The Finder 18.51.8.230.B300 is a versatile PIR movement and presence detector with Bluetooth programming, designed for intelligent automatic lighting control in commercial, industrial and public buildings. Part of the Finder 18 Series, it combines passive infrared detection, ambient light sensing and configurable switching functions in a compact ceiling-mounted device.
Bluetooth connectivity enables convenient configuration from a compatible smartphone using Finder's programming ecosystem, simplifying adjustment of operating parameters without requiring direct manual access to the detector. This makes the 18.51.8.230.B300 particularly useful in modern building installations where commissioning flexibility, efficient maintenance and precise lighting control are important.
With a 110–230 V AC supply and a single-pole 10 A output contact, the Finder 18.51.8.230.B300 provides dependable switching for compatible lighting loads. PIR sensing and light-level control allow lighting to operate according to occupancy and available daylight, helping improve convenience while reducing unnecessary energy consumption.
PIR detectors sense changes in infrared radiation produced when people move through their detection area. The Finder 18.51.8.230.B300 uses this technology to automate connected lighting, allowing illumination to operate when required rather than remaining permanently switched on in intermittently occupied spaces.
The addition of Bluetooth configuration makes commissioning and adjustment more convenient. Operating parameters can be configured for the requirements of the installation, while integrated ambient light sensing allows the detector to take available daylight into account when controlling lighting.
