Section 3: Features DS1000/2000 Product Description
Door Box
Availability: Requires DS2000 U Slot (02.nn.nn) or DS1000.
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 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.
There are two types of Door Boxes: Analog Door Box P/N 92245
and Digital Door Box P/N 80560. Both Door Boxes operate identi-
cally. There are, however, some differences:
●
The Digital Door Box connects to a digital station port. The
number of Digital Door Boxes you can install may be limited
by the System Load Factor. See DS2000 System Load Factor
Calculations on page 19 and DS1000 System Load Factor Cal-
culations on page 23 for more.
●
The Digital Door Box is available in U Slot (02.nn.nn) versions of DS2000 and all versions of
DS1000.
●
The Analog Door Box is only available in DS1000 (2 maximum). An Analog Door Box plugs
into one of the dedicated Door Box ports (DOOR1 or DOOR2).
●
The Analog Door Box can be mounted outside. The Digital Door Box is not intended for out-
door installations. Turn to Specifications on page 101 for more on the Analog and Digital
Door Box specifications.
Any extension that receives Door Box alerts can also activate a control relay. If the relay is con-
nected to electric door strike circuits, an extension user can press FLASH or a soft key to remotely
lock and unlock the entrance door. There is a single relay in DS2000, located on the CPRU. There
are two relays in DS1000, one for each Analog Door Box. Digital Door Boxes in DS1000 do not
provide relay control.
The system uses Ring Groups to control Door Box chimes. When a visitor at the door presses the
Door Box call button, the Door Box will alert (chime) all the extensions in the Ring Group to which
the Door Box belongs. For example, if the Door Box and extensions 301 and 302 are in Ring Group
1, pressing the call button alerts 301 and 302.
Door Box Call Coverage
If a Door Box uses Door Chime type 0 (normal ring), you can set up Call Coverage keys for the
Door Box Ring Group. This allows extensions that are not members of the Ring Group to answer
Door Box calls. Extensions with Call Coverage keys to the Door Box Ring Group can also activate
the relay.
