PRINCIPLE OF OPERATION: The optical system divides the area into a series of protective zones. A special When an intruder sensor measures the level of far infrared energy in each zone. crosses or enters any zone the resulting change in infrared energy is detected and an alarm condition will exist. The sensor does not respond to visible perature of the room.

up to 20°.
The optical system has been designed to give proper coverage'based upon a typical mounting height of 7'. However,.the unit may be mounted at any height between 7' and 9' to achieve a proper 30' pattern. If the unit is to be mounted higher than 9', perhaps as high as 12', or it it is desired to obtain a range of less than 30' for a particular installation, the optical head may be tilted downward. Combinations of mounting height and "tilt" can be used to obtain coverages as shown in Diagram 3. To adjust the tilt of the optical head, grasp the metal casting firmly between thumb and index finger at both sides (where a ridge is provided): pull gently forward until assembly is free, then set the tabs on the casting into the desired notches on the bracket and release. See Diagram 2. IMPORTANT: Do not touch the reflector or sensor surfaces.

"Dead" Zone Caution: Note in Diagram 3 that for several tilt position/mounting height combinations there are indicated "dead zones" within which a person could be moving and not be detected by any of the unit's coverage zones. In general, these dead zones are apt to be present as the unit's mounting height is increased and its coverage pattern is tilted downward. SELECTIN A MOUNTIN LOCATION: The No. 655 Passive Infrared Motion Detector responds to changes in energy which occur when an intruder moves into or out of a zone. Best coverage will be obtained if the mounting site is selected such that the likely direction of intruder motion is ACROSSthe pattern. See Diagram 4a, b and c.

Before any equipment is returned to Ademco for service, a Return Authorization Number should first be obtained from the nearest Ademco Distribution'center. If it becomes necessary to return a unit for repair, the optical head and reflector assembly within the unit should be cushioned by surrounding it with soft packing material (such as tissue, newspaper, foam or plastic bubbles) to protect it from undue stress during shipment. Take care not to touch the reflector or sensor surfaces.
