12 Maintenance and service

In some German Federal lands, the state construction ordi-
nance states that the property owners are responsible for the
installation and functionality of smoke alarm devices. In the
remaining German Federal lands, the responsible operator
must carry out maintenance.
Recommended maintenance interval
Carry out maintenance at least once annually. Compliant with
DIN 14676, maintenance includes a visual inspection and a
functional test / alarm test. You must carry out a functional
test after a longer period of absence, or after one year at the
latest.
