CONNECTIONS BLOCK DIAGRAM
Important: When using a DSP to control the system make
sure that the DSP control signal is already outputting +V to
SK3 on the CCRM 4000 master (+2.5 to 12 Volts) before
powering the system up otherwise the DSP command will
not be recognised by the system and will fail to operate.

Installation
The CCRM 4000-C 303 is supplied partially disassembled and requires simple push
to fit reassembly. The image below shows a fully assembled unit.
To prevent unnecessary damage to the system it’s vitally important to follow
the instructions below:
1. Remove the CCRM 4000-C 303 system from its transportation box and
remove the 2 foam end caps. The transportation box and packing should be
stored as this is the best packaging to use in the unlikely event of returning
the system to your dealer.
2. Cut the tape securing the large cardboard box to the large black ceiling frame.
3. Remove the small cardboard box located under the CCRM 4000. This
contains the PSU (master only).
4. Now open the large cardboard box and remove from the packaging the
microphone and large lower bezel with bezel clamp.

To install this system a 65 mm (2.5") hole must be cut into the ceiling tile to allow the
large lower bezel, just removed from the packaging, to be fixed to the tile. The hole
should ideally be cut in the centre of the tile and must not be closer than 76mm
(3") from the edge of the tile or it will not be possible to align the CCRM 4000
support bracket over the hole.
Take the entire CCRM 4000 kit up to the final location site. Carefully align the
CCRM 4000 complete with ceiling tile bracket so that the large slot is directly
over the hole that has previously been cut in the ceiling for the bezel. Make
sure that the front and back of the bracket fits snugly over the ceiling tile “T-
Bar rails”. Secure the ceiling bracket to the T Bar rails using the supplied four
eye bolts finger tight.
65mm (2.5") Hole
Insert the bottom part of the bezel up through the ceiling tile through the hole
and slot in the tile bracket. Secure the bezel in place with the securing ring
using a 5mm Allen key.

7
Now carefully remove from the foam packing the IR sensor, remote control
and safety cable fixing kits and set aside. Next remove the top bezel
containing the magnet assembly and Tini Q microphone connector.
1. Carefully feed the Tini Q microphone connector through the lower bezel
and push fit the top part of the bezel over the lower bezel, making sure the
magnet assembly is inside the top part of the bezel.
2. Connect the microphone on to the TINI Q connector (push fit).
Any kinks or bends in the cable can be straightened by gripping the cable with your
hands and passing it through a clean dry cloth a few times. Connect the ceiling bezel
plug into SK2 on the main unit,
IMPORTANT: For safety reasons the frame to ceiling tile fixing eye bolt (2 at
each end of the bracket) are used to secure the frame in place and also used to
suspend the CCRM 4000 and bracket. It is suggested that the cable hook is
attached to the eye bolts leaving the bare wire end to a secure fixing such as a
ceiling truss or any structure capable of taking 7Kgs of weight. The cable
length is 2 Metres (78").

8
Safety harness
For safety reasons the frame to ceiling tile fixing eye bolt (2 at each end of the
bracket) are used to secure the frame and also used to suspend the CCRM 4000 and
bracket. Unravel the Y cable harnesses and attach the hooks to the eye bolts at each
end of the ceiling tile bracket.
Eye bolts fixed here
Push the free end of the cable harness through one of the holes located on the
Gripper. Now loop the free end of the cable over a secure fixing such as a ceiling
truss, eye bolt, or any structure capable of taking 2Kgs of weight. Now pass the cable
through the remaining hole in the Gripper and then pull on the cable to adjust / take
up the slack. Do the same with the other Y cable at the other end of the ceiling tile
bracket. Cable can be slackened or removed by inserting the supplied release key into
the hole as shown below:

Connections
The table below lists the pin functions for DSP control signals to the master unit.
Slave units require just a daisy cable link (standard straight RJ45 male to male cable
required) between master and slave units. Check that the DSP control signal is present
logic +2.5 to 12 Volts is required. It is important that the DSP +V command signal is already
present before powering the system up.
The logic control signal (pin 1) is an optically isolated input with a dedicated return
connection (pin 2). Voltages as low as 2.5V DC are recognised as a ‘logic high’ input
which will command the master unit (and any connected slaves) to deploy their
microphones to a preset height. A ‘logic low’ (0V DC) will command all units to raise
their microphones to the ceiling.

DSP Mute Control
As detailed on the previous page, each unit is provided with an optically isolated
open-collector output for the mute signal, which is accessed through the DSP socket
on the master. Muting of the microphones has to be performed by a DSP. If using IR
remote then it will not be possible to mute.
The drawing below represents an equivalent circuit for the mute signal which shows
how the open collector output on each Retracta is connected in parallel when the
units are connected together using the correct RJ45 connection cable.

Common Mute Signal
Common Mute Signal Return
To function correctly, the common mute signal from all units must be connected via
an external pull-up resistor (not supplied) to an arbitrary voltage (V) at the DSP as
illustrated above. The arbitrary pull-up voltage (e.g. 5V DC or 12V DC) can either be
supplied by the DSP itself (preferred option), or by an external voltage source,
although if an external voltage source is used, the 0V return must be common with
the DSP 0V.
When the microphones are not deployed, the voltage on the common mute signal
will be pulled to the common signal return (logic low at the DSP input). The DSP
input will only switch to the logic high state when all microphones are deployed and
resting at the preset height.
Note that the common mute signal must be provided with an external voltage through
a 10K Ohm pull-up resistor, the mute signal will not function without this.

Master Unit Cable Wiring Connections using a DSP
1. Connect socket (3) to the DSP making sure that all parameters are met in
accordance to the instructions shown under “Mute Control” and Logic Hi /Lo
2.5V –12V required for activation.
2. Connect the RJ45 microphone audio output to DSP audio input. If connected
to a mixer then the mute will not be detected and the microphone will always
be live. The DSP is used to mute the microphone. Note Phantom power
must be supplied to the RJ45 microphone socket.
Termination Impedance (Z switch)
On each of the units is a slide switch “Z” in a multi system 10 or more units it is only
the final slave unit that needs to have this switch ON and all other units switches
must be OFF.
On Off
IR SENSOR INSTALLATION
Mount the IR sensor in a position (ceiling or wall) where it will be convenient to see
all the Retracta movements whilst maintaining good line of site with the IR sensor.
Do not place any obstruction in front of the sensor as this will prevent operation. Drill
a 16mm (5/8") diameter hole. Pass the sensor through the hole and secure it using
the C clip. Connect the cable to the IR sensor input socket number 1 on the
Retracta unit. IR sensor has 2 coloured LED’s: Green = In programme mode, Red =
will show each time a button is pressed on the remote.

Slave wiring connections
When adding a second Retracta unit (slave 01)
1. Connect a DC supply cable between the Master and slave DC input sockets.
Make sure that the correct polarity is applied to the Phoenix plug supplied
Positive (+) Negative (-)
2. Connect socket (4) on the master to socket (3) on the slave unit using an
RJ45 straight through cable. If further slaves are connected then link between
socket (4) and socket (3) of the next slave and so on (daisy chain).
3. Bezel cable. Connect the cable to socket (2) on the slave.
4. Connect the DSP microphone audio input to the RJ45 audio out socket.
5. Make sure that the “Units” decimal rotary switch is set to “1” (01)
Further Slave wiring connections
1. Up to 99 Slaves can be linked together in the same / identical way as
described above under “adding a second cable Retracta”.
2 Repeat the same instructions shown under heading of Slave wiring
connections and link between / daisy chain between sockets 3 and 4 of each
slave unit.
3 Make sure that the “Units” decimal rotary switch on each subsequent slave
units are set to “2”for the 2nd slave, “3” for the 3rd slave etc etc....

IR Remote control operation
The remote is primarily intended to allow the initial programming of the desired
height for each individual winch in the system. The preferred operation is then by
logic input from a DSP logic high of 2.5V to 12V is required to release microphone to
programmed height and a logic 0 low will raise the microphone. The IR remote
Up/Down buttons can be used if a DSP is not used. Open the battery compartment
pull and remove the battery insulator / protector.
IR Remote Layout
Aux: Used to programme the remote.
Up: Used to rewind cable upwards.
Down: Used to deploy cable downwards.
Enter: Used to complete / store a programme.
Setup: Only used to programme the remote.
Numeric buttons: Used to input Master / slave
designation and programme remote.
The red LED indicator shows with each press of any button. If the LED fails to light
then replace the battery.
Replacement battery type: Lithium 3V CR2025
WARNING: DANGER OF EXPLOSION DO NOT BURN OR INCINERATE THE
BATTERY.
Warning: Do not use both the IR Remote control and DSP together it will not
work. The microphones must be at the ceiling bezel then use the remote or DSP
to operate the unit.
Remote code 0515
When the battery is replaced it
may be necessary to re code the
remote. Press Aux, Press and
hold Setup until red led lights,
enter 0515 on the key pad.

IR REMOTE CONTROL ADDITIONAL INFORMATION
When programming an incorrect address code for example 32 when there are
only 3 units connected it will just be ignored / nothing will happen if either the
up-arrow & down-arrow keys are then pressed. Wait 5 seconds and re enter
the correct address code.
During initial programming of the cable height the Up & Down buttons work on
a press and hold basis, where the microphone will continue to move either up
or down all the time the button is pressed. The cable will stop when either
button is released.
If there is a pause of longer than 5 seconds between button pressing before
the ENTER button is pressed the sequence will need to be started again from
the beginning. Once the green programme LED is lit there is no time out limit.
A green LED will light on the IR sensor to indicate that programme mode has
been entered. The LED will extinguish when you exit the programme mode
(press Enter). Thereafter each time a remote button is pressed a red LED will
flash indicating a command has been received and the transmitter is in range.
IR range is approximately 7.5M (25 feet). Do not use the IR remote control if a
DSP is being used to operate the Retracta. Only use the IR remote for setting
the height after installation.
Do not mix IR and DSP operation together i.e. when microphones are at the
ceiling bezel if IR is used to deploy the microphones then the IR must be used
to retract the microphones. If the microphone is at the ceiling bezel and DSP
is used to deploy the microphones then the DSP must be used to retract the
microphones.

16
Programming cable height on master unit
The remote control is used to set up the cable height and also to deploy and retract
the microphone. For a single unit installation (Master) this has already been factory
defaulted to Master (Master unit decimal code setting is 00)
Point the remote at the IR receiver and press 00 followed by the ENTER
button (green LED will light on the IR sensor showing it’s in programme
mode). Press the Up / Down buttons on the remote set the correct height of
the microphone, press the ENTER button to store this height position into
the memory (green LED will go out). Immediately afterwards the microphone
will retract to the ceiling bezel to confirm that the operation has been
successful.
Test by briefly pressing the Down button on the remote and the microphone
will move down and stop at the programmed height. Press the Up button and
the microphone will retract back up to the Bezel. If an incorrect height has
been programmed then repeat the above instructions.
Programming cable height on a second unit (slave designation 01)
Make sure 01 has been selected on the slave “unit.

17
Point the remote at the IR Sensor press 01 followed by the ENTER button (green
programme LED on the IR sensor will light). Press the Up / Down buttons on the
remote set the correct height of the microphone, press the ENTER button to store
the desired height in the memory (green LED will extinguish).
Immediately afterwards the microphone will retract to the ceiling bezel to confirm that
the operation has been successful.
Briefly press the Down button and the microphone will drop down and stop at the
programmed height. Press the up button and the microphone will retract back up to
the Bezel. If an incorrect height has been programmed then repeat the above
instructions
Programming multiple units
As each additional slave units is added it will be necessary on each of the slaves to
change the “units” decimal rotary address switch to “2” for the 2nd slave / “3” on the
3rd slave etc… then as described above repeat the button sequences on the remote
to set each of the cable heights on each of the slaves in turn. Don’t forget to enter
the slaves assigned number on the remote (02 or 03, 04 etc) before completing the
programming sequence. If 10 or more Retractas are being used then it will be
necessary to change the Tens rotary address on the 10th slave to “1” and Units
rotary switch to “0” (10), for the 11th slave select “11” and so on. If you have now
completed the installation of several Retractas you can now check that all cables are
deployed simply by pressing the down button.
NOTE: If the cable hits an obstruction such as a desk / floor or is held preventing the
upward motion (0.5lbs pull) of the cable motor will immediately stop. Remove the
obstruction and then press the up or down button on the remote, or up or down
command if using a DSP. The unit can now be operated normally. Should this fail to
restore normal operation disconnect and reconnect the supply Voltage to the CCRM
4000-C 303.
