The Motion Sensor module from Telecom Behnke is a compact device designed for installation in intercom systems, intended for detecting movements within a defined area. It is made of aluminium, ensuring a robust and durable construction. The module is designed for use in low-voltage systems and serves as a sensor component that can be integrated into existing systems to enable, for example, the activation of doorbell tones, lighting, or video surveillance upon motion detection.

Motion Sensor
The sensor detects movements within a defined environment and responds with an output signal. The range is configurable and can be set between 0.2 and 10 metres, allowing the device to be flexibly adapted to different application scenarios. Detection is performed via an infrared sensor that detects movements in the near field. The range depends on the environment, such as the temperature difference between the object and surroundings, as well as the surface reflectivity.

Field of View
The sensor's field of view is adjustable horizontally between 80° and 120° and vertically between 40° and 110°. The exact coverage depends on the distance to the object, with the angle tending to be smaller at greater distances. This allows for targeted coverage of areas, such as entrance zones, corridors, or stairwells, without unnecessary overlaps or blind spots.

Technology Explained Simply
The module operates using a passive infrared sensor (PIR), which detects heat emissions from moving objects. The sensor technology is designed to respond only to movements, not to static heat sources. The configurability of range and field of view is achieved through internal settings adjusted during installation. Detection occurs without additional power supply from the network, as the module is designed for integration into existing intercom systems.

Compatibility and Accessories
The module is specifically designed for use in intercom systems and can be integrated into existing setups. It features a potential-free relay that serves as the output signal and can be used, for example, to control relays, switches, or other electrical loads. Compatibility with other components of the intercom system is ensured, provided electrical and mechanical requirements are met.

Mounting and Installation
Mounting is performed at a suitable location that covers the desired detection area. The module is designed for wall or ceiling mounting. Installation requires connection to a power supply and possibly to a control unit or intercom system.

Operational Advantages
The module provides flexible and reliable motion detection that can be adapted to specific requirements. The configurable range and adjustable field of view enable precise coverage of the desired area. The potential-free relay offers a universal interface for controlling additional components. The aluminium housing construction ensures high mechanical stability and resistance to external influences.
