Maintenance
The smoke detector system does not require any maintenance.
From time to time, remove the dust from the cover of the detector
and ensure that the air slots are not dirty or blocked up by insects or
similar objects. If necessary, the detector should be wiped off with
a dry cloth and then hoovered on the outside approx. twice a year.
Please observe the operating instructions of the device
manufacturer.

Changing the battery
To ensure that the block battery continues to function correctly it
must be changed regularly, but no later than when the warning signal
beeps.
• Carefully turn the cover of the smoke detector anti-clockwise until
it can be removed from its mount.
• Take out the used block battery and unpin it from the pins.
• Connect the new block battery to the pins, ensuring that the pins
click into place on the poles of the block battery.
• Place the battery in the smoke detector's battery container.
• Place the cover of the smoke detector so that the holes for the
lock are over the locking pegs. Carefully turn the cover clockwise
until it locks into the mount.

Test
• Press the test button for at least 4 seconds until the alarm goes
off. The alarm goes off when the electronic system is working. It
will stop as soon as you let go of the test button.
Test the smoke detector every time the battery has been
changed.
Batteries should never be thrown in the container for
normal household waste. Always return used batteries
to a shop that sells batteries or take them to a desi-
gnated collection point.
