## Summary description

SATEL SM-2 is an expansion module for alarm control panels that provides PSTN communication and a speech synthesizer for alarm notifications. Designed to integrate with compatible SATEL control units, it enables voice alarm alerts over fixed telephone lines, improving remote notification and response. Suitable for commercial and residential security installations requiring landline alarm reporting.

## Long description

SATEL SM-2 is an expansion module for compatible SATEL alarm control panels that adds PSTN communication and a speech synthesizer for audible alarm notifications over fixed telephone lines. The module is intended to complement existing SATEL control units, enabling automatic voice calls to predefined numbers and improving the clarity and reliability of alarm reporting where a landline is available. It is designed for integration into commercial and residential security systems that require spoken alarm alerts in addition to conventional signalling methods.
Advantages
The SATEL SM-2 provides voice notifications via PSTN, allowing recipients to receive spoken information about alarm events, which can improve response decisions. Integration with SATEL control panels ensures compatibility with alarm logic and event reporting already present in the system. Use of the fixed telephone network offers an alternative communication path where mobile or IP channels may be restricted or unavailable. The module's speech synthesizer delivers clear, pre-recorded or synthesized messages to convey event type and basic location details.
Suitable for
 Commercial premises requiring landline-based alarm notification
 Residential properties where voice alerts improve occupant awareness
 Installations that need an alternative or backup communicaton channel alongside GSM/IP
 Systems using compatible SATEL control units that support expansion modules
Key specifications
 PSTN communicator for fixed telephone line connection
 Built-in speech synthesizer for voice alarm messages
 Integration capability with SATEL alarm control panels
 Automatic calling to predefined telephone numbers
 Configurable message content and call sequence via control panel programming
How to use
Install the SATEL SM-2 expansion module into a compatible SATEL control panel following the manufacturer's installation guidelines and wiring diagrams. Connect the module to the fixed telephone line (PSTN) and configure the control panel to enable PSTN reporting and define the list of telephone numbers to be called in the event of alarm conditions. Set up and test the synthesized messages and call sequences through the control panel programming interface to ensure correct event-to-message mapping and volume levels for the speech output.
Usage recommendations
Verify compatibility with your SATEL control panel model before installation and perform on-site testing after configuration. Maintain a reliable PSTN connection and periodically test voice notifications to confirm clarity and correct recipient numbers. Consider keeping complementary reporting paths (GSM/IP) active to ensure redundancy in alarm communications.
