Door Box
The Door Box is an intercom unit that can be installed at an entrance to a building. The unit
houses a Call Button that a visitor can use for two-way communication with a person inside
the building who has a keyset with a call coverage flexible button associated with the Call
Box.
Alternatively, the unit can be mounted beyond the reach of visitors and wired to a
conventional doorbell switch, which then serves as the Call Button. This option helps protect
the Door Box from damage that might be caused by rough handling by visitors or vandals.
The unit is wired into a DTIB port in the KSU.
