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.

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.
