Many factories rely on tower lights to visualize machine status, but the audible buzzer alert is often an afterthought. Picking the wrong buzzer mode is a common, costly mistake: operators may ignore critical faults, or get desensitized to alarms from constant unnecessary noise.

There are two standard buzzer modes widely used on industrial signal tower lights: steady continuous sound and intermittent alarm beep.

Steady Sound Buzzer

A steady buzzer emits a continuous, non‑stop tone once activated. This mode is reserved for high‑priority events: critical equipment failure, emergency stop, and urgent breakdown alerts. Keep this limitation in mind: prolonged continuous sound can lead to operator fatigue over long shifts.

Intermittent Alarm Buzzer

An intermittent buzzer cycles between short beeps and silent gaps. It works best for routine warnings, pre‑alarm notifications, and machine standby reminders. The pulsing tone is less intrusive, making it easy for your team to separate minor warnings from serious failures.

When Do You Need a High‑Decibel Buzzer?

Standard buzzers work well in quiet workshops. But loud production environments demand extra volume. Upgrade to a high‑decibel buzzer if:

• Your workshop has heavy background mechanical noise
• Operators work far away from the monitored machine
• You need clear, noticeable alerts across a large production line

ONN Tower Light Buzzer Options

Our ONN signal tower light series supports optional buzzer modules, configurable for either steady tone or intermittent alarm. We also offer high‑decibel buzzer versions built specifically for noisy factory environments, to ensure alerts cut through background noise reliably.
