What is the purpose of the dual sound emitting piezos?

The dual sound emitting piezos are designed to provide alarm sound direction. This means that when an alarm activates, the sounds produced by these piezoelectric devices emit from two different sources or locations, which helps individuals pinpoint where the alarm is originating. This directional sound can be critical in emergency situations, allowing responders or affected individuals to locate hazards more quickly and efficiently. It enhances situational awareness, guiding users towards safety or alerting them to specific locations that require attention. The other options relate to visibility, air quality, and battery status, but do not pertain to the directional capability that the dual sound emitting piezos provide.
