ZA028SDSU2

Alarms, Buzzers, And Sirens Overview

The ZA028SDSU2 is an industrial piezoelectric buzzer from the Mallory Sonalert ZA series, designed for panel mounting in standard 22mm holes. It operates on 16-28V DC with a current draw of 40mA. The device features terminal block termination and internal drive circuitry. It produces a slow pulse tone at 3.3kHz with a sound pressure level of 65-75dB. The unit is rated IP66 and complies with RoHS standards.

Alarms, Buzzers, And Sirens Feature Summary

• Internal micro-controller drive circuitry for reliable operation
• Terminal block termination for secure electrical connection
• IP66 rating for protection against dust and water jets
• Compatible with standard 22mm panel cutouts

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Control panel alarm systems
• Equipment fault signaling
• Process monitoring alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix SU2 confirms the slow pulse tone and voltage range required for your application. Confirm that the terminal block termination matches your wiring infrastructure. Ensure the 22mm diameter fits the designated panel opening. Check for any specific environmental certifications needed for your installation zone.

Alarms, Buzzers, And Sirens Selection Notes

Select this model if a low-volume audible alert is sufficient for your system. The slow pulse pattern distinguishes it from continuous or fast-pulse alarms. Consider the 65-75dB output level relative to ambient noise. Verify that the 16-28V DC supply is stable within the operating range to ensure consistent performance.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the ZA series of 22mm panel alarms manufactured by Mallory Sonalert Products Inc. The series is characterized by its compact size, allowing integration into tight control panels. It utilizes piezoelectric technology for efficient sound generation without requiring external drivers.

Alarms, Buzzers, And Sirens Replacement Considerations

ZA028MASP1 offers similar panel mounting but features a different tone profile and potentially different acoustic output levels. ZA028LDMT6 provides multi-tone capabilities instead of a single slow pulse. Verify that any substitute maintains the same voltage range and termination type.
