ENGLISH
Please observe that DGS works as a safety device securing a
reaction to a detected high gas concentration. If a leakage
occurs, the DGS will provide alarm functions, but it will not
solve or take care of the leakage root cause itself.
Regular Test
To maintain product performance and comply with the local
requirements the DGS must be tested regularly.
DGS's are provided with a test button that may be activated to
validate the alarm reactions.
Additionally the sensors must be tested by either bump test or
calibration.
Danfoss recommends the following minimum calibration intervals:
DGS-IR: 60 months
DGS-SC: 12 months
DGS-PE: 6 months
With DGS-IR it is recommended to do an annual bump test in years
without calibration.
Check local regulations on calibration or testing requirements.
After exposure to a substantial gas leak, the sensor should be
checked by bump test or calibration and replaced if necessary.
Location:
For all gas’ heavier than air, Danfoss recommends locating the
sensor head app. 30cm (12") above the floor and if possible in the
air flow. All gas’ measured with these DGS-sensors are heavier than
air: HFC grp 1, HFC grp 2, HFC grp 3, CO2 and Propane.

Detection application guide, DKRCI.PA.S00.A-.02
