The Aiphone DB series intercom systems are a cost effective solution where an intercom system is required for communication. The front door station (DB-1DS) only requires 2 wires, which allows communication as well as door release.
The indoor handsfree (DB-1MD) master station allows communication with the front door station. If you require multiple answering points the (DB-1SD) sub-master is available.
Vandal resistant codepads allow easy access control where required.
