City of Charlotte - Fire Department and Mecklenburg County Code Enforcement Fire Alarm & Detection Systems Plan Review Requirements   

Introduction

This joint policy was developed in response to customer comments regarding the fire drawings submittal process. The purpose of the policy is two-fold:

  • Speak with one voice
  • Provide customers with concise guidelines for Fire Alarm & Detection Systems Plan Review Requirements
  • Improve inspector efficiency and uphold all issues regarding life/safety

 

Current Process: Sprinklers

In an effort to collect additional information about sprinkler systems before buildings are constructed, the Charlotte Fire Department and the Mecklenburg County Engineering and Building Standards Department (now known as Code Enforcement Department) revised their permit application process. Beginning October 1, 1997, permit applications required plan submittal on new building or additions with sprinklers in one of the following ways:

  • Include sprinkler plans and hydraulic calculations in the architectural packages; or
  • Include sprinkler head locations (for all uses other than industrial or storage) and design criteria. In some cases riser diagrams were also required.

If the second option was selected, the sprinkler contractor shop drawing submittal was required as a plan revision to the previously reviewed plans, with the submittal indicating the original 6-digit tracking number.

2.1 Current Process: Fire Alarms

Similar to the above sprinkler submittal requirements in either one of the following ways:

  • Include a fully developed and detailed alarm design; or

A. Construction Documents

Construction documents for fire alarm systems shall be submitted for review and approval prior to system installation. For the purpose of this guideline architectural plans will be considered as construction drawings. Such drawings shall include, but not be limited to, all of the following:

  1. A floor plan
  2. Locations of alarm-initiating and notification appliances
  3. Alarm control and trouble signaling equipment
  4. Annunciation
  5. Power connection
  6. Architectural reflected ceiling plans with ceiling types and heights
  7. The interface of fire safety control functions

 

B.  Contractor Identification

Technical documentation bearing the name, address, and phone number of the system designer and installing contractor shall be available on-site for review and acceptance by the fire inspector and, shall include the following:

  1. Battery calculations
  2. Conductor type and sizes
  3. Voltage drop calculations
  4. Manufacturers, model numbers and listing information for equipment, devices and materials

C.  Fees

Appropriate fire alarm plan review fee and performance test fee(s) will be charged at the time of architectural review. Additional performance test fee(s) may be charged if fire alarm system performance field tests reveal system deficiencies and/or if contractor schedules a fire alarm system test and is not ready when fire inspector arrives on site. 

Disclaimer

The purpose of the preceding plan submittal criteria is to serve as an aid to A&E's in preparing permit drawings for submittal.  This list does not replace the need for shop drawing review; those will still be required in the field.  In addition, while this list fairly resembles the information needed by Fire Marshals in their review, actual shop drawing submittal requirements may vary, as job conditions dictate, at the discretion of the Fire Marshal.

Timing

This joint policy between Charlotte Fire and Code Enforcement will be become effective April 3, 2006.
