Narrow detection, vertical or horizontal mount

AP-20NB is suitable for a wide range of commercial and residential applications. In vertical mount it works by creating a narrow detection area and alerting of movement close to windows or doors. In horizontal mount it can create a plane detection area ideal to protect corridors or ceilings.

Discreet recess-mount installation

The AP-20NB automation sensors can be installed with a recess mount both on walls and ceilings for seamless blending with its surroundings. We also offer a recessed mount with an 86 type box installation using the included decorative plate. To adapt seamlessly in any site, the AP-20NB has flexible ceiling mounting height of 2.5 to 4.5meters.

Adjustable detection sensitivity

With adaptability in mind, the AP series' sensitivity can be adjusted to low, medium or high, depending on the needs of the environment.
