Replacing our traditional Model 450, the NEW! Model 450E electronic horn offers a patent pending electronics design that produces a very loud, clear and distinctive electronic tone. This model is capable of producing sustained tones or coded blasts through push button or PLC control devices without duty cycle or interval limitations. The 450E is ideal for general alarm, start and dismissal, coded paging, and process control signaling in areas of high ambient noise levels. Additionally, the 4-wire terminal block and supervisory diode design also makes this unit ideal for Fire Alarm Applications.
Model 450E produces 99dBA @ 10' on axis and 90dBA @ 10' per the UL 464 reverberation test when supplied with a 24VDC input voltage. It produces 94dBA @ 10' on axis when supplied with a 12VDC input voltage. It has no detectable RF emissions in a 30 MHz to 1000 MHz frequency range which minimizes the potential for interference with nearby electrical devices.
The horn’s non-metallic, polycarbonate light grey (RAL 7035) housing and polymeric speaker cone material are corrosion resistant and weatherproof for improved durability in harsh industrial environments. Surface or flush mounting options allow for installation on walls, panels, 4-inch square outlet boxes, cabinets, or deep concrete wall constructions. A Double Projector accessory (Model PR2-NM) mounted on the front of the unit directs side sound output, optimizing signaling for long, narrow rooms or corridors.
The 450E is UL, cUL and ULC Listed and is approved for Marine and other Type 4X applications when installed with a Panel Mount Gasket (included) or the Non-metallic Weatherproof Backbox accessory (Model WB-NM).
