B&K CK1.1 Manual To Installation - And/or

Connecting To A CT Receiver

Keypads connect to the CT Receiver at the Zone Control terminals. There is

one terminal for each hardware zone labeled A-F on the CT600 and A-C on

the CT300.

You can terminate the Keypad cables to the Control terminals in one of two

ways:

1. If your cables are already terminated in RJ-45 plugs,

order the accessory “Terminal Block to RJ-45 Adapter” 

(P/N 21419) separately from B & K . 

Plug the RJ-45 plug into the adapter

and screw the adapter in place on the

CT Receiver. Be sure to match the

labels on the back panel to the labels under the pins

of the adapter.

AND/OR

2. You can strip the keypad cable and terminate five of the wires to the five

pin phoenix plug. If you are using CAT5 cable connected to the RJ-45 at the

Keypad, there are extra connections for Ground and 12V. These can be left

unterminated (though it does no harm to connect them). It is not important

that you use any particular color scheme, only that you connect one to one

as described here:
