PHOTOELECTRIC DETECTOR
		The AN900-D series are quad photoelectric detectors with selectable designed to provide reliable perimeter security both indoors and Outdoors. It consists of separate transmitters and receivers. The transmitter emits invisible infrared beams with selectable frequencies to the receiver. The selectable beam frequencies can be used to avoid unwanted cross talk that can occur when using multiple photo beams for long distance or beam stacking applications. Quick alignment system is built-in to speed up accurate and reliable positioning. This detector uses 4 pulsed infrared beams that are designed to activate an alarm only when both 4 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.
High Grade Aspherical Lens The high grade Aspherical lens creates more sharply defined and precise infrared beams compared to ordinary fresnel lenses		Quad Synchronized Pulsed Beams Designed for Greater Stability It requires simultaneous interruption of all beams to trigger an activation. No activation is generated when a bird or falling eaves break just one two or three beams
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
Selectable 4-Channel Beam Frequencies The selectable beam frequencies can be used to avoid unwanted cross talk that can occur when using multiple photo beams for long distance or beam stacking Applilcations. 2Beam stacking 2Beam long distance stacking

Quick optical and voltage alignment with10LEDs to speed up positioning A removable viewfinder allows for easyalignent even in some of the most difficult mounting situations. In the receiver there are 10 LEDs and two jacks for quick and accurate alignment. The rotating dial and voltage measuring allows the installer to finely adjust the beam easily horizontally (180/ +90) or vertically (20/ +10) until suggested lit LEDs or value are obtained. The upper two beams and lower beams can be adjusted separately or simultaneously. 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
