## Key facts

| Fact | Value |
| --- | --- |
| Defined in | IBC 2009, IFC 2009 (2009 editions transcribed in this corpus) |
| Primary source | IBC 2009 Fire Protection Systems (model text, not a jurisdiction's adopted text) |
| Chapters using the term | 18 (counted across the codes hosted here) |
| Wording identical across codes | Yes (compare before citing one code's wording under another) |

## Direct answer

Fire protection system is a defined term in the International Building Code (IBC) 2009, in Fire Protection Systems. The code's own words are: “Approved devices, equipment and systems or combinations of systems used to detect a fire, activate an alarm, extinguish or control a fire, control or manage smoke and products of a fire or any combination thereof.” The IFC 2009 carries the same definition word for word, so the term means the same thing in each. The term is used in 18 chapters of this corpus, most often in Fire Protection Systems (IFC 2009), Fire Protection Systems (IBC 2009), Flammable and Combustible Liquids (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

## What must be verified before using this guidance?

Two of the I-Codes in this corpus define **Fire Protection System**, in identical words.

### The term in use

How the code actually writes about fire protection system, quoted from the 2009 text hosted here:

> The fire code official shall have the authority to require construction documents and calculations for all fire protection systems and to require permits be issued for the installation, rehabilitation or modification of any fire protection system.

— [IFC 2009 §901.2](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/fire-protection-systems.md)

> No person shall remove or modify any fire protection system installed or maintained under the provisions of this code or the International Fire Code without approval by the building official.

— [IBC 2009 §901.3](https://harth.build/resources/building-codes/us-states/maryland/ibc-2009/fire-protection-systems.md)

> Piles of containers or portable tanks shall not be stored closer than 3 feet (914 mm) to the nearest beam, chord, girder or other obstruction, and shall be 3 feet (914 mm) below sprinkler deflectors or discharge orifices of water spray or other overhead fire protection system.

— [IFC 2009 §3404.3.5.3](https://harth.build/resources/building-codes/us-states/rhode-island/ifc-2009/flammable-and-combustible-liquids.md)


## The terms fire protection system is built out of

The definition above leans on 3 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what fire protection system covers:

- **[Equipment](https://harth.build/resources/glossary/equipment.md)** — IRC 2009: All piping, ducts, vents, control devices and other components of systems other than appliances that are permanently installed and integrated to provide control of environmental conditions for buildings.
- **[Approved](https://harth.build/resources/glossary/approved.md)** — IBC 2009: Acceptable to the code official or authority having jurisdiction.
- **[Control](https://harth.build/resources/glossary/control.md)** — IRC 2009: A manual or automatic device designed to regulate the gas, air, water or electrical supply to, or operation of, a mechanical system.

## Fire Protection System: what to open, and in what order

Every row is a document this term depends on. The [ICC code library](https://codes.iccsafe.org/codes) and the [ICC adoption maps](https://www.iccsafe.org/advocacy/code-adoption-maps/) cover the middle rows.

| Check | Where | Confirmed |
| --- | --- | --- |

## Frequently asked questions

### What is the code definition of fire protection system?

The International Building Code (IBC) 2009 defines it in Fire Protection Systems as: “Approved devices, equipment and systems or combinations of systems used to detect a fire, activate an alarm, extinguish or control a fire, control or manage smoke and products of a fire or any combination thereof.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.

### Which parts of the code depend on fire protection system?

In this corpus the term is used across 18 chapters, led by Fire Protection Systems in the IFC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.

### What is a fire protection system?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Fire Protection Systems: “Approved devices, equipment and systems or combinations of systems used to detect a fire, activate an alarm, extinguish or control a fire, control or manage smoke and products of a fire or any combination thereof.” It is defined in IBC 2009, IFC 2009. Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.
