Cabling Keypads and Expanders
Cooper Security recommend that you use 8-core 7/0.2 or 16/0.2 alarm cable
for wiring keypads and expanders.
You can connect the keypads and expanders in either a star or bus configu-
ration (see Figure 5). If you are intending to use long cable runs then Cooper
Security recommend that you use star wiring with no more than 200m of
cable per branch.

Figure 5. Star and Bus Wiring for Keypads and Expanders
The maximum length of any one run from control unit to the most remote
keypad or expander depends on the number of items connected to the cable.
You can double the maximum length by using two cores each for the 0V and
12V terminals or by using 16/0.2 cable. The table below shows the maximum
recommended cable lengths in metres for 7/0.2 cable, assuming that you
connect all items at the end of a single cable run. (An item is either a keypad
or an expander.) In real life you may be able to improve on these figures by
spreading items along the cable length (figure 5).

It is possible to extend the keypad cable run by using additional power
supplies, but only up to a recommended maximum of 200m
When carrying out the cabling there are two important points to remember:
