Storage batteries should be placed to ensure that equipment, including overcurrent devices, is not adversely affected by what?

When dealing with storage batteries in a fire alarm system or other electrical systems, it is crucial to consider the impact of battery gases. Batteries, especially lead-acid types, can release gases such as hydrogen during charging or discharging processes. These gases can create hazardous conditions, including risks of explosion or corrosion of surrounding equipment.

If batteries are not properly ventilated or are placed too close to sensitive equipment, the accumulation of these gases can adversely affect the operation of overcurrent devices and other components in the circuit, potentially leading to failures or unsafe conditions. Ensuring that batteries are located in an area where the release of gases can disperse safely helps maintain the overall system's integrity and safety.

The focus on battery gases is vital in installation and maintenance guidelines, as proper placement can significantly enhance safety and prevent equipment damage. Other concerns like battery fluids, electrical shorts, or heavy vibrations, while important, do not have the same direct and immediate impact on the operational stability of overcurrent devices as the risks posed by battery gases.
