Product description

The identification card reader for BEHNKE modules can be installed directly in SIEDLE speaker systems. The reader requires one module position. Therefore it is ideally suited for use in outdoor installations.

The reader has a display with three LED arrays and a Piezo buzzer.

The SCALA reader in BEHNKE design can be easily integrated in existing BEHNKE intercom systems.

The data of the transponder is converted 1:1 analogue/digital and sent to the SCALA controller. The security of the encryption is identical to the security of the air interface between the user identification card and reader.

All safety-relevant processes do not take place in the reader, but are controlled in the controller. This rules out tampering between the identification card, reader and controller based on the current state-of-the-art technology – such as tapping the encryption or replacing the reader with a compromised unit.

The SCALA reader has integrated temperature and voltage sensors as standard, which permanently measure the temperature and input voltage of the reader. This can help to prevent faults.

The available operating states are displayed via a yellow, a dual colour (red/green) and a RGB-LED. The transmission quality between the user identification card and the reader is displayed via the RS485 bus with a communication LED.

The communication between SCALA reader and controller takes place via a RS485 interface. Both the communication and the voltage supply takes place via the 4-wire cable.

The wiring of the reader takes place intuitively and is particularly easy.

The reader is mounted in the BEHNKE element in the usual way during installation.
