ZA028MASU2

Alarms, Buzzers, And Sirens Overview

The ZA028MASU2 is an industrial piezoelectric buzzer from the Mallory Sonalert ZA series, designed for panel mounting. It operates on a voltage range of 16 to 28 VAC or VDC with a current rating of 40 mA. The device features a fast speed-up tone at a frequency of 3.3 kHz, producing a sound pressure level of 75 dB at 16 V measured at 61 cm. It utilizes terminal block connections and offers IP66/NEMA 4X protection ratings.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric transducer generating a fast speed-up audible alarm
• Robust construction providing IP66 ingress protection and NEMA 4X compliance
• Compatible with both AC and DC power supplies within the specified voltage range

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status and fault alarms
• Control panel warning indicators

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix code against official Mallory Sonalert documentation to confirm electrical characteristics and acoustic output. Ensure the terminal block interface matches the system wiring requirements. Confirm that the operating environment meets the specified temperature and ingress protection standards before integration.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a high-intensity, fast-responding audible alarm is required for industrial environments. The internal driver simplifies circuit design by eliminating external oscillators. Consider the 3.3 kHz frequency and 75 dB output for optimal audibility in noisy settings compared to lower decibel alternatives.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the ZA series of 22mm panel alarms, widely recognized for reliability in harsh conditions. The ZA series provides various acoustic patterns and voltage options, allowing engineers to standardize on a single form factor while adjusting performance parameters through different part numbers within the same product family.

Alarms, Buzzers, And Sirens Replacement Considerations

ZA028LASU2: Offers higher sound pressure (85-95 dB) and faster frequency (3.9 kHz). ZA028MASS1: Provides a slow pulse pattern with similar electrical specs. Verify mounting dimensions and terminal compatibility when substituting.
