KD-EG4LFWF

The Kidde Genesis LED EG4LFWF is a 520 Hz low frequency wall horn built for sleeping area notification per NFPA 72. It drops onto standard electrical boxes with no adapter plates on most common configurations, draws significantly less current than mechanical horns, and lets you load more devices per NAC circuit without hitting power limits.

Built for the fire alarm installer

UL 464 and ULC-S525 listed with CSFM and MEA approvals. The Genesis LED platform delivers consistent 520 Hz output at selectable high (83 dBA) or low (78 dBA) sound levels with temporal or steady signal patterns. Operating voltage range of 16-33 VDC or 16-33 VFWR gives you flexibility across panel types without worrying about voltage drop on long wire runs.

Key advantages

  • Low current draw: as low as 43 mA DC in low-output mode - load more horns per NAC circuit before hitting panel limits
  • 520 Hz low frequency output: meets NFPA 72 requirements for sleeping area and pillow-level notification
  • Selectable output: field-switchable between high/low dB and temporal/steady signal patterns without swapping hardware
  • Universal box compatibility: mounts to 1-gang, 2-gang, 4-inch square, and 4-inch octagon boxes (GOCT adapter for octagon)
  • White housing with FIRE marking: pre-printed marking saves labeling time on job closeout
  • Wide voltage tolerance: 16-33 VDC or VFWR covers standard NAC circuit voltages with room for voltage drop

Mounting and wiring

Ships with GRSW wiring plate included. Accepts 12-18 AWG field wiring. Optional G4TW white trim plate available for a finished look on 4-inch square box installations.

Does the EG4LFWF meet NFPA 72 requirements for sleeping areas?
Yes. The 520 Hz low frequency output meets NFPA 72 requirements for sleeping area and pillow-level notification, including areas where audible notification must meet the low frequency criteria.
What electrical boxes does this horn mount to?
The EG4LFWF mounts directly to 1-gang, 2-gang, and 4-inch square boxes. For 4-inch octagon boxes, use the GOCT adapter plate. The GRSW wiring plate is included in the box.
How many Genesis LED horns can I load on one NAC circuit?
As low as 43 mA DC (low) and up to 123 mA DC (high). Compare against your panel's NAC capacity and total circuit load. The low draw lets you stack far more devices than mechanical horns per circuit.
Can I switch between high and low dB output in the field?
Yes. Both volume (high/low dB) and signal pattern (temporal/steady) are field-selectable on the device. No hardware swap needed.
What voltage range does the EG4LFWF support?
16-33 VDC or 16-33 VFWR. This covers standard NAC circuit voltages from most fire alarm control panels, with enough headroom for voltage drop on longer wire runs.
Is the FIRE marking pre-printed or do I need to add a label?
The FIRE marking is factory-printed on the white housing. No additional labeling required for code compliance on most standard installations.
What trim plate works with this horn?
The G4TW white trim plate (sold separately) provides a finished appearance when mounted on 4-inch square boxes. The trim plate covers the box gap for a clean, flush look.
Does this horn work with FWR (full-wave rectified) NAC circuits?
Yes. Operates on both filtered DC (16-33 VDC) and full-wave rectified (16-33 VFWR) NAC circuits. Current draw differs between DC and FWR - check the spec sheet for exact values per setting.
