?
Total length of Control Link may be no more than 2,000 feet. This
distance is based on proper shielding on the twisted shielded pair,
and on #12 AWG wire on the wires to terminal 1 and terminal 2 of
the Control Link. If unapproved cable or smaller wire is used, this
limit is affected:
Total number of Wallstations, Control Units, Control Interfaces or
Circuit Selectors = 33 maximum.
Total number of Control Unit addresses = 8 maximum
Note: GRX-4116/4516 has 2 addresses
GRX-4124/4524 has 3 addresses
Total number of Wallstation or Control Interface addresses = 16
maximum.
Notes:
■ Make wire connections inside the wallbox and GP panel or in a
junction box (by others) within 8 ft. (2.4 m) of the terminal.
■ All control wiring is Class 2/PELV. Do not place any of these
wires in with line voltage (mains voltage) wiring.
■ The order of controls within the control wiring is not important.
