Can I add secondary keypads to the DSC Impassa?
You can add additional keypads to the DSC Impassa. They will have to be wireless keypads though. You cannot use any of the wired keypads DSC makles for this system.
The keypads that can be used with this system are the WT5500 and WT5500P. We always recommend adding additional keypads to a system such as the Impassa that are all-in-one wireless systems. You never want to put the main unit by an entry door.
