Is this doable?

I want to be able to control a door strike via the ELK-m1 as well as through my home SIP phone system.

So for the ELK, I want to use a keypad to the m1-kam.

And for the SIP door, I want to use the Cyberdata SIP doorphone : http://www.cyberdata.net/products/voip/digitalanalog/intercom/docs.html


What is the best way for me to do this? I would want to be each running idependately, so if the SIP phone system is down, the elk can still open and vise versa.


THank you
 
I am not following the "Keypad to the M1-KAM" comment but..

Your SIP phone has a relay output. I would use the dry contact of the phone and use a Form C relay on the Elk in parallel to supply power from a "door strike" power supply to the strike if the strike is fail secure.

If the strike if fail safe and you need other relay(s) to accomplish this as I just read the instructions on the phone and it only has a normally open set of contacts.
