Fire & life safety, engineered around your facility
A fire alarm system is only as reliable as the thinking behind it. Device counts and panel sizes come last. First come the building's layout and construction, how it is occupied, which codes the jurisdiction has adopted, what the existing system can support, and what the fire official will expect at acceptance testing.
ISTFIRE works as the technical partner on that thinking, from the first survey through every inspection that follows. Owners, engineers, general contractors and electrical contractors bring us in to design systems, supply and program equipment, commission and test, and keep systems in service for the life of the building.
- Building layout and construction
- Occupancy classification and use
- Adopted codes and local amendments
- Existing system, wiring and devices
- AHJ and fire official requirements
- Manufacturer listings and instructions
- Interfaces with sprinklers, HVAC and elevators
- Inspection and testing obligations
Services across the full system lifecycle
One team for design, installation, testing and ongoing service, so nothing is lost between the contractor who built the system and the one who maintains it.
Fire alarm engineering & design
System design based on building characteristics, occupancy, applicable codes and project requirements.
Engineering & designInstallation & integration
Installation, programming and integration of fire alarm and life safety systems with the building's other systems.
InstallationInspection & testing
Inspection and testing that verifies system performance and documents deficiencies in a written report.
Inspection & testingPreventive maintenance
Scheduled maintenance that reduces system failures, nuisance alarms and unplanned downtime.
MaintenanceRepairs & troubleshooting
Diagnosis and repair of system troubles, failed or damaged equipment and documented deficiencies.
RepairsUpgrades & modernization
Replacement of aging and obsolete equipment, planned to keep the building protected during the work.
UpgradesVoice evacuation & emergency communication
Systems that give occupants clear, intelligible instructions during an emergency.
Voice evacuationLinear heat detection
Continuous heat detection for spaces where spot-type detectors are impractical or unsuitable.
Linear heatConsulting & code compliance
Technical assessments, violation correction plans and recommendations for meeting code and AHJ requirements.
ConsultingHow we work
Five stages, one accountable team. Customers can bring us in at any stage, but the system performs best when the people who designed it also test and maintain it.
Assess
Survey the facility, existing system, drawings and any open violations to understand requirements and risks.
Engineer
Develop the device layout, circuit design, sequence of operations and equipment selection.
Install
Supply, install and program the equipment, directly or alongside your electrical contractor.
Test & commission
Verify every device and function, then support acceptance testing with the AHJ.
Maintain
Keep the system in service with scheduled inspection, testing, maintenance and repair.
Maintenance findings feed back into assessment, so upgrades are planned before equipment fails.
Designed around applicable codes & standards
These are the documents that most often govern fire alarm work in the jurisdictions we serve. Which ones apply to a given building, and in which editions, is determined project by project.
| Reference | Title | What it governs |
|---|---|---|
| NFPA 72 | National Fire Alarm and Signaling Code | Design, installation, inspection, testing and maintenance of fire alarm and emergency communication systems. |
| NFPA 70 | National Electrical Code | Wiring methods and power supply for fire alarm circuits, principally Article 760. |
| NFPA 70E | Electrical Safety in the Workplace | Safe work practices for technicians working on or near energized equipment. |
| NFPA 101 | Life Safety Code | Where alarm, detection and occupant notification are required, based on occupancy. |
| IBC / IFC | International Building and Fire Codes | Adopted, usually with amendments, as the basis for many state and local building and fire codes. |
| State & local | Adopted codes and amendments | For example, the New Jersey Uniform Construction Code and Uniform Fire Code, and the New York City Building and Fire Codes. |
| AHJ | Authority having jurisdiction | The fire official or building department that interprets the code, reviews plans and witnesses acceptance tests. |
| Listings | Manufacturer installation instructions | Equipment listings, device compatibility and programming requirements. |
Requirements vary. The codes that apply to your system depend on your jurisdiction and its adopted editions, the building's occupancy and construction, the scope of work, and the AHJ's interpretation. We identify the applicable requirements for each project rather than assuming one standard fits every building.

Frequently asked questions
Short answers to the questions facility teams ask most. Code references and checklists
What type of fire alarm system does my facility need?
It depends on the building's occupancy, size, construction, whether it is sprinklered, and the codes your jurisdiction has adopted. Some buildings need manual pull stations and notification only; others require automatic detection, voice evacuation or emergency communication. A site survey and code analysis determine what's required, and new systems typically need design documents approved by the AHJ before installation.
How often should a fire alarm system be inspected?
NFPA 72 sets inspection and testing frequencies by component. Many items are tested annually, and some require more frequent inspection. The edition of NFPA 72 your jurisdiction has adopted, its fire code and your fire official determine the exact schedule, so we build inspection plans around your AHJ's requirements.
Why is professional fire alarm testing important?
Testing confirms that every device, circuit and output works, finds problems before an emergency does, and produces the records that fire officials and insurers often ask to see. Qualified testers also know the local requirements that apply to your building.
Can ISTFIRE inspect an existing system?
Yes. We inspect and test existing systems, document any deficiencies, and provide a written report with recommended corrections.
Can ISTFIRE repair systems installed by another contractor?
Yes. We service systems from many manufacturers, not only those we installed. Some proprietary panels require manufacturer software or dealer access for programming changes; if that affects your scope, we'll tell you before work begins.
Can ISTFIRE upgrade an older fire alarm system?
Yes. Options range from replacing the control panel while reusing compatible wiring and devices, to full replacement. Work is usually phased so the building stays protected, with impairment procedures coordinated with the fire official where required.
What information is required to request a quote?
The facility address and building type, the scope of work, the existing panel make and model if known, and any floor plans, specifications, inspection reports or violation notices. The more you can share, the more precise the quote.
What codes apply to my fire alarm system?
Commonly NFPA 72, NFPA 70 and NFPA 101, along with building and fire codes based on the IBC and IFC as adopted and amended by your state and municipality. The applicable editions and local amendments vary by jurisdiction, and the AHJ has final say on interpretation. Codes & standards
Does ISTFIRE provide ongoing maintenance?
Yes. We offer scheduled inspection, testing and maintenance agreements, plus repair service, so one team keeps the full service history of your system.
