I apologize....I'm pretty new to this but having fun so far. I'm having trouble connecting my smoke alarm relay to my 120 volt system. The diagram is confusing. I believe red goes to red, white to white....but does black go to the black line in and then blue to the black lead of the  smoke alarm?...or should all three blacks be wired together? Then as far as hooking into connected, is it yellow to a konnected zone and blue to konnected gnd? Here is a link to the wiring diagram 1201-7208-01 (shareddocs.com)

Thanks for your help

  • Relay Module Power Supply Konnected 
    Black  AC Hot Black  
    White  AC Neutral  White  
    Red   Interconnect Signal Copper Ground  
    Blue   Common Contact    Zone 12
    Yellow   Normally Closed Contact --- ---
    Orange Normally Open Contact   Zone 12
    Gray  9-Volt DC Output  --- ---
  • i understand the wiring but I do not understand the action.  In this confiuration the switch is normally open.  if I understand correctly, when a sensor within the system detects smoke and an interconnect sisgnal is sent to energize all alarms, the relay switch closes.  What voltage is output?  In the diagram for the SM120X everywhere the orange (normally open) wire is noted is says this wire supplies 120 volts.  if true, wouldn't that fry the Konnected board?
