Federal PA-20A Siren
Federal PA-20A Electronic Siren. Tested and working! All selector positions perform well. Selector switch is clean and smoothly moves between functions. The siren modes produce 24.5 VAC into a 10 ohm test load. The pilot lamp is functional also. The microphone jack is keyed for the Motorola 4 pin, Motrac, Mocom, etc. No mounting bracket or microphone is available. Used, tested and in very good condition. This PA-20A is very rare, and hard to find in such good condition!
