Description

The Edwards WGSVWF FIRE Outdoor LED Speaker Strobe is an outdoor-rated audible/visible notification appliance designed for fire alarm and emergency voice applications in wet or harsh environments. Edwards identifies the WGSVWF specifically as the white FIRE-marked speaker-strobe in the WG Series.

The appliance combines a high-intelligibility loudspeaker with a field-selectable LED strobe. It is suitable for either wall or ceiling mounting and supports both 25.2V and 70.7V speaker circuits.

Outdoor LED Speaker Strobe

The WGSVWF belongs to Edwards’ outdoor WG Series, which is designed for wet and harsh environments. Edwards lists an operating temperature range extending from approximately -40°F to 151°F (-40°C to 66°C) for the family.

This makes the appliance suitable for locations where standard indoor speaker strobes would not provide appropriate environmental protection.

Selectable LED Strobe

The visual portion provides two field-selectable settings:

15 cd

30 cd.

Edwards states that WG Series strobes are precision-timed to meet UL 1971 synchronization requirements when used with compatible system equipment.

Speaker Operation

The speaker supports dual-voltage operation:

25.2 V

70.7 V.

The appliance uses an efficient mylar-cone loudspeaker designed for intelligible emergency voice reproduction.

It can reproduce:

• Evacuation messages
• Emergency instructions
• Alert tones
• Live paging
• Other emergency voice communications

Selectable Speaker Output

WG Series speakers provide field-selectable output taps with published sound output ranging from approximately:

78 dBA to 87 dBA.

The selected speaker tap should match the required sound level, amplifier capacity, and emergency voice system design.

FIRE Configuration

The specific WGSVWF configuration is:

WG: Outdoor-rated series
SV: Speaker/Strobe
W: White housing
F: FIRE marking.

Edwards’ ordering information separately identifies:

WGSVWF — White housing, FIRE marking

and

WGSVRF — Red housing, FIRE marking.

Synchronized Visible Notification

The WGSVWF supports synchronized LED strobe operation.

Synchronization causes compatible strobes within the same field of view to flash together rather than independently, supporting coordinated visible notification. Edwards states that WG Series strobes are designed to meet UL 1971 synchronization timing requirements.

Electrical & Audio Information

Speaker Voltage: 25.2 / 70.7 V

Strobe Output: 15 / 30 cd

Strobe Technology: LED

Notification Type: Audible / Visible

Mounting: Wall or ceiling

Housing: White

Marking: FIRE

Environment: Outdoor / wet / harsh locations.

Exact circuit loading and speaker tap selection should be calculated using the applicable Edwards WG Series data sheet and the fire alarm system design.

Installation Information

The WGSVWF is listed for both wall and ceiling mounting. Edwards notes that WG appliances can be installed on recessed electrical boxes or suitable surface boxes, with appliance wiring completed from the room side.

Typical installation includes mounting the appropriate outdoor-rated box or adapter, connecting the speaker and strobe circuits, selecting the desired speaker tap and 15/30 cd setting, installing the appliance, and verifying voice, strobe, synchronization, and circuit supervision functions.
