Call buttons:
- Pressing the call button at the Entrance or at the SOS Point should generate a call in private ringing mode to the Control Room.
Relay control:
- A relay output to the CCTV system should be activated when the private ringing starts. There is one relay for each substation. Use the outputs 5 and 6.
- The relay should stay activate until the call is accepted and the conversation is cancelled. (If the call is not answered, the relay must drop when the ringing times out).
