As result of chemical wear of the sensor, the CO alarm
does not work properly after the service life of ten years
specified. Replace the device after ten years even if the
outer appearance does not indicate any signs of wear�
Avoid direct contact with vapours emanating from adhe-
sives, paints and cleaning agents to prevent the sensor
ageing or deteriorating more quickly�
