4.0 Six-Wire Bus

This section looks briefly at Readykey’s proprietary

communications link between controllers - the six

wire bus. In it, we’ll look at:

• Cable specifications for the six-wire bus.

• Possible configurations.

• Controller addressing.

The six-wire bus is Readykey's proprietary

communications link for locally connecting door

controllers. It uses up to 3000 ft. (1000 m) of

standard, unshielded signal cable to connect door

controllers. No single length of cable should be

longer than 1500 ft. (500 m).

4.1 Cable Specification

Readykey recommend that you use multi-stranded,

unshielded, 6/8-conductor 24 AWG (0.5 mm /

0.22mm²) alarm or signal cable. If you do use

shielded cable, you should reduce the maximum

distance by 2 to 3 times depending on the

capacitance of the cable.

This is a linear bus and, where possible, should be set

up as shown in the following diagram. The total

length of the bus should not exceed 3000 ft. (1000

m), and no single length should be longer than 1500

ft. (500 m).

Note:

Branches/spurs are allowed provided they are no longer

than 33 ft. (10 m) in length. The length of the spurs

should be included as part of the overall length. A

maximum of four spurs recommended.
