Automatic Door Locks Type?

["Shiraz J. Cupala" <shirazc@xxxx>]

Hello everyone! I'm trying to figure out how to wire my alarm system 
to automatically open the door locks. Has anyone done this? Would you 
give me some pointers? I think the lock type is reversing polarity 
but I'm not sure. Is there a relay I can wire into? In the shop 
manual there is a relay labeled Door Lock something but I'm not sure 
if that's it.

thanks!
