Description

The WL4 AIR-BH250-L4 is an active infrared (AIR) universal detector set for outdoors and indoors with 4 beams and a maximum distance of 250m (outdoors). The set consists of a transmitter and receiver that must be wired for power and the NO/NC relay connection. The WL4 AIR-BH250-L4 can be used as a detector for alarm systems, access control systems, smart home systems, an intercom system and, for example, to connect to the alarm input of an IP camera.

Possibilities

The WL4 AIR-BH250-L4 has 4 high-precision Fresnel lenses that can be adjusted with an angle of horizontal 180° (±90°) and vertical 20° (±10°). The alignment takes place with the built-in LED display. The detector set has a range of up to 250 meters outdoors and 750 meters indoors. The detection can be set when all 4 IR beams are broken or only the upper or lower 2 IR beams are broken.

The WL4 AIR-B60-2 has a tamper switch for removing the lens hood and has a NO/NC relay as an alarm output. The detector has digital filter technology against direct sunlight or, for example, car headlights. The detector has the ability to respond to different weather conditions such as fog, rain, snow and frost to minimize false alarms. The detector is weatherproof (IP65).

Installation

The WL4 AIR-BH250-L4 can be mounted on a wall or pole. Post brackets are included. Under the 'Options' tab we have included suitable stainless steel mounting poles and an optional AIR-VWB mini heating element. Suitable 12VDC or 24VAC power supplies are included in the “Supplies / Power Supplies” category in our online store.
