4.0 Connections
4.1 Cabinet Enclosure Tamper Switch
The cabinet enclosure tamper input signals to the monitoring station or remote computer that an
cabinet enclosure has been opened. The tamper input switch should be mounted into the steel
bracket provided and connected to the tamper connection terminals
as shown in
figure 1
below.
4.2 Earth Ground Connection
The Protégé® SE Integrated System Controller has a connection for earth ground. For best
results a
cold water pipe should be used with a pipe wiring clamp. If a cold water pipe is not available
connect to a suitable ground connection in the installation. A minimum 14AWG solid copper wire
should be used from the Protégé® SE Integrated System Controller’s earth connection point to the
clamp on the cold water pipe. If other earth clamps are present at the same connection point
connect the clamp below the existing units.

The telephone communication dialer contains a separate earth connection. Do not
loop the earth connection from the dialer to the earth of the Protégé® SE
Integrated System Controller. A separate connection should be connected to the
same earth point.
