TriTech PIR/Microwave Intrusion Detectors with Pet Immunity

1.0Description

The DS820i and DS820iT Series are high performance TriTech Passive Infrared (PIR)/Microwave (MW) Intrusion Detectors which use advanced signal processing to provide outstanding catch performance and unsurpassed false alarm immunity. They are designed to detect movement of a human body in the interior of a structure as it moves across the Detector’s field of view. When motion is detected, the Detector sends an alarm signal to the control panel. With Bosch Security Systems Pet Friendly® pet immunity, these Detectors will not detect a dog up to 100 pounds (45 kg) or two 60 pound (27 kg) dogs, up to 10 cats, numerous rodents or flying birds. This pet immunity feature has not been tested by Underwriters Laboratories.
