#### Door Interface Unit (DIU)

The DIU is an interface circuit board connected to an ELU-A board via two extension lines (one for voice connection and door bell signalling and one for the door opener function). If the door opener is already wired the second extension line is not needed.

#### Other telephones

Analogue telephones with rotary dial for decadic pulsing or with keys for digit transmission with tone selection (DTMF) can be connected via the ELU-A board.
