2.5.4
Connecting the tamper switch (6)
Where necessary, the
external
tamper monitoring function of the Compact Reader can be
connected. As soon as the PCB (in the housing) is lifted off the mounting plate plug, this
interruption to the connection (e.g., at the input of the parent control unit) can be evaluated as
sabotage. When closed, terminals 6 and 9 are connected to the PCB via a 680 ohm resistor.
