The Business Series Terminal (BST) Doorphone is used as an intercom
to control access to your building. Pressing the Call button on the BST
Doorphone calls one or more telephones, and/or sends a dist inctive
chime to telephones in an assigned page zone.

Placing an internal call from any telephone on the system to the BST
Doorphone sets up a two-way voice call.

Additionally, a Door Opening Controller can be installed to permit the
activ ation of loc ks on doors or gat es. Contact y our sys tem administr ator
for more information.
