Plan Review, Documentation, and Acceptance Testing
The documentation package
A submittal for plan review typically includes: shop drawings (floor plans, riser diagram, device locations, wiring), calculations (battery, voltage drop, audibility/candela), manufacturer data sheets, sequence of operations, record of completion, and qualifications of the designer. The AHJ reviews for code compliance and may require revisions before approval.
Acceptance testing
Acceptance testing verifies the installed system against the approved plans and NFPA 72. It includes functional testing of every initiating device, notification appliance, and control function; battery test; supervision tests (open, ground, short); alarm and trouble annunciation; voice intelligibility where applicable; and interface testing with suppression, HVAC, elevators, and access control. The record of completion is signed by the installer and the AHJ representative.
Documentation traps
- Submitting a riser diagram without a sequence of operations.
- Omitting voltage-drop calculations for NACs, leading to underperforming appliances.
- Forgetting that the record of completion must be signed and retained.
- Assuming acceptance testing is optional when the AHJ requires it - it is mandatory.
- Missing that as-built drawings must reflect field changes.
Worked example
A plan shows 24 horns on one NAC rated 2.0 A; the panel NAC is rated 2.5 A. Voltage-drop calculation shows the last device receives insufficient voltage. The reviewer requires splitting the circuit or adding a booster supply. This is the classic plan-review catch: nameplate current is not the same as delivered voltage.
Rule of thumb
If it is not documented, it was not done. Every design decision (spacing, battery, voltage drop, sequence) must appear in the submittal, and every function must be demonstrated at acceptance.
