Fire Protection Terms & Glossary
Fire protection language can get technical fast. This glossary is built to make common sprinkler, fire alarm, extinguisher, suppression, monitoring, deficiency, and compliance terms easier to understand for property owners, managers, contractors, and team members.
Definitions on this page are simplified for education and general understanding. Actual code obligations, testing requirements, repair decisions, and system conditions can vary by occupancy, system design, authority having jurisdiction, manufacturer instructions, and what is found in the field.

If you are dealing with a failed inspection, open deficiencies, alarm trouble, sprinkler issues, overdue service, suppression system concerns, extinguisher service needs, monitoring questions, or backflow-related fire protection support, EXO Fire Protection can help you move from uncertainty to a clearer next step.
