In what configuration should batteries be attached to the panel in an alarm system?

In an alarm system, batteries should be attached to the panel in a parallel configuration. This setup allows each battery to provide its voltage without affecting the others, ensuring that the system receives a consistent power supply. When batteries are connected in parallel, their capacity increases, which means they can provide power for a longer duration if the primary power source fails. Additionally, if one battery were to fail, the others can still maintain power to the alarm system, enhancing reliability.

In contrast to this, a series configuration would increase the voltage, but it could create issues if one battery fails, as the entire system would lose power. A combination configuration can complicate the design unnecessarily, while a grid configuration is typically not relevant in this context. The parallel setup helps to maximize safety and efficiency in alarm system operations.
