In order to ensure the operational reliability of the detector, testing
should be carried out at least once a year.
Testing can be carried out every month, without endangering the
prospected battery life of 10 years.
Proceed as follows:
1.
Remove dust from the detector with a soft cloth if necessary
2.
Remove dirt with a damp cloth if necessary. Do not use cleaning
agents.
3. Visual check:
Are the air apertures clear?
Is the combined detector damaged?
Is there free open space of > 0,5 m around the detector?
Has the purpose/usetype of the room been changed?
4. Carry out a test by pressing the test button.
