For details about how to charge batteries, see
for a Single Battery.
If batteries have been stored for longer than allowed, promptly report the
event to the person in charge.
Ensure that batteries are delivered based on the "first in, first out" rule.
Handle batteries with caution to avoid damage.
At 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 for every 10°C increase in temperature.
When the fire suppression equipment is stored as spare parts, the ambient
temperature shall range from 0°C to 50°C and the humidity shall be less than
or equal to 95% RH.
Do not remove the packaging. Check the packaging regularly (recommended:
once every three months). Replace any packing materials that become
damaged during storage. If the Smart Rack Controller is unpacked but will not
be used immediately, put it back to the original packaging with the desiccant,
and seal with tape.
Storage temperature: –40°C to +70°C; relative humidity: 5%–95% RH
Stack Smart Rack Controllers with caution to prevent them from falling over,
resulting in personal injury or equipment damage.
Do not store batteries for extended periods.
