The door intercom station of the Series 20 by Telecom Behnke, type 20-0016-BS, is an electronic local unit for decentralized applications in buildings and industrial premises. It serves as a door station within intercommunication systems, particularly in office buildings, at cabinet installations, doors, and gates. The device is modular in design and allows integration into existing systems. The housing is made of aluminium and finished in silver, offering a robust and aesthetically suitable design for indoor and outdoor use.

Applications

The door station is designed for use in office and administrative buildings, industrial facilities, as well as at gates and cabinet installations. It is particularly suitable where decentralized communication via a door or access control is required. The modular design enables flexible adaptation to different requirements, such as integration into existing door intercom or access control systems.

Functions and Equipment in Detail

The unit is designed as a local electronics (SIP / a/b) and allows connection of up to 8 call buttons, 1 keypad block, 1 speaker, and 1 microphone. This enables centralized control of multiple access points from a single location. The unit features an RJ45 socket (out) for network connection, as well as a USB port for data transfer or firmware updates. Additionally, it includes 2 switching relays and 1 alarm input, enabling connection to external security or alarm systems.

Technology Explained Simply

Power supply is via PoE (Power over Ethernet) according to the 802.3af standard, enabling power and data transmission over a single network cable. This reduces the need for separate power lines and simplifies installation. The unit is locally deployed, meaning it is not directly connected to a central control unit but operates independently, yet communicates over the network. The housing size 2 defines the physical form factor and the number of controllable modules, with the maximum number of call buttons (8) and integrated functions (relays, alarm input) determining the unit’s capacity.

Compatibility and Accessories

The door station is designed for use in modular systems and can be combined with other components of Series 20. The use of SIP protocols (SIP / a/b) enables integration into IP-based communication systems. The RJ45 socket (out) allows connection to other devices or a central control unit. The integrated switching relays and alarm input enable connection to external switching and alarm systems, with exact compatibility depending on the respective systems.

Mounting and Installation

Installation is carried out at the desired door or access point. The modular design allows flexible mounting, with the exact mounting method depending on the specific application and installation location. The RJ45 socket (out) enables network connection, with cabling to be performed according to applicable standards.

Advantages in Operation

The door station provides a robust and reliable communication solution for decentralized access points. PoE technology reduces installation complexity, while the modular design enables flexible expansion. The integrated switching relays and alarm input extend functionality and allow integration into existing security and access control systems. The use of SIP protocols ensures compatibility with modern IP-based communication systems.
