4 Tone Audio Signal Indicator Units | e絡盟 Hong Kong

Element14 provides a curated selection of audio signal indicators that meet diverse industry needs - from compact buzzers to programmable voice annunciators. Our range supports applications requiring high audibility and reliable acoustic signalling.

Audio signal indicator units are designed to emit sound alerts in response to specific triggers within a process or system. These devices ensure that operators receive clear and immediate feedback in environments where visual alerts may not suffice.

Features include tone variation, volume control, continuous/intermittent sound options and wide operating voltages. Common use cases:

Assembly Lines: Alerting for production stops or faults.
Safety Systems: Emergency or evacuation alerts.
Public Infrastructure: Acoustic signalling in transport hubs or automated kiosks.
