Level II submittals and layout: shop drawings, device spacing and power

NICET assigns 20–30% of its Fire Alarm Systems Level II exam to submittal preparation and system layout. Its outline covers project information, site survey, technical drawings and power/loading work. The checklist below is our review workflow, not a reproduction of a code documentation list.

Establish the review basis

Identify the jurisdiction, enforced editions, local amendments, project specifications and design scope. Identify who is responsible for design and any required professional signoff through the jurisdiction's actual process. Do not substitute a NICET credential for a jurisdiction's design-authorization requirements.

For NFPA 72 (2022) navigation, use §7.2 for documentation, §7.3 for design information, §7.4 for installation drawings and §7.5 for completion documentation. Consult the actual provisions and local submission instructions. A study checklist cannot establish a complete permit package for every AHJ.

NICET's Level II reference list names NFPA 72 (2022), NFPA 70 (2020) and IBC (2021); the two NFPA titles are available on screen. Those exam references do not establish the editions enforced on a job.

What the AHJ should be able to check

Prepare the package so a reviewer can answer these questions without guessing. Use §§7.3–7.4 as the code navigation points; use the selected manufacturer's instructions for equipment details.

• Does the layout fit the building? Resolve room use, ceiling geometry and obstructions against the proposed device locations. Show the design reasoning through the relevant Chapter 17 and Chapter 18 section references and appliance instructions, rather than inserting a generic spacing table.
• Do the plan and riser agree? Trace device identifiers, circuits, remote supplies, interfaces and circuit terminations across both. Resolve an unexplained branch or differing device count before calculating loads.
• Will the selected equipment work together? Identify exact models and settings, compatibility information, synchronization arrangements and power sources. A catalog sheet for a product family is insufficient if the selected configuration is unclear.
• What happens for each initiating event? Trace an input through the proposed sequence to notification, control interfaces and off-premises reporting. Coordinate elevator, smoke-control, door and other interfaces with the responsible design information. State unresolved responsibilities explicitly.
• Can the power and pathways support the design? Connect the drawing counts to circuit loading, voltage drop and each supply's battery calculation. Identify the pathway class and survivability basis using §§12.3–12.4.
• Can the installation be tested and handed over? Reconcile the intended operation with the acceptance plan, record drawings and turnover information. Use §7.5 and the applicable Chapter 14 sections for that review.

These are review questions, not a claim that every AHJ uses the same checklist. Obtain the actual jurisdiction's requirements before submitting.

Audit three calculations separately

Circuit loading: identify the supplying output and aggregate supply limits. List quantity, appliance setting and current from the exact equipment instructions. System Sensor's L-Series manual ties the selected appliance current and voltage checks to the notification circuit.

Voltage drop: record cable route, one-way lengths, resistance source, minimum available source voltage and the load-placement model. Compare each calculated appliance voltage with its listing, and confirm the cable type on the drawing matches the pathway; our fire alarm cable types guide explains FPL, FPLR and FPLP. The voltage-drop guide demonstrates lumped and point-to-point methods with fictional inputs.

Battery capacity: use a worksheet for each bank with separate battery-powered standby and full alarm currents. Document durations by the enforced-edition section, then document aging, temperature and any additional margin without double-counting. Fire-Lite's manual provides the worksheet structure; reconcile historical defaults with the adopted edition. See the battery guide.

A passing result in one calculation cannot clear the other two. If a model, setting or quantity changes, revisit every affected calculation and drawing.

Work one discrepancy all the way through

In a fictional practice package, a plan shows 12 identical notification appliances, the riser shows 10, and the load worksheet uses 10 × 0.090 = 0.900 A. First resolve the design count. If 12 is the confirmed training count, the corresponding load is 12 × 0.090 = 1.080 A, an increase of 1.080 − 0.900 = 0.180 A. The per-appliance current is invented.

Then update the affected circuit total, aggregate supply check, voltage-drop model and battery alarm load. Record the revision and resolve the drawing discrepancy. Correct multiplication cannot compensate for an unresolved equipment count.
