To my understanding the Altronix RB1224 relay will act like a momentary switch.
In my application it could be a way to open or close a garage door.
I have a relay wired to a non-locking key on a 2852 (10 button cuckoo clock phone) that opens and closes one of my garage doors. I also use the contact closure adjunct on my partner acs system to do the same thing, but since it has two sets of contacts I can control both doors. Using some voip bits and some creative engineering, I'm able to dial up my garage doors from anywhere and open and close them. The process is deliberately over-complicated to prevent misuse. I have it on a speed dial on my cell phone with pauses added but its dial a number, get second dial tone, dial another number, wait a few seconds and dial a code.
When it comes to 1A2 and relays.... Your imagination is pretty much the only limit.
Someday I'll dig out my 18 station DICM add-on and use that for relay control for all kinds of things.
