Maintenance
• 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 function of the smoke alarm
devices, they must be exchanged every 10 years at the
latest.
