Overview

What it is and who it is for

The Edwards 51XBRFR24D is a 51XBR Xtra-Brite combination audible and visual signal: a flashing LED beacon with a red lens and a built-in horn in one unit. It runs on 24V DC, draws 0.275 A, and is rated for indoor or outdoor use.

A polycarbonate double fresnel lens magnifies the LED, which has a median life (L70) of 148,000 hours based on the LED manufacturer's projections. The horn is rated 85 dB at 10 ft and is synchronized with the flashing LED. The cast base can be used as a junction box, and the unit mounts on 1/2 in NPT conduit, directly to a surface with the included hardware kit, or on a 4 in (102 mm) octagonal box. It operates from -31 to 150 °F (-35 to 66 °C); outdoor units must be mounted vertically with the lens facing up.

The 51XBR combination models come with amber, blue, green, red or white lenses at 24V DC or 120V AC. This model uses the 92-LR red lens, the 118-G1 horn and flasher P-041917-0028.

  • Best for: indoor or outdoor signaling points that need a flashing LED light and a horn from one 24V DC device.
  • System fit: 24V DC signal circuits; the unit draws 0.275 A continuous with a rated surge of 10 A for 120 microseconds.
  • Important to know: the datasheet lists cULus only, with no fire alarm strobe listing; outdoor units must be mounted vertically with the lens facing up.
