Digital Door Phone Unit DK-DPU
The DK-DPU is a digital doorphone unit. It is housed in an aluminum silver gray case which provides a rugged construction base. The internal components are protected against moisture by gaskets and seals within the housing.

The digital doorphone unit is connected to the telephone system via a standard digital station port, uniquely allowing for a large quantity of doorphones to be installed.

The digital doorphone can be programmed to ring a specific station or a group of stations when the call button is pressed. It also can be called by another station within the system. A relay inside the door phone unit can be activated by an internal user to activate a door lock mechanism for entry into a door.
