Voltage Display multi Beams Photoelectric infrared detector introduction

 

The CJ-DB 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 invisible infrared beams with shifting frequencies to the receiver. The frequencies change within a certain range to protect the beams from disturbance.
The changing frequencies feature can also help cut power consumption to extend the detectors life span.
The quick alignment system built-in is intended to speed up accurate and reliable positioning. This detector uses 2 pulsed infrared beams that are designed to activate an alarm only when both beams are simultaneously blocked.

 

_^--- 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 the 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 storms, snow or fog.

 

_^--- High Grade Aspherical Lens

 

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

 

_^--- Twin Synchronized Pulsed Beams Designed for Greater Stability

"And Gate" dual beams require simultaneous interruption of both beams to trigger an activation. No activation is generated when a bird or falling leaves break just one beam. 

 

_^--- Adjustable Beam Interruption Period

The Beam Interruption Time (the amount 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
