EXAMPLE WIRING DIAGRAM
Figure 4 shows an example wiring diagram for a system using
two SEC-H-INT-KP SmartKeys. Note in this example,
SmartKey #1 is installed at the end of the RS-485 buss, on
which the security controller is daisy-chain connected on its
NPB-2X-485 option connector. From there, this SmartKey
buss continues on one pair of a 2-pair cable run to the SEC-H-
R2R module (the other pair is used for RS-485
communications between the security controller and its
expansion modules).

After completing wiring terminations and restoring power to
the security controller, the LCD display on the SEC-H-INT-KP
SmartKey should display time, and keys should be backlit in
blue. This verifies power to the SmartKey.
To verify RS-485 communications, refer to the WEBs AX
Security User's Guide for setup procedures.

From the SEC-H-R2R module, another 2-pair cable is run to
the SmartKey #2 unit, which allows for RS-485 "multidrop"
wiring (using one pair to return back to the SEC-H-R2R
module). Wiring can continue in this fashion to other SEC-H-
R2R modules and SmartKey units, if needed.
