Where are plastic covers installed on pull-boxes to prevent false alarms?

Plastic covers are installed on pull-boxes in high schools and dorms primarily to prevent false alarms. These settings often have a high volume of young individuals, such as students, who may unintentionally activate fire alarms due to curiosity or lack of understanding about their serious implications. By covering the pull-boxes with plastic covers, it adds a layer of protection against accidental pulls, thereby reducing the likelihood of false alarms. This helps maintain a safer environment in educational institutions where the swift response to actual emergencies is critical, and it minimizes unnecessary disruptions to the learning process and false calls to emergency services.

While the other environments listed may also experience false alarms, educational institutions like high schools and dorms are particularly targeted for this preventive measure due to the demographic of the population they serve.
