1. Listen mode is used to listen to the premises from an
inside, remote, or central station telephone. You cannot
talk to anyone on premises in listen mode. Whenever
the module is switched on, it is set to the listen mode.
2. Talk mode is used to talk to someone on-premises from
an inside, remote, or central station telephone. You
cannot listen to the premises while in the talk mode.
The mode can be changed between listen and talk by using
the keys on a phone. When the module is switched on, a
90 second disconnect timer is started. If no tones are
detected within 90 seconds, the module will be switched
off. Each time a tone is received, the timer is reset.
CENTRAL STATION OPERATION
When an alarm occurs, the communicator first sends the
appropriate report to the central station. After the
transmission of the alarm to the central station, the operator
can talk and listen to people and sounds at the premises.
After the report is received by the central station operator,
the Two-Way Audio Module is switched on. The central
station operator can now listen to the premises. The
module is always switched on in the listen mode. The
operator can control the direction on the communication by
using the Touch-Tones on a telephone. Each time the
operator switches between the listen and the talk mode, a
short tone will sound over the audio speaker at the
subscriber's premises. This alerts the subscriber that the
operator has switched communication mode. If no tones
are detected within the 90 second disconnect period, the
module will disconnect from the phone line.
