The Niles DBI-2 doorbell interface lets you hear the doorbell through your Niles MultiZone system. It connects to compatible MultiZone receivers, such as the Niles ZR-4 and the Niles ZR-6. When someone rings your doorbell, it chimes through your system's speakers, temporarily muting your music, so you can hear it wherever you are in your home. No more missing that pizza delivery because you're too busy rocking out!

Customize your system
Choose from the DBI-2's four built-in chimes or record one of your own. You can hook up two separate doorbells with two different chimes — use one tone to alert you when someone wants to drive in the front gate, and another when they're at the front door. The DBI-2 can even be used with your telephone paging system to provide home-wide alerts.
