Works exactly like a NX-148E keypad, nothing more, nothing less. We usually use a couple of 148E keypads in the systems in less prominent areas like garage entry etc, so easy transision for the customer. Really fast as well, pretty much like the regular alarm keypad. We trigger events from the different wave file signals/alarm events in the module, because it doesn't give you direct control/feedback over zones. Easier to setup and faster responsenthen the serial module, but a more basic way of doing it.
