Fire Alarm & Life-Safety Systems

Life-safety systems are the ones a building can't open without. We install, integrate, and coordinate them to code and carry them all the way through final inspection sign-off.

What We Provide

Life-Safety Systems — in detail

We design, install, terminate, and commission life-safety systems for commercial and industrial facilities across Arizona — coordinated with our own underground, HVAC, and construction crews. Here is what the life-safety scope includes — and what it takes to carry it through AHJ sign-off.

Fire Alarm Systems

  • Rough-in, devices, and wiring — We rough-in and wire the fire-alarm system — the conduit, back-boxes, and cabling that connect every smoke detector, pull station, and notification device back to the panel.
  • Panels and coordination — We install the fire-alarm control panels and coordinate the system with the fire-protection engineer and the authority having jurisdiction so it matches the approved design.
  • Notification appliances — Horns, strobes, and speakers alert occupants to evacuate. We install notification appliances laid out for the audibility and visibility the code requires throughout the building.
  • Integration with sprinkler, elevator, and HVAC — Fire alarm does not work alone — it monitors sprinkler flow, recalls elevators, and shuts down HVAC on an alarm. We wire and coordinate those interlocks so the building responds as a system.

Emergency & Standby Power

  • Emergency egress circuits — The circuits that keep egress lighting and life-safety equipment energized during an outage. We install them per NEC Article 700, kept independent of the building's normal power.
  • Generator and ATS coordination — We coordinate the emergency loads with the generator and automatic transfer switch so life-safety systems pick up power within the time the code allows.
  • Legally-required standby systems — Some systems — smoke control, certain pumps — are legally-required standby under NEC Article 701. We install and separate these systems exactly as the code requires.
  • Battery and inverter systems — Where a generator is not required, battery and inverter (UPS) systems carry emergency lighting and critical loads through an outage. We install and wire them and verify the runtime.

Exit & Emergency Lighting

  • Exit signs and egress lighting — Illuminated exit signs and egress lighting guide occupants out in an emergency. We install them along the entire path of egress as the code requires.
  • Photometric egress compliance — Egress lighting has to deliver minimum light levels along the exit path. We install to the photometric design that proves the path stays lit when normal power is lost.
  • Testing and maintenance — Emergency lighting must be tested on a schedule. We commission the systems at turnover and can set up the recurring testing that keeps them compliant.
  • Self-diagnostic fixtures — Self-testing emergency fixtures check themselves and flag failures, cutting manual testing labor. We install these where they are specified.

Mass Notification & Sign-Off

  • Mass-notification interfaces — Mass-notification systems broadcast emergency messages beyond the fire alarm. We install the interfaces and pathways that tie them into the building's systems.
  • Testing and acceptance — Before a building can open, the life-safety systems are tested and accepted. We perform and support the acceptance testing with the AHJ and the fire marshal.
  • Authority-having-jurisdiction (AHJ) sign-off — Nothing opens without the AHJ's sign-off. We carry the life-safety systems through inspection and the final sign-off that allows the building to be occupied.
  • Documentation and owner training — We hand over the record documents and train the owner's staff on the systems they will operate and maintain.

Where It Applies

Markets we serve

From our base in Tucson, life-safety work takes us into offices, schools, and industrial buildings — anywhere an AHJ expects the system tested and signed off.

  • Commercial and office
  • Healthcare
  • Schools and universities

The Design-Build Advantage

Designed, self-performed, and accountable

Life-safety is the system the fire marshal walks last. Because we install the fire alarm circuits, the egress lighting, and the standby power behind them, one contractor stands at the acceptance test — us.

  • Installed to the NEC and NFPA and coordinated with the fire-protection scope
  • Carried through testing and AHJ acceptance, not just rough-in
  • Coordinated with our engineering for egress and emergency power
  • One accountable team for the systems that gate occupancy

FAQ

Life-safety questions, answered

Have an NEC or fire-code question of your own? Ask our free code assistant — it is trained on the same NEC and fire-code material our field crews work to.

What counts as a life-safety electrical system?

The systems a building cannot legally open or operate without: fire alarm and mass notification, exit signs and egress lighting, and the NEC Article 700 emergency and Article 701 legally required standby power behind them — plus the interlocks that recall elevators and shut down HVAC on an alarm.

Do you install commercial fire alarm systems?

Yes. We rough-in and wire the system, set the panels and notification appliances, and coordinate with the fire-protection engineer and the AHJ so the installed system matches the approved NFPA 72 design — then we stand at the acceptance test until it passes.

What is the difference between emergency and standby power?

The NEC splits it three ways. Article 700 emergency systems — egress lighting, fire alarm — must pick up load within seconds and stay fully separate from normal power. Article 701 legally required standby covers systems like smoke control. Article 702 optional standby is everything the owner simply wants to keep running. Each has its own wiring and separation rules, and we install all three — along with the generators and transfer switches behind them.

How often does emergency lighting have to be tested?

Fire codes based on NFPA 101 call for a brief monthly functional test and a full 90-minute annual test of emergency and egress lighting, with records kept. We commission the systems at turnover and can set up the recurring testing that keeps a facility compliant.

Who inspects and signs off life-safety systems in Tucson?

The authority having jurisdiction — within city limits that means Tucson Fire Department review and acceptance testing alongside City of Tucson building inspections, with Pima County and the local fire districts handling unincorporated areas. We schedule the inspections, run the acceptance tests, and carry the systems through the sign-off that gates occupancy.

Do healthcare facilities have extra life-safety requirements?

Yes. Hospitals and many clinics fall under NEC Article 517, which layers an essential electrical system — separate life-safety, critical, and equipment branches — on top of the usual requirements. We build to those requirements on healthcare and institutional projects.
