The Edwards G4RF-S7 is a Genesis wall-mount fire alarm speaker. Specifically, it is the red-housing, FIRE-marked, 70 VRMS, standard-fidelity, speaker-only model in the Edwards Genesis G4 indoor signaling family.
First, the G4RF-S7 connects to a 70 VRMS constant-voltage audio circuit. Then its multi-tap transformer lets the installer select the appropriate power tap for the room. As a result, the device provides voice-evacuation or coded-tone audible notification at the chosen wattage.
Verified product attributes (per Edwards Genesis G4 catalog data)
- Type: speaker only (no strobe element)
- Voltage: 70 VRMS (constant-voltage audio bus)
- Fidelity: standard
- Housing color: red
- Lettering: FIRE
- Mounting: wall-mounted, indoor
- Replaced by: G4SRF (Edwards’ more recent equivalent in the same family)
What this is NOT
- Not a speaker-strobe — the “S7” designation is speaker-only (70 VRMS, no candela). For combined audible/visual with multi-candela strobe, see G4RF-S7VM (15/30/75/110 cd) or G4RF-S7V1575 (fixed 15/75 cd).
- Not a 25 V speaker — for 25 VRMS systems, see G4RF-S2.
- Not a high-fidelity speaker — for HF audio, see G4HFRF-S7 (the “HF” prefix indicates high fidelity for clearer voice intelligibility).
- Not a horn — for a 70 VRMS audible-only horn, that would be a different family; speakers operate on a constant-voltage audio bus, not a NAC.
About the multi-tap transformer
The G4RF-S7 uses a multi-tap transformer typical of 70 VRMS commercial audio appliances. Furthermore, the installer selects the wattage tap appropriate to the room size and required SPL. Specifically, the available taps (1/4 W, 1/2 W, 1 W, 2 W typical for Genesis G4) are chosen at install time; verify the actual tap ladder against the Edwards G4 speaker data sheet for the specific revision shipped.
Application
Typical indoor applications include voice-evacuation systems, mass notification, and coded-tone audible notification in offices, retail, healthcare, and similar indoor commercial spaces.
