Operation of 2-Way Audio
Two types of audio communication are possible;
Listen-in
In this mode, the panel will stay on-line for 30 seconds after sending an alarm signal to the ARC to allow the
operator to listen to the audio on site. The operation is controlled by the remote DTMF telephone and is as
follows:
1. Press the * then 6 keys to start listen-in.
2. Use the 0 and 1 keys to toggle between listen and talk modes (0 = listen, 1 = talk).
3. To end the call, press the * then # keys.
4. The call ends with three beeps.
Dial-in
In this mode, a user can dial into the alarm system from a DTMF telephone and type in a special PIN code
(controlled in Menu 42, User 99). This will allow the user to listen to the audio on site, and talk to the site. The
operation is controlled by the remote telephone and is as follows:
1. Dial in to either the PSTN number or the GSM audio number.
2. The panel answers after the number of rings set up in Menu 56.1.09.
3. Wait for a long tone then enter the PIN code to start listening.
4. Use the 0 and 1 keys to toggle between listen and talk modes (0 = listen, 1 = talk).
5. To end the call, press the * then # keys.
6. The call ends with three beeps.
In both modes, if no commands are detected within two minutes the call will be timed out and hung up. If the
remote user hangs up without using * and # then it can take up to two minutes before the call times out at the
panel end.
