What is the minimum standby time for operation of an alarm system on secondary power in a household?

The minimum standby time for the operation of an alarm system on secondary power in a household is 24 hours. This standard is in place to ensure that alarm systems can remain functional during power outages or when the primary power source fails.

Having a 24-hour backup duration ensures that the system can effectively protect the household during a reasonable period of disruption. This timeframe considers the likelihood of short-term power failures while providing enough coverage in case of extended outages. By maintaining this standard, systems are better equipped to enhance safety and security for homeowners, allowing sufficient time for utility restoration or alternative measures to be established.

In contrast, shorter standby time options would not provide adequate assurance that the alarm system would remain operational during power interruptions.
