12Extended code lock functionYou can only use the extended code lock function for the first code (memory location). The function can beset with the configuration software configoTM.You can connect a time switch (alternatively: motion detector, brightness sensor, door contact of a lock etc.) to thebipolar pluggable screw terminal (contacts 1 and 2, seeDevice overview). The switching input at the terminals 1 and2 can be configured (opening/closing contact) and influences the effectiveness of the code on the first memory loca-tion.The additional device effects the code entry.Example: In combination with a time switch access is only granted / not granted in the determined period of time,depending on the configuration.The programmed action is executed, if the code is entered correctly and the contact, according to the configurationof the switching input, is effective.Initial operationWARNING! Danger to life due to electric shockObserve the safety regulations according to DIN VDE 0100, when working on main power connections of230 V.► Install the devices of the system voltage-free and completely.► Do not connect the video wires V1 and V2 with the P-, a- or b-wire. Observe the polarity when connecting the vid-eo wires V1 (+) and V2 (−).► Proof the a-, b- and P-wire against each other on short-circuit.► Switch on the mains voltage.Connect the floor push-button► Connect the floor push-button to the terminals E and P.Alternatively you can connect the floor push-button to the terminals a and E.Ensure that the a-wire of the power supply and control unit is connected to the a-terminal of the indoorstation.Setting the volume of microphone and loudspeakerCAUTION! Device damage.Use the enclosed small screw driver to adjust the volume!
