Floyd Bell Audio Warning Device – 103 dB Piezo Alarm, IP68, PCB Mount

Compact, high‑impact warning for demanding environments

The Floyd Bell Audio Warning Device is a compact piezo alarm designed to deliver a clear, continuous alert when attention is needed. At roughly 1 inch in diameter and 0.875 inches tall, it remains unobtrusive on densely packed panels while producing an authoritative 103 dB at 2 feet—enough to cut through ambient noise in many work settings.

Designed for reliability, this unit supports a 5–15 VDC supply and draws about 50 mA, making it suitable for small control boxes, instrumentation enclosures, or rugged sensor housings where space is at a premium. The alarm can operate in continuous mode, providing an ongoing cue until acknowledged. In practice, this means you can deploy it on equipment that requires an unmistakable and persistent alert without occupying a large footprint.

Rugged by design: built to endure the elements

Environmental certifications back up practical performance. The device is ASTM B117 certified for salt spray exposure and IP68 certified for sealing against dust and water ingress. It tolerates salt spray for up to 300 hours and can withstand immersion and dusty environments without loss of function. This combination helps ensure dependable signaling in environments where moisture, salt, or particulate exposure are common.

• Salt spray endurance: up to 300 hours (ASTM B117)
• Complete seal against dust and submersion (IP68)
• Vibration tolerance from 0 to 55 Hz
• Water and dust resistance for harsh environments
