Door Box
Description
The Door Box is a self-contained Intercom unit typically used to monitor an entrance door. A visi-
tor 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 just answer the Door Box chimes instead. Any num-
ber 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 keyset user can press FLASH to activate the Door Box contacts. This in turn releases the
electric strike on the entrance door.
The system can have up to eight Door Boxes.
Dual Line Appearance
Description
Each keyset has two line appearance keys (CALL1 and CALL2) for placing and answering calls.
These line appearance keys, assigned to the extension’s number, simplify operations for busy users.
For example, the user can easily process a new call on one appearance with a call in progress on the
other.
