The sensor uses patented 4D signal processing technology to evaluate whether the size, speed, shape, and duration of an incoming signal match that generated by a human.
MacMall Part #: 7477291
Manufacturer Part #: GEC-AP669
The AP669 Ceiling Mount PIR with Dual Optic Technology incorporates two independent pyros, two separate ASICs and two 180° mirrors that provide two independent 180° fields of view. This design enables the detector to substantially increase the overall volume of its coverage area, providing superior detection performance and enhanced false alarm immunity. Combining 4D signal image processing with the dual mirror optical system, the AP669 analyzes the size, shape, duration and speed of incoming signals, and actually adapts the alarm threshold when faced with harsh environments. The two separate 180° mirror segments provide additional flexibility by enabling one of the 180° mirror segments to be shunted. One half of the coverage pattern is eliminated simply by programming a dip switch located in the back of the sensors housing. Unlike other ceiling-mount PIRs, the AP669s patented mirror optical system yields 18 solid curtains that cover the room with detection. The curtains emanate from the detector's ceiling-mount position to the floor below and out 30 feet in all directions for maximum coverage at all mounting heights up to 16 feet. The AP669s rotating base allows installers to shift the entire protection pattern by 15° in either direction for easier aiming.
Two 180° mirror segments, two pyros, and two custom integrated circuits provide superior detection and enhanced false alarm immunity 180° shunt gives flexibility to use only one half the units field of view when necessary 18 full curtains provide detection at all mounting heights, from 8 to 16 feet (2.4 to 5 m) Head and base unit rotates 15° in either direction for easier aiming Adaptive 4D signal processing analyzes size, speed, shape, and duration of signal 60-ft. (18 m) diameter with 360° coverage Tamper contact
