Meet the founder
More than five decades designing warning systems that protect people
Founder Neville McElroy has spent over 50 years designing, manufacturing and refining mechanical warning sirens for industrial, mining and emergency warning applications.
What began with transformers, welding equipment and industrial repairs evolved into a specialist focus on warning sirens, leading to the development of some of Sirenco's most recognised models used around the world today.
Neville's experience spans product design, manufacturing, field consultation and real-world deployment in some of the most demanding environments imaginable.
“A warning siren only has one job — to be heard when it matters most.

Our story
Built on practical engineering, not theory
Before Sirenco became known for warning sirens, the business manufactured transformers and welding equipment while operating a repair department servicing industrial machinery.
That hands-on exposure to demanding environments taught a simple lesson: equipment must be reliable, serviceable and built to perform under real-world conditions.
When Sirenco entered the siren market in 1970, that engineering mindset shaped every decision that followed. Today the same philosophy remains at the heart of the company.
