Example 1
The most straightforward wiring approach would be to daisy chain the devices on one run as below.
However, this is an unacceptable solution because there are 4 ‘KEN’ on a 100m length of cable. Table 2
shows that a maximum of 3 ‘KEN’ is acceptable on a 100m length of cable – the fact that one keypad is just
50m away does not affect these rules.
Example 2
This is now an acceptable solution because the ground return is shared between 2 cores of cable. Referring to
table 2, the second column shows that by doubling up the ground return it is acceptable to have up to 4 ‘KEN’
on a 100m length of cable.
Example 3
This is now an acceptable solution because there are now two separate cables connecting the devices back to
the Matrix control panel. The 100m cable is now supporting 3 ‘KEN’ and is now in accordance with table 2,
and the 50m cable is supporting 1 ‘KEN’ which is well within the limits.
