Final answer:
The duration for which backed up, protected, independent power must be provided for IDS systems depends on various factors and requirements. High-security facilities may require backup power for several hours or days, while smaller installations may only need a few hours of backup power. Examples include mission-critical server rooms in financial institutions and residential home security systems.
Step-by-step explanation:
The duration for which backed up, protected, independent power must be provided for IDS systems depends on various factors and requirements. The specific time period can vary depending on the criticality of the system and the potential consequences of power loss. For high-security facilities, such as data centers or military installations, the power backup may need to last for several hours or even days to ensure continuous operation and protection. However, for smaller installations or non-critical systems, a backup duration of a few hours may be sufficient.
One example of a system that requires a longer backup duration is a mission-critical server room in a financial institution. These systems need to be operational at all times to ensure uninterrupted transaction processing. In such cases, the backup power supply is usually provided by uninterruptible power supply (UPS) systems that are capable of providing power for several hours or more. These UPS systems are often supported by backup diesel generators that can take over in case of extended power outages.
In contrast, a residential home security system may only need backup power for a few hours to keep it operational during short outages. These systems can be powered by battery backup units or smaller UPS systems that are designed for residential use.
