Strobes provide visual notification for occupants with hearing loss. Voice evacuation speakers deliver specific instructions. NFPA 72 requires both audible and visual notification

Reviewed by a licensed fire protection engineer Quick answer: Heat detectors are used where smoke detectors would produce constant false alarms — kitchens, garages, dusty warehouses, and high-temperature mechanical rooms. Fixed-temperature detectors activate at a preset threshold (typically 135 to 200 degrees Fahrenheit). Rate-of-rise detectors trigger when temperature climbs rapidly. Combination

Reviewed by a licensed fire protection engineer Quick answer: When a fire alarm activates, other building systems must respond automatically. Elevators return to the ground floor. HVAC shuts down to prevent smoke spread. Security doors unlock for evacuation. Stairwell fans pressurize exit paths. NFPA 72 specifies these integration requirements. Annual

Reviewed by a licensed fire protection engineer Quick answer: The fire alarm control panel is the brain of your building's detection and notification system. It receives signals from every detector and pull station, decides whether the condition is a real alarm, activates horns and strobes, triggers elevator recall

Reviewed by a licensed fire protection engineer Quick answer: Commercial smoke detectors are networked, addressable devices engineered for large-area coverage — fundamentally different from residential single-station units. The main types are ionization, photoelectric, dual-sensor, aspirating, and beam detectors. NFPA 72 governs selection, spacing, and placement. Choosing the right detector for each

NFPA 101 Life Safety Code governs every component — exit access, the exit itself, and exit discharge. Non-compliance is a life safety violation

Reviewed by a licensed fire protection professional Fire-rated doors create barriers that slow fire spread and smoke migration between building compartments. NFPA 101 and the IBC require them at stairwells, fire walls, hazardous areas, and occupancy separations. Ratings range from 20 minutes to 3 hours, tested per ASTM E119. Annual

Reviewed by a licensed fire protection professional NFPA 101 Life Safety Code requires illuminated exit signs at every exit in virtually all occupied buildings. Signs must be legible from 50-100 feet, maintain minimum 5 foot-candles of brightness, and have battery backup providing at least 90 minutes of illumination during power

Reviewed by a licensed fire protection professional OSHA 29 CFR 1910.38 requires a written emergency action plan for most commercial and industrial workplaces. The plan must cover evacuation routes, assembly points, personnel responsibilities, and accommodations for people with disabilities. OSHA recommends 2-4 fire drills per year. Unwritten plans fail

Reviewed by a licensed fire protection professional Emergency lighting must activate automatically during power failure, provide minimum 1 foot-candle of illumination on evacuation paths, and sustain at least 90 minutes of battery-powered operation. NFPA 101 Life Safety Code mandates it in virtually all commercial buildings. Monthly 30-second tests and annual

Reviewed by a licensed fire protection professional Every commercial kitchen must have a wet chemical hood suppression system -- NFPA 96 mandates it, no exceptions. These systems spray potassium-based agents that chemically react with hot oil to smother grease fires, while simultaneously cutting gas and electric supply to cooking equipment.
Systems & Installation
Reviewed by a licensed fire protection professional Fire suppression systems use specialized agents -- wet chemical, clean agents (FM-200, Novec 1230), CO2, foam, inert gas, or dry powder -- to extinguish or control fires in spaces where water sprinklers would cause more damage than the fire itself.
