke or fumes, for example cooking fumes
being drawn past the smoke alarm by an extractor.
If there are frequent nuisance/false alarms it may be necessary to re-locate the smoke
alarm away from the source of the fumes.
1 To cancel a false alarm from a smoke alarm (which has its red light blinking rapidly),
press the test/hush button (the smoke alarm will automatically switch to a reduced
sensitivity condition). The smoke alarms will be silenced for a period of approximately
10 minutes. The red and green light on the cover of the smoke alarm will blink every
8 s (instead of 45 s) to indicate that the unit has been silenced.
2 The smoke alarm will reset to normal sensitivity at the end of the silenced period (10
minutes). If additional silenced time is required, simply push the test/hush button again.
3 If kitchen usage/layout is such that there are an unacceptable level of nuisance
alarms, re-locate the smoke alarm further away where it will be less aected by
cooking fumes etc.
We recommend the use of a heat alarm in the kitchen area to avoid such nuisance alarms.
