the terminal voltage is lower than the standard voltage, charge the battery
immediately. Generally, charge the battery once every three months.
● When the re suppression equipment is stored as spare parts, the ambient
temperature should range from 0°C to 50°C and the humidity should be less
than or equal to 95% RH.
Outside China:
● At a room temperature (about 25°C), charge the backup battery of the
extinguishant control panel at least once every six months. The charge
interval is halved at each additional increase of the temperature by 10°C.
● When the re suppression equipment is stored as spare parts, the ambient
temperature should range from 0°C to 50°C and the humidity should be less
than or equal to 95% RH.
Storage Requirements for a Smart Rack Controller
