Where must an audio/visual fire signal device be located?

The requirement for an audio/visual fire signal device to be located in each restroom, hallway, lobby, and general assembly area is based on safety regulations designed to ensure that all occupants can be alerted to a fire emergency effectively. These devices are crucial for providing audible alerts to individuals who may be hearing impaired, as well as visual signals for those who may have difficulties hearing alarms.

Restrooms, hallways, lobbies, and assembly areas represent critical points where people are likely to be present and where they need immediate notification in the event of a fire. Having devices in these locations ensures that alerts can be heard or seen regardless of where individuals are within the building, thus maximizing safety and response time.

The other choices do not meet the comprehensive safety requirements typically mandated by fire safety codes. Only placing devices in hallways and lobbies would fail to alert those in restrooms or assembly areas, while positioning them only at the main entrance or in storage rooms would leave significant gaps in coverage, potentially endangering lives during an emergency. This comprehensive approach to placement ensures that all areas occupied by people receive adequate warning in a timely manner.
