In this case the infrared sensors APD-100 allows you to select one of three variants of sensitivity (low, medium, high), while in the model APMD-150 separately given 1 of 4 options for sensitivity to IR-channel and 1 in 8 channel options for the microwave. Due to the large consumption of microwave-head most of the motion sensors combined with infrared and microwave sensor considered ineffective. But unlike them, APMD-150 supports two-way communication, allowing the microwave head turns only when the controller triggers infrared motion sensor. Moreover, if the microwave sensor does not confirm alarm, infrared sensor will regard this event as false, and the system returns to normal operation. Another distinctive feature of new products is the possibility of replacing the lens to increase their range. The standard Infrared sensors APD-100 is equipped with ultra wide-angle lens (EWA) with a viewing angle of 141,2 and a range of 15 m. If required, this sensor can be placed one of two lenses with vertical blinds (range 22.5 m, width 2.2 m ) or a lens with a range of of 30 m and a width of 3m principal ray.
When choosing a lens sensor we recommend that the following rule: the amount of space on the main direction of motion detection should not be less than one third of the distance IR sensor. As a source of supply for APD-100, and 150 are used APMD-CR123A 3V lithium batteries in that ensure stable operation over three years, provided that part-time infrared sensors are not active, but their frequency Poll controller is less than 1 every 12 seconds. Install motion sensors is recommended within the zone of visibility ACU-100 controller. To minimize the risk of accidental masking people, all the sensors and detectors Alarm ABAX recommended to install as possible. To register, radiant heat infrared sensors use a dual pyroelectric element, capable of detecting the difference in temperature between the body and temperature of the background of a few tenths of a degree. Reciprocal subtraction of signals from the two pyroelectric element sensor to filter out noise when convection or air movement coming from the electrical and heat sources. In addition, motion sensors serve two-factor analysis of the signal: the value and quantity, and the thresholds of IR sensors are floating and change synchronously with the signal interference.
New wireless infrared sensors already on the Russian market, and the retail price of APD-100 and APMD-150 is $ 65 and $ 88 respectively.
