SCE048XD3FP1B

Alarms, Buzzers, And Sirens Overview

The SCE048XD3FP1B is an internally driven piezoelectric buzzer from the SCE series by Mallory Sonalert. It operates on a DC voltage range of 28V to 48V with a current rating of 40mA. The device emits a constant tone at a frequency of 2.9kHz and achieves a sound pressure level of 95dB at 28V measured at 61cm. Designed for panel mounting, it features terminal block connections and functions within an operating temperature range of -40°C to 85°C.

• Constant tone operation mode
• Panel mount installation with terminal block termination

Alarms, Buzzers, And Sirens Applications

• Industrial equipment status indication
• Electronic alarm systems
• Control panel audio alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix FP1B against official Mallory Sonalert documentation to confirm the exact acoustic profile and terminal configuration. Ensure the input power supply strictly adheres to the 28V-48V DC specification to prevent component damage. Confirm that the application environment remains within the specified -40°C to 85°C operational temperature limits for reliable performance.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a constant audible alert is required for industrial panels. It is suitable for designs needing internal drive circuitry to simplify wiring. Verify that the 95dB output meets regulatory noise requirements for the intended installation location. Ensure the panel thickness accommodates the mounting hardware specifications provided in the mechanical drawings.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the SCE series of industrial audio indicators manufactured by Mallory Sonalert Products Inc. The series is characterized by robust construction for demanding environments. These devices are commonly used in automation and machinery where clear, high-decibel auditory feedback is necessary for operator awareness and safety compliance.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference part numbers such as SCE048XD3DB3B or SCE048XD2DP3B only if the specific frequency (2.9kHz) and constant tone mode are acceptable substitutes. Verify that alternative models match the 28-48V DC voltage range and 40mA current draw to ensure electrical compatibility without redesigning the power supply.
