You pretty much addressed and answered your own question.....

Now, with the MCC5500, the squawk happens once and shuts off automatically. [See above for a rant on how useless that is]
See my post above in this same thread: "So if you are using this feature on a channel that is actively monitored by a console you probably will have to see if there is a way to disable emergency acknowledge (which there may not be a way to) on the console side." That was on 7/29, a good week ago.

Right because that's how the console works!
So start a new thread in the infrastructure forum titled "Disabling Emergency in a MCC5500" and see what answers you get. I don't think it's possible since the idea is that the console should capture the packet and send an acknowledgment out so the radio stops transmitting the emergency. This then frees up the channel for people who are trying to help the person out of the problem they are in and they are not getting stomped on by an emergency packet.
Maybe you want to consider the use of a "Guard" channel for emergency packets.
The reason why I pointed this out with relation to the FDNY is that they don't use a console on that channel so there is nothing to transmit back a "yes, I heard you now stop alerting packet" That is why this works flawlessly for them.
