The Honeywell 997 is a wired passive infrared motion detector that is designed to be mounted on the ceiling of a room. The Honeywell 997 should be mounted 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 997 is an ideal choice to protect an interior space with minimal visual detraction.
The Honeywell 997 ceiling mount motion is best suited for rooms no larger than 30’ x 30’. If used in a space larger than that, such as a lobby, warehouse, classroom, or any other larger area, it is recommended to use multiple motion detectors to achieve adequate protection. When mounted on a ceiling at 11’ high, the 997 has a 360 degree look-down view that covers an area of 36’ in diameter. For easy mounting, maintenance, and removal, the Honeywell 997 is equipped with a twist off front cover.
To assist with different sensitivity requirements, and to cut down on false alarms the 997 motion detector is equipped with selectable pulse count which can easily be changed by installing or removing a jumper pin. The 997 should not be installed in areas that may be prone to rapid temperature change, close to heating and cooling systems or in areas that expose the detector to direct sunlight. When mounting on the ceiling, ensure that the coverage pattern is largely unobstructed by large items, such as plants, curtains, screens, or large pieces of furniture. The passive infrared PIR technology requires that a moving person be in the direct field of view of the 977, so always walk test your motion to ensure that it is covering the area you expect. The Honeywell 997 ceiling mount motion 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.
