Ademco IS2535 Passive Infrared Motion Sensor w/ selectable pet i

Our IS2535 family has switch selectable pet immunity. Whether using the high security/non-pet setting, the intermediate 18 Kg/40 lbs. mode or the large 36 Kg/80 lbs. setting, you have all the options in one unit.  Mounts on walls, in corners or on ceilings, with heights from 2.3-2.7 meters (7'6" to 9').  Two dip switches make it easy to adjust the sensitivity and adequately protect the premises. Four different security levels are available. Each setting modifies either the PIR pulse count or the alarm threshold, allowing the installer utmost flexibility when setting up their security alarm system.
