The Siemens ZB-R is a red mounting back box for Z-series notification appliances. Specifically, it provides the surface-mount enclosure that Z-series horns, strobes, and horn/strobes attach to. As a result, installers get a clean, code-style mount on wall surfaces without a recessed electrical box.
Siemens ZB-R quick facts
- Color: red, matching standard Z-series notification appliance trim
- Designed for surface mounting where flush mounting is not possible
- Used with Z-series notification appliances
- Siemens part reference: 500-636193
Selecting the right back box
Z-series appliances offer both flush and surface mounting options. Therefore, only order the ZB-R when surface mount is required. For flush installations, the standard 4-inch square back box behind the wall is typically used instead.
Before ordering
Confirm the appliance series. The ZB-R is paired with the Siemens Z-series notification family. Other Siemens notification lines use different back boxes.
