Use the Auxiliary Switch (AUX SW) output terminals on the

PM-30

. If shutting down power to an external device is sufficient,

then connecting to the Auxiliary Switch (AUX SW) terminals on the

PM-30 power module ensures power is cut off when the LoLo alarm

is triggered. This may be the preferred solution if the ROC800

provides critical controls. When the LoLo alarm is triggered and the

ROC800 CPU goes into sleep mode, it cuts power to the Auxiliary

Switch (AUX SW) terminals.
