What the code requires — 2–4 sentences

When you submit a sample for investigation under the California Referenced Standards Code you must furnish a copy of the operating and installation instructions and any related drawings or wiring diagrams to be used as a guide in the examination and test. The State requires these documents even if they are not in final printed form. This requirement is set out in § 12-72-101(a) and the specific detector/instructions requirement in § 12-72-302(b).

The single most important rule: always include with the sample the operating/installation instructions and any schematic wiring or installation drawings (drafts or manuals are acceptable) so evaluators can install, test, and judge safe operation.

Key defined terms (first mention)

  • Operating and installation instructions — the manufacturer’s directions for installation, safe operation, testing and maintenance (including wiring/schematics where applicable). § 12-72-302(b)
  • Sample submitted for investigation — the physical unit(s) delivered for testing; the accompanying instructions are used to guide examination and test. § 12-72-101(a)

Requirements in detail

What must be furnished with the sample

  • A copy of the operating and installation instructions for the product under test. The copy may be a draft, manual, technical bulletin or other non-final printed form. § 12-72-302(b)
  • Any related schematic wiring diagrams and installation drawings needed to install and test the unit. § 12-72-302(b)
  • Test reports and supporting materials submitted for listing must include wiring diagrams, operating manuals and photographs as part of the test-report contents. § 12-72-101(a)
  • For fire alarm devices specifically, the device must be supplied with installation, operating and maintenance instructions that include a typical installation layout, description of operation and testing, maintenance procedures, household evacuation guidance, and notice to the local fire authority. § 12-72-204(a)

Use the table below to make decisions about what to include.

Decision-relevant dimension Required content / value Form allowed Purpose (what the examiner uses it for) Code Reference
What documents to send with a sample Operating & installation instructions + related schematic wiring diagrams + installation drawings Drafts, manual, technical bulletin — printed edition not required Guide installation, wiring, setup, operation and test of sample § 12-72-302(b)
Test report content when seeking listing Wiring diagrams, operating manuals, photographs, engineering analysis Formal report to accompany test results Provide evidence and enable review against performance standards § 12-72-101(a)
Fire-alarm device purchaser instructions Typical installation layout; operation, testing & maintenance procedures; evacuation info; local fire authority notice On unit or separate sheet; may be referenced by marking Ensure safe installation, user testing & emergency response § 12-72-204(a)
Required marking information (where applicable) Model, electrical rating, sensitivity setting, mounting position, fuses, etc. — some items may appear on wiring diagram rather than unit Permanently marked on unit or on installation wiring diagram Identify unit ratings and direct users to instructions/diagrams § 12-72-302(b)
Printed copy requirement None — a printed edition is not required for submission Drafts acceptable Speeds investigation — final printed manuals can follow § 12-72-302(b)

What the instructions should include (minimum/typical content)

  • Directions and information the manufacturer deems adequate for attaining proper and safe installation, operation and maintenance. § 12-72-302(b)
  • For devices seeking listing or evaluation, include sensitivity/rating information, electrical ratings, mounting orientation, identification of switches/lights/meters, reference to wiring diagrams, and any special cautions (radioactive material text, pressurized container warnings for gas-operated units, etc.). § 12-72-302(b)
  • For household fire alarm devices, supply a typical layout (recommended locations), testing/maintenance procedures and an evacuation plan; instructions may be on the device, separate sheet, or part of a manual, but must be referenced on the unit if not directly attached. § 12-72-204(a)

Exceptions & special cases

  • The instructions and drawings need not be in final printed form; drafts, technical bulletins or manuals are acceptable for investigation purposes. § 12-72-302(b)
  • Components or previously listed devices installed as part of a larger control unit may not require re-submission of component test reports, but the combined installation/wiring must be shown and the test report must identify listed components (catalog number, listing agency, report number/date). § 12-72-101(a)
  • If a device requires mounting in a definite position or connection to tubing/power lengths to function properly, the instructions and diagrams must make that clear because the sample will be tested in its intended position or with specified tubing lengths. § 12-72-203(a)(2–3)

If a specific additional instruction is required by a particular product standard (for example special servicing instructions for gas-operated alarms), that special text must be supplied (see marking and instructions provisions). § 12-72-204(a)

Common mistakes

  • Sending only the physical sample without any wiring diagrams or installation drawings — reviewers rely on those documents to install and test the unit. § 12-72-302(b)
  • Providing only final printed packaging text but omitting schematic wiring diagrams or installation drawings — wiring diagrams can be on a separate sheet and are required for evaluation. § 12-72-101(a)
  • Assuming a printed manual is required — drafts and technical bulletins are acceptable and often used; however, the content must be adequate for safe installation and testing. § 12-72-302(b)
  • Omitting safety or marking information that is required to appear on the unit or wiring diagram (for example electrical ratings or “Do Not Paint” warnings for thermal devices). § 12-72-302(b)

Worked example — concrete scenario

Scenario: Manufacturer submits a new ceiling-mounted smoke/combustion-products detector for listing.

  1. What to include with the sample:

    • A copy of the operating & installation instructions describing mounting, sensitivity adjustment, and maintenance (draft manual ok). § 12-72-302(b)
    • Schematic wiring diagram showing power input, interconnect circuits and connection points (may be presented as a separate installation wiring diagram). § 12-72-101(a)
    • Photographs of the unit and a wiring block diagram to be included in the test report. § 12-72-101(a)
    • If intended ceiling spacing or sensitivity is relevant, include instructions or data for the spacing allocation (detector sensitivity expressed in spacing limitations) because the device will be oven- or fire-tested for spacing qualification. § 12-72-203(b–c)

  2. Format and practical detail:

    • Provide 1 printed copy of the draft manual and one separate wiring schematic (paper or PDF is acceptable for the lab). No final printed book is required. § 12-72-302(b)
    • Mark the unit with required identification (manufacturer name, model, temperature rating) or reference the installation wiring diagram where that information appears. § 12-72-302(b)

Result: The lab can install the detector in the oven or test room per instructions, connect wiring per the schematic, run oven and fire tests, and include the wiring diagrams and operating manual in the test report required for listing. § 12-72-101(a)

Frequently asked questions

What if my operating manual is still a draft — is that acceptable?

Yes. The CRSC expressly permits non‑final printed forms — drafts, manuals or technical bulletins may be furnished for investigation. § 12-72-302(b)

Do I have to include wiring diagrams with the sample?

Yes. Related schematic wiring diagrams and installation drawings must be furnished with the sample and are used as a guide in examination and testing. § 12-72-302(b)

Must the instructions be physically attached to the unit?

Not necessarily. Instructions may be on the device, on a separate sheet, or part of a manual. If not attached, the unit’s marking must reference where the instructions or wiring diagram are located. § 12-72-204(a)

Will the lab accept electronic copies (PDF)?

The code does not mandate a format; it requires that copies be furnished. Practically, labs commonly accept PDFs, but confirm with the specific testing laboratory. The CRSC allows non-final printed forms. § 12-72-302(b)

If components are already listed, do I still send their manuals?

You should include identification (catalog number, listing agency, report number/date) for listed components in the test report; full component manuals may not need retesting, but the combined wiring and installation must be shown. § 12-72-101(a)
