The speech module (AZWG10100) is an expansion block of the GSM interface (AZWG10000). You can use it to transmit voice messages to up to 4 receivers. As soon as an alarm is triggered in your building, your alarm center knows the current status. The GSM interface sends this information in the form of an SMS or control center protocol (contact ID, SIA) via the mobile wireless network. The recipients are the up to eight telephone numbers that you have selected. If you expand the GSM interface with the speech module, you can alternatively record and send up to 4 voice texts, each lasting 10 seconds. In addition to controlling the inputs of the GSM interface, the voice messages can also be assigned to events such as sabotage, loss of the telephone line and/or the power supply or a low battery charge.
