Which of the following describes a suitable method for maintaining an alarm system during outages?

Utilizing a storage battery is an effective method for maintaining an alarm system during outages because storage batteries provide a reliable and consistent source of backup power. They can easily supply energy to the alarm system when the main power source is unavailable, allowing the system to continue monitoring and alerting in case of emergencies. This ensures that the security measures of the alarm system remain operational during power interruptions, maintaining the safety and security of the premises.

Storage batteries are specifically designed for this purpose and are commonly used in alarm systems, providing several advantages such as automatic recharging when the power is restored and dependable energy output for the duration of the outage.

Other options such as capacitors and solar panels may not offer a practical means of maintaining alarm system functions during outages. Capacitors, while useful for short-term energy storage, typically cannot sustain the power needs of a system for significant periods. Solar panels generally require sunlight to function and may not be practical or effective during a complete power outage or at night. Connecting to an external generator can be a temporary solution, but it often involves more complexity, such as needing fuel and manual operation, which may not be ideal for a standalone alarm system reliant on uninterrupted power.
