Zephyr's Market Adapter Plate for X-Sense Smoke & CO Alarms, Universal Fit

Give your new X-Sense alarm a finished, factory look on any existing ceiling or wall box.

Older smoke and CO detectors were often wider than the compact alarms X-Sense sells today, which can leave exposed paint, old screw holes, or a mismatched ring of ceiling around your new alarm. This retrofit adapter plate mounts between your existing electrical box and the bracket that ships with your X-Sense alarm, covering that gap for a clean, finished install.

One Universal plate is sized to work across X-Sense's smoke, CO, and combination alarm lineup. The alarm-side face includes both 2-hole and 3-hole pilot patterns, covering compact models like the XS01 series as well as larger combo and CO models. You mount your alarm's own bracket to the plate exactly as you would to a ceiling box.

The box side has 6 counterbored screw slots sized for the most common electrical box patterns: 3.5" round or octagon boxes, standard single-gang boxes, and 4" octagon boxes. A center opening keeps your wiring and wire nuts accessible after the plate is installed.

What's included: 1 adapter plate, printed in durable PETG plastic, and a set of short self-tapping screws sized for the plate.

• Universal fit for X-Sense alarms: One adapter plate covers both 2-hole and 3-hole mounting brackets used across X-Sense smoke, CO, and combination alarms, so you don't have to guess which plate matches your detector.
• Covers older junction boxes: 6 counterbored slots on the back fit 3.5" round, 3.5" octagon, single-gang, and 4" octagon boxes, hiding the larger footprint left by an older detector.
• Cleaner look, less patching: New X-Sense alarms are smaller than many older smoke detectors. This plate covers exposed ceiling paint, old screw holes, and box edges so you don't have to patch or repaint.
• Simple self-tapping install: Includes short self-tapping screws sized for the plate. Attach the plate to your existing box, then mount your X-Sense alarm's own bracket to the plate as usual.

Note: Zephyr's Market is an independent accessory manufacturer. This plate is designed to be compatible with alarms sold under the X-Sense brand but is not manufactured, sold, or endorsed by X-Sense, and X-Sense has not authorized this listing. The plate is a cosmetic and mechanical mounting accessory only; it is not part of, and does not alter, the UL listing of your smoke or CO alarm. Always follow your alarm manufacturer's installation instructions and local electrical code.
