I just acquired an ADT Impassa system, and I am wanting to know all this panel is capable of, particularly if it can drive a security siren, but any other info is helpful.
Because the Impassa system is wireless, you will need a wireless siren.

Could i somehow make it wired or make the siren into a control for wired devices?
not surr if possible, but dsc makes wireless input modules so you can use wired sensors but i am not sure if they make a wireless output module
