The Zhengtai Illuminated Buzzer (Model ND16-22FS) is a high-precision industrial-grade alarm device integrating audible and visual alerts into a compact 22mm package. Designed to operate across DC24V, AC220V, and AC380V environments, it delivers unambiguous warnings in critical control systems, production lines, and safety-critical applications. Dual-mode signaling ensures rapid notice recognition in noisy or visually challenging workspaces.
✅ Dual-Mode Alert System: Synchronizes piercing audio output (≥85dB) with vibrant Red LED illumination for instantaneous event signaling, acting as both an audible buzzer and visual indicator.
✅ Robust Multi-Voltage Support: Precisely engineered for universal compatibility with low-voltage (DC24V) and industrial AC power systems (AC220V-380V ±10%), eliminating separate inventory needs for diverse equipment.
✅ IP65 Protection: Sealed housing withstands dust ingress and low-pressure water jets, ensuring reliability in harsh environments like manufacturing plants or outdoor control cabinets.
✅ 22mm Mount Design: Simplified installation via standard panel cutouts with integrated locking ring (included) for secure vibration-resistant mounting. Terminal block accepts 22-18 AWG wire.
✅ High-Visibility Optics: Super-bright 620nm red LED achieves long-distance daylight perceptibility (≥80m visibility), complying with IEC 60073 safety color standards for critical notifications.
