ELSNER 70672 Intra-Sewi KNX L-Pr- intense black RAL 9005 Recessed presence detector with light sensor

The Intra-Sewi KNX L-Pr presence detector, code 70672, is a device designed for integration into the KNX building bus system. This product combines the detection of the presence of people with the measurement of ambient light.

Key Features

The detector uses a passive infrared (PIR) sensor to detect the presence of people in the room. Key features of the presence sensor include:

• Detection method: Passive infrared method (PIR)
• Coverage angle: approx. 94° × 82°
• Range: approx. 5 m

Brightness sensor

The light sensor measures ambient light with a resolution of 1 lux in the range from 0 to 2,000 lux, with the possibility of measuring and outputting higher values.

• Measurement range: 0 lux... 2,000 lux
• Resolution: 1 lux at 0... 2,000 lux

Logical Functionality

The device includes 4 AND logic gates and 4 OR logic gates, each with 4 inputs. All switching events, as well as 16 logic inputs (in the form of communication objects), can be used as inputs for logic gates. The output of each port can be optionally configured as 1-bit or 2 x 8-bit.

Configuration and Integration

The detector is configured using the KNX ETS software. The device supports up to 254 group addresses and 254 assignments. It has 122 communication objects and operates with a KNX nominal voltage of 30 V DC SELV, with a maximum current consumption of 10 mA.

• KNX medium: TP1-256
• Configuration mode: S-Mode
• Group addresses: max. 254
• Assignments: max. 254
• Communication objects: 122
• KNX nominal voltage: 30 V DC SELV
• KNX power consumption: max. 10 mA

Environmental and Physical Characteristics

The device is designed to operate under a wide range of environmental conditions:

• Ambient temperature: -20... +60°C
• Ambient humidity: 5..95% RH, non-condensing
• Storage temperature: -30... +70°C
• Degree of protection: IP 30
• Weight: approx. 50 g

Installation

The detector is supplied with pre-assembled brackets for installation on a false ceiling and a support ring for installing the connector socket. For installation in the connector socket, a Ø 60 mm socket, 42 mm deep (not supplied) is required.
