Connection
To power the unit for voice, connect the telephone wires into the terminal (on the right side).  Using either a standard analogue phone line or an analogue extension on a PBX.
For the external power supply, connect to the terminal "12V" external power supply AC min. 10V / max.  15V or DC min. 12V / max. 18V.
The energy consumption of a connected electrical (magnetic) lock (0,5A – 1,0A) determines the load on the power supply. If you activate the heating feature the PCB current will climb  to about 150mA. We recommend power supply AC 12V/1A.
All mounting, control and setting elements are located under the speaker front aluminium grille.
