7 Operation / Maintenance

In case of dirt, the surface can be cleaned with a slightly damp cloth as required. The connected transmitters must be serviced
at regular intervals, in two ways:
Perform "calibration" and functional check once every 6 months - setting the sensitivity of the transmitter using a calibration
gas, checking the functionality of the system. The exact interval depends on the cleanliness of the environment, the required
accuracy, and the presence of interfering gases in the environment.
a) 1x in 12 months perform "calibration" - setting the sensitivity of the transmitter using the calibration gas, checking the
functionality of the system. The exact interval depends on the cleanliness of the environment, the required accuracy, and
the presence of interfering gases in the environment. In addition, a "functional check" must be performed once every 3
months - check the function of the entire detection system with a test gas that does not exceed the range of the
transmitter.
Substances for testing fire alarms must not be used for "functional inspection"!
Perform the calibration only in certified services with a valid certificate of competence or at the manufacturer.
For the Czech Republic, it is only DEGA CZ s.r.o.
