PASSIVE INFRARED SENSOR
PA-4820 LONG RANGE

Feature

ORIGINAL QUAD ELEMENT + NEW SIGNAL PROCESSING (FUZZY LOGIC)

TAKEX original quad pyroelectric sensor improves sensitivity. This newly developed original pyroelectric sensor coupled with new Fuzzy Logic provides high catchability.

MIRROR OPTICS AND EASY AIMING SYSTEM

Precise mirror optics and new quad element assure high sensitivity and high reliability. As mirror and head unit move together, area adjustment does not reduce/blur sensitivity. TAKEX original view finder assures precise and quick adjustment.

TROUBLE ALARM

Unit monitors the following functions. When a trouble condition is detected, the alarm LED lights and trouble alarm is initiated.
Unit trouble ... A trouble alarm triggers when inner circuitry/wiring is damaged/broken.
Low voltage ... A trouble alarm triggers when sensor detects a drop in supply voltage.
Failure to replace... A trouble alarm triggers when head unit is not replaced after adjustment is completed.

FINE MOTION DETECTION

Unit can be adjusted from quad element sensing to two twin element by built - in switch for situations where close range detection is desirable.
* Alarm LED disable (ON / OFF)
* Alarm contact changeover (N.C. / N.O.)
* Sensitivity adjustment (60%, 80%, 100%, 120%)

ALARM MEMORY

Units contain special circuitry to indicate an alarm has been activated during armed period. Especially useful when more than one unit is used per zone.

REMOTE LED CONTROL

Allows the LED to be enabled/disabled via the control panel.
