To verify the correct operation of the
detector, test gas can be used which is
equivalent to the alarm thresholds. Test
kits are available.
1. Fit pressure regulator on to calibrated gas bottle and check the
cylinder pressure is above 10 bar.
The test gas cylinder should be stored at room temperature or
allowed to stand at room temperature for at least 4 hours prior to
use.
Ensure the detector is powered up for a minimum of 1 hour before
testing.
