The B&M Siren Manufacturing Company was founded in Los Angeles in 1913
by James W Bayless and Lester H Miles.
The first sirens produced were friction driven motorcycle and automotive sirens.
In 1925, B&M began manufacturing automotive electro-mechanical sirens
and patented the first successful coaster siren clutch.
This innovation gave a better warning signal
and vastly increased the lifespan
of siren motors.
Over the last 100 years,
B&M has manufactured other types of sirens
as well, from small 6 inch diameter 1/2 horsepower General
Alarm sirens, up to 20 inch diameter 10 horsepower Air Raid sirens.
As we begin our second century of service, B&M is now focused on its most
accomplished endeavor; manufacturing the highest quality electro-mechanical
sirens available to the emergency responder. Our plan is to continue to give the best quality of manufacture, the best warranty,
and the highest level of service in the industry.
All B&M sirens are designed and made in the USA.
Components are sourced from companies in the US and Canada.
B&M does not utilize foreign sources that are controlled by repressive regimes.
