WIEEX2 (RS485) - Installation Notes
Existing 22 AWG UTP can be used between a WIEEX2 transmitter and receiver provided it is in good condition
without breaks or high impedance splices. Nominal resistance for 22 AWG UTP is approximately 18 ohms/1000
feet.
Short J1 on the WIEEX2 transmitter and receiver.
Connect the WIEEX2 transmitter (Tx) to the reader, door contact, request to exit device, auxiliary input, and
door lock, whichever are applicable.
Connect the WIEEX2 receiver (Rx) to the appropriate ACU terminals.
Power the transmitter with a 12VDC 1Amp power supply, if a local power supply is required and not sourced
from the ACU.
The Door Unlock Output (RA2/OC) is defaulted for 'fail safe'. If 'fail secure' is required on a WIEEX2 (firmware
6.00 or higher), connect RB4 on the receiver to the ‘normally closed’ position on the ACU lock relay.
The WIEEX2 transmitter (Tx) can control a lock device or relay to a maximum of 12 VDC, 500 mA.
CWIEEX2 (COAX) - Installation Notes
Existing coaxial cable can be used between a CWIEEX2 transmitter and receiver provided it is in good condition
without breaks or high impedance splices.
Connect the CWIEEX2 transmitter (Tx) to the reader, door contact, request to exit device, auxiliary input, and
door lock, whichever are applicable.
Connect the CWIEEX2 receiver (Rx) to the appropriate ACU terminals.
The Door Unlock Output (RA2/OC) is defaulted for 'fail safe'. If 'fail secure' is required on a CWIEEX2 (firmware
6.00 or higher), connect RB4 on the receiver to the ‘normally closed’ position on the ACU lock relay.
The CWIEEX2 transmitter (Tx) can control a lock device or relay to a maximum of 12 VDC, 500 mA.
