SCE120LA2DP2B

Alarms, Buzzers, And Sirens Overview

The SCE120LA2DP2B is a piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates within an AC voltage range of 48 to 120V and draws 40mA of current. The device emits a fast double pulse tone at a frequency of 2kHz with a sound pressure level of 85dB measured at 48V and 61cm. Designed for panel mounting, it features a 42.85mm diameter housing and utilizes terminal block connections. The unit is rated for operation between -40°C and 85°C and holds cUL and UL certifications.

Alarms, Buzzers, And Sirens Feature Summary

• Internal driver circuitry enables direct connection to AC power sources without external components.
• Fast double pulse mode provides distinct auditory alerts for critical status indications.
• Panel mount design with standard diameter facilitates integration into industrial enclosures.

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring audible fault alarms
• Electrical distribution equipment status monitoring
• Heavy machinery operator warning systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific voltage rating and pulse configuration against system requirements before procurement. Confirm that the terminal block interface matches existing wiring harnesses. Ensure the operating temperature range aligns with the intended environmental conditions. Check for updated certification marks if required by local regulations.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a loud, distinct alert is needed for high-voltage AC applications. The internal driver simplifies circuit design compared to passive buzzers. Consider the 42.85mm mounting hole requirement during panel layout. Evaluate the 85dB output level against ambient noise constraints in the installation area.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the SCE series of audio indicators from Mallory Sonalert. The series offers various voltage ratings and acoustic modes for industrial signaling. The SCE120 variant specifically targets higher voltage AC inputs, distinguishing it from lower voltage DC counterparts in the same product family.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other SCE series models with compatible voltage ranges and mounting dimensions. Verify that any replacement maintains the fast double pulse characteristic and terminal block termination style to ensure functional equivalence.
