5. PROGRAMMING
The PAD-3 functions are programmed with a 10-position DIP switch and six 3-position jumpers. The
following section describes each setting.
5.1 DIP SWITCH SETTINGS
The 10-position DIP switch allows you to select the following:
• How long will the unit wait before indicating a loss of AC
• Which input (Input 1 or Input 2) will control the NAC outputs
• Which outputs to wire as Style Z (Class A) and Style Y (Class B)
• Auxiliary power output operation on AC power fault
• Which outputs to operate as steady outputs or ANSI temporal
Refer to Figure 2-2 for the location of the DIP switch on the circuit board assembly.
All DIP switches are factory set for off; verify proper settings for proper system operation. Slide the
switches to the left for OFF and to the right for ON.
Note: The unit checks DIP switch settings only when reset. If you change these switch
settings, you must push SW2 reset switch to recognize the new DIP switch settings.
