5. CONNECTIONS
1. Telephone Ringer Selector Switch – This switch enables/disables ringing of the telephones. When positioned
to the left, this switch enables ringing of the telephones.
2. Doorbell/Door Strike/Sound system mute (Relay Contacts) Connecting Jack – The center two pins connect to
the doorbell button and will ring an existing or new doorbell. The adjacent pair will provide a six second
closure upon door button depression or incoming telephone line ringing (this is used to mute a sound sys-
tem). The adjacent pair offers a user selectable (*8) relay closure than can be used to operate a door strike or
other relay controlled ancillary devices.
3. Door Speaker Connecting Jacks – Each of these jacks enables a connection to door speaker for communicat-
ing to a door speaker.
4. Telephone Line (In & Out) Connecting Jack – This jack provides connection to the incoming telephone line
on the inner pair and connection to household telephone(s) on the outer pair.
5. Power Status LED – When "ON," this lamp indicates the presence of power to the unit, when "OFF," it indi-
cates the absence of power to the unit.
6. Power Supply Jack – This jack is the connecting point for AC power supply to the unit; The supply is typically
16 Vac at a minimum of 250 mA, but can be as high as 20Vac, which will provide greater ringing power to
the telephones. Can also use a 16-24 VDC supply. (Note: Do not exceed 24 VDC or serious damage can
occur to the controller unit)
CAUTION: For added protection we strongly recommend you use surge protectors on both your power sup-
ply and on the C/O line (phone line) to protect against lightning and other energy surges.
6. INSTALLATION
To complete the installation the installer must supply the following:
• RJ31X/CA38A disconnect and bypass jack. This will provide a bypass capability whereby the telephone line
continues to work if the DTI-1 needs to be removed from the telephone line. Note: If installation is done at a
location that has an existing alarm jack (RJ31X/CA38A) then ensure that the alarm is installed before the DTI-
1 RJ31X/CA38A jack. Otherwise, the alarm system may not have disconnect priority.
• Two plastic wall anchors to mount the TDB-1 door speaker unit near a point of entry.
Figure 1 shows the detail of the connectors located on the front of the unit. Figure 2 shows interconnection of the
DTI-1 with other parts that form the system.
Installation of the system requires that the installer install a 4-conductor wire (24 AWG) be installed from the
location of the door speaker unit to the location of the system control unit. It is recommended that the system
control unit be installed near the point-of-entry of the customer's main telephone line. Please ensure that ade-
quate AC power is available in the general vicinity.
1. First install the Back Mounting Plate. We recommend that you use a silicon sealer to protect the wiring. Apply
a ring of silicon around the round hole on the rear of the mounting plate as shown in figure 3.
2. Thread 4 conductor wire through the hole in the Back Mounting Plate.
3. Use the included 1/2” dry wall screws to mount the back plate to the wall. Make sure the the silicon makes a
seal between the wall and the plate. Drive screws through the oblong screw holes and into the wall as
shown in figure 4 but do not tighten screws down all the way. Once all screws are driven, adjust plate to
make sure it is level. Once the plate is level, tighten the screws.
4. Connect the four wires to the wiring posts on the rear of the TDB-1 as shown in figure 5.

5. Attach front of TDB-1 to Back Mounting Plate (already anchored on the wall) by screwing in the two white
oval-head machine screws (included) as shown in figure 6.
NOTE: The DTI will support an optional second door station. In this configuration both stations are active
when using the DTI. In some cases high ambient noise may cause one speaker to drown out the second. This
can be corrected by repositioning the affected speaker or by installing a second control unit in series providing
independent control of the speakers.

4. While on a regular telephone conversation, depression of the door speaker button will cause a unique call
indication tone to be applied over the conversation. The door bell will also ring, if enabled. *4can be
used to put the telephone call on hold and connect to the door speaker. Using *4again will return to the
telephone call. This hold feature can be used only once per door speaker button depression. Alternatively, a
user can hang up the active conversation and then pick up the receiver and a connection will occur with the
door speaker. A user has two minutes to do this, otherwise, *#*needs to be used. If a door strike sys-
tem has been installed, to automatically open a door or a gate, a user can activate it by depressing *8on
the keypad while connected to the speaker. This will cause a five second contact closure and open the door
or gate automatically.
8. PROGRAMMING
NOTE: If the power goes out, the DTI-1 will lose its
programming and return to factory setting, including password.
To prevent loss of programming, use of a UPS power device
is recommended.
7. OPERATION
1. If your doorbell rings or you hear the unique DTI-1 ring signal, pick up any telephone in the house within
two minutes. You can now talk to the person at the entrance.
2. If two minutes has expired, then pick up any telephone and press *#*on the touch tone keypad on
your telephone. This will connect you to the door speaker.
NOTE: Using *#*can be done at times when no one has depressed the door speaker button and pro-
vides the user with a monitor function.
3. The DTI-1 provides a six second contact closure when the door button is depressed or when the telephone
line rings. This provides a mute function if connected to Russound Multi-Zone controller such as the
CA4.4pi, PR-4Z and CP 4.6.

Solution
1. Check your AC and power adapter, confirm LED Power
Indicator is ON.
2. Check the power connection into the unit.
1.
Are your phones wired into the RJ31X/CA38A data jack
(output)? To test connection, remove the RJ45 wire from
the RJ31X/CA38A data jack which bypasses the DTI-1 and
connect the phones directly to the main incoming line.
2. Check for any breaks in the RJ45 wire.
1. The green and yellow wires may be reversed, either at
the speaker or at the controller.
2. The red and black wires may be reversed, either ar the
speaker or at the controller.
1. Your ringer switch located at the front of the controller
may be set to the OFF position.
2. The yellow wire is not properly connected to either the
speaker or the controller section of the speaker.
3. One of the phones may be causing too much of a load;
unplug all phones and begin testing with one phone at a
time untill the defective phone is found.
Reverse the In and Out on the RJ45 data jack.
1. You have attached the phones on the premises in
parallel with the DTI-1 across your outgoing phone line
2. Your telephones may not be touchtone compatable. Or
the touchtone switch is in the off postition.
3. Please check the connection of the yellow wire at both
ends.
4. If you have more than one telephone line you may have
wired thewrong line to the controller.
The unit has been designed to go a maximum of 250 ft.
with a 22 gauge wire. A possible solution to gain an
additional 100ft. would be to increase the gauge thick-
ness (18 or 16). You can also double up the red and
black wires to give it the added gauge.
1. If you have more than one telephone line you may have
wired the wrong line to the controller.
2. Check the connection of the yellow wire at both ends.
Problem
Controller not responding.
Your phones don’t work.
When a door speaker is pressed, phones ring but
