Clifford & Snell YL4IS Series Red Sounder Beacon, 18 → 24 V dc, IP65, Fixed Mount, 100dB at 1 Metre

This bright red Clifford & Snell sounder beacon provides an effective auditory and visual alert in the event of a safety hazard. Its high-volume sound output of 100dB (decibels) within a 1m radius means it's easy to hear, even in loud workplaces. A choice of 32 tones lets you assign different sounds to different incidents for maximum versatility. You can easily switch between tones via a built-in DIL (dual in-line) switch. The bright red LED (light-emitting diode) provides a visual warning signal for additional safety. Use this sounder beacon to indicate a status change in large installations or to warn of a malfunction.

• Supply voltage of 18 to 24V DC makes it compatible with a range of devices

The sounder and the beacon are connected, so they work in tandem. When activated, the LED light starts flashing and the sounder emits the selected tone at the same time.
