Federal Signal PA300 Siren 690000 100W – New in Box Surplus

PA300 Siren Amplifier

The Federal Signal PA300, model 690000, is a 100-watt siren and public address amplifier that mounts in a vehicle and drives a separate siren speaker. One compact control head gives the operator electronic siren tones, a horn function, a radio rebroadcast setting and a handheld microphone for voice announcements. This unit comes from US Army stock, so it suits fleet builders, emergency vehicle restorers and collectors of issued equipment.

Features

• 100-Watt Output — The amplifier is rated at 100 watts and is meant to run a matching siren speaker, which is sold separately and not shown.
• Wail, Yelp And Hi-Lo Tones — The rotary selector covers Wail (a slow rise and fall), Yelp (a fast, urgent warble) and Hi-Lo (an alternating two-note tone).
• Manual Mode — A dedicated Manual position puts the siren tone under the operator's direct control instead of a fixed cycle.
• Radio Rebroadcast — The Radio position routes two-way radio audio out through the vehicle speaker so crew outside the vehicle can hear traffic.
• Horn/Siren Toggle — A front-panel toggle switch selects between the horn and siren functions.
• Gain Control With Off — A separate gain knob sets PA volume and doubles as the off position.
• Handheld PA Microphone — The Federal Signal branded microphone has a coiled cord and a rear mounting tab so it can hang on a dash clip between uses.
• Vented Control Head — Perforated top and side panels on the black enclosure let heat escape during long siren runs.

Government Surplus Issue

This PA300 was procured by the US Army, not built for the retail aftermarket, and it carries the Federal Signal Corporation and PA300 Series markings on the faceplate. Federal Signal is a long-standing maker of emergency warning equipment, and the PA300 control layout matches the hardware fitted to service vehicles. For anyone outfitting a utility, security or restored emergency vehicle, an issued unit gives you the original specification and provenance.
