PSTN communication module complete with 4 mounting supports.

EN 50131, grade 2 certified.

Thanks to its extremely compact dimensions (60 x 75mm) it can be housed directly inside the metal container of the control panel.

Thanks to the PSTN module, the communicator functions of the burglar alarm control unit can be activated: it will therefore be possible to send alarms, report faults or any other status of the control unit by sending voice messages recorded in the control unit.

By combining it with the GSM 4231 or 4232 communicator it can work as a preferential communication channel, as a GSM back-up or in parallel managing two simultaneous calls (one on PSTN and the other on GSM).

Furthermore, it is possible to manage your system by calling the control unit: a guided voice menu will allow you to activate scenarios, exclude or include zones, activate or deactivate outputs.

Finally, it allows you to connect the burglar alarm system with the surveillance centres: alarm signals can be sent via the Contact ID or SIA protocol.

All with various programmable options: telephone line presence control and protection against wire cutting, enabling of the answering function with relative number of rings, skip answering to allow the connection of any other devices, such as fax (answer to the second call).
