| The SY-MAD is a wired  passive infrared motion detector that is designed to be mounted on the ceiling  of a room. The SYAC SY-MAD should be mounted on the ceiling in the center of  the protected area, between 7’ and 13’ 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 SY-MAD  is an ideal choice to protect an interior space with minimal visual detraction.                     The SYAC SY-MAD  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, vault, or any other  larger area, it is recommended to use multiple motion detectors to achieve  adequate protection. When mounted on a ceiling at 11 feet high, the SY-MAD has  a 360 degree lookdown view that covers an area of 36 feet in diameter. For easy  mounting, maintenance, and removal, the SYAC SY-MAD is equipped with a twist off  front cover.                     To assist with  different sensitivity requirements, and to cut down on false alarms the SY-MAD  motion detector is equipped with selectable pulse count which can easily be  changed by installing or removing a jumper pin. The SY-MAD 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 SY-MAD, we recommend you  test the motion sensitive areas. The SYAC SY-MAD ceiling mount motion detector  is the ideal solution for hardwired security systems that require motion sensors  in a central location . |
