Skorpion tm PHOTOELECTRIC DETECTOR   Skorpion tm    Contact Us customer service technical supportLive Chat   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 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.   High Grade Aspherical Lens The high grade lens creates more sharply defined and precise infrared beams compared to ordinary Fresnel lenses.   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.   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 Top Quick optical and voltage alignment to speed up positioning A conveniently placed view finder allows for easy alignment, even in some of the most difficult mounting situations. In the receiver there are two holes indicating for voltage measuring. Find 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 for gradual 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   SPECIFICATIONS MODEL AN900-A30 AN900-A60 AN900-A80 AN900-A100 Detection method Pulsed Infrared Dual Photo-Electric Beam Range Outdoor 30m 60m 80m 100m Indoor 90m 180m 240m 300m Beam Options   'Triplicate' Pulsed Beam,   'Quad' Pulsed Beam   & 'Quad' Pulsed Beam w/Variable Frequency  (outdoor ranges from 30m up to 250m) Interruption period 50~700msec(selectable) Power input DC12~24V/AC11~18V Current consumption 40mA max 55mA max 65mA max 65mA max Alarm period 2Sec(±1)nominal Alarm output Form C relay (AC/DC30V 0.5A max) Tamper switch Normally Closed.
