AD16-22SM LED Flashing Sound and Light Buzzer for Secondary Distribution Panel Alarms

This AD16-22SM model flashing sound and light buzzer provides dual-mode alarm signalling through both audible intermittent sound and bright LED visual indications, designed specifically for secondary distribution panel applications and industrial control environments. The unit offers practical alert functionality across a comprehensive range of electrical systems with voltage options spanning from 12V to 220V in both AC and DC configurations. With 3C certification and standardised 22mm panel mounting, this buzzer delivers reliable alarm performance where clear signal notification is required for operational safety and system monitoring.

Features and Construction

The buzzer combines both audible and visual alarm elements in a single compact unit designed for panel mounting applications. Its construction prioritises clear signal delivery with the LED light source providing ≥ 100cd/m brightness for effective visual alerts alongside intermittent sound signals.

Material and Build

The buzzer features an LED light source as its primary visual component, producing brightness levels of ≥ 100cd/m to ensure clear visibility in various lighting conditions. The unit carries 3C certification and maintains insulation resistance of ≥ 2MΩ, supporting its use in electrical control applications where reliable performance and safety standards are required.

Size and Practical Fit

Designed for panel installation, the buzzer requires a 22mm mounting aperture, providing a secure fit in standard control panel configurations. This standardised sizing allows for straightforward integration into existing panel designs and electrical enclosures commonly found in secondary distribution systems.

Uses and Placement

With its combination of audible and visual signalling, this buzzer serves multiple alert functions in industrial and electrical control environments where clear notification of system status, faults, or operational conditions is necessary.

Event or Professional Use

In professional electrical installations and secondary distribution systems, the buzzer provides alarm signals for fault conditions, system status changes, or operational alerts. Its intermittent sound combined with LED flashing creates attention-grabbing signals that can be distinguished from background noise and visual clutter in industrial environments.

Everyday Industrial Use

For ongoing monitoring applications in control rooms, electrical panels, and equipment installations, the buzzer offers reliable alert functionality with minimal maintenance requirements. The availability in red, green, and yellow colour variations allows for different signal priority levels or system-specific coding according to operational requirements.

Benefits and Buying Value

The buzzer delivers practical value through its flexible voltage compatibility, dual-mode signalling, and standardised installation features that support reliable performance in various electrical control applications.

Reuse and Low Maintenance

With its solid-state LED light source and straightforward electrical design, the buzzer requires minimal maintenance while providing consistent alert performance. The wide voltage compatibility from 12V to 220V AC/DC supports installation across different system voltages without requiring additional components or voltage converters.

Why Choose This Product

This buzzer offers a practical combination of visual and audible alarm functions in a single unit with standardised 22mm panel mounting. The multiple voltage options provide installation flexibility, while the 3C certification and insulation resistance specifications support its use in regulated electrical applications where compliance and reliability are important considerations.
