Automated Lighting Management for commercial buildings

Energy savings and increased efficiency with the Finder Type 18.31 PIR movement detector

PRODUCT FOCUS

Amongst the solutions designed for areas of increased activity, and spaces with high ceilings, the Finder Type 18.31 movement and presence detector, designed for indoor use, stands out as a benchmark device for designers and installers who need to combine wide areas of survey with electronic reliability.

The standard white version (suitable for surface mounting) has recently been joined by two anthracite grey variants (for both surface and recessed mounting), and is the ideal option for those seeking a product that seamlessly fits in with the most elegant contemporary finishes.

Featuring a single 10 A normally open (NO) contact, the sensor has two selectors that allow for the custom adjustment of the twilight activation threshold (from 5 to 350 lux), and the light off delay (from 10 seconds to 12 minutes), ensuring maximum comfort as people pass by.

One on the main distinguishing features of Type 18.31 is its sleek, ultra-flat lens, that makes the device unobtrusive

The Type 18.31.8.230.0032 version for high ceilings offers a wide area of survey with a sensing diameter of up to 12 meters. When installed at a height of 2.8 meters, it can detect even the slightest movement.

This feature allows for the coverage of large areas such as corridors, hotel lobbies, warehouses, waiting rooms, and open spaces. From a systems engineering perspective, such a wide range of application simplifies the electrical project design, reducing the number of cable runs and installation time.
