Connecting a Door Bell Button
Warning: Power surges, which can occur during electrical storms, can cause life-threatening electric shocks or damage or destroy the PBX.
• Do not open an already connected PBX during an electrical storm. Also avoid disconnecting and connecting electrical lines during an electrical storm.
Requirements:
• Installation cable (e. g. J-Y(St)Y 2x2x0.6) with the following characteristics:
-At least five wires (for four door bell buttons)
-Unscreened; however: screened for unfavourable conditions, for example, near a strong transmitter or an electrical power line
1.Lay the line.
2.Connect the But1/Klin1 terminal to the contact of the first door bell button (e. g. labelled 1). 3.Connect the But2/Klin2 terminal to the contact of the second door bell button (e. g. labelled 2). 4.Connect the But3/Klin3 terminal to the contact of the third door bell button (e. g. labelled 3). 5.Connect the But4/Klin4 terminal to the contact of the forth door bell button (e. g. labelled 4). 6.Connect the +12Volt terminal to the joint contact of the door bell buttons (e. g. labelled ).
Further steps:
• To finish commissioning, you need to configure the COMmander 2TMS (R) module in the Configuration Manager and set up the corresponding door terminal.
