TAKEX PA-470L 53' Wide Angle and 66' Long Range PIR Sensor

Takex, PA-470L, 53' Wide Angle and 66' Long Range PIR Sensor, Interchange Lens, Quad Element, Fuzzy Logic, Output Selectable - N/O N/C, 9 to 18VDC

Features:

• "Fuzzy Logic" is the state-of-the-art processing system that simulates the human decision process as it compares various information such as size, temperature differential, etc. to determine the criteria for an alarm condition. This reduces false alarm while maintaining a high detection capability.
• Wide angle / long range pattern is selectable during installation by convenient fresnel lens replacement. Spare long range lens is included in package. Zone changeover switch sets the detection pattern to match the lens pattern when lens is changed.
• When sensor detects a drop in supply voltage, the alarm relay and LED latches in alarm until voltage is restored to its proper level.
• Units contain special circuitry to indicate that an alarm has been activated during armed period. Especially useful when more than one unit is used per zone.
