External tampers connection
The Jumper P1 present on Multi is designed to connect an external
tampers for the device (not provided).
Such tamper could be used as anti removal tamper for the device or to
connect the anti open tamper of an external case who hosts the Multi
device.
From factory, and when external tamper is not used, P1 is closed with
a jumper.

Figure 25 - External tamper connection schema
Please note that:
P1 and the device anti-open tamper 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.
