Orbit Industries FA-UMAB Fire Alarm Mounting Box 4 in Square

Product Description

The ORBIT INDUSTRIES FA-UMAB is a universal mounting adjustable box designed for fire alarm installations. Built to a 4-inch square footprint with a 3.5-inch depth, this steel rough-in box includes a built-in adapter that allows the mounting position to adjust from 0 to 1.5 inches, accommodating variations in wall or ceiling finish depth. It is installed by licensed electricians and fire alarm contractors during new construction or retrofit projects where a consistent, flush-mount device presentation is required.

The FA-UMAB is suited for commercial and residential fire alarm system rough-in work. Its adjustable adapter makes it practical in applications where finished surface depth is not fixed at the time of box installation, such as drywall or drop-ceiling environments. The square format accepts standard 4-inch device covers and fire alarm accessories.

Key Features

• 4-inch square footprint with 3.5-inch depth for standard rough-in clearance
• Built-in adapter adjusts from 0 to 1.5 inches to accommodate variable finished-surface depths
• Universal mounting design fits a range of fire alarm device configurations
• Accepts standard 4-inch square device covers and trim rings

Compatibility

Designed as an OEM-style replacement and new-installation mounting box for fire alarm devices requiring a 4-inch square rough-in enclosure with adjustable depth capability.

Installation Notes

Installation should be performed by a licensed electrician or fire alarm contractor in accordance with NFPA 72 and applicable local codes. Power down and lock out all related circuits before beginning work in the rough-in area. Confirm finished-surface depth before setting the adjustable adapter position to ensure the device face will sit flush. Do not exceed the 1.5-inch maximum adjustment range of the built-in adapter.
