Door Box - NEC Univerge SV8100 Features And Specifications Manual

UNIVERGE SV8100
Description
The Door Box is a self-contained Intercom unit typically used to monitor an entrance door. A visitor at the
door can press the Door Box call button (like a door bell). The Door Box then sends chime tones to all
extensions programmed to receive chimes. To answer the chime, the called extension user just lifts the
handset. This lets the extension user talk to the visitor at the Door Box. The Door Box is convenient to
have at a delivery entrance, for example. It is not necessary to have company personnel monitor the
delivery entrance; they answer the Door Box chimes instead. Any number of system extensions can
receive Door Box chime tones.
Each Door Box has a pair of normally open relay contacts that can connect to an electric door strike. Use
these contacts to remotely control the entrance door. After answering the Door Box chimes, a multiline
terminal user can press the Recall key to activate the Door Box contacts. This in turn releases the
electric strike on the entrance door. The device connected to the Door Box contacts cannot exceed the
contact ratings shown in the following table:
The system can have up to eight Door Boxes. Six chime tones are available.
