can use the below schematic.
Figure 20 – Single external tamper connection schema
Please note that:
J1 and J3, and so the two external tampers, are
in series and thus it is not possible to
distinguish which of the two tampers raised the
alarm. From the supervision center the two
tampers generate the same events.
