Is there any indication to the central station (while working with installer) to verify that contacts have been activated properly?
Yes. Once you have connected the unit, in the lower portion of the screen, you will see red LEDs representing each alarm input. If there is a contact occurring with the input, the LED will appear red on the outside with white in the middle. This should only be occurring for a few seconds, as the inputs should be programmed for a momentary contact.
