Door Box
Description
The Door Box (P/N 922450) is a self-contained analog 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 or ringing to all extensions programmed to receive chimes. To answer the chime or ringing, 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 instead.
Door Box Relays
Any keyset extension that receives Door Box chimes or ringing can control a control relay, which in turn
typically enables an electric strike on an entrance door next to the Door Box.
Door Box Alerts
The system uses Ring Groups to control Door Box alerts. When a visitor at the door presses the Door Box
call button, the Door Box will alert (chime or ring) all the extensions in the Ring Group to which the Door
Box belongs. For example, if Door Box 309 and extensions 301 and 302 are in Ring Group 1, pressing the
call button alerts 301 and 302.
Operation
Use a Door Box to remotely monitor an entrance door.
