Wiring the TouchCenter
Connect TouchCenter in parallel with keypads and other peripheral
devices using the keypad data (ECP) bus. Determine wire gauge by
referring to the Wire Run Length/Gauge table below.
Wire Run Length/Gauge Table
Wire Gauge Length
#22 gauge 150 feet
#20 gauge 240 feet
#18 gauge 350 feet
#16 gauge 550 feet
If more than one keypad is wired to one run, then the above
maximum lengths must be divided by the number of keypads on the
run (e.g., the maximum length is 75 feet if two keypads are wired on
a #22 gauge run).
Unshielded 4-conductor cable is recommended for the power/data wire.
