Safety & compliance
Built to NFPA 1123 & 1126
PyroNext hardware and Studio software were designed against NFPA 1123 (Outdoor Fireworks Displays) and NFPA 1126 (Proximate Audience Pyrotechnics) from the ground up — not retrofitted to meet them. Every firing safety requirement below is mapped to specific, confirmed hardware behavior.
This page cites specific NFPA sections for transparency with operators, AHJs, and safety-minded partners. It is a working reference, not a substitute for formal compliance sign-off — always verify current requirements with your local Authority Having Jurisdiction.
Firing safety & arming interlocks
NFPA 1123 §9.2.2 / §9.2.3 · NFPA 1126 §8.3.3
Two independent actions required before firing power reaches an igniter
Connect requires a physical key-operated switch position AND a separate, distinct fire command before any output is energized. These are genuinely independent hardware-and-software actions — not two prompts for the same action.
NFPA 1123 §9.2.4 / §9.2.5
Clear visual indication of armed state
Connect's system status indicator shows a distinct, unique state for armed — visually different from every other system state (idle, scanning, fault, firing). The code permits a light, a beeper, or both; Connect satisfies this with a clear, unambiguous visual indicator.
NFPA 1126 §8.3.4 / §A.8.3.4
Switch position labeling
Each arming switch position is clearly and legibly labeled, satisfying both the general labeling requirement and NFPA 1126's more specific letter/number guidance.
NFPA 1123 §9.2.10
Hardware shunt relays — exceeding code requirements
Blasting-style shunts are not required by code for this class of firing unit. Connect includes them anyway — an independent hardware safety layer beyond what NFPA requires.
Continuity testing
NFPA 1126 §8.3.1.1 / §8.3.1.2
Continuity current well under the 25mA regulatory limit
IQ Slat continuity scanning runs at approximately 20mA — under the 25mA code maximum — and is sourced from a completely separate, isolated power domain from the firing circuit. The continuity supply can never energize a firing output, by hardware design, not just by firmware logic.
Power source isolation
NFPA 1123 §9.2.11 / §9.2.11.2
Isolated power supply for AC-direct operation
When operating on AC mains power, Connect's power path includes a transformer-isolated AC-DC conversion stage rated for high-voltage input-to-output isolation — satisfying the isolation-transformer requirement for commercial-power-fed firing units.
NFPA 1126 §8.3.2.1 – §8.3.2.3
Independently switched on both sides of every firing circuit
Every output channel is independently switched on both the high side (at Connect) and the low side (at the IQ Slat), with both sides defaulting to off on power-up. This satisfies NFPA 1126's dual-switching compliance path directly.
Field wiring practice
NFPA 1126 Annex A wiring guidance
No igniter lead ever permanently wired to a shared bus
Each igniter connection is switched individually and only makes contact with any shared circuit path transiently, at the moment its own dedicated output activates. No igniter lead is ever continuously bussed to shared wiring — satisfying the underlying safety principle of this guidance directly.
Pre-show inspection safety
NFPA 1123 §9.3.1.1 / §9.3.1.2
System cannot be armed or in test mode during inspection
Connect's safe state is defined as the only state where the system is neither armed nor in test mode — there is no possible system state that satisfies “not armed and not in test” other than fully safe. This is a structural property of the system design, not a procedural instruction that depends on correct operator behavior alone.
Studio App — site planning & AHJ documentation
Beyond firing hardware, the Studio App is built to help licensed operators plan, document, and demonstrate NFPA 1123 compliance for every show.
Automatic separation zones
Every firing position automatically displays its required audience and crew separation distances, scaled to shell size from 1" through 12" mortars — no manual lookup tables.
Wind-adjusted fallout visualization
Live and forecast wind data reshapes the fallout zone into an accurate downwind drift pattern in real time.
Automatic property boundary detection
Site boundaries are auto-detected from parcel data — no manual tracing required to lay out a compliant site plan.
Compliance distance checks
Any audience area, exclusion zone, or property line is automatically checked against the required NFPA distance, with a clear pass/fail label and exact clearance margin.
AHJ-ready documentation export
One-click export of a compliance PDF containing the site map, separation distance table, and weather conditions — ready to hand to an Authority Having Jurisdiction.
Shareable site plans
A live read-only link can be sent directly to an AHJ or fire marshal for review — no account or app access required on their end.
On the compliance roadmap
Based on a full review of NFPA 1123 and 1126, additional capabilities are planned for Studio:
- Expanded separation-distance engine — angled mortars, comets and mines, elevated firing positions, and proximity to sensitive facilities
- Special-venue calculators — floating/barge displays and rooftop or limited-egress venues
- Automated pre-show compliance check — flags any separation shortfall or high-wind condition before a show is finalized
- Permit application package builder — auto-generated permit paperwork matching what most AHJs require
- Actionable weather-suspension workflow — one-click options when a weather threshold is exceeded
- Multi-jurisdiction approval tracking — for water-based, near-airport, or road-closure displays
- Post-display inspection checklist — structured fallout-area inspection workflow
This page reflects PyroNext's compliance design work as of July 2026. Always verify current requirements against the applicable NFPA standard and your local Authority Having Jurisdiction — PyroNext hardware and Studio are planning and execution tools and do not replace professional judgment or AHJ approval.
