What alert does a detector give for a low battery?

A smoke detector typically emits a chirping sound to indicate a low battery. The standard for this alert is to chirp at regular intervals, and the most common interval for many detectors is once every 15 seconds. This alert serves as a reminder for users to replace the battery to ensure the smoke detector functions properly when needed.

Understanding this alert system is crucial for maintaining safety measures within a home or facility, as a fully functional smoke detector relies on having sufficient battery power. Being aware of the specific timing allows users to differentiate between regular operational sounds and alerts signaling a need for maintenance.
