Active Infrared Detector 4 Bands 250m


Specifications

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

---Design  Durability Highly  Durable  and  Heat-Resistant  Housing Cover and Chassis

The  housing  cover  and  chassis  provide  higher durability against  shocks ,

high temperatures , and  many  other  harsh  environmental conditions 

---Frost  and  Dew Protection An anti-frost and convex visor design  is incorporated to

protect detector from effect  of frost and  dew 

---99.5% Beam  Blocking Stability Stable operation is maintained with  as much as

99.5% of the beam's   energy  blocked by heavy  rain , dust storm , snow frog

---High Grade Aspherical  Lens The high grade lens creates more sharply defined

nd precise infrared beams  compared to  ordinary  Fresnel  lenses 

---Twin   Sychorized  Pulsed  Beam Designed  for  Great  Stability" And  Gate "

dual  beams require simultaneous interruption of both beams to trigger an activation .

No activation is generatedwhen a bird or falling leaves break just one beam

---Adjustable Beam Interruption Period The  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 difficult mounting situations .

In the receiver there is a LCD  Voltage Displayer , it indicates the alignment leve
-A.G.C.( Automatic  Gain Control )Circuit TheA.G.C.Circuit  continually monitors

for gradual changes in the signal's strength caused by changing weather .It adjusts the

sensitivity accordingly to maintain proper signal level for the current environmental conditions.
