## Key facts

| Fact | Value |
| --- | --- |
| Defined in | IFC 2009 (2009 editions transcribed in this corpus) |
| Primary source | IFC 2009 Definitions (model text, not a jurisdiction's adopted text) |
| Chapters using the term | 27 (counted across the codes hosted here) |
| Wording identical across codes | Single code (compare before citing one code's wording under another) |

## Direct answer

Fire alarm is a defined term in the International Fire Code (IFC) 2009, in Definitions. The code's own words are: “The giving, signaling or transmission to any public fire station, or company or to any officer or employee thereof, whether by telephone, spoken word or otherwise, of information to the effect that there is a fire at or near the place” No other I-Code in this corpus defines it, so the IFC 2009 definition is the one to work from. The term is used in 27 chapters of this corpus, most often in Fire Protection Systems (IFC 2009), Fire Protection Systems (IBC 2009), Construction Requirements for Existing Buildings (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

## Fire Alarm: 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 |
| --- | --- | --- |
| Read the definition in the adopted IFC | Definitions | |
| Re-check the requirement that uses it | Fire Protection Systems (IFC 2009) | |
| Re-check the requirement that uses it | Fire Protection Systems (IBC 2009) | |
| Re-check the requirement that uses it | Construction Requirements for Existing Buildings (IFC 2009) | |
| Re-check the requirement that uses it | Special Detailed Requirements Based on Use and Occupancy (IBC 2009) | |
| Local amendment to any of the above | Jurisdiction's amendment list | |

## Frequently asked questions

### What is the code definition of fire alarm?

The International Fire Code (IFC) 2009 defines it in Definitions as: “The giving, signaling or transmission to any public fire station, or company or to any officer or employee thereof, whether by telephone, spoken word or otherwise, of information to the effect that there is a fire at or near the place” 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 alarm?

In this corpus the term is used across 27 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 are the minimum fire alarm requirements for a building?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IFC 2009 states, in Definitions: “The giving, signaling or transmission to any public fire station, or company or to any officer or employee thereof, whether by telephone, spoken word or otherwise, of information to the effect that there is a fire at or near the place” It is defined in IFC 2009. It is not the same as Building, which the IBC 2009 defines separately as “Any structure used or intended for supporting or sheltering any use or occupancy.” 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.
