Federal Signal 450E-024 Audible Alarm

The Federal Signal 450E-024 is a gray panel-mount horn designed for 12 to 24V DC and 16 to 33V DC systems. It produces a continuous tone at 90 dB and draws 0.25 amps. The unit is built for indoor and outdoor use with a plastic housing that operates from -65 to 150 degrees F. It suits installers needing a compact, coded or sustained tone signal.

Plastic Housing with Surface Mount and Gasket

The horn measures 4.125 in height, 4.125 in width and 2.7969 in depth. Its plastic construction resists corrosion and meets Marine Rated, CSFM Compliant, cUL Listed, UL Fire Listed, UL Listed and ULC Fire Listed standards. A panel mount gasket is included to seal the surface mounting cutout against moisture and debris. No visual indicator is fitted, so the device provides audible warning only.

Verify Voltage, Cutout and Tone Requirements

Confirm the supply voltage falls within the 12 to 24V DC or 16 to 33V DC ranges before wiring. Ensure the panel cutout matches the 4.125 in square footprint for the supplied gasket. The continuous sound pattern and lack of visual output may not suit applications needing selectable tones or flashing alerts. Check that 90 dB output meets local audibility codes for the intended location.
