Description
Product Description The AD16-22SM 22mm LED Active Flash Signal Buzzer is a dual-sensory industrial warning device that combines an audio alarm with a visual alert in a single, compact chassis. When triggered, it emits a piercing, intermittent beeping sound accompanied by a highly visible, synchronized flashing red LED matrix. Constructed from impact-resistant, flame-retardant materials, this panel-mount component is engineered for heavy-duty fault monitoring, safety signaling, and automation status tracking. It features an advanced internal driver circuit that ensures long-lasting performance and low power consumption, making it an ideal choice for complex distribution boards and automated machineries where clear operator alerts are mandatory. ### Key Features Dual Alert System: Provides an intermittent audio buzz (≥80dB at 1 meter) alongside a flashing red light for guaranteed noticeability. Standard 22mm Footprint: Slim, cylindrical body fits perfectly into standard industrial knockout holes without crowding panels. Energy Efficient: Utilizes a low-current LED chip and an efficient buzzer mechanism, drawing less than 20mA of power. Secure Terminal Blocks: Equipped with rear screw-clamp terminal connections for fast, reliable, and vibration-resistant wiring. ## Compatibility Guide This flash buzzer is a universally structured industrial component. Its integration relies strictly on physical panel dimension matching and choosing the correct operating voltage for your circuit chassis. ### 1. Structural & Installation Compatibility Panel Cut-out: Drops directly into standard 22mm (7/8 inch) circular mounting holes, making it a drop-in match alongside standard push-buttons, emergency stop switches, and traditional pilot lamps. Enclosure Compatibility: Ideal for control boxes, custom automation panels, generator control systems, distribution boards (PDBs), safety test benches, and marine or automotive custom dash enclosures. ### 2. Electrical Systems Compatibility ⚠️ Important Voltage Note: The AD16-22SM series chassis looks identical across all variations, but internal coils are voltage-specific. Ensure your unit matches your exact system voltage: Low-Voltage DC/AC Systems: The 12V or 24V variants are compatible with automotive relays, PLC output modules (24V logic), solar battery storage banks, and low-voltage control circuits. Mains AC Systems: The 110V or 220V–240V variants wire directly in parallel across standard mains utility lines, grid distribution blocks, or heavy industrial machinery contactors. ### 3. Comparable Models & Universal Substitutes Because these are commodity components built to global electrical panel standards, this unit can be directly replaced by or mixed with alternative brands matching the 22mm alert lamp profile: TOMZN AD16-22SM Series Flashing Buzzers Onpow 22mm Flash Buzzer Indicator Series Haboo AD16 Intermittent Sound & Light Signal Lamps CentIoT / amiciSense 22mm LED Active Alarm Indicators
