The Genesis LED EG4LF horn-strobe combines 520 Hz low frequency audible signaling with high-efficiency LED strobe output in a single wall-mount appliance. Built for commercial sleeping areas and other spaces where NFPA 72 requires low frequency notification, it handles both new installs and system upgrades - including mixed circuits with legacy Xenon strobes.
Built for the commercial installer
Field-selectable candela output (15, 30, 75, or 110 cd) draws the same current regardless of setting, which means NAC circuit calculations stay valid even when candela requirements change mid-project. The universal room-side wiring plate lets you pre-wire, continuity-check, and snap the device into place late in the build - no re-entering finished ceilings to troubleshoot wiring issues. Fits standard 1-gang, 2-gang, 4-inch square, and 4-inch octagon boxes.
Key features
- 520 Hz low frequency horn meets NFPA 72 sleeping area requirements out of the box
- Constant current draw across all candela settings - simplifies NAC circuit design and future adjustments
- LED strobe technology reduces power supply, battery, and wiring requirements vs. Xenon
- Backward compatible with existing Genesis and Xenon strobe circuits for easy retrofits
- Universal room-side wiring plate speeds rough-in and eliminates late-stage wiring errors
- Low-profile design protrudes approximately 1.5" from the mounting surface
System requirements
Operates on 16-33 VDC or 16-33 VFWR from any compatible FACP or NAC power supply. Synchronizes via CC1S/MCC1S signal modules, booster power supplies, or compatible intelligent and conventional fire alarm control panels. Maximum 20 ohms between any two synchronized devices on the same circuit.
