Overview
The SBT12VMPC is an internally driven audio indicator from the SBT series, manufactured by Mallory Sonalert Products Inc. It operates on a DC input voltage range of 9 to 12V. The device features a medium pulse sound profile with a frequency range of 150 to 4000 Hz. It provides a loudness level between 85 and 95 dB at a distance of 10 cm. The unit holds cUL recognition compliant with IEC60601-1-8 standards.
Feature Summary
- Internally driven driver circuitry for direct interface compatibility
- Compliance with IEC60601-1-8 safety standards for medical environments
- Medium priority ventilation melody sound profile
Applications
- Medical equipment alarm systems
- Ventilation status indicators
- Industrial audio alerts
Procurement Notes
Verify the specific suffix 'MPC' against official Mallory Sonalert documentation to confirm the exact sound profile and priority level. Ensure the operating voltage remains within the 9 to 12V DC range during integration. Confirm that the required acoustic output meets the 85 to 95 dB specification for the intended application environment.
Selection Notes
Select this component when a medically recognized audio indicator is required. The internal driver simplifies circuit design by removing external oscillators. The medium pulse characteristic distinguishes it from continuous tone alarms. Verify physical mounting requirements and terminal configurations against the mechanical outline drawing before finalizing the design.
Part Context
This part belongs to the SBT series of industrial-grade audio indicators. It shares the standard form factor and electrical interface characteristics common to the series. The specific MPC designation denotes a unique sound pattern optimized for medical ventilation applications, differentiating it from other variants in the product line.
Replacement Considerations
Consult the official Mallory Sonalert substitution guide for verified equivalents. Generic buzzers may not meet the IEC60601-1-8 recognition requirements or the specific acoustic parameters.
