Troubleshooting:
Do not remove the batteries to stop an unwanted alarm. This will reduce your security.
Remove smoke or dust by opening ventilation ducts or windows.
Problem
No alarm sound is heard during the test.
The sensor beeps every 40 seconds and
the red LED light flashes.
The alarm sounds different than before, it
sounds and goes silent then.
Recommended Places for Installation:
First you need to install in your bed-
room and the corridor leading to the
bedroom. If there is more than one
bedroom, it is recommended to place
sensors in each bedroom.
Install sensors on stairs and on each
floor.
Smoke, heat and burning particles will
move horizontally after rising towards
the ceiling. It is therefore recommend-
ed to install the sensor in the centre of
the ceiling. Make sure the sensor covers
every corner..
Solution
• Check if the batteries are placed correctly.
• Replace the sensor.
You need to replace the battery. Refer to the
"Battery" section.
• The alarm is working correctly.
• Cleanthesensor (refer to"Maintenance and
Cleaning").
If the sensor cannot be installed in the
centre of the ceiling for any reason, try
to install it 50cm away from the walls
(see FIGURE 1).
If the length of the room or corridor is
longer than 9 meters, it is recommend-
ed to install more t an one alarm.
If the ceiling is sloped, the alarm should
be installed at least 50 cm away from
the highest point of the ceiling (See
FIGURE 2 and 3).
