1.INTRODUCTION
1.1.SAFETY
Mains power wiring is dangerous.A suitably qualified person
should install the system.Reference should be made to BS
& any other local wiring requirements Before working on
this system or altering any of the options,isolate the Master
Switcher CM6 and Slave Switcher CS6 units from the
electricity supply.When the supply is hard wired turn off the
local isolator and preferably remove the fuses.Ensure that all
staff know that you will be working on the system.If power
is supplied from a pluggable source, remove the plug.
This unit should be fitted in a suitable enclosure (19”rack)
to restrict access to the wiring terminals.
1.2 DESCRIPTION
The system allows mains powered electrical equipment to
be turned on and off in a particular sequence.Instructions
to initiate the sequence are input via a coded keypad.The
CR6 Remote Panel allows control from a location remote
to the CM6 Master Unit.The CM6 Master Unit contains all
the control electronics together with the first two sequential
power outputs.A further 8 low voltage outputs are available
to control CS6 Slave Units.
2.INSTALLATION
2.1 FIXING
All units are designed for mounting in a standard 19”rack.
2.2 KEYPAD DE-SELECT
When a CR6 Remote Panel is fitted to a system it is
sometimes necessary to prevent the keypad on the master
unit being able to operate the system.This can be achieved
by cutting a wire link on the keypad PCB in the master unit.
This link is situated on the LED end of the front panel PCB
and is accessible without removing the board from the unit.
This link only prevents the keypad from operating,it does
not disable the LED’s so that the system status can be
checked.
3WIRING
To give complete control and maximum security a 9 wire cable
is required to connect the remote panel to the master unit.
Wiring between the barrier strips is 1 to 1,2 to 2 etc.
Connecting cables can be any suitable low voltage type,
e.g.burglar alarm or telephone.The use of spade crimps is
recommended.Low voltage cables should be segregated
from power (mains) cables.
It is possible to use the system with a reduced number of
wires in the control cable but this does allow the‘cracking’of

the code to be a lot easier and reduces the flexibility when
code changing.The wire coinciding with a key which does
not appear in the set code need not be run,e.g. if the set
code is 3642 then the wires corresponding to keys 1 & 5
need not be used.The barrier strip numbering corresponds
with the keypad number,i.e.barrier strip terminal 1 controls
key 1 etc.Wires between strip numbers 7, 8 & 9 MUST be
connected.
4.OPERATION
On first connecting power,the system will be‘OFF’.Upon
entry of the correct combination (code), the code accept
LED (marked‘ON’) will illuminate.After approximately 10
seconds,Output 1 and Output 1 LED on the CM6 Master
Unit will turn on.After approximately another 10 seconds
Output 2 and Output 2 LED will turn on.This sequence will
continue until all connected outputs have latched on.During
the turn-on sequence no‘OFF’code will be accepted.
After entry of the first correct digit of a code the rest of the
code must be entered within 5 seconds or the code will be
rejected.If an incorrect code is entered then wait about 10
seconds before trying again.
Once the‘ON’cycle has been completed,entry of the
correct code will start the turn-off sequence i.e.turn-on in
reverse.
Similarly to the‘ON’sequence the‘OFF’sequence will not
accept an‘ON’code until the system has completed its cycle.
If there is a loss of power the system will reset to‘OFF’.
5TROUBLESHOOTING
OFF or ON LED litWrong code or link Check code & allow
but does not change cut on keypad PCB 20 secs between
tries on entry of code Some items of equipment that are
fitted with combined circuit breaker and ON/OFF switches
do not reliably turn on remotely i.e.when the item is left
turned on and the supply is connected.There is no solution
to this problem apart from removing the offending circuit
breaker;this is not recommended.
Note:These instructions apply to the installation and use of
the CR6 remote keypad unit.

Switcher unit CM6 for full details of the complete switching
system.
