Honeywell Home Proseries Smoke Detector Coverplate is a protective plate designed for Proseries Smoke Detector and Proseries Heat Detector. It improves aesthetics by covering up any old paint color or screw holes No need to spackle or repaint the heat and smoke detectors over again, allowing cleaner installation. It installs over previously installed, ceiling/junction box or a new install. This product features a Gasket with a sticker that says “WARNING! DO NOT REMOVE GASKET” which minimizes airflow from larger holes and reduces the chance of a stack effect that could interfere with smoke detector performance. The Stack Effect occurs when there is airflow in the ceiling or wall cavity that the smoke detector is mounted on that negatively impacts the entry of smoke into the optical sensing chamber.

The Honeywell Home Proseries Smoke Detector Coverplate has a diameter of 5.8 inches (14.7cm) which is perfect for smoke and heat detectors that have a circumference of about 4.25 inches (36.19cm) with a 4.5-inch (11.4cm) diameter. It not only allows clean installation of the devices, but it also provides superior protection to the heat sensor and smoke detectors.
