Orbit FA-4BC – Frequently Asked Questions

1) Will the Orbit FA-4BC fit a standard 4-inch square electrical box?
Yes. The FA-4BC is sized for standard 4 x 4 inch square box openings, so it drops onto the usual 4" square boxes used for fire alarm device rough-in. It is a flat blank, so it sits flush to the wall or ceiling with no raised profile.
2) I removed a pull station and need to close off the box. Is a blank cover the right part?
That is exactly what the FA-4BC is for. It is a blank, no knockouts or device openings, used to cap a spare or decommissioned fire alarm box so the opening is closed and finished. If you still need to mount a device or run a wiring device through the box, you want a cover with the matching device prep instead, not a blank.
3) What is the difference between the Orbit FA-4BC and the Mulberry 11700 blank cover?
Both are galvanized steel blank covers, but they close out different openings and read differently in the field. The Orbit FA-4BC is a 4 inch x 4 inch square blank cover powder-coated Red, the color convention used to identify fire alarm system components. The Mulberry 11700 is an F-35 Series oval/round blank cover in a 3/4 inch size, so it suits a small round or oval device opening rather than a 4 inch square box. If the box in the wall is a standard 4 inch square fire alarm box, the FA-4BC is the matching plate; for a small round outlet body opening, the oval/round cover is the one that lands.
4) Why is this fire alarm box cover red, and does the color matter for inspection?
Red is the standard color convention for fire alarm system components, so a red cover tells an electrician or inspector at a glance that the box behind it belongs to the life safety system rather than power or low voltage. The FA-4BC's red is a powder-coated finish over galvanized steel, not paint applied in the field, so it holds up to handling and wear.
5) Can a plain galvanized blank cover be used in place of the Red Orbit FA-4BC on a fire alarm box?
They are not interchangeable in appearance or in opening size. The Orbit FA-4BC is finished in Red specifically so electricians and inspectors can identify the box as fire alarm system equipment, and it is a flat 4 inch square cover. The Mulberry 11700 is an unpainted galvanized steel cover and is an oval/round shape in a 3/4 inch size, so it neither covers a 4 inch square box nor carries the Red identification. Where the spec or the inspector expects fire alarm components to read Red on a 4 inch square box, the FA-4BC is the cover written for that condition.
6) Is a galvanized steel cover suitable for damp or industrial areas?
The FA-4BC is galvanized steel with a powder-coated topcoat, which gives corrosion resistance plus protection against scratching and chipping. Orbit lists it for commercial, industrial, and institutional installations. For wet locations you would still match the cover to a box and gasket rated for that environment.
7) What part number do I order for the Orbit 4-inch red fire alarm blank cover?
Order Orbit FA-4BC. It is offered in the one 4" size, so there is no finish or configuration to specify beyond that part number.
