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.
