Figure 5: Mounting on concrete
Always use a DV1202A mounting plate. The expansion plug must
penetrate at least 50 mm into the concrete. Please follow the steps
shown in Figure 6 if you are installing the test transmitter DV1215A.
$
For the equipment to conform to CEI standard 79-2, the
DV1215A test transmitter must be installed.
Figure 6: Control and function test
Using a voltmeter, check the background signal level in the detector
to prevent nuisance alarms. Set the sensitivity to Gmax during the
test.
