Smoke Alarm Magnetic Mount Adapter Plate

Many people mount smoke alarms using magnetic ceiling mounts instead of the original screw-mounted backing plate. These allow the alarm to be removed easily for battery changes without twisting or breaking plastic clips.

However, many modern smoke alarms include a small priming button that must be pressed by the original backing plate. If this button is not depressed, the alarm will turn off.

Magnetic mounting plates usually do not reach this button, which prevents the alarm from functioning properly. This model solves that problem.

How it works

This part is a replacement backing plate / shim that:

• slides into the same mounting slots as the original backing plate

• presses the safety button on the smoke alarm

• provides a flat surface for attaching a magnetic mounting plate

Once installed, you can attach the magnetic plate and mount the alarm normally.

Result

You get the convenience of a magnetic smoke alarm mount while still satisfying the alarm's built-in mounting safety switch.

No twisting, no broken clips - just pull the alarm down when you need access.

Installation

1. Insert this adapter plate into the same slots as the original backing plate

2. Attach the magnetic steel plate to the adapter

3. Mount the ceiling plate and snap the alarm into place magnetically
