Description
A Q2B Siren Motor is the part of a Federal Signal Q-Siren that creates the wailing sound associated with emergency vehicles. These sirens are known for their reliability and durability, and are often used on fire trucks .
The Q2B Siren Motor is a 12-volt, direct current (DC) motor. It is a heavy-duty motor that is designed to operate for long periods of time without failing. When the motor is turned on, it spins a shaft that is connected to a disc with holes in it. The disc is spun past a stationary plate, and the holes in the disc interrupt the flow of air between the disc and the plate. This interruption of airflow creates the wailing sound that we hear from sirens.
