G4LF Series notification appliances provide the benefits of Gen
esis 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 pat
tern. 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 EDWARDS control equipment,
G4LF Series audible output remains synchronized with all Genesis
audible signals on the same Notification Appliance Circuit, includ
ing 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 configu
When connected to a compatible synchronization source, Genesis
appliances synchronize (strobes to UL 1971) to within 10 millisec
onds indefinitely without the need for external modules or other
equipment. See the Specifications section for a list of synchroniza
tion sources.
