Overview

What it is and who it is for

The Edwards G4HFWF-S7 is a Genesis G4 Series High Fidelity 520 Hz wall speaker with a white housing and FIRE marking, built for 70 VRMS emergency audio circuits. Edwards states the speakers are part of an end to end audio system approved for use in sleeping areas when used with approved audio hardware and a factory supplied 520 Hz tone.

Wattage taps of 1/4, 1/2, 1 and 2 W are set by a switch visible through a window on the bottom. UL 1480 output at 10 ft for the 70 V HF model is 81.8, 84.6, 87.3 and 90.5 dBA at those taps, with a 400 to 4,000 Hz response from a 4 in sealed-back mylar cone. A DC blocking capacitor allows audio circuit supervision.

The speaker measures 6.5 x 5 x 1 in and mounts indoors on a wall, flush to a 4 in square box 2-1/8 in deep or a 100 mm European square box with no trim plate, or on a G4B (white) or G4RB (red) surface box. Terminals take 18 to 12 AWG wire.

  • Best for: sleeping areas that need a 520 Hz voice evacuation speaker on a 70 V circuit, with approved Edwards audio hardware.
  • System fit: 70 VRMS supervised emergency audio circuits on Edwards fire alarm and voice evacuation systems.
  • Important to know: this is a 70 V speaker only with no strobe, and speakers driven by third party audio systems are not UL approved for sleeping rooms; installation and programming must be done by a qualified fire alarm technician per local code.
