Solution
CCTV Control: * Pressing the call button at the Entrance or in the Elevator should generate a call in private ringing mode to the Main Guard.
- A relay output to the CCTV system should be activated when the private ringing starts. There is one relay for each substation.
- 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).
