How are fire alarms in high-rise buildings typically programmed to notify occupants?

In high-rise buildings, fire alarms are typically programmed to notify occupants by sounding alarms on the designated alarm floor, as well as on the floors immediately above and below this level. This strategy serves several important purposes.

First, it provides clear guidance to occupants about where the fire is located, allowing them to make informed decisions about their escape routes. By sounding alarms on adjacent floors, the system alerts residents to the potential danger and encourages them to evacuate the building before smoke or fire spreads to their area.

Additionally, this approach helps manage the overall alarm response. If alarms sounded on all floors, it could create confusion and panic, overwhelming both occupants and emergency responders. Instead, the focused alarm strategy helps streamline evacuation efforts and coordination for first responders by limiting the areas that require immediate attention.

This method enhances safety in the building by balancing the need to notify residents while avoiding unnecessary disturbances for those who are not in immediate danger.
