ZA048MASR8

Alarms, Buzzers, And Sirens Overview

The ZA048MASR8 is a piezoelectric buzzer from the Mallory Sonalert ZA series, designed for panel mounting with terminal block connections. It operates on AC or DC input within a voltage range of 28 to 48V and draws 40mA of supply current. The device features internal drive circuitry and produces a slow pulse tone at a frequency of 3.3kHz. It delivers a sound pressure level of 65-75dB and meets NEMA 3R, 4X, and 12 ingress protection standards. Certified by UL and cUL, it functions reliably in temperatures ranging from -30°C to 65°C.

Alarms, Buzzers, And Sirens Feature Summary

• Internal drive circuitry enables direct connection to power sources without external drivers.
• Piezoelectric technology ensures consistent acoustic output across varying environmental conditions.
• Robust enclosure design provides high-level ingress protection suitable for harsh industrial environments.
• Dual certification by UL and cUL supports compliance with international safety regulations.

Alarms, Buzzers, And Sirens Applications

Alarms, Buzzers, And Sirens Procurement Notes

Verify that the specific suffix MASR8 corresponds to the required slow pulse tone and acoustic output specifications. Confirm compatibility with the operating voltage range of 28 to 48V AC/DC. Ensure the terminal block connection type matches the existing wiring infrastructure. Check for necessary certifications such as UL and cUL for the target region. Validate that the NEMA rating meets the environmental protection requirements of the installation site.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a reliable, internally driven audible indicator is needed for industrial panels. The 3.3kHz slow pulse tone offers distinct alert characteristics compared to continuous tones. The 40mA current draw is efficient for standard control circuits. Consider the 30.74mm diameter for panel cutout compatibility. The wide voltage tolerance simplifies integration into diverse power systems.
