No matter which type of business you own or manage, your commercial fire alarm systems must be inspected, tested, and maintained by a fire protection company in accordance with the National Fire Protection Association Standards – NFPA 72, Chapter 14. Though inspection requirement intervals may vary depending on your fire alarm equipment and the rules imposed by your local Authorities Having Jurisdiction (AHJ), the NFPA Standards for quarterly, semi-annual, and annual fire alarm inspection are universal.

Fire Alarm Inspection Requirements

The following is a general commercial fire alarm inspection guide to help you and your staff with recommended and required equipment inspections and testing.

How often each fire alarm system and its components need to be visually inspected and functionally tested is dependent on the types of systems in your warehouses, distribution centers, retail stores, grocery stores, big box stores, restaurants, and other multi-site facilities.

Commercial alarm systems include a wide range of life safety solutions engineered to detect and alert occupants to many different life-threatening and property-damaging hazards in addition to fire – carbon monoxide poisoning, leaky pipes, severe weather, and active shooters, for example.

Thorough visual inspections and physical testing of the components of your fire alarm system must occur weekly, monthly, quarterly, semi-annually, annually, every five and 10 years, according to the NFPA Standards and your AHJ rules. Semi-annual, annual, five-year, and 10-year fire alarm inspections must be performed by licensed fire protection technicians.

Something as simple as checking and replacing smoke detector batteries – even if they’re hard wired – can reduce the 25% of smoke detector failures that occur annually. – NFPA

Let’s Not Forget Fire Alarm Inspection Verification & Documentation

When you work with AIE, post-inspection and testing recommendations are analyzed and categorized as to the level of action needed. A database is generated for all fire alarm system problems (and other fire protection equipment), which assists with verification of inspections and testing, future solutions, cost reductions, budgeting, and priorities.

Using digital inspection forms and electronic document management meets NFPA, AHJ, and OSHA requirements. Electronic records also provide a greener approach and create easy internal access to the information, as well as for any fire-safety code authority who requests it.
