Doorphone Extension (#604 and #605)
Description
Each of these System Programming procedures identifies an extension to which a
doorphone is connected. A doorphone is usually placed near an entrance, to
screen visitors. You can connect up to two doorphones to the system—use
Doorphone 1 Extension (#604) to identify the extension to which the first
doorphone is connected and Doorphone 2 Extension (#605) to identify the
extension to which the second doorphone is connected.
Related Features
■ You must use Doorphone Alert Extensions (#606) to identify the
extensions that are signaled when the doorphone button is pressed. Each
doorphone can signal any number of
alert
extensions.
■ To prevent outside calls from being made or received on the doorphone,
use Line Assignment (#301) to remove all outside lines and/or Pool
Extension Assignment (#314) to remove all pools from the doorphone
extension. (Automatic Line Selection for the doorphone extension will be
automatically
set to select intercom lines first.)
■ You can use Message Light On with the doorphone (for example, the
doorphone’s light flashes as a prearranged signal to a delivery person)
provided the doorphone is connected to a PARTNER ACS processor
module or to an R3.0 206 or later module in a system that is equipped with
a PARTNER ACS processor module.
■ You can wire a Contact Closure on the Contact Closure Adjunct to activate
an electronic lock on the door with the doorphone. Then use Contact
Closure Group (#612) to assign extensions to control the door lock. Use
Contact Closure Operation Type (#613) to specify how long the Contact
Closure remains active when it is activated. Users in the Contact Closure
Group can use the Contact Closure dial code to activate the Contact
Closure, or they can program the dial code on a button on their phones.
Considerations
■ An extension cannot be used for a doorphone and a hotline at the same
time. However, hotlines and doorphones can have the same alert
extensions.
■ You should not assign doorphones to extension 10, 11, or to the first two
extensions of any 206 or 308EC modules.
■ Remove voice messaging system mailboxes from doorphone extensions.
■ You cannot bridge two doorphones together.
