What's in the box?
1 - Made in USA BT287
1 - 15V power supply PN PS27s
1 - This owners manual SPECIFICATIONS:
Output Impedance: 1K Ohm RCA
Power Requirements: 15 VDC, 500 mA;
Rolls part number PS27s
Size: 3.75” x 3.25” x 1.5”
Weight: 1 lb.
DESCRIPTION:
To pair a device to the BT287 simply nd
the BT287 (ROLLSBT) on your device
and connect. After the device is connected
to the BT287 a steady blue led will light
indicating that the BT287 is paired to a
device, but no audio is present. A slow
blinking blue light indicates that audio is
being sent when paired.
When powered o󰀨 the BT287 will remem-
ber the device it was previously paired
with. On power up will search for that
device and reconnect to it.
The DB287 has a Bluetooth operating
range of 15 to 40 feet depending on how
and where it is installed.
The Rolls BT287 is a Bluetooth interface that
will supply stereo or mono audio to a sound
system. It also features a 400 watt contact
closure relay for activation of the connected
system. For example, if you have a sound
system such as an old juke box and want to
add Bluetooth capability to it. The BT287 will
supply audio to the juke box as well as pro-
vide a contact closure relay to turn the juke
box on, controlling cabinet lights, amplier and
audio level remotely. When audio is sent to the
BT287 the juke box will turn on automatically
and start playing audio, when Bluetooth audio
is not present the juke box will be powered o󰀨
by the BT287. This way a homeowner or shop
owner could have a piece of equipment (juke
box) remotely controlled via laptop, phone,
tablet or other digital Bluetooth device with the
BT287.
OPERATION:
Power Switch and LED
power indicator.
RCA Stereo outputs
Level control to set
RCA output level.
Radome - Bluetooth
antenna cover and
blue status led.
NOTE: The radome
should face the direc-
tion of the Bluetooth
signal source to get
the best range.
Mono Stereo
switch for output
N/C C N/O: 3 pin plug able
barrier for the relay connec-
tion the relay terminals are:
N/O=normally open
C=common
N/C=normally closed
The BT287 has an internal
4A fuse.
NOTE: The relay circuit is
input sensitive. If the audio
being sent to the BT287,
or the level of the BT287 is
set to a very low level the
threshold might not be met
for the relay to activate.
Setting both levels higher
will allow the BT287’s relay
to operate properly.

The BT287 should be installed by a knowledgeable sound installation professional that is familiar with electron-
ic installations. Since hazardous voltages may be present on the control contacts, only people familiar with the
hazards of such devices should attempt installation.
When in use the BT287’s internal relay (N/C C N/O ) will close (or open if needed) within milliseconds of a Blue-
tooth audio input signal sent, then 20 seconds after the audio signal stops playing the relay will switch even if
Bluetooth is still paired to a device. The BT287 senses the level of audio signal for switching its relay.
NOTE: the controlled device may have a warm up time after being turned on, delaying audio being played.
