- No power supply - Power supply is connected incorrectly (poles reversed)
Door opener is not activated
- Check the door opener connection -> Use the closer - No power supply for door opener -> on site (not in parallel with Behnke power supply) - Call station sends no DTMF tones -> See: Door call station cannot be configured - Code for opening the door is not or is incorrectly configured (as delivered condition 0#)
Door call station has no function
- Check or measure a/b port - If additional supply is connected, check whether it is floating - Several door call stations connected in parallel -> Each phone requires its own analog connection and its own floating power supply - Loop current of the phone system / PABX -> must be larger than 20 mA See: Technical data of the door call station
