System Sensor SBBGRL Sensor Surface Mount Back Box.

System Sensor SBBGRL — Compact Wall Surface-Mount Back Box (Red)

The System Sensor SBBGRL is a compact surface-mount back box accessory designed for use with System Sensor L-Series wall-mount notification appliances such as horns, strobes, and horn-strobes. It provides a secure, hard-surface mounting solution when recessed mounting isn’t feasible — for example, on concrete, brick, or finished drywall surfaces.

Key Features & Benefits

• Surface-Mount Solution: Allows wall devices to be mounted flush on solid surfaces where an electrical box is not easily accessible.

• Compact Footprint: Sized for compact L-Series notification devices, minimizing visual impact while housing the device securely.

• Durable Construction: Designed for indoor use, it includes a grounding plate with a screw and threaded knockouts for conduit entry to aid wiring and grounding.

• Color – Red: Matches typical life-safety installations with a red finish for fire alarm devices.

Typical Applications

• Used in commercial, institutional, and industrial buildings to surface-mount notification appliances on solid masonry or other non-backbox surfaces.

• Ideal for retrofit and renovation projects where flush mounting isn’t practical.
