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 panel dials the programmed telephone number and

sounds two DTMF tones when you pick up the call.

3. Press any key on your telephone; the control panel opens the audio

channel.

If you press “9” to answer the call, the control panel simultaneously cancels the siren

when opening the audio channel.

4. If the TWA mode is defined as “Simplex”, (see 10.6.12: 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.
