• A relay output to the CCTV system should be activated when the private ringing starts. There is one relay for each substation, RCO 5 and RCO 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).
