theben thePrema S360 KNX UP BK Presence Detector (2079502)

Description

Introduction

The theben thePrema S360 KNX UP BK (Item no. 2079502) is a passive infrared (PIR) presence detector engineered for flush-mounted ceiling installation in KNX building control systems. Featuring a square 360° detection zone, this sensor delivers efficient occupancy coverage up to 49 m² (7 x 7 m) at a standard mounting height of 3 m. This device is part of our KNX system devices range.

Equipped with 2 independent lighting channels and 2 presence channels, the device connects directly to the KNX bus line via standard KNX terminals. It utilizes integrated mixed light measurement to optimize lighting control based on natural daylight levels across commercial and residential automated spaces.

Key Features

• Passive infrared (PIR) sensing mechanism with 360° square coverage pattern.
• Ceiling flush-mounted housing designed for clean integration into modern ceilings.
• Direct KNX bus connection using standard KNX bus terminals.
• Configurable presence switch-on delay from 10 seconds to 30 minutes, or inactive.
• Defined coverage areas for seated activities across 2.0 m, 2.5 m, and 3.0 m mounting heights.
• Documented GWP Cradle-to-Grave environmental performance of 13.86 kg CO₂ eq.

Benefits

• Provides 360° square detection coverage up to 49 m² (7 x 7 m) at a 3 m mounting height.
• Includes 2 light channels and 2 presence channels for granular automation control.
• Utilizes mixed light measurement to accurately adjust artificial lighting against available daylight.
• Supports configurable light switch-off delays ranging from 30 seconds to 60 minutes.
• Offers extended presence switch-off delay options from 10 seconds up to 120 minutes.
• Transparent lifecycle environmental data with GWP Cradle-to-Gate rating of 3.9 kg CO₂ eq.
