6.3: Two-Way Audio after an Alarm

In the event of Burglary, Fire and Medical alarms, the control panel is able to report the
events and then stay on the line. This allows the monitoring service to verify the alarm or
provide assistance in the event of an emergency.

6.4: Two-Way Audio Follow-Me

This feature causes the control panel to call you in the event of an alarm so that you may
check your family and home.
When the control panel calls, you will hear two short tones when you pick up the phone.
Press any key on your telephone to answer the call.
If you press 9 to answer the call, the control panel simultaneously cancels the siren when

6.5: Simplex Mode

It is possible that the Two-Way Audio features on your system are programmed to
operate in "Simplex" mode. Simplex mode means that one party may speak while the
other party listens.
If using Simplex mode, the call is connected in Listen mode. In Listen mode, the
microphone on the control panel is turned on so that you can listen in. If you want to
switch to Speak mode, press 1 on your telephone.
In Speak mode, the microphone is turned off and the speaker is turned on so that you
can speak to the person on the other end of the line. If you want to switch back to Listen
mode, press 0 on your telephone.
