NTI SERVER ENVIRONMENT MONITORING SYSTEM

BATTERY BACKUP

ENVIROMUX has a rechargeable sealed lead-acid battery backup that will prevent the monitoring system from shutting down in
the event of a power failure. Should a service power failure occur, the ENVIROMUX will continue to operate as normal for
1 hour under full load and approximately 30 minutes after the "Low Bat" LED on the front panel (page 53) illuminates.
When the battery is not being used, it is being charged as long as line power is provided. It will take 32 hours for the battery to
fully charge from a fully discharged state. While charging the "Low Batt" LED will be solid ON.
If the power is ON and the battery is fully charged, the "Low Batt" LED will be dark.
If the battery fails to charge or if the battery's output voltage drops from 12VDC to below 10.7 volts, the "Low Batt" LED will blink.
The battery will automatically be disconnected from the system. If this happens, the battery must be replaced. Contact NTI to
arrange for return and service.
Note: If the power switch is turned OFF while still plugged into line power, the ENVIROMUX will sense this and not
engage the backup battery.
