Door Phone/Door Lock with DDCB Interface

Calling from a Door Phone

Each door phone has a push button that rings selected telephones with one of three unique bing- bong sounds. The door phone’s location displays on ringing telephone LCDs. The three bing-bong ring types are permanently assigned to each of the DDCB ports (A, B and C) as shown in Figure 12-16. Door phones can also be programmed to ring over the system’s external paging equipment. When a telephone answers a door phone call, a two-way talk-path is established between the calling door phone and the called telephone.

Calling a Door Phone

Each door phone has a unique number (#15XX, where “XX” = 01~24 max., depending on system size) that can be dialed from system telephones. When a system telephone calls a door phone, the door phone does not ring but provides a two-way talk-path between the calling telephone and the called door phone. This enables telephone users to monitor sounds in the general area where the door phone is installed.

Door Lock Control

As an option, Port B of the DDCB can be connected to a door lock control device, instead of a door phone, to unlock a door. The door lock control device is not supplied by Toshiba and must be ordered separately. The door lock option is a hardware jumper located on the DDCB. This option provides relay contacts that will open, or close the Port B wire pair when a telephone’s door lock button is pressed or when a door lock feature code is dialed from a telephone (see Figure 12-16for option settings).

Door Phone/Lock Programming

Door phone assignments are in Program 507 and door lock assignments are in Program 508.
