Q2B

Later, electric motor driven sirens were widely manufactured by Federal Signal Corp, Sireno, Sterling and B&M beginning with six volt systems.

New York City's noise regulations made mechanical sirens obsolete there in the early 1970s as they were too loud and the sound was too widely projected.

The majority of users of the Q Siren are fire departments, although some ambulances and heavy rescue squads have employed the Q-siren.

Some fire departments and cities have banned the siren due to its loud volume, which led to them being substituted for electronic replica versions, such as the E-Q2B.

For many years FDNY has used the Federal Signal PA300 electronic siren, which then led to them being criticized for not sounding like a traditional fire truck.

Rescue 1 Members have been quoted as saying "the best thing about the new rig is that old fashioned siren that all other trucks have, it really gets your blood pumping hearing that.
