EDWARDS SIGNALING 120VAC Horn Strobe

This EDWARDS SIGNALING horn strobe is a facility safety device that delivers an audible and visual alert for building-wide notification systems. It operates on 120VAC power and produces an 85 dB output from a cast aluminum housing finished in red.

Who This Suits and Who Should Look Elsewhere

The unit suits installers wiring a 120VAC notification circuit who need a combined horn and strobe in a durable cast housing. It is not for buyers who require a different operating voltage or a lower sound-pressure level than the rated output.

Deciding Specification: 120VAC Operation

The single specification that determines fit is the 120VAC supply requirement; the device will only function on circuits providing that voltage. Verify the circuit voltage before purchase to ensure compatibility with the installed wiring.

Questions about this item

What size electrical box does the 51XBRFR120A horn strobe mount to?

The cast-aluminium housing is designed for standard 4-inch square or octagon boxes; verify the mounting-hole pattern before drilling.

How do I wire the 120 VAC supply to the 51XBRFR120A, and which step is often missed?

Connect line and neutral to the marked terminals, then secure the ground screw to the metal housing — omitting the ground connection is the most common error.

When should the strobe tube on the 51XBRFR120A be replaced?

Replace the strobe tube when flash intensity drops below the rated 85 dB output or after the manufacturer’s recommended service interval.
