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 6). If you are intending to use long cable runs then Cooper
Security recommend that you use star wiring.

Figure 6. 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 or triple the maximum length by doubling or tripling the
number of cores attached to the 0V and 12V terminals of each item. The
table below shows the maximum recommended cable lengths in metres,
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 6).

When carrying out the cabling there are two important points to remember:
1. Do not connect anything other than keypads and expanders to the keypad
bus. The keypad bus power supply is limited to a maximum of 400mA and
can supply no more than a maximum of four keypads and four expanders.
