Care and maintenance
Dusty detectors must be cleaned. You can clean dust from
the air vents of the detector using a vacuum cleaner or
compressed air.
If necessary, you can remove the dust with a brush.
You can clean the surface using a cloth slightly dampened
in soapy water.
Do not allow water to enter the inside of the device. Do not
clean the device in a dishwasher.
Do not use sharp, pointed, abrasive or corrosive cleaning
materials, chemicals or hard brushes.
The electronic components of every smoke alarm device
are subject to ageing processes. In addition, the insect
protection grid and smoke measurement chamber will
inevitably become soiled over time.
In order to guarantee the full functionality of the smoke
alarm devices, they must be exchanged 10 years after
installation at the latest.
