Planning and Installation manual VV600/VV602Plus
27
Give one powerful blow near the detector with a hammer. Both VV600Plus and
VV602Plus should give an alarm immediately. This test simulates an attack with
explosives.
Check up the background signal level in the detector to prevent nuisance alarm.
Connect a DC volt-meter, internal resistance 20 KOhm/V or more, to terminal 2
(negative) and terminal 4 (positive). Place the volt-meter in the range around 3 V.
Put the sensitivity selector in the maximum sensitivity Gmax. Make sure that all
possible causes for vibrations in the protected area are present and operating.
Check the output voltage and take measures accordingly.

Preferably, you should try to remove the source of ambient noise instead of
reducing the range.

Do not forget to set the detector’s sensibility at the right value. Close
the lid of the detector and check for closed-loop condition of the
tamper-loop. Perform a functional test of both alarm and tamper
signals according to panel specifications.
