Detailed Product Description

Voltage Display multi Beams Photoelectric infrared detector introduction

The XA-D series are dual photoelectric detectors designed to provide reliable perimeter security both indoors and outdoors.

It consists of separate transmitters and receivers,The transmitter emits invisibke infrared beams with shifiing frequencies to the receiver ,the frequencies change within a certain range to protect the beams from disturbance.

The changing alignment system built-in is intended to speed up accurade and reliable positioning ,This detector uses 4 pulsed infrared beams that are designed to activate an alarm only when all beams are simultaneously blocked.

-Design Durability

Highty Dutable and Heat-Resistant Housing Cover and Chassis

The housing coverand chassis provide higher qurability against shocks,high temperatures ,and many other harsh enviromental conditions

-Frost and Dew Protection

An anti-frost and convex visor design is incorporated to protect the detector fron effect of frost and dew

-9.95% Beam Blocking stability

Stable operation is maintained with as much as 99.5% of the beams energy blocked by heavy rain ,dust stoms,snow or fog

_High Grade Asherical lens

The high grade lens creates more sharply defined and precise infrared beams compared to ordinary Fresnel lenses

-Twin Synchronzied  Pulsed Beams Designed for Greater Stabllity

"And Gate "dual beams require simultaneousinterruption of both beams trigger an activation .No actovation is genereted when a bird or falling leaves break just one beam.

-Adjustable  Beam interruption Time (the mount of time a beam must be broken for an alarm to occur)can be adjusted to fit any application ,For example ,when protecting a wall or fence ,a longer interruption time will catch intruders ,but let jumping cats pass through without setting off an alarm

-Quick optical and voltage alignment to speed up positioning

conveniently placed view finder allows for easy alignment ,even in some of the most diffcult mounting situations ,In the receiver there is a LCD Voltage displayer .It indicates the alignment level.

-AGG(Automatic Gain Control )Circuit

Yhe AGC Dircuit continually monitors for gradual changes in the signals strength caused by changing weather conditions ,It adjusts the sensitivity accordingly to  maintain the proper signal level for the current envirmental conditions
