The AN900-A 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 invisi ble infrared beams with changing freque ncies to the receiver. The frequencies change In a certain range to protect beams from disturbance. The changing frequencies feature can also help cut power consumption to extend the detectors life span. Quick alignment system is built-in to speed up accurate and reliable positioning. This detector uses 2 pulsed infrared beams that are designed to activate an alarm only when both 2 beams are simul taneously 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.
High Grade Aspherical Lens The high grade Aspherical lens creates more sharply defined and precise infrared beams compared to ordinary fresnel lenses		99.5% Beam Blocking stability Stable operation is maintained with asmuch as 99.5% of the beam's energyblocked by heavy rain,dust storms,Snow or fog.
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

Quick optical and voltage alignment to speed up positioning A conveniently placed viewfinder allows for easyalignent even in some of the most difficult mounting situations. In the receiver there are two holes indicating for voltage measuring.Fine the beam and use a voltmeter to measure the voltage until the suggested value appears. The rotating dial and voltage measuring allows the installer to finely adjust the beam easily horizontally (+180/ +90) or vertically (+10/ + 5). A.G.C. (Automatic Gain Control) Circuit The A.G.C. Circuit continually monitors forgradual changes in the signal's strength caused by changing weather conditions. It adjusts the sensitivity accordingly to maintain the proper signal level for the current Environmental conditions DIMENSIONS
