Section 3: Program Options via DIP Switch
This section describes the programming options available via DIP switch settings. The FACP can
be field programmed using option DIP switches SW1, SW2, and SW3 which are located in the bot-
tom right side of the main circuit board. A factory-installed dip switch cover, which prevents acci-
dental programming, must first be removed. Once programming is complete, the cover must be
reinstalled. Refer to the following illustration for switch locations and DIP switch placement in the
ON and OFF positions.
