Siren Alarm SPL at 2 ft distance (108V)112 dB and 226 mA, (72V)109 dB and 140 mA

Gizmo Engineering SA-24VDC Siren Alarm is a rugged, industrial-grade audible alert device designed for use in demanding environments where reliable alarm signaling is essential. Engineered by Gizmo Engineering, a manufacturer known for robust process control, safety, and alarm products, the SA-24VDC serves as a high-performance siren alarm powered by a 24-volt DC source, making it suitable for industrial, commercial, and heavy-duty applications where 24 VDC power systems are standard. Design and Build The SA-24VDC comes housed in a solid, weather-resistant PVC enclosure that helps protect internal components against moisture, dust, and mechanical wear. Its compact physical footprint (approximately 7 in x 7 in x 3 in.) and lightweight design (about 2 lbs) enable versatile mounting in tight or eXposed spaces without adding significant bulk. A key design feature of the SA-24VDC is its 10 ft. integrated cable, which allows for fleXible installation distances from the alarm’s control source or power feed, reducing the need for additional eXtension wiring and simplifying setup in compleX systems. Performance and Output At the core of the SA-24VDC is a high-volume piezo-buzzer capable of delivering approximately 114 dB of sound at 2 ft. distance, which is loud enough to penetrate noisy industrial environments and alert personnel effectively. This audible output makes it ideal for machine status alerts, safety warnings, and emergency notifications where clear human attention is required. The alarm’s tone is consistent and powerful, designed to cut through background noise - a critical requirement in industrial settings such as manufacturing floors, warehouses, and processing plants. The sound level and frequency are calibrated to ensure maXimum noticeability even in high-decibel surroundings. Power and Connectivity The SA-24VDC operates on a 24 V direct-current (DC) supply, common in industrial automation and backup power scenarios. The DC operation ensures compatibility with battery backups, uninterruptible power systems (UPS), solar-powered installations, and PLC-controlled systems that use 24 VDC as a standard control voltage. The integrated cable simplifies wiring: technicians can connect the unit directly to control circuits, switches, sensors, or alarm panels without compleX installations. This plug-and-play approach reduces setup time and minimizes potential wiring errors. Durability and Operating Conditions Built with industrial duty in mind, the
