ADT Ceiling Mount Motion Detector Hardwired  is a wired passive infrared motion detector that is designed to be mounted on the ceiling of a room. You should mount this detector on the ceiling in the center of the protected area, between 8’ and 12’ high, for optimal performance. A ceiling-mounted motion detector helps minimize vandalism, especially when being used in a public place. Smaller and more streamlined than a smoke detector, the ADT Ceiling Mount Motion Detector Hardwired is an ideal choice to protect an interior space with minimal visual detraction.

This detector is best for rooms no larger than 30’ x 30’. If you use it in a space larger than that, such as a lobby, warehouse, classroom, or any other larger area, you should use multiple motion detectors to achieve adequate protection. When mounted on a ceiling at 11’ high, it has a 360 degree lookdown view that covers an area of 36’ in diameter. For easy mounting, maintenance, and removal, this detector has a twist off front cover.

To assist with different sensitivity requirements, and to cut down on false alarms the motion detector is has a selectable pulse count which you can easily change by installing or removing a jumper pin. You should not install this detector in areas that may be prone to rapid temperature change, close to heating and cooling systems, or in direct sunlight.

When mounting on the ceiling, ensure that the coverage pattern is largely unobstructed by large items. The passive infrared PIR technology requires that a moving person be in the direct field of view of the detector. So always walk test your motion to ensure that it’s covering the area you expect. This detector is the ideal solution for hardwired security systems that require a motion sensor in a central location that is not easily recognizable as a security device.
