Gizmo Engineering SA-12VDC Siren Alarm is a compact, high-intensity audible and visual alert unit powered by 12 V DC. It’s engineered to provide immediate, unmistakable notification in industrial environments, manufacturing floors, tank farms, remote installations, and any location where alarm conditions must be broadcast clearly and reliably. Built with durability in mind, this siren alarm combines a powerful piezo buzzer with a strobing LED light housed in a weather-resistant enclosure, making it suitable for both indoor and outdoor use. Its relatively simple installation and straightforward 12 V DC operation make it easy to integrate with eXisting control systems, sensor outputs, or PLC logic circuits. High-Volume Audible Alert The SA-12VDC produces an eXtremely loud alert at approximately 114 dB at 2 ft, ensuring that alarm conditions are perceived clearly even in noisy industrial settings. The piezo-type buzzer is engineered for long life and immediate activation, providing a sharp, attention-demanding tone that cuts through ambient noise. Bright Visual Indicator Alongside the audible signal, the alarm includes a strobing LED beacon that provides a highly visible visual cue. This is especially useful in bright or noisy environments where sound alone might not be sufficient. Robust Construction The alarm is housed in a PVC enclosure that resists common industrial contaminants such as dust, moisture, and light liquids. Switches and eXternal hardware, such as screws, are typically stainless steel to resist corrosion. Simple Power & Wiring Designed for 12 V DC operation, the SA-12VDC uses a 10-ft cable (included) for fleXible installation and wiring to a power source or control system. The DC power requirement allows the siren to be easily integrated into battery-backed systems, solar installations, vehicle-mounted control panels, or standard industrial power buses.
