Connecting the Door Intercom System
What is the Door Intercom System?
What does the Door Intercom system do?
Lync Controller
The Door Intercom system consists of two primary components - the Door Interface hub (model DI-21) and
a Door Station (model DOOR1). The DI-21 can interface with one common phone line via standard RJ-11
connectors and up to two Door Stations via standard Cat5 or Cat6 cable using standard RJ-45 connec-
tors.
The DI-21 requires a 12V power supply (included) and connects via your own Cat5/6 cable to Lync Con-
trollers that include a “Door Interface” RJ-45 female connector. Please note that early versions of the
Lync controller do not include this connection port and some versions that do include this port will
require a rmware upgrade before the DI-21 will work properly. If you purchased your Lync controller
prior to August 1, 2012, please contact HTD to determine what steps are necessary to make your system
compatible with the Door Interface system.
Once connected, the Door Intercom system allows you to communicate independently with up to two Door
Stations. These Door Stations are identied as Front Door and Back Door on your LyncPad keypads. A
conversation can be initiated from inside the home in the same way a point-to-point intercom conversation
is initiated, i.e. you simply press the left or right arrow Zone Select buttons to select the zone you wish to
call and then press the TALK button. While the TALK button is depressed, your voice will be heard through
the Door Station you selected. But unlike a typical point-to-point call which requires a person in the other
zone to press their TALK button to talk back, with the Door Stations, when you release the TALK button, you
will automatically hear the voice at the door. In other words, the person at the door has no way to initiate
the conversation inside the house - you choose when to hear them. To end the two-way conversation,
simply press one of the Zone Select buttons.
The Door Station also includes a doorbell button which will trigger the FRONTDOOR.MP3 le (or BACK-
DOOR.MP3 le depending into which port the Door Station is connected) to play inside the house. This

Using Your Own MP3 Files
The Door Intercom system is congured to play three separate les stored on an SD card (included) in-
serted into the back of the DI-21: FRONTDOOR.MP3, BACKDOOR.MP3, and PHONE.MP3. Your system
includes three sample les, as well as several alternate sound les, already loaded on the SD card.
In order to change which le you hear, you simply need to change the name of the preferred le to either
FRONTDOOR.MP3, BACKDOOR.MP3, or PHONE.MP3. Remove the SD card from the DI-21 and insert
it into your computer in order to play the existing sound les and/or add your own sound les.
Replacing the sample les with your own recorded les or favorite songs is highly encouraged! Feel free
to add music les that cleverly relate to answering a door or phone, or are relevant to the current season
or holiday, or that are simply more personal to you. Have fun with it!
Some tips when using your own MP3 les:
A doorbell le should typically be at least 30 seconds long. Once the doorbell le times out, the TALK but-
ton on each LyncPad will automatically return to its previous setting. If the le is too short and times out
before you can get to a LyncPad, you will have to manually select the appropriate Door Station to initiate
the conversation. On the other hand, if the le is long and you are able to press the TALK button before the
le reaches its end, you are automatically connected to the initiating Door Station.
The PHONE.MP3 le will NOT start over with each consecutive burst of “ring” voltage unless the le is very
short. Again, we recommend a le that is about 30 seconds long. However, if you prefer a short sound le
to match the length of the ring voltage, you will likely want to pad the le with a few seconds of no sound.
In doing so, you may be able to achieve a sound le length that starts over with each new ring voltage. If
the le is too short, it is possible for the system to alternate between short bursts of the sound le and the
source you were already listening to. The effect is not pleasant!
MP3 le will ONLY play into zones which are currently powered on, not in MUTE, and not in DND (Do Not
Disturb) mode. If you are using the Door Intercom system as your primary method of hearing the doorbell,
we recommend that you keep the LyncPad in your primary zone always powered on. You might even con-
sider naming a source input that is not being used as “Standby” or something similar. Rather than powering
off this zone you would simply select the Standby source when not in use.
When a doorbell button is pressed, the appropriate sound le will play until the sound le ends or until the
door is answered at a LyncPad. The door is answered by the rst zone in which the LyncPad’s TALK but-
ton has been pressed. Once this occurs, all other zones return to their previous state. The communication
with the door station is only between the answering zone and the door.
The PHONE connection is used to play the PHONE.MP3 le when a phone line “ring” voltage is sensed by
the DI-21. All zones currently powered on and not muted and not in DND mode will hear the PHONE.MP3
le. The PHONE.MP3 le will play until the “ring” voltage is no longer sensed; that is, until the caller hangs
up their phone prior to being answered or someone in the house answers the phone. “Ring” voltages are
typically sent 4-6 seconds apart and vary by location, so it is possible for the phone connection to be dis-
connected or the phone answered and the MP3 le will continue to play for several seconds.
The PHONE connection is NOT used to answer or otherwise communicate with the incoming call. It is
simply a means to let those within range of the whole-house audio system know there is an incoming call.
Note: The volume level for the MP3 les is set using the Volume Control knob on the back of the DI-21.
Similar to intercom volume, the volume of the MP3 les is NOT dependent on the volume level set for each
zone.

Phone-to-ZoneTM
Phone-to-ZoneTM Connection
Phone-to-ZoneTM is a unique feature developed for the Lync 6 and Lync 12 controllers (specically V3 con-
trollers - V2 and V1 Lync controllers do not support the Phone-to-ZoneTM feature). Phone-to-ZoneTM allows
you to use your phone or smart device to “intercom” with any zone in your home! Calls are initiated from
the phone and achieve two-way communication with any LyncPad. If a zone does not have a LyncPad
installed, you can still initiate a one-way call (page) into the zone.
The DI-21 is one of the essential pieces of hardware that makes Phone-to-ZoneTM possible with the Lync
System. The other essential piece of hardware is a pc or smart device with SkypeTM installed.
The diagram below shows you how to connect the DI-21 in order to use the Phone-to-ZoneTM feature. More
information on how to use Phone-to-ZoneTM can be found within your Lync System owner’s manual.
