Mounting the detectors
Mounting the detector directly on a metal surface without
using a mounting plate
See Figure 4.
Mounting the detector on a metal surface using the
VM604P weld-on plate
See Figure 5.
First weld points 1, 2, 3, and 4. Then weld seams 5 and 6.
Mounting on concrete
See Figure 6.
Always use a VM600P 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 VT705P.
Note: For the equipment to conform to CEI standard 79-2,
the VT705P test transmitter must be installed.
Testing the seismic detectors

Test disabled (ex-factory setting)
Internal test of detector’s electronics = Position jumper between
1 and 2.
Functional test of the detector and its physical contact with the
protected object: Position connector from test transmitter
VT705P between 2 and 3.
Note: Connecting terminal 10 to 0 V activates both tests.
Control and function test
See Figure 7.
Using a voltmeter, check the background signal level in the
detector to prevent nuisance alarms. Set the sensitivity to Gref
during the test.
Reduce range/remove source
Note: Try to remove the source of ambient noise instead of
reducing the range.
Functional testing with hand tester VT610P (item 1) and
mechanical tool (item 2):
