The Edwards GCSVWA-R Ceiling Speaker Strobe is an audible/visible emergency notification appliance designed for ceiling-mounted mass notification and emergency communication systems. Edwards identifies the GCSVWA-R specifically as a white ALERT-marked ceiling speaker/strobe with a red 15-candela visual signal.
The appliance combines a high-fidelity emergency speaker with a synchronized LED strobe, allowing voice instructions and visual emergency notification to be delivered from a single ceiling location.

15 Candela Red Strobe
The GCSVWA-R is specifically configured with:
Light Output: 15 candela
Visual Signal Color: Red
Housing Color: White
Marking: ALERT
Installation: Ceiling mount.
The red visual signal distinguishes this model from the standard clear/white FIRE versions in the GCSV family.
ALERT Notification
The A designation identifies the appliance as an ALERT-marked configuration.
Edwards’ model-number syntax identifies:
GCS: Ceiling-mount appliance
SV: Speaker/Strobe
W: White housing
A: ALERT marking.
The additional -R suffix identifies the model’s red visual signal.
This configuration is intended for emergency communication applications where signaling may extend beyond conventional fire-only notification.
High-Fidelity Speaker
The speaker portion of the GCSVWA-R is designed to provide clear emergency voice reproduction.
Published GCS Series specifications identify a speaker frequency response of:
400 Hz to 4,000 Hz.
This supports intelligible reproduction of:
- Emergency instructions
- Evacuation messages
- Alert messages
- Live paging
- Prerecorded announcements
The GCS Series is also designed for high speech intelligibility in emergency communication applications.
25V / 70V Speaker Operation
The GCSVWA-R speaker supports:
25 VRMS
or
70 VRMS
audio operation, selectable according to the emergency voice system configuration.
This allows the appliance to integrate with common distributed fire alarm and emergency communication speaker circuits.
Selectable Speaker Power
The speaker provides selectable power taps:
¼ W
½ W
1 W
2 W.
Published sound-pressure levels range from approximately 78 dBA at ¼ W to 87 dBA at 2 W under the specified UL test conditions.
The appropriate wattage is selected according to room acoustics, ambient sound levels, amplifier capacity, and required emergency voice coverage.
Emergency Communication Operation
The GCSVWA-R can be used as part of an Emergency Voice/Alarm Communication System (EVACS) or mass-notification system.
The speaker provides intelligible emergency instructions while the red strobe simultaneously provides a visual indication of the emergency condition.
This combination is useful for applications where occupants need both audible instructions and visible emergency notification.
Synchronized Strobe Operation
The GCSVWA-R supports synchronized visible notification when operated from compatible Edwards synchronization equipment.
Published GCS Series specifications allow a maximum synchronization wiring resistance of:
20 Ω between any two devices.
Synchronization coordinates multiple strobes so that appliances within the same field of view flash together.
LED Strobe Technology
The GCS Series uses high-performance LED strobe technology.
Edwards identifies benefits including reduced device current consumption, which can permit more notification appliances per circuit and reduce overall power requirements compared with older strobe technologies.
For the standard GCS strobe circuit, published operating voltage is:
16–33 VDC
or
16–33 VFWR.
Conventional Notification Operation
The GCSVWA-R operates as a conventional speaker/strobe rather than an individually addressed Signature device.
Its functions connect to separate system circuits:
Speaker Circuit: Emergency audio
Strobe Circuit: Visual notification
The appliance itself does not require a Signature device address.
Electrical Information
Strobe Operating Voltage: 16–33 VDC or 16–33 VFWR
Visual Output: 15 cd
Visual Signal: Red
Notification Type: Audible / Visible
Mounting: Ceiling
Housing: White
Marking: ALERT.
Room-Side Wiring Plate
The GCSV Series requires the:
GRSW-10 — Room Side Wiring Plate, 10 pack
which Edwards identifies as required and ordered separately.
The room-side wiring arrangement allows field conductors to be terminated before the finished speaker/strobe appliance is attached.
Additional accessories include:
GCTW: White trim plate
27193-26: White two-gang surface-mount box.
Installation Information
The GCSVWA-R is designed for ceiling installation. Typical installation includes mounting the required room-side wiring plate, connecting the speaker and strobe circuits, selecting the required 25V or 70V audio setting, selecting the appropriate speaker wattage, and attaching the speaker/strobe.
After installation, the emergency communication system should be tested to confirm proper speaker output, voice intelligibility, red strobe operation, synchronization, and circuit supervision.
