SCE028MD3DP2B

Alarms, Buzzers, And Sirens Overview

The SCE028MD3DP2B is an internally driven piezo buzzer from the SCE series by Mallory Sonalert. It operates on a voltage range of 16 to 28 VDC with a current draw of 40 mA. The device emits a fast double pulse tone at a frequency of 2.9 kHz, producing a sound pressure level of 75 dB at 16 V measured at 61 cm. Designed for panel mounting, it features terminal block connections and includes UL and cUL certifications.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezo technology for simplified circuit integration
• Fast double pulse output mode for distinct audio indication
• Compact panel-mount design with terminal block termination
• Certified for safety compliance with UL and cUL standards

Alarms, Buzzers, And Sirens Applications

• Industrial equipment status indicators
• Control panel alarm systems
• Medical device audio alerts
• General purpose audible signaling in enclosed enclosures

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct acoustic and electrical specifications. Confirm that the required voltage range aligns with your system's power supply. Check for updated certification marks such as UL or cUL if required for your region. Ensure panel cutout dimensions match the physical size specified in the mechanical drawings before finalizing procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, internally driven solution is needed for 16-28 VDC systems. The fast double pulse pattern distinguishes it from continuous tone alarms. Verify that the 75 dB SPL meets the ambient noise requirements of the installation environment. Consider the terminal block connection type for wiring compatibility with existing control panels.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SCE series of industrial-grade audio indicators. The series offers various voltage ratings and acoustic outputs tailored for different enclosure sizes and noise environments. The SCE028MD3DP2B specifically targets applications requiring moderate volume in a small form factor with certified safety ratings for North American markets.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct replacements must match the 16-28 VDC input, 2.9 kHz frequency, and fast double pulse operation. Verify physical dimensions for panel cutout compatibility and terminal block orientation. Ensure the replacement maintains equivalent sound pressure levels and safety certifications.
