DIP switches
Two of the banks of DIP switches mounted on the CAB circuit board are used to
configure alarm board functions (SW2 and SW4). The location on the board and
exact appearance varies with manufacturer.
 SW2 used to inhibit auxiliary equipment housing and optional smoke alarm
signals.
 SW4 used to inhibit or set periodicity of automated internal battery
capacity test and to set the CAB into debug mode.
Table 4-4 shows the function of SW2 individual dip switches.
