Connection
Step 1: Connect door opener to relay 1, if required.
Relay = voltage-free contact = only operates the door opener, without supplying it with electric energy;
the door opener requires its own power supply! Relay 2 is available for further switching functions (see
comprehensive technical manual; avalailable as PDF on the Internet).
S
tep 2: Connect 12 V DC, if required (potential-free – use Behnke plug-in power supply 20-9500).
Only required for: illumination, camera, integrated heating, integrated add-on amplifier;
not required for: telephone operation, including all functions.
S
tep 3: Connect telephone line (a/b line from analogue PBX extension or analogue direct exchange line) => a long
beep signals the telephone’s operational readiness.
