Description
Introduction:
A motion sensor (passive-infrared or PIR) detects movement within a specific area by sensing the infrared energy emitted from a body as it moves across the sensor’s field of view. When this motion is detected, the sensor transmits an alarm signal to the control panel.
Use a motion sensor to protect locations where door/window sensors are impractical or not needed. For example, use a motion sensor to protect large areas or open floor plans. Motion sensors also provide backup protection for door/window sensors.
Alarm Processing:
The RF-ARPIR-345-NN utilizes advanced signal processing, and a top-quality infrared detector. Next, a patented modern DSP ASIC directly converts the infrared detector signal into digital form, for best reliability and stability.
Pet Immunity: The RF-ARPIR-345-NN is designed to allow the presence of pets (up to 22 lbs.) without signaling an alarm. It includes a special micro-element lens array that produces much stronger optical signals for humans than for pets 22 lbs. or lighter.
NOTE: Pets come in many varieties. Some pets (especially larger ones with very short hair), even if lighter than 22 lbs. may produce enough infrared radiation to cause alarms. RF-ARPIR- 345-NN users are strongly advised to test the sensor with their own pets, in order to verify that the detector will not signal an alarm when their pets are moving within its fields of view.
