Encryption Key Administration
The intercom can keep up to 4 valid encryption keys: 1 primary and up to 3 secondary
ones. A mobile device can use any of the 4 keys for communication encryption. The
encryption keys are fully controlled by the system administrator. It is recommended
that the encryption keys should be periodically updated for security reasons,
especially in the event of a mobile device loss or intercom configuration leak.
