SC110DP

Alarms, Buzzers, And Sirens Overview

The SC110DP is an audio piezoelectric indicator manufactured by Mallory Sonalert Products Inc. It operates within a power supply voltage range of 30V to 120V and draws a maximum working current of 20mA. The device produces a fast pulse tone with a resonance frequency of 1.9kHz. At a distance of 609.6mm, it achieves a sound pressure level (SPL) of 75dBA. This component is designed for panel mounting applications requiring audible alerts.

Alarms, Buzzers, And Sirens Feature Summary

• Generates a fast pulse audio tone for clear alert signaling
• Operates on a wide DC voltage input range from 30V to 120V
• Features piezoelectric technology for reliable acoustic output
• Designed for direct panel mounting installation

Alarms, Buzzers, And Sirens Applications

• Industrial control panels requiring visual-audible status indication
• Equipment safety alarm systems operating at higher voltages
• Automated machinery fault detection alerts
• HVAC system operational status indicators

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'DP' against the 'DPR' variant to confirm RoHS compliance requirements, as the DP version is noted as not compliant in distributor records. Ensure the application circuit supports the 30-120V DC input range and that the 20mA current draw is compatible with the driving source. Confirm panel cutout dimensions match the physical housing specifications provided in the official datasheet before procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a fast pulse tone is required for high-voltage environments up to 120V. Compare with the SC110DPR if environmental compliance standards mandate RoHS certification, as the DP variant lacks this designation. Consider the 75dBA SPL at 609.6mm for noise floor compatibility in the target installation area. Verify that the piezoelectric driver interface matches the available control signals.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the Mallory Sonalert audio indicator family, specifically designed for industrial and commercial alarm applications. It serves as a standalone audible warning device that integrates directly into control circuits without external drivers. The product line emphasizes reliability and clear acoustic signaling across various voltage ranges, with the SC110 series focusing on mid-to-high voltage operation capabilities.

Alarms, Buzzers, And Sirens Replacement Considerations

The SC110DPR is a functionally similar alternative but differs in RoHS compliance status. Direct substitution requires verifying regulatory requirements for the end-use environment. No other exact pin-compatible replacements are documented in the provided data.
