Thanks UKHeliBob!
I will look into that commend when I get home. I left the relays like this so they are off, not using power. I didn't want them going off if power is lost to them, though, I may switch the siren one around so it does do that.
I found a home for this too, garage door. Not the overhead one the man door on the side. I found a nice solenoid I can stick in the jam that will push the bolt out and allow the door to open.
