Low Frequency Audible Signals Genesis G4LF Series
G4LF Series notification appliances provide the benefits of Genesis life safety signals with output suitable for applications requiring low frequency audible tones ✔️
✅ These high-performance appliances generate a crisp 520 Hz tone in the standard 3-3 temporal pattern , An optional setting configures the appliance for continuous audible output — a critical feature for notification appliance circuits that are coded with a CDR-3 coder module. G4LF appliances also feature field-configurable high and low dB output settings.
- When connected to compatible control equipment, G4LF Series audible output remains synchronized with all Genesis audible signals on the same Notification Appliance Circuit, including standard 3.2 kHz Genesis audible signals.
- Available G4LF models include audible-only appliances, as well as combination audible-visible signals. Combination appliances feature Genesis FullLight™ strobe technology, which produces a smooth light distribution pattern without the spikes and voids that characterize bulky specular reflectors. This ensures the entire coverage area receives consistent illumination exceeding UL-1971 light distribution requirements. It also results in a slim, low profile device that blends with any decor. Candela output is field configurable.
- When connected to a compatible synchronization source, Genesis appliances synchronize (strobes to UL 1971) to within 10 milliseconds indefinitely without the need for external modules or other equipment. See the Specifications section for a list of synchronization sources.

Application
Genesis G4LF Series appliances are UL 464-listed for low-frequency audible requirements. Models are also available in combination with a UL 1971-listed strobe light for indoor wall-mounted public-mode notification applications. Many codes and regulations now call for low-frequency audible appliances (520 Hz) in newly constructed sleeping rooms and also require strobe lights under some of these circumstances. Consult with your Authority Having Jurisdiction for details.
Combination audible-visible appliances are installed in accordance with guidelines established for visible (strobe) devices.
When used with a compatible synchronization source, all Genesis xenon-based strobes — audible units, and combination appliances — maintain fully synchronization indefinitely. This exceeds the UL synchronization requirements of 10 milliseconds over a two-hour period.
Installation
Genesis G4LF Series appliances mount to a standard 4 inch (102 mm) square electrical box using the provided mounting spacer or directly to a Genesis G4 surface mount box.
All Genesis appliances have two tabs at the top of the signal. Unlock the cover to reveal the mounting hardware. The shallow depth of Genesis devices leaves ample room behind the signal for extra wiring. Once installed with the cover in place, no mounting screws are visible.
