Technical Documents, Drawings, and Submittals (NFPA 72-2022 Ch. 7)
NFPA 72-2022 Ch. 7 · NFPA 72-2022 §14.6 · NFPA 72-2022 §10.3 · NEC 2020 Ch. 9, Table 8 · Ugly's Electrical References 2020 · CSI MasterFormat · Outline tasks 1.3.1, 1.2.1, 1.1.1
What NICET expects from a Level I technician
Task 1.3.1 Knowledge of technical documents belongs to domain 1.3 (Submittal Preparation and System Layout), which is worth 1 to 11 percent of the exam (roughly 1 to 9 of the 85 questions). Level I candidates are not asked to design: you are expected to recognize, read, and use the project documents (shop drawings, riser, wiring diagrams, data sheets, sequence of operation, completion and inspection records) and to know what Chapter 7 of NFPA 72-2022 requires. These documents also show up inside installation (1.1.1) and testing (1.2.1) questions: where the candela is shown, where the EOL goes, which form is filled out, and how long records are kept.

Completion, software, and the documentation cabinet
- Delivery to the owner (7.5.3.1): owner's manual and manufacturer's instructions, record drawings, record of completion, and, for software-based systems, a copy of the site-specific software. Delivered upon final acceptance (7.5.3.2).
- Record drawings (7.5.5): shop drawings updated to reflect the actual installation, with the sequence of operation per the actual programming; a copy goes in the documentation cabinet. Field redlines are their basis.
- Record of completion (7.5.6): completed by the installing contractor and submitted to the AHJ and the owner at the end of the job; with several contractors, each fills in its portion (7.5.6.2). Modifications go on a revised, dated version that supplements the original (7.5.6.6). An electronic file with AHJ approval must be readable with standard software and backed up (7.5.6.7).
- Site-specific software (7.5.7): copy to the owner; user passcode and programming password (or instructions for obtaining it from the manufacturer); an on-site copy in nonvolatile, nonerasable, nonrewritable memory.
- Cabinet (7.7.2): provided with every new system, at the control unit or another approved location (identified at the control unit); large enough; labeled SYSTEM RECORD DOCUMENTS; no documentation inside the FACU (7.7.2.3).
- Security (7.7.3): if documents cannot be protected from public access, sensitive information may be removed as long as the owner keeps a complete set accessible to the AHJ.
Forms (7.8.2) and record retention
| Figure | Form |
|---|---|
| 7.8.2(a) | System Record of Completion |
| 7.8.2(b)–(f) | Completion supplements: ECS, power systems, NAC power extender panels, interconnected systems, code deviations |
| 7.8.2(g) | System Record of Inspection and Testing |
| 7.8.2(h)–(l) | ITM supplements: notification appliances, initiating devices, MNS, ECS, interface components |
| 7.8.2(m) | Single- and multiple-station alarms and household systems |
| Record | Retention | Section |
|---|---|---|
| Inspection, testing, and maintenance | Until the next test + 1 year | 14.6.2.1 |
| Permanent (record drawings, O&M manuals, sequence of operation) | Life of the system, kept by the owner | 14.6.1.3 |
| Medium | Must last the whole retention period; paper or electronic | 14.6.2.3 |
Reading drawings
Formula: actual distance = measurement on the drawing (in.) × feet per inch.
| Scale | 1 in. on the drawing = | Example |
|---|---|---|
| 1/8 in. = 1 ft-0 in. | 8 ft | 3-3/4 in. → 30 ft |
| 3/16 in. = 1 ft-0 in. | 5.33 ft | 3 in. → 16 ft |
| 1/4 in. = 1 ft-0 in. | 4 ft | 7-1/2 in. → 30 ft |
| 1/2 in. = 1 ft-0 in. | 2 ft | 2-1/2 in. → 5 ft |
| 1 in. = 20 ft (engineering) | 20 ft | 1-1/2 in. → 30 ft |
- Graphic scale: if a drawing is printed reduced (half size), the written scale no longer applies; the graphic bar shrinks with the drawing and stays correct.
- Legend and symbols: NFPA 170 defines the symbols; generally a basic shape is used with letters or subscripts showing the type, plus notes next to the symbol (candela, address, circuit). Conventions vary: always confirm in the legend.
- Common annotations: AFF (above finished floor), cd (candela), EOL, SLC/IDC/NAC, TYP (typical), NIC (not in contract), address tags such as L2-045 (loop 2, address 45).
- Reflected ceiling plan (RCP): shows the ceiling as if reflected onto the floor: lights, diffusers, heights, and beams. Useful for coordinating detectors.
- Data sheets (cut sheets): standby and alarm current, voltage range, candela vs. current table, listing, compatibility, and installation instructions. Devices powered by an IDC or SLC must be listed for use with that control unit (10.3.3).
Construction documents
- Specifications: CSI MasterFormat, Division 28 Electronic Safety and Security; in recent editions the section is 28 46 00 Fire Detection and Alarm (formerly 28 31 00). Div. 21 = fire suppression; Div. 26 = electrical.
- Submittal: data sheets, shop drawings, and calculations sent for engineer review and AHJ plan review/permit before installation.
- RFI: a formal question to the designer about conflicts or omissions. Change order: authorizes changes in scope, cost, or schedule. Punch list: items to correct before acceptance.
Ugly's / NEC Ch. 9, Table 8 (uncoated copper)
| AWG | cmil | Ω/kft solid | Ω/kft stranded |
|---|---|---|---|
| 18 | 1620 | 7.77 | 7.95 |
| 16 | 2580 | 4.89 | 4.99 |
| 14 | 4110 | 3.07 | 3.14 |
| 12 | 6530 | 1.93 | 1.98 |
R = (total conductor length ÷ 1000) × Ω/kft; in a 2-wire circuit the conductor length is twice the run length. VD = I × R.
Common traps:
- The sequence of operation may be a matrix or a narrative; both comply.
- Shop drawings ≠ record drawings: record drawings reflect what was actually installed.
- Documentation is not stored inside the FACU; it goes in the cabinet labeled SYSTEM RECORD DOCUMENTS.
- 7.8.2(a)–(f) = completion; 7.8.2(g)–(l) = inspection and testing; 7.8.2(m) = household/single-station.
- ITM records: next test + 1 year; permanent records: life of the system.
- NFPA 72 does not set a drawing scale; it requires an indicated scale and a graphic scale.
- When there is a field conflict (diffuser, beam, duct, new partition), a Level I technician does not redesign: report it and request an RFI.
Finding it fast in the printed code book: Chapter 7 is short, so one permanent tab at its first page plus tabs at 7.2.1 (minimum documentation list), 7.4 (shop drawings), 7.5.6 (record of completion), and the 7.8.2 forms will cover most questions. Every 7.x section is in Chapter 7; the 14.6 record-retention rules are at the end of Chapter 14. In the index at the back of NFPA 72, look up "Documentation", "Shop drawings", "Record drawings", "Record of completion", "Site-specific software", "Records", and "Forms". Highlight "SYSTEM RECORD DOCUMENTS", "1 year thereafter" (14.6.2.1), and "life of the system" (14.6.1.3). The typical input/output matrix is Figure A.14.6.1.1 in Annex A (an asterisk next to a section number means annex material exists). For NEC Chapter 9, Table 8 (Conductor Properties), tab the page near the back of the NEC or use the conductor table in Ugly's table of contents.
