Hello Everyone,
Customer has 2 doors w/strikes on each. He wants door phones at each location with connectivity to the strikes.
Would the customer need 2 DOC to independantly wire each strike seperatley? If we wire both front door and back door strikes to one common DOC then both front and back door strikes will open at the same time when released, is this correct? I just wanted to be sure of the solution before adding the additional DOC.
Best Regards,

Yes you a correct a DOC has only one NC or NO dry contact and can only control one door, or for that matter any group of doors wired in parallel. However you would need a separate DOC for each door that you would like to control individually.
