The Optex BX-80N BOUNDARYGARD Outdoor PIR Detector detects infrared heat energy that is emitted by humans and protects a building's exterior by detecting intruders before an entry is attempted. In addition to signaling an alarm system, the BOUNDARYGARD can create an audible local alarm to detect intruders before a break-in occurs. With long, narrow detection areas that extend from both its sides, the detector is specifically designed to be wall-mounted centrally on a building, covering the building perimeter with a multi-layered, horizontal barrier. To help reduce false activations, the range can be adjusted so that detection extends only to the end of the building. The unit also has a size-judging function, which helps it discriminate between large and small objects within the detection area. This invisible barrier offers the first line of defense to a property's boundary.
Variable detection range from 6.5 to 39.4' (2.0 to 12.0m) on each side creates a narrow 78.7' (24.0m) long detection area that protects wide horizontal areas, such as a building's perimeter.
Double conductive shielding reduces false alarms caused by unwanted light and RFI sources such as car headlamps or reflected sunlight.
Advanced temperature compensation automatically increases the detector's sensitivity under high temperature conditions, especially where the background temperature ranges from 95.0 to 98.6°F (35.0 to 37.0°C), which is close to a human body temperature.
With the Limited detection range function the detection range can be adjusted to avoid unwanted objects. As both the upper and lower fingers have to be simultaneously blocked to activate the detector, the detection range of the BX-80N can be limited to avoid detecting unwanted objects.
Size judging function triggers alarms only when upper and lower detection layer detect movements.
The BX-80N features the audible alarm indicator and walk test. The detector's built-in buzzer can sound an alarm while it is occurring. This buzzer can also be used to annunciate detection during walk test.
