Quality

All B&M siren components are designed to provide maximum effectiveness, efficiency, and longevity.  We equip our sirens with only the finest bearings and other components.  Our stators, rotor tips and covers are all made of polished stainless steel. 

B&M siren clutches are the strongest and most free rolling in the industry.  Our clutches are made from heat treated tool and gear steels.  Our competitors use a 'drawn cup roller clutch', the housing of which is essentially stamped from a piece of sheet metal, with a plastic insert.

The manufacturing tolerances of B&M sirens are significant to their performance and efficiency.  A big, loose siren is like a worn-out pump; a lot of wasted energy for similar output.

One of our competitors does not even sell parts for their siren motors.  They apparently expect their customers to pay for a whole new motor when the brushes or bearings need replacement.  We maintain an inventory of every individual part that goes into our sirens, and almost never sell a complete replacement motor.  It just isn't usually necessary.  Our motors are made by us, here in the USA.

The typical well used, but well cared-for 40 year-old B&M siren that comes in for service needs only motor brushes, bearings, a good cleaning, and a few specialized factory procedures to return it to full factory performance.  Unless it has been severely damaged, we can restore virtually any B&M siren, of any vintage, to its original factory performance.  Please see the 'B&M Service' page.
