Federal Signal's Model 400R audible/visual signal combines the effective warning of a rotating light with an optional Federal Signal Model 350 horn.
The Model 400R includes a large 4.25-inch diameter rotating reflector assembly for projecting light beams. The unit features an incandescent lamp that produces 60 flashes per minute.
Available in four dome colors: amber, blue, green and red.
The Model 400R is ideal for use wherever both audible and visual warning signals are needed. This rugged unit is excellent for industrial use and adaptable to most in-plant signaling needs.
A modern housing design makes the Model 400R suitable for use in institutional or non-industrial settings requiring an audible/visual alarm system, where heavy-duty industrial equipment might not be appropriate. Sounder/horn (Model 350) sold separately.
Special Considerations
- For audible signaling order optional horn and mounting kit
