INSTALLATION CONSIDERATIONS
• Included mounting wings and rubber feet provide for either table top or screw down
mounting (see Figure 1 on page 7).
• The included UL-listed, universal voltage power supply provides power to the DBI-1
(see Figure 2 on page 10).
• The DBI-1 connects to the Paging Input of a Niles Multi Zone Control System using a
standard audio cable with male RCA connectors (see Figure 2 on page 10).
• A paging system connects to the Audio Input of the DBI-1 using an RCA audio cable
(see Figure 2 on page 10).
• Doorbell momentary contact closure and momentary voltage triggers connect to the
DBI-1 using two conductor wire (see Figure 2 on page 10).
• A single constant Voltage Trigger Input to support a Lighted Doorbell Button.
(see Figure 3 on page 11).
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
disconnected while mounting.
The DBI-1 can be either mounted on the back of a cabinet or on a wall using screws (not included).
Also, it can be placed on a shelf using the included adhesive rubber feet (see Figure 1 on page 7).
CONNECTING THE DBM
1. Connect the Audio Output of the DBI-1 to the Paging Input of a compatible Niles MultiZone
System (see Figure 2 on page 10).
2. (Optional) Connect the Audio Output of a paging system to the Audio Input of the DBI-1
(see Figure 2 on page 10).
3. Connect the voltage and or contact closure trigger cables to the Chime Triggers
(see Figure 2 on page 10).
4. (a) (Optional) Connect the 12V DC Voltage Trigger Output to a voltage activated device.
(see Figure 2 on page 10).
(b) Connect the 12V DC Voltage Trigger Output to Door number one’s (1) Voltage Trigger Input in
parallel with the two conductors that are to power the Lighted Doorbell Button.
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 on page 7).
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 triggers. When
triggered, the selectable trigger tone, assigned delay and chime are executed.
When in Lighted Doorbell Mode the DBI-1 ’s door number one input requires a constant Voltage
and the collapse of that voltage initiates the chime. Use the DBI-1 ’s Trigger output to provide voltage
to illuminate a single Lighted Doorbell Button. (See Figure 3 on page 11)
Lighted Doorbell Mode - Press and hold the Record Button for 10-15 seconds, the Record LED
will blink three (3) times. This will indicate door number one (1) has been placed in Lighted doorbell
Button Mode.
The Voltage Trigger output will now be outputting a continuous voltage that will provide the 12V to
illuminate the button and Door number one’s (1) Voltage Input.
NOTE: 1. DO NOT USE THE AC POWER DISTRIBUTION IN AN EXISTING DOORBELL SYSTEM. 2 PRESS
AND HOLD THE RECORD BUTTON FOR 10-15 SECONDS, THE RECORD LED WILL BLINK TWO (2)
TIMES AND THIS WILL RESTORE THE DBI-1 TO ITS ORIGINAL SETTINGS.
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 NCT AFFECT AN AUDIO INPUT SIGNAL THAT IS BEING
RECORDED FORA CUSTOM CHIME. THE CUSTOM CHIME RECORD LEVEL MUST BE ADJUSTED EXTERNAL
AT THE AUDIO SOURCE. IMPORTANT: LOWERING THE CHIME AND AUDIO LEVEL WILL PREVENT SOUND
DISTORTION.

INSTALLATION SETTINGS (Continued)
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 6 SELECTED.

INSTALLATION SETTINGS (Continued)
Chime Selection - Two banks of DIP switches (Chime Selection 1 and Chime selection 2) provide in¬
dependent selection of all the available chimes. The lowest number DIP switch takes priority if more
than one switch is selected. The table below identifies the selectable chime for each DIP switch.
1
Standard Chime Recommended for a Front Door
2 Westminster Chime Recommended for a Front Door
3 Standard Chime Recommended for a Rear Door
4
Westminster Chime Recommended for a Rear Door
None Recorded Custom Chime
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.
INSTALLATION SETTINGS (Continued)
RECORDING AN ACTIVE AUDIO SIGNAL
1. Press the record button to begin recording the audio signal (the recording starts
immediately 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).
