shall be supervised by the system. The system shall supervise the signal
lines by monitoring changes in the direct current that flows through the
signal lines and a terminating resistor. The system shall initiate an
alarm in response to a current change of [5] [10] percent or greater. The
system shall also initiate an alarm in response to opening, closing,
shorting, or grounding of the signal and DTS lines.

Data Encryption
**************************************************************************
NOTE: Data encryption should be used only when
required by governing regulations or when it has
been determined that it is undesirable to allow
unauthorized persons access to system
intercommunication.
**************************************************************************
The intrusion detection system shall incorporate data encryption equipment
on data transmission media links as shown. The algorithm used for
encryption shall be the Data Encryption Standard (DES) algorithm described
in ANSI INCITS 92.
