Maintenance and servicing
Cleaning
If necessary, clean the exterior of the enclosure with a damp cloth. Do not use alcohol or ammonia-based
liquids to clean the detector.
Servicing
We recommend the user to periodically inspect the proper triggering of alarm and fault relays, the buzzer
and indications on the front panel of the controller. Test must be done by applying etalone gas mixture to
the gas detectors.
The adjustment operations of the gas detection system must be done only by authorized, trained
personnel because they may compromise gas detection system reliability.
Servicing frequency
Zeta Alarms Ltd, recommends regular testing of fixed gas detection installations. The type of test consists
of injecting a standard gas mixture of sufficient concentration into the detector to set off the preadjusted
alarms. This test does not, replace a full calibration of the detector. Frequency of the gas testing depends
on the industrial application in which the detectors are used. Inspection should be done frequently the
first months after installation starts up, later it may be spaced out if no problem is observed.
If a detector does not react upon contact with gas, it must be calibrated. The frequency of calibration will
depend on tests (humidity, temperature, dust, etc.); calibration should occur at least once every year. We
also recommend calibrating the detector after exposure to high gas concentrations. The site manager is
responsible for implementing the safety procedures on site. Zeta Alarms Ltd is not responsible for
implementing safety procedures.
