Ah.
The 6400 has a "walk test" option on the panel which makes it bleep and display the sensors as they trigger. In a large house, you can take the panel off the wall and carry it around with you as you learn-in the sensors, the panel will run on the standby battery for about 8 hours. I find it helpful to pencil the device numbers on the cases of the sensors or a post-it during learning-in to make it quicker to check which ones have reported.
The 6000 range sensors also have a little black test button to make them send a signal; this verifies that they are being received by the panel, but you still need to walk test to make sure it can see you, and you need to walk-test with the panel in its final position just in case there should be an obstruction like a metal or electronic item interfering with the signal path. .
