PUI Audio 95 dBA Panel Mount Continuous Buzzer 3 V dc Min 15V dc Max

PUI Audio Buzzer, 104db Sound Level, 3V to 15V Supply Voltage - LAI-3330-PR-WP

This buzzer is an electromechanical signalling device designed for panel installation in industrial settings. It produces a continuous tonal alert within a mid-to-high audible range and operates from low-voltage DC supplies, making it suitable for control panels and machine enclosures where a clear, persistent alarm tone is required.

Features and Benefits:

• Continuous tone at 2500 to 3500 Hz provides distinct audible alerts
  High sound output 104 dB ensures audibility in noisy environments
  Operates from 3 to 15 VDC allowing flexible system integration
  Low supply current 25 mA minimises power draw on control circuits
  Withstands -20 to 70 °C for reliable performance across environments
  Panel-mount format simplifies installation into control enclosures

Applications

• Suitable for industrial alarm and safety panels requiring loud alerts
  Ideal for machine status indication on factory control desks
  Used for access control systems needing a continuous audible signal
  Can be used for fault annunciation in building services equipment

What mounting method is required for installation?

It uses a panel-mount arrangement that secures directly into enclosure cut-outs for flush or semi-flush fitting.

How does the device affect power budgets in control systems?

It draws 25 mA during operation, enabling easy accommodation on low-current supply rails without additional power regulation.

What tone behaviour should be expected during fault signalling?

The output is a steady uninterrupted tone within the 2500 to 3500 Hz band suitable for sustained alarm conditions.

Which environmental conditions can it endure without performance loss?

It is specified to operate across temperatures from -20 °C up to 70 °C, supporting typical industrial ambient ranges.
