Edwards Genesis Horn/Strobe Replacement Guide: Wall, Ceiling & Outdoor Models

Replacing Edwards Genesis notification appliances? Whether you need a wall-mount horn/strobe, ceiling speaker/strobe, or outdoor-rated WG4 device, this guide covers the complete Genesis product line — model numbers, candela ratings, and key selection criteria — to help you find the exact replacement part.

Genesis Wall-Mount Notification Appliances

The Genesis wall-mount series is the most widely installed Edwards notification appliance line. Key features include multi-candela strobe output (selectable via switch), low current draw, and universal mounting on standard electrical boxes.

Genesis G4 Series (Full-Size Wall Mount)

The G4 is the standard Genesis wall appliance, available in these configurations:

  • Horn only — G4AWF (white/FIRE), G4ARF (red/FIRE). Temporal or steady tone output.
  • Strobe only — Multi-cd selectable output (15/30/75/110 cd). UL 1971 listed.
  • Horn/Strobe — Combined audible and visual notification in a single device. Most popular for general use.
  • Chime/Strobe — For alert/notification applications where a softer tone is appropriate.

Color options: Red with FIRE marking, Red without marking, White with FIRE marking, White with ALERT marking, White without marking.

Genesis EG1 Compact Series

The EG1 compact series offers the same Genesis performance in a slim profile ideal for corridors and areas with limited wall space. Available as horns, strobes, and horn/strobes in red and white.

Genesis Low-Frequency (520 Hz) Appliances

NFPA 72 requires 520 Hz low-frequency sounders in sleeping areas (hotel rooms, dormitories, patient rooms). Edwards Genesis low-frequency models include:

  • G4LFRF-H — Low-frequency horn only, red, FIRE marking
  • G4LFRF-HVM — Low-frequency horn/strobe, red, FIRE marking
  • G4LFRN-HVM — Low-frequency horn/strobe, red, no marking

Important: Standard 3 kHz horns are NOT compliant for sleeping areas. If you’re replacing horns in hotel rooms or dorms, verify you’re using 520 Hz models.

Genesis Ceiling-Mount Notification Appliances

Genesis ceiling appliances use the GC- prefix and are designed for overhead mounting. They require a GP10 room-side wiring plate (ordered separately) for installation.

  • Ceiling Horns — GCARF (red/FIRE), GCAWF (white/FIRE)
  • Ceiling Strobes — GCVRF (red/FIRE, 15-115 cd), GCVWF (white/FIRE)

  • Ceiling Speaker/Strobes — GCSVRF (15-115 cd), GCSVHRF (135-185 cd, high output)

Genesis Speakers & Speaker/Strobes

Genesis speakers provide voice evacuation capability when connected to an Edwards audio system (EAEC, 1B3-125, or 1B3-250 amplifiers). Available in 25V and 70V configurations:

  • Wall Speakers — G4RF-S7 (70V, red/FIRE), G4WF-S7 (70V, white/FIRE), G4R-S2 (25V)
  • High-Fidelity Speakers — G4HFRF-S2 (25V, red), G4HFWF-S7 (70V, white). Enhanced audio quality for large spaces.

The WG4 outdoor series is weatherproof-rated for exterior fire alarm applications. Designed for parking garages, loading docks, building exteriors, and covered walkways.

  • Outdoor Horns — WG4WF-H (white/FIRE), WG4RF-H (red/FIRE)
  • Outdoor Horn/Strobes — WG4WF-HVMC (standard cd), WG4WF-HVMHC (high cd)
