The Edwards G4SVWF FIRE Wall Speaker Strobe White is an audible/visible fire alarm notification appliance designed for emergency voice and evacuation systems. It combines a high-fidelity speaker with an energy-efficient LED strobe in a white wall-mount housing with FIRE marking.
The G4SVWF supports both 25V and 70V audio systems, multiple selectable speaker wattage settings, and field-selectable strobe intensity. It is part of Edwards’ G4S Series of wall-mounted speakers and speaker-strobes.

Emergency Voice Speaker
The G4SVWF is designed for clear reproduction of emergency voice messages and signaling tones.
Typical functions include:
- Evacuation instructions
- Emergency announcements
- Alert tones
- Prerecorded messages
- Live emergency paging
The speaker provides high speech intelligibility for emergency voice/alarm communication applications.
25V / 70V Audio Operation
The G4SVWF supports field-selectable:
25 VRMS
and
70 VRMS
speaker operation.
This allows the appliance to work with common fire alarm voice evacuation and emergency communication amplifier configurations.
Selectable Speaker Wattage
The speaker provides field-selectable power taps:
¼ W
½ W
1 W
2 W
The appropriate wattage can be selected according to required sound level, room acoustics, ambient noise, amplifier capacity, and emergency voice coverage.
Selectable LED Strobe
The G4SVWF incorporates an energy-efficient LED strobe with selectable visual output.
Available candela settings are:
15 cd
30 cd
75 cd
110 cd
This allows a single appliance to accommodate multiple visual notification coverage requirements.
LED Strobe Technology
The G4SVWF uses LED technology rather than a traditional xenon flash tube.
The Genesis LED platform is designed to provide efficient visual signaling with reduced current consumption, helping reduce notification circuit loading and overall system power requirements.
FIRE Configuration
The specific G4SVWF configuration is:
Model: G4SVWF
Device Type: Speaker Strobe
Color: White
Marking: FIRE
Lens: Clear
Mounting: Wall
Speaker Voltage: 25 / 70V
Speaker Taps: ¼ / ½ / 1 / 2 W

High Speech Intelligibility
The G4S speaker platform is engineered for intelligible emergency voice reproduction.
Edwards publishes a Speech Transmission Index of approximately:
STI 0.81
This provides strong speech intelligibility for evacuation instructions and other emergency voice communications.
Synchronized Notification
The G4SVWF supports synchronized visual notification with compatible Edwards equipment.
Synchronization coordinates multiple strobes within the same field of view so they flash together rather than independently.
