5.2.4. TWA Follow-Me
The TWA Follow-Me feature is designed to establish a Two-Way Audio connection with the user in the event of an
alarm. For this feature to function, the account's protocol must be defined as TWA Follow-Me.
The sequence for a Two-Way Audio Follow-Me call is as follows:
1. An alarm occurs.
2. The Control System dials the programmed telephone number and sounds two DTMF tones when you pick up the
call.
3. Press "2" on your telephone; the Control System opens the audio channel.
If you press "9" to answer the call, the Control System simultaneously cancels the siren when
opening the audio channel.
4. If the TWA mode is defined as "Simplex", (see p. 60, 10.6.11 TWA Mode), the audio channel opens in Listen mode
(microphone active/speaker mute). To switch to Speak mode, press "1" on your telephone. To switch back to
Listen mode, press "0" on your telephone.
5. The duration of the call is determined by the TC/VM Timeout. Ten seconds before the timeout expires, two short
DTMF tones are sounded. To extend the call, press "7" on your telephone. This command restarts the
timeout.
6. To disconnect before the end of the timeout, press " " then "#" on your telephone.
