The Steinel IS 345-E KNX AP V3 is an infrared motion detector designed for use in both indoor and outdoor environments. It is particularly suitable for corridors, passages, and functional rooms where reliable motion detection is required. The device is available in a surface-mounted version and offers a mounting height of up to 5 metres. The detection areas are defined radially as 12 x 6 metres and tangentially as 23 x 6 metres, enabling comprehensive coverage of large spaces. The motion detector features a large connection compartment, simplifying installation and wiring.

Applications

The IS 345-E KNX AP V3 is suitable for use in buildings with high requirements for security technology and automation. It is commonly used in office buildings, apartments, hotels, or industrial facilities where automatic lighting control or alarm systems based on motion detection are necessary. The mounting height of up to 5 metres makes it particularly suitable for high ceilings or large rooms. The combination of indoor and outdoor use expands the range of applications, for example in entrance areas, stairwells, or covered outdoor spaces.

Functions and Equipment in Detail

The motion detector operates on the principle of infrared technology, detecting movements in both visible and invisible ranges. Detection occurs via a radially oriented field of 12 x 6 metres and a tangentially oriented field of 23 x 6 metres, achieving broad coverage. The surface-mounted design enables quick and easy installation on ceilings or walls. The large connection compartment simplifies wiring and integration into existing electrical installations.

Technology Explained Simply

Infrared technology detects temperature changes caused by moving objects, particularly people. The sensor responds to heat radiation and detects movements within the defined detection areas. KNX integration enables communication with other devices in the building automation system, allowing the motion detector to be used, for example, for controlling lighting, blinds, or alarm systems. The surface-mounted design (AP) means the device is mounted directly on the surface without requiring a wall or ceiling cutout.

Compatibility and Accessories

The IS 345-E KNX AP V3 is part of the Steinel product range for security technology and is designed for use in KNX systems. It can be integrated into a networked system with other KNX-compatible devices, such as switching actuators, dimmers, or sensors.

Mounting and Installation

Mounting is carried out on the ceiling or wall at a height of up to 5 metres. The surface-mounted design allows direct fixation to the surface, with the large connection compartment facilitating wiring. Installation requires an electrical connection integrated into the existing network.

Advantages in Operation

The motion detector offers high detection reliability through infrared technology and a wide detection range suitable for large rooms. KNX integration enables flexible use in networked systems. The surface-mounted design reduces installation time and simplifies the process. The ability to operate in both indoor and outdoor environments expands application possibilities without requiring additional devices or adapters.
