NpmDualBatteryPlatformService (PowerMonitorService) applies to a station running in a JACE platform that is capable and enabled for “dual battery” support, such as a JACE-x02 Express series (M2M JACE). It is used to monitor primary power status and backup battery levels in both the onboard NiMH battery as well as the optional sealed-lead acid (SLA) battery. A few configuration parameters allow changing the shutdown delay time, as well as alarm source configuration for all three types of alarms (low NiMH battery level, low SLA battery level, primary power lost).

Typically, support is enabled and configured at JACE commissioning time. For related details, see “JACE power monitoring configuration” in the latest JACE Niagara 4 Install & Startup Guide.
