It's time to change the conversation. Every modern firefighting apparatus contains elements of multiplexed and hardwired electrical systems. Only Pierce engineers systems that are purpose-built to serve the fire industry with features poised to seamlessly evolve with technology. 

No clunky retrofits or complicated third-party software. No troubleshooting your troubleshooting. Utilizing proven military grade hardware and wire harnesses, Pierce® electrical systems give you technology built from the ground up for your department. If you have questions, you speak directly to the people who engineered your system, who just so happen to have lunch with the people who welded your frame rails.

One source. One intuitive, singular system. Available in feature packages that provide your desired level of interface, diagnostics, prognostics, maintenance, navigation and more.

Foundation

Electrical Systems Foundation

 

Pierce's electrical systems are purpose-built to evolve with technology in the fire industry, but it all starts with a reliable, maintainable and configurable foundation comprised of proven military-grade hardware and wire harnesses.

Every Pierce custom chassis comes standard with:

  • Electrical distribution centers located strategically throughout the vehicle.
  • Serviceable electrical components readily accessible.
  • Power/signal protection & control components protected against corrosion, heat, vibration, physical damage and water spray.
  • Distribution centers that contain battery power and ground studs for ease of customer supplied component installation.
  • Wiring run in conduit or loom where exposed; wire raceways built into cab structure.
  • IP67 waterproof connectors specified throughout the chassis.

Component Specification

  • Circuit breakers that conform to SAE standards; harnesses conform to SAE, NFPA, NEC, UL, ASTM and WHMA standards.
  • Wire, relays and solenoids sized to 125% of maximum current.
  • Wire insulation is high temperature crosslink.
  • Wire harnesses that include color, function and number coding; function and circuit number stamped at 2" intervals.

Validation

  • Voluntary third party (UL) auditing for electrical compliance to NFPA 1901.
  • Third party EMI/RFI chamber testing to ensure emissions are suppressed at the component source.
  • R&D cycle testing of new components.

WiFi / Touchscreen
