11 Maintenance

The Searchzone Sonik detector should periodically be inspected, cleaned and tested. The required frequency of inspection will depend
on the hazardous area risk and maintenance plan. Please refer to IEC/EN 60079-29-2 or other local or national regulations for
guidance on establishing an appropriate maintenance routine.
The detector requires little maintenance other than occasional cleaning. Depending on the local regulations and site conditions,
cleaning and functional testing of the detector can be carried as described in the following sub-sections. The detector should remain
powered during these procedures.
CAUTION
The Searchzone Sonik does not contain any user serviceable parts. Do not open the main enclosure.
Doing so will invalidate the warranty.
CAUTION
Seek authorized service in case of detector failure or malfunction.
Note
The Searchzone Sonik detector requires no calibration. Periodically perform a proof test on the detector.
11.1 Inspection and Cleaning
CAUTION
Do not use solvents or abrasives on the Searchzone Sonik unit.
1) Inspect the Searchzone Sonik unit and cabling for signs of physical damage.
2) Clean any dust or dirt from the Searchzone Sonik unit using soapy water and a soft cloth.
11.2 Periodic Proof Test using a Canister of Compressed Air
Using a mobile device running the Searchzone Sonik App, connect to the Searchzone Sonik detector. If required, place the detector into
an inhibit state.
Obtain a full canister of compressed air.
Stand directly in front of the Searchzone Sonik detector at a distance of no greater than 5 m (16.4 ft).
Depress the nozzle of the compressed air canister to open the valve. Check that the Searchzone Sonik detector responds accordingly.
Note that as the nozzle cools due to the release of compressed air, the characteristics of the ultrasonic noise produced will change
significantly. Always allow sufficient time for the nozzle to return to normal temperature before repeating any tests.
If the Searchzone Sonik detector was placed in an inhibit condition for the test, use the Searchzone Sonik App to return the detector to
normal operation.
11.3 Suggested Maintenance Schedule
The maintenance schedule will reflect local working environment and should be agreed with Honeywell representatives prior to
commissioning the Searchzone Sonik.
