Plug two VRT-1000 Telephones into the DLE-200 Module Unit and what do you have? An Intercom System! That's right, each DLE requires 110VAC power and provides power to each Telephone to function as a Station Intercom. When the Call Button is pushed on a VRT-1000 the other unit will ring.
This is ideal where an Intercom is required in the Machine Room and Elevator. It's easy to upgrade as well.
*Please note that once two VRT-1000 telephones are connected to the DLE-200 unit and are used as an intercom system they do not have the ability to function as an emergency telephone. If you require an intercom system and an emergency telephone you will require three VRT-1000 telephones and one DLE-200 Intercom Module.
