Care and maintenance, Manufacture date
· Do not use flammable liquids for cleaning the alarm!
Maintenance
· The electrochemical sensor is subject to ageing. The sensor lifespan is
thereby limited to 10 years.
· The sensor cannot be exchanged. For this reason, replace the entire
device 10 years after the date of its installation at the latest. (See label
on the rear side of the alarm).
