9. TROUBLE SHOOTING

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 defec-
tive 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 touch-
tone 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 the
wrong 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 thickness (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 you have
no audio communications to the door.
The DTI-1 Doorbell Telephone Interface works but the
phones don’t ring when the speaker button is pressed.
You have a dial tone feedback at the speaker when door
speaker button is pressed.
When pressing
*
#
*
(for monitoring the door) you get
an operator recording (eg. “this is an invalid number”) and
you have no communication to the speaker.
On a gate installation, you have no audio
communication to the speaker.
Telephone does not ring when door button is pressed.
10. TECH TIPS
When the DTI-1 system is using the TPM-1
Paging Module and there is no TDB-1 being
used, a 300 Ohm resistor is required for the
audio circuit to be completed to the TPM-1.
The following diagram shows the placement
of the resistor in series with the two outer
conductors of the RJ-11 connector
(Yellow/Black).

A pause of at least one half second is
required for the system to first recognize the
communication request (

command is given to activate the paging
module.
