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.

FAQs

Does this horn-strobe meet NFPA 72 sleeping area requirements?
Yes. The 520 Hz low frequency audible output meets NFPA 72 requirements for notification appliances in commercial sleeping areas such as hotels, dormitories, and assisted living facilities.
Does current draw change when I switch candela settings?
No. The Genesis LED EG4LF draws the same current at 15, 30, 75, and 110 cd. NAC circuit calculations remain valid regardless of which candela setting is selected, and you can adjust settings in the field without recalculating the circuit.
Can I mix this LED device with existing Xenon strobes?
Yes. Genesis LED devices can be installed on the same circuit as legacy Xenon strobes. This makes the EG4LF a practical choice for phased upgrades where you're replacing devices over time rather than all at once.
What electrical boxes does this fit?
Standard 1-gang, 2-gang, 4-inch square, and 4-inch octagon boxes. For 4-inch octagon boxes, use the GOCT adapter plate. Surface mount options available via the G4RSB (red) or G4WSB (white) back box.
What synchronization sources are compatible?
CC1S and MCC1S Series signal modules, booster and auxiliary power supplies, and compatible intelligent and conventional fire alarm control panels. Maximum loop resistance is 20 ohms between any two synchronized devices.
How do I change the candela or sound output setting?
Candela output (15/30/75/110 cd) and horn level (high/low) are set via slide switches accessible under the device cover. No special tools required. Settings can be adjusted after installation without removing the device from the wall.
