Listen-in
A menu option that sends a report to the central station indicating that a listen-in
session must be started.
Listen-in is a user function. In order to use listen-in, a CS534 listen-in module must
be installed and a microphone must be connected. When an alarm is generated
and reported, the central station can listen to what is happening on the premises.
Certain protocols (such as SIA, Contact ID and 200Bd FSK) have ‘listen-in blocks’
that are communicated with the alarm code and indicate that a listen-in session
must be started.
