Introduction
The BT-1 is a wireless remote audio input module for use with all Cloud products fitted with an RJ45 Facility Port or an RJ45
Extension Port.
The BT-1 enables compatible portable devices such as laptops, tablets and smartphones to stream audio wirelessly to the
interface, and thus into the audio system of the Zone where the interface is installed.
The BT-1 is connected to the host unit’s Facility Port or Extension Port by a single Cat 5 cable. Alternatively, it may be connected
to remote Cloud input modules such as the LM-2, LE-1 and BE-1 in “daisy-chain” fashion, these modules being connected in
turn to the host unit. Screened Cat 5 cable and shielded RJ45 connectors should be used in all cases. If the Zone where the
BT-1 is installed also requires RL and RSL Series remote control plates, they may be “daisy-chained” to the BT-1 instead of being
connected to the host unit, which will simplify installation wiring in many cases.
BT-1 variants
There are two primary variants of the BT-1: the BT-1F, suitable for use with host units fitted with one or more Facility Ports, and
the BT-1E, suitable for use with host units fitted with one or more Extension Ports. The BT-1F will route an (L+R) mono sum of
the streamed audio to the host unit; the BT-1E routes the audio in stereo.
Variant BT-1F may be used with the following Cloud products, which are fitted with Facility Port(s):
•
Z4

Variant BT-1E may be used with the following Cloud products, which are fitted with Extension Port(s):
•
DCM1
Digital Control Zone Mixer
•
DCM1e
Ethernet Digital Control Zone Mixer
BT-1E and BT-1F variants may be distinguished physically by an ident on the rear PCB: a black mark will be visible in one of two
checkboxes:
•
DCM1
: BT-1E
•
FACILITY
: BT-1F
Additionally, the BT-1 is available in two form factors to suit either UK single-gang or US standard dual-gang electrical back
boxes; US-size modules are denoted by a suffix ‘A’ to the Part No.
UK-size modules are available either in white (a further suffix ‘W’ to the Part No.), or black (suffix ‘B’) finish.
NOTE: Unless specifically stated otherwise, all references to “BT-1” in this Installation Guide can be taken to apply to all BT-1
mechanical and cosmetic variants.
Mounting - mechanical
BT-1 (UK version)
The Cloud BT-1 (BT-1FB, BT-1FW, BT-1EB, BT-1EW) fits a standard UK-style single-gang electrical back box. The box used should
have a depth of at least 35 mm.
BT-1A (US version)
The Cloud BT-1A (BT-1AFW, BT-1AEW) fits a standard US dual-gang electrical ‘J’ box in vertical orientation. The box used
should have a depth of at least 1½”.

Pressing the button for 2 secs puts the BT-1 into “Awaiting Pairing” mode. The BT-1 will be visible on the scan list of
external wireless devices within range for 30 seconds; during this timeout period, an external device may initiate pairing.
Once paired, no other device can connect to the BT-1. The
STATUS
LED [2] blinks blue/green in Awaiting Pairing mode.
If no device connects during the timeout period, the BT-1 reverts to “Secure” mode, preventing a connection to be made
by new devices.
Long press:

Pressing the button for 5 secs puts the BT-1 into “Factory” mode. This clears any active connection and the BT-1 will not be
visible on any external devices’ scan lists (unless the BT-1 is in Unsecured mode – see “Secured and non-secured modes”

Installation - connections
Connection to a Facility Port (BT-1F only)
The BT-1 has two PCBs “piggy-backed” onto the rear of the faceplate. The RJ45 output connector (SK1) is located on the upper
PCB:

IMPORTANT:
Because the cables carry low-level audio,
only
screened Cat 5 should be used, the foil screen of the cable being

may
be
possible to use ready-made screened Cat 5 “patch” cables of short length. In all other situations, shielded RJ45 plugs should be
crimped onto the installed screened Cat 5 cable using the pinout shown below.

The audio streamed to the BT-1F module will be available in the Zone as soon as the module is connected to the host unit’s
Facility Port for that Zone. Audio fed into the Zone will be an (L+R) mono sum of the stereo audio streamed from the user’s
wireless device (e.g., smartphone, tablet, etc.). Audio volume will be controlled solely from the user’s device in the normal way
and will be unaffected by any of the host unit’s front panel controls.
* There is no reason why the module cannot be connected to the Facility Port of a Zone other than that in which it is installed – though this is unlikely to be
an common installation scenario.

the chain. Note that as the BT-1F has no Link connector, it must always be the last module in a chain.
For details of how to configure a Facility Port to operate correctly with an LM-2 Remote Input/Control Module, please see the
LM-2 Installation Guide.
Connecting a BT-1E to an LE-1 or BE-1
If a BT-1E is being installed in a Zone which also contains an LE-1 or BE-1 Remote Input Module, it should be connected to the

Connecting an RL/RSL plate to a BT-1F
The BT-1F is provided with a 3-pin screw-terminal connector (on the rear PCB) to permit the connection of an RL-1 or RSL-6
remote control plate. These plates normally connect to the Music Control Port for the relevant Zone at the host unit, but it
may simplify wiring to connect one to the BT-1.

Set-up Options
Setting up the BT-1 is very simple: there are two 4-way DIP switches on the lower rear PCB which may need to be set to
configure the BT-1 to suit the specifics of the installation.

Secured and non-secured modes
Normal operation of the BT-1 will be with “Secured” mode selected: this requires the user to press the
PUSH-TO-PAIR
button to place the module into “Awaiting Pairing” mode, and then to initiate pairing from his/her portable wireless device
within 30 seconds.
Under some circumstances, it might be preferable to select “Non-secured” mode to circumvent use of the
PUSH-TO-PAIR
button, giving any user within range the ability to connect to the BT-1.
“Secured” mode is selected by setting SW1 of the left-hand DIP switch (as seen from the rear of the BT-1) to ON (switch
down). With SW1 OFF, the BT-1 is in “Non-secured” mode.
BT-1 Installation Guide v1.0
13
RF power setting
The RF power level at which the Bluetooth interface operates – and hence the operational range of the BT-1 – is adjustable.
Units are shipped with the power setting at maximum, but in some installation circumstances, it may be desirable to limit the
power of the module, thereby restricting the operational range. Typically, it may be necessary to do this where there are BT-1
modules installed in adjoining rooms, as it reduces the likelihood of the BT-1 in one room appearing in the Device List on
smartphones, tablets, etc., in other rooms.
The power level is set by SW2, SW3 and SW4 on the left-hand DIP switch (as seen from the rear of the module). The three
switches work in a binary manner, thus eight power levels are theoretically available, though this is limited to seven in practice.
The power levels are in 4 dBm steps. The table below lists the available power settings:

Bluetooth ident
In installations where multiple BT-1s are installed, it will generally be desirable to give each a unique identifier. The right-hand
DIP switch (viewed from the rear) allows one of 16 idents to be assigned to each BT-1.
The BT-1 appears in the Device List on a user’s laptop, tablet, etc., with a numeric suffix (#01 to #16) to indicate all the BT-1s
that are within range; in this way, the user can be certain of connecting to the intended module. It is recommended that installers
affix a printed label to each module to indicate the ident set, in such cases.
The idents are selected by the four sections of the DIP switch using binary weighting, as shown below:

Operation
When the BT-1 first has power applied to it, the
STATUS LED flashes alternate green/blue for a few seconds to confirm
correct operation.
Normal (“Secured”) mode:
In Secured Mode, the module will appear in the Bluetooth Device List of any smartphone, tablet, etc. within range. At this
time, no connection will be in place, and it will not be possible to pair with the BT-1.
To initiate pairing, press the
PUSH-TO-PAIR
button for two seconds; the
STATUS LED will flash alternate blue/green
for 30 seconds, indicating “Awaiting Pair” mode. During this timeout period, a user can select the BT-1 from his/her Device
List, and if pairing is successful, the
STATUS
LED will turn steady green. The BT-1’s ident will now not be visible on other
Device Lists, and therefore it will not be possible for any other device to connect to it. In order for another device to
connect to the BT-1, the current device must first disconnect.
Streaming may now commence: on receipt of audio data, the
STATUS
LED turns blue.
Disconnection may be achieved in three ways:
•
from the user device – the connection is cancelled and the
STATUS
LED goes out. The BT-1’s internal “User List”
will retain the identity of the user’s device, in which case, that specific user will be able to reconnect at a future time
without the
PUSH-TO-PAIR
button being pressed.
•
from the BT-1 itself, by pressing the
PUSH-TO-PAIR
button for two seconds. This has exactly the same
consequences as cancelling the connection from the user device.
•
From the BT-1, by pressing the
PUSH-TO-PAIR button for five seconds. This places the BT-1 in “Factory” mode
and clears the internal “User List”. Any device that was previously connected to the BT-1 will need to reconnect
with the use of the
PUSH-TO-PAIR
button as described above.
BT-1 Installation Guide v1.0
15
Non-secured mode:
In Non-secured mode, it is not necessary to initiate a connection with the
PUSH-TO-PAIR
button. The BT-1 will “pair”
with the first device that requests pairing. Once pairing is established, no other device can connect to it, in the same way
as in Secured mode.
Streaming may now commence: on receipt of audio data, the
STATUS
LED turns blue.
Disconnection may be achieved by any of the three methods outlined above for “Secured” mode.
Power considerations
The BT-1 will operate from a DC power supply in the range 12 V to 24 V. This will be supplied by the host unit’s Facility Port
or Extension Port via the Cat 5 connection: Cloud Z4/Z8
MK3
host units supply +/- 15 V from their Facility Ports while the
Z4/Z8
MK4
and 46-120 host units supply +/-12 V. The DCM1 range supply +/- 12 V from their Extension Ports.
The BT-1 consumes 20 to 26 mA from the host unit’s power supply. In the majority of installations, the host unit will have ample
spare current capacity to power one or more BT-1s. However, installers should note that this may not be the case in a very large
system with multiple remote modules in several Zones. If there is any doubt about the power capability, please refer to the host
unit’s Installation and User Guide where full details of power supply ratings can be found.
