Fire Alarm & Fire Sprinkler Design
Fire Detection and Suppression System Design
EB Life Safety provides fire alarm and fire sprinkler design services for new construction projects per NFPA 72 and NFPA 13.
Design Deliverable Review
The deliverable should identify design assumptions, required contractor submissions, interface owners, testing responsibilities, and information still requiring confirmation by the AHJ or project team. A revision register can connect the narrative, plans, specifications, calculations, and cause-and-effect matrix. It should also identify which items are outside the design scope.
Design Basis and Water Supply
Fire sprinkler criteria should reflect occupancy, commodity or storage arrangement, construction, ceiling geometry, water supply, and the adopted NFPA 13 edition. EB Life Safety can establish hazard classifications, density and area assumptions, standpipe interfaces, fire department connections, and fire pump needs under the applicable NFPA 14 and NFPA 20 provisions. Final delegated design and installation remain subject to the approved scope and AHJ review.
Alarm, Detection, and Notification
Fire alarm design considers initiating devices, notification, emergency voice communication, monitoring, survivability, and interfaces required by the adopted NFPA 72 edition and project code basis. Drawings or performance criteria can document elevator recall, HVAC shutdown, smoke control, emergency power, and other cause-and-effect relationships. Device selection and spacing depend on the occupancy, geometry, environmental conditions, and AHJ requirements.
Coordination Through Submittal
A coordinated package aligns the narrative, specifications, riser information, architectural reflected plans, mechanical controls, electrical power, and contractor submittals. EB Life Safety can review shop drawings, hydraulic calculations, battery calculations, and cause-and-effect matrices against the design intent. The review identifies conflicts; it does not transfer the contractor's licensed design or installation responsibilities.
Design Decisions That Need Early Coordination
Water supply information should be obtained early enough to test whether the planned sprinkler and standpipe demand can be met. A flow test is a snapshot with stated limitations, and elevation, supply reliability, backflow equipment, suction conditions, and future changes can affect the final design. Alarm design likewise depends on room layouts, ceiling features, acoustics, fire-resistance strategy, emergency voice requirements, monitoring, and interfaces with elevators, doors, HVAC, smoke control, and emergency power. The cause-and-effect matrix should be developed with the mechanical, electrical, controls, elevator, and architectural teams rather than added after each trade has completed its drawings. Special hazards, storage arrangements, combustible materials, residential features, and phased occupancy can change the applicable criteria. EB Life Safety can document assumptions and open decisions so the owner and design team know what must be confirmed by the AHJ or contractor. During submittal review, the reviewer should compare equipment listings, hydraulic calculations, voltage-drop and battery calculations, sequence documents, and installation details to the approved basis. A product substitution is not automatically equivalent simply because it has a similar name or capacity; listing limitations and compatibility need to be checked. The final package should identify testing responsibilities, access requirements, maintenance information, and records needed for acceptance. Early coordination does not eliminate contractor design or field changes, but it makes those changes visible before they affect permits, ceilings, shafts, equipment rooms, or occupancy. It is helpful to identify decisions that cannot be made until a survey, water test, equipment selection, or AHJ meeting occurs. Recording that dependency is more useful than assigning a false final answer. The design team can then protect the affected space, reserve pathways, and coordinate a revision when the missing information arrives.

Frequently Asked Questions
Which standards commonly apply?
Projects may involve NFPA 13, 14, 20, and 72 together with the adopted Florida Building Code, local amendments, and AHJ requirements. The project determines the applicable editions.
Do you design or review delegated shop drawings?
The scope can include design criteria, performance specifications, and review of delegated shop drawings and calculations. Responsibility for the delegated design remains with the qualified contractor or designer.
Why is cause-and-effect coordination important?
It documents how detection and alarm events operate connected systems, allowing the design team and AHJ to evaluate sequences involving notification, elevators, HVAC, smoke control, and power.
