a. GE recommends using shielded cable for all installations.
Belden 8725 or equivalent, 20 AWG minimum
Maximum cabling distance
WIU-2 to controller:
b
WIU-2 to Reader:
c
b. WIU-2 to Controller: The maximum cabling distance of 1,000 ft (304.8 meters) is
influenced by wire gauge, reader power requirements, and the 12 VDC level
from the controller.
c. WIU-2 to Reader: The maximum cabling distance of 250 ft (76.20 meters) is
influenced by wire gauge, reader power requirements, minimum input voltage
at the reader when using the 12 VDC from the WIU-2 (originally from the
controller), and the cabling between the WIU-2 and controller.
1000 ft (304.8 m) @ 12 VDC with 20 AWG cable
250 ft (76.2 m) @ 12 VDC with 20 AWG cable
Door strike relay
d
d. The life of the relay decreases as the current switched by the contacts is
increased. Use low current door strikes to maximize the relay life. Use an
external relay for high current or high traffic applications.
