Battery Maintenance
•
When the control panel shows an alarm signal for “Low Battery”, check that the battery switch is turned on,
and the battery is charged. After one week of charging, recheck the battery capacity. If normal, the battery
should be in full capacity. If the capacity is still low, continue changing the battery. If the battery is not
charging, contact Nuaire.
•
The battery that supports the power outage alarm is a consumable item. The life expectancy for the lithium
battery is 5 years (Lead-acid battery is 2-3 years). If the battery is more than 5 years old (Lead-acid battery 2-
3 years), the battery should be replaced because the alarm function may not work properly. Contact Nuaire
for assistance.
