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 first switched on in the listen mode. The operator can control the direction of
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 90 seconds, the module will disconnect from the phone line.

ANNUNCIATION OF ALARM
The Voice Alarm Module enables the system to speak the type of alarm and zone over a speaker on premises. When an alarm first
occurs, the siren is activated. After a few seconds, the siren is turned off and the type of alarm is announced. The siren is then
reactivated. After a few seconds, the siren is again turned off and the violated zone is announced. The siren is then reactivated. This
process is repeated until the alarm is disarmed or reset.
Note: During central station communication (while the system is reporting an alarm to the central station), voice alarm notifications
are temporarily suspended. After the successful transmission of the alarm to the central station, voice alarm notifications are restarted.
SPEAKER VOLUME CONTROL
The volume of the audio can be controlled by adjusting a variable resistor on the module. Use a small screwdriver to adjust R35
labeled “Speaker Volume”. Do not adjust R59 labeled “Audio Cancel”. This variable resistor it is adjusted at the factory to its
optimal setting.
