The 508-128 is a uni-directional rotating siren produced by Federal Signal Corporation. The 508 name comes from the 500Hz frequency of sound it produces, deeper than its 2001-130 brethren, and the eight ports seen on the rotor and stator. This siren was born as a solution to compete with American Signal Corporation in the nuclear market due to an audible warning requirement of 500Hz, but is not limited to that market. It is quite popular among many cities looking for a new siren system.
Design
This siren is a mash of 3 sirens bundled into one. It utilizes the rotation mechanism and collector ring assembly from the 2001-130. It also utilizes the Eclipse-8 rotor and stator with a precisely designed projector made of fiberglass. All this ties together to make the 508-128.
