South Africa’s dedicated design and manufacturing facility. From 135dB emergency disaster sirens to custom microcontroller PCB assemblies — engineered, calibrated, and built to withstand the harshest environments.
135 dB Acoustic Power
Engineered for extreme mining, open-pit blasting, petrochemical plants, and disaster evacuation alerts.
Precision Microelectronics
Multilayer schematic routing, automated component placement, and Omron logic controllers.
Kenmare Facility
Full spectrum sound chamber testing, decibel meter calibration, and oscilloscope wave verification.
Energy Efficient
High-efficiency, rapid-dispatch acoustic warning sounders for indoor facilities, security, and gates.
Select an output power rating and warning tone pattern to calculate physical sound wave dispersion across outdoor and industrial factory yards.
Fabricated and bench-tested in our Kenmare workshop. Built with rugged cast aluminium housings, high-temperature copper windings, and Omron solid-state relays.
5 Year Warranty
Continuous-duty omni-directional motorized siren with reinforced cast shroud and integrated high-intensity strobe beacon.
5 Year Warranty
Heavy-duty weather-sealed cast aluminium body engineered for harsh outdoor environments, conveyor belts, and plant shift changes.
5 Year Warranty
UV-stabilised ABS body with BKV glass-filled nylon impeller. Powerful low-pitch penetration for railway lines and warehouse corridors.
Mil-Spec QA
Multilayer schematic routing, automated SMD component placement, Omron solid-state controllers, and custom logic firmware.
Low Current Draw
UV-stabilised ABS/PC blend offering adjustable multi-tone frequencies with ultra-low current draw (<50mA). Ideal for solar alarm setups.
Dual Signaling
Integrated acoustic sounder with a high-intensity red LED beacon in UV-stabilised ABS. Dual audio-visual notification for noisy plants.
Generate an instant technical configuration and estimated lead time for your custom electronics deployment.
Side-by-side engineering benchmarks across all official SBD Electronics security sirens and acoustic hardware.
