In New Jersey and New York City, fire alarm systems are required by law for safety reasons, but malfunctions can endanger people and property and result in expensive infractions.
Whether you’re a building owner, property manager, or facilities professional, understanding fire alarm system faults and how to address them is crucial for compliance and safety.
What Is a Fire Alarm System Fault?
A fault fire alarm condition means your system has a problem that could compromise its ability to detect fire or alert building occupants.
A failed inspection, penalties, or—worse yet—death in an actual emergency could follow from this.
