OPERATION OVERVIEW
The DBI-1 is operated by the door bell switches and automation systems that connect to the
contact closure and voltage trigger inputs. Triggers for two individual chimes (Chime
Selection 1 & Chime Selection 2) are provided for a front and rear door.
INSTALLATION COSIDERATIONS
•Included mounting wings and rubber feet provide for either table top or screw down mount-
ing (see Figure 1 on page 5).
•The included UL-listed, universal voltage power supply provides power to the DBI-1
(see Figure 2 on pages 8-9).
•The DBI-1 connects to the Paging Input of a Niles MultiZone Control System using a stan-
dard audio cable with male RCA connectors (see Figure 2 on pages 8-9).
•Apaging system connects to the Audio Input of the DBI-1 using an RCA audio cable
(see Figure 2 on pages 8-9).
•Doorbell momentary contact closure and momentary voltage triggers connect to the DBI-1
using two conductor wire (see Figure 2 on pages 8-9).
INSTALLATION
Mounting the DBI-1
Once you have decided on the location for the DBI-1 (generally near the location of the Niles
MultiZone Control System), make sure that the 12V DC power adapter and all cables are discon-
nected while mounting.
The DBI-1 can be either mounted on the back of a cabinet or on a wall using screws (not includ-
ed). Also, it can be placed on a shelf using the included adhesive rubber feet (see Figure 1 on
page 5).
Connecting the DBI-1
1. Connect the Audio Output of the DBI-1 to the Paging Input of a Niles MultiZone System
(see Figure 2 on pages 8-9).
2. (Optional) Connect the Audio Output of a paging system to the Audio Input of the DBI-1
(see Figure 2 on pages 8-9).
3. Connect the voltage and or contact closure trigger cables to the and Chime
Triggers (see Figure 2 on pages 8-9).
4. (Optional) Connect the 12V DC Voltage Trigger Output to a voltage activated device.
(see Figure 2 on pages 8-9).
5. Connect the included 12V DC in-line power adapter’s voltage output plug into the DBI-1’s
power jack and then plug its AC power cord into an unswitched AC outlet (see Figure 1).
The red LED power indicator will illuminate to confirm proper power connection.

INSTALLATION SETTINGS
Contact Closure Triggers - Contact closure trigger inputs provide for two independent
chime triggers. When triggered, the selectable trigger tone, assigned delay and chime are
executed.
3V-30V Voltage Triggers - Voltage trigger inputs provide for two independent chime trig-
gers. When triggered, the selectable trigger tone, assigned delay and chime are executed.
Note: Voltage triggers are not polarity dependent.
Chime and Audio Level Adjustments - Adjustable output level for the selected chime
and the connected paging system.
Note: The Audio Level Adjustment does not affect an audio input signal that is being
recorded for a Custom Chime. The Custom Chime record level must be adjusted exter-
nal at the audio source.
Important: Lowering the chime and audio level will prevent sound distortion.
Setting the Tone/Delay - Four DIP switches provide a selectable trigger tone and various
delays between when a chime is triggered and when the chime is actually generated.
Turning switch 1 ON enables a trigger tone that activates the audio sensing of the Paging
Input of a Niles MultiZone System. Switches 2, 3 and 4 ON enable delay times. The delay
time provided for each switch is indicated in the table below.
Delay times are summed together when multiple switches are
selected (e.g. 2 and 3 = 3 seconds). There is no delay included
if none of these DIP switches are selected.
Notes: 1. The chime contact and voltage triggers are ignored
during a chime. 2. A triggered chime is delayed 8 seconds after
the completion of a chime when a trigger tone or any amount of
delay is selected.

INSTALLATION SETTINGS (Continued)
Recording a Custom Chime - A mono analog audio signal can be recorded by the DBI-1 to
create a Custom Chime. Analog audio signals to be recorded connect to the Audio Input.
Stereo audio signals can be adapted to mono using an RCA “Y” Adapter Cable.
The DBI-1 was designed to record a Custom Chime at the same volume as the selectable
chimes when recording the output of a typical CD player (@ 2V RMS). The record level
for a Custom Chime must be adjusted externally at the audio source. Some trial and error
will be required to obtain an exact volume match between a recordable Custom Chime
and a selectable chime.
Recording an Active Audio Signal
1. Press the record button to begin recording the audio signal (the recording starts imme-
diately and the record LED flashes red).
2. The recording process will end after 12 seconds (when it is complete, the record LED
turns off). Pressing the record button anytime before the 12 seconds have elapsed also
ends the recording (the record LED turns off).
Recording a Paused Audio Signal
1. Press the record button while there is no audio signal present at the audio input. This
causes the DBI-1 to go into a record standby mode (the record LED lights solid red).
2. Activate the audio input signal. The recording will begin the moment an audio signal
is sensed (the record LED flashes red).
3. The recording process will end after 12 seconds (when it is complete, the record LED
turns off). Pressing the record button anytime before the 12 seconds have elapsed also
ends the recording (the record LED turns off).
