25. REMOTE LISTENING AND 2-WAY VOICE COMMUNICATION
ESIM384 can be equipped with a microphone (NOT INCLUDED!), that allows the user to listen on his mobile phone to what is happening in
the secured area. By installing the audio module EA2, the user will be able to have a 2-way voice communication (see 32.3.2. EA2 – Audio
Output Module with Amplier). Remote listening and 2-way voice communication can operate under the following conditions:
• The system makes a phone call via GSM to a listed user phone number in case of alarm and the user answers the call.
• The user initiates remote listening by sending the SMS text message, the system makes a phone call via GSM to the user phone number
that the SMS text message was sent from and the user answers the call.
