• Smoke alarms should be positioned on the ceiling, in the middle of a room, or on
the hallway and landing. If bedrooms are scattered throughout your home, several
smoke alarms should be used.
• Fit at least one smoke alarm on every level of your home. The more smoke alarms
you have – the safer you’ll be. Make sure that you can hear the smoke alarms from
your bedroom.
• Smoke alarms should normally not be more than 10–12 m apart.
The maximum floor space area that one smoke alarm can protect is 60 m².
• Don’t put alarms in or near kitchens or garages where smoke or exhaust fumes
can set them off by accident. Neither is it advisable to fit smoke alarms in bath-
rooms or close to fans.
Note: A smoke alarm must not be painted over.
3. Radio signal reliability
Every building has its own unique radio transmission characteristics and the wireless
signal transmission of your alarms can change over time depending on various factors
so we cannot guarantee the range of the range of the radio signals. The operation and
range of the alarms should be checked regularly to ensure that they can be heard from
your bedroom.
4. Setting the radio signal code
If you wish to interconnect several alarms into a system, all the alarms
need to be set to the same code. When sold, all the smoke alarms
are set to code 1 by default. We therefore recommend that you
change the code whenever installing a system. The same rule
applies if by some chance you should happen to have a false alarm
because your neighbour’s smoke alarm is set to the same code
(or code 0, as explained below). Whenever you have changed
the code of your smoke alarm system, you should check to make sure that they work
(refer to Test and maintenance).
Special functions for code 0
When a smoke alarm is set to code 0, it can be set off by any alarm no matter which
code the other alarm is set to after a delay of 3 minutes, i.e. if another alarm goes off
for longer than 3 minutes, even an alarm set to code 0 will go off. This special function
can be utilized in corridors or stairways to safeguard communal escape routes for
several apartments.
If a smoke alarm set to code 0 goes off, it has priority and sets off any other alarms no
matter which codes they are set to. This function can be used for stairways, children’s
bedrooms and other areas of a house.
