The Federal Signal SelecTone Model 300 is a lightweight and compact, solid‑state audible signaling device designed to amplify a pre‑selected tone over existing ambient noises. The speaker cone and projector are made of spun aluminum. The internal amplifier circuitry and tone module are contained in a housing of die‑cast aluminum. Dust‑ and moisture‑proof gasketing provides protection from the elements. All external components are sealed with gray enamel paint.
The Model 300 is designed for applications which have 12, 36, or 250VDC power supplies. The 250VDC version is UL and cUL Listed and CSA Certified. All models are rated Type 3R for indoor/outdoor use.
The Model UTM (Universal Tone Module) is used with this device to generate one of 32 tones. The Model 300 is designed to be used as a stand‑alone, full output unit and cannot be used with a SelecTone Command Unit (public address is not possible).
Internal ballast resistors are provided on 36VDC models. Maximum continuous output is up to 110dBa @ 10 feet (120dBa @ 1m).
Model 300 speaker/amplifiers are ideally suited for full output tone signaling where voice paging is not a requirement. Typical applications include emergency warning, start and dismissal, general alarm, smelters and cranes.
