Edwards G4LFWF-H. Horn Low Frequency.

Edwards G4LFWF-H 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. Furthermore, 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. G4LFWF-H 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. Additionally, 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.
