Station Features and Operation (DPT/SLT)
• <When KX-TD161 is installed>
Doorphone 1 and Doorphone 2 cannot establish conversations simultaneously. When one
is in use, an extension user cannot have a conversation with the other. This is the same for
Doorphone 3 and Doorphone 4, Doorphone 5 and Doorphone 6, and Doorphone 7 and
Doorphone 8.
<For example>
During a doorphone call between extension A and doorphone 1:
• When calling doorphone 2 from extension B,
— The extension B receives a busy tone.
— The extension B cannot unlock a door by pressing "5".
• When pressing the doorphone 2 button,
— A doorphone call occurs.
— The extension can answer the doorphone call, but cannot have a conversation.
— The extension can unlock a door by pressing "5".
• If you dial "5" again while the door is open, the door will stay open for another five seconds.
• An access tone can be programmed not to be sent to the monitored doorphone before
monitoring starts.
• Doorphone Call Destination
It is necessary to program the extensions that can receive doorphone calls during day and
night mode.
• What if a doorphone call is not answered?
If not answered within 30 seconds, the call stops ringing and is canceled. You can change
from 30 seconds to 15 seconds by System Programming.
• Unlocking the door opener
During a doorphone call, any extension user can unlock the door opener (user-supplied)
from their extensions by dialing "5" to let the visitor in.
• You cannot hold and transfer the doorphone call.
• The door can be unlocked by the following:
1) Extensions that are programmed to receive doorphone calls.
2) Any extension that is engaged in a doorphone call.
• The door opener will open the door, even if a doorphone is not installed.
• You can modify the door opener timer from five seconds (default) to three seconds by
System Programming.
<PT>
• While talking to a doorphone, you can unlock the door using the one-touch dialing
button instead of dialing "5". In this case, "5" must be stored in the one-touch dialing
button by Station or System Programming.
• You can assign a ringer frequency (8 types) to each doorphone by System Programming.
This is only available for DPT.
• With the KX-T7431, KX-T7433, KX-T7436 or KX-T7235, you can call a doorphone
and open a door using the display operation.
