The motion sensor with integrated speaker from Telecom Behnke is a module for low-voltage systems, designed in size 2. It is used for detecting movements in indoor and outdoor areas and simultaneously enables acoustic signal transmission via the built-in speaker. The device is made of aluminium and features a V2A design, providing a robust and aesthetically pleasing surface. The installation solution is designed for integration into intercom systems or security systems, with functions adjustable via configuration.

Motion sensor
The sensor detects movements in the vicinity of the device and responds by triggering a relay. The range is configurable and can be set between 0 and 10 metres, with the actual range depending on the environment and installation conditions. The opening angle is at least 70° horizontally and at least 45° vertically, with these values potentially varying depending on the set range. The sensor technology enables precise detection of movements within the defined area.

Functions and equipment in detail
The module features an integrated speaker, which can be used for acoustic signal transmission. This enables use in intercom systems where voice transmission or an acoustic signal is required. Additionally, a configurable relay is integrated, which can be operated as a normally open or normally closed contact. The relay is potential-free, allowing flexible use in various circuits. Configuration is performed via the device's designated adjustment options.

Technology explained simply
The integrated speaker function allows playback of tones or voice messages transmitted via the system. The relay acts as an electrical switch, triggered by motion detection, thereby enabling connection to other components such as alarm systems or door openers. The potential-free design of the relay allows universal use without specific voltage requirements.

Compatibility and accessories
The module is designed for use in intercom systems and low-voltage systems. It can be integrated into existing installations, with compatibility with other components depending on the specific system architecture. Use in combination with other modules or devices from the same product line is possible, provided interfaces and operating conditions are compatible.

Mounting and installation
Mounting is typically done on a wall or ceiling, with positioning chosen to optimally utilise the opening angle. Range and relay configuration are performed on-site, with exact adjustment options not specified. Mounting is intended for professionals in the electrical and IT sectors.

Advantages in operation
Using this module enables combined motion detection and acoustic signal transmission, which is advantageous in security and communication systems. The configurable range and opening angle allow application-specific adaptation. The potential-free relay offers flexibility when integrating into existing circuits. The robust aluminium construction with V2A design ensures long service life and an attractive appearance.
