Searchpoint Optima Plus or Searchline Excel Wiring Recommendations
When wiring the XNX transmitter and the Searchpoint Optima
Plus or Searchline Excel for remote applications, the general
recommendations of the ANSI/TIA/EIA-485-A standard must be
adhered to with the following additions:
1� When mounting the Searchline Excel or Searchpoint
Optima Plus, run wiring connections between each Excel
or Optima and the transmitter in a dedicated separate
conduit�
2� Use 18 AWG twisted shielded cable for the RS485
connection between Excel or Optima and the XNX� Make
sure that the shield of the cable is grounded to earth and
XNX ground on one end ONLY�
3� Avoid running wiring near main cables or other high
voltage equipment�
4� Do
not
apply 120 ohm terminating resistors� These
resistors are not required due to low data rates�
5� Honeywell Analytics recommends that Excel or Optima
sensors and the XNX transmitter be wired to building
ground� The system should be grounded at one point only�
INSTALLATION TIP:
Always perform a soft reset after connecting the Searchpoint
Optima and XNX transmitter for the first time� The soft reset is
performed by accessing the transmitter’s Calibration Menu�
