5. Commissioning and maintenance
Attention!
Service and maintenance activities for gas warning and detection systems have
to be done by trained and authorized personnel.
Record keeping has to be done for all service and maintenance activities.
Commissioning and maintenance of gas warning and detection systems has to be
done following the requirements of the european standards EN 60079-17, EN
60079-29-2 and/or EN 45544-4. Additional national regulations (e.g. german
„Merkblatt T023“ or „Merkblatt T021“ of BG RCI) and the manuals of the
connected detectors have to be observed.
At commissioning and in a regular interval (depending on connected detectors
and the industrial application), but minimum once a year, the following work
has to be done:

Inspection and adjustment of detectors according manuals (or more often)

Inspection of alarm triggering

Performance inspection of all relays contacts

Test of visual and acoustical warning signals of the detection system (for
functional test see chapter 3.4.2)

For inspection of alarm triggering following test gas concentrations are
needed:
- Monitoring of lower explosion limit (LEL), inerting and oxygen
enrichment: A test gas concentration maximum 10% above main alarm
level
- Monitoring of oxygen deficiency: A test gas concentration maximum
10% below the main alarm level
For safe and regular maintenance we provide you service contracts for your gas
detection system. With our skilled and trained service technicians we will give
you a high level of safety and confidence in your safety devices. Please contact:
