Emergency Voice Speaker

The G4SWF provides clear reproduction of emergency voice messages and signaling tones.

Typical functions include:

• Evacuation instructions
• Emergency announcements
• Alert tones
• Prerecorded messages
• Live firefighter or operator paging

Because the G4SWF is a speaker-only appliance, it is intended for locations requiring audible voice notification without an integrated visual strobe.

25V / 70V Audio Operation

The G4SWF supports field-selectable:

25 VRMS

and

70 VRMS

audio operation.

This allows the same speaker to work with common emergency voice evacuation and fire alarm amplifier configurations.

Selectable Speaker Wattage

The G4SWF provides field-selectable speaker power taps:

¼ W

½ W

1 W

2 W

The appropriate setting can be selected according to required sound pressure, room acoustics, ambient noise, amplifier capacity, and emergency voice system design.

High Speech Intelligibility

The G4S speaker platform is engineered for clear 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.
