Hi folks,

Just wondering if anyone has set up 1 door phone with multiple door opening controllers on it(working on a MICS). From what I have read in the door phone manual, up to 12 DOC's can be installed with 1 door phone. I have a customer who is looking at having possibly up to 6 DOC's working off of 1 door phone which some would be opening automatic gates to allow vehicles thru(same as opening a garage door). Is the setting for which digit is dialed on a Nortel phone to operate a particular DOC set within the DOC itself? I have read that the maximum voltage for a DOC's dry contact is 24Volts. Does anyone know what the maximum current is?
Any help would be greatly appreciated.
Thanks! Tim
