Signal horns, also known as audible alarms, sounders, or electronic sirens, are industrial signaling devices designed to emit a distinct acoustic warning or notification in automated systems. These devices are characterized by their sound pressure level (measured in dB), frequency range (often adjustable for different tones), and operating voltage (typically 12V DC, 24V DC, 110V AC, or 230V AC). They are available in continuous or pulsed tone variants, with some models featuring multiple selectable tones for specific alarm conditions. The enclosures are usually rated IP65 or higher for harsh environments, and materials include polycarbonate or ABS for durability. Internally, they may incorporate piezoelectric or electromagnetic transducers, with options for integrated flashing LED beacons for combined visual-audible signaling.
Signal horns are deployed across a wide range of industrial sectors, including manufacturing plants, oil and gas facilities, chemical processing units, power generation stations, and building automation systems. They are commonly installed in control panels, machinery cabinets, conveyor systems, and emergency alarm networks. In process automation, they serve as critical components for fault indication, start-up warnings, or evacuation alerts. They are also used in transportation hubs (airports, train stations) and public address systems for general notifications. Their robust design ensures reliable operation in dusty, wet, or explosive atmospheres when certified accordingly.
Within our catalog, signal horns are categorized by type: electronic sounders, piezoelectric horns, and electromagnetic sirens. Key subcategories include multi-tone sounders (e.g., models with up to 32 selectable tones), weatherproof sounders (IP66), and explosion-proof sounders (ATEX/IECEx certified). Article codes typically follow a pattern like "SH-XXXX-YY", where "SH" denotes signal horn, "XXXX" indicates sound pressure level (e.g., 0100 for 100 dB), and "YY" specifies voltage (e.g., 24 for 24V DC). Examples include SH-0100-24 (100 dB, 24V DC) and SH-0120-230 (120 dB, 230V AC). We also stock accessories like mounting brackets and volume control modules.
