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 a 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 last generation Thunderbolt and current generation 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.
