NEMSIS Installation and Implementation Guide

The NEMSIS Installation and Implementation Guide is designed to help you configure your department's Firehouse® database to use the National EMS Information System (NEMSIS) code set. This guide also helps you prepare your database for exporting EMS incident records and detailed demographic information for local, state, and national agency reporting.

NEMSIS is supported in Firehouse 7.5.40 or higher. This guide documents the steps needed to install and implement NEMSIS with a more recent version of Firehouse.


  • Review the entire guide thoroughly before beginning.
  • Do not enter any new EMS incident reports with patients into FH® before you complete this guide.
  • Demographic information is exported independently of the patient information.

Note: While we recommend performing all the items in this guide, you should verify the current requirements to be in full compliance with your local/state reporting body.
