How to Design Your Fire Emergency Plan – Reviewing the Plan 101

Learn how to prevent your plan from being a bottleneck in your project.

So the permit is pulled, but you’ve suffered a series of setbacks with plan’s review. No matter what you do, the Authority Having Jurisdiction (AHJ) keeps kicking the shop drawings back. The project may be delayed because the AHJ won’t approve your plans. Fire protection plan reviews can be one of the most challenging aspects of a project.

But it doesn’t have to be that way. With a little time and patience, plan reviews can not only be far easier, but can be used as a tool to ensure the project goes well.

So, why does the AHJ require a plan review? Plan reviews help ensure the design meets applicable codes and standards, ensures that the design is appropriate for the expected conditions, and the equipment is properly selected. Plan reviews also have the added benefit of detecting problems before the system or equipment is installed. Detecting problems early can save time and/or money.

Obtaining AHJ approvals and passing a fire alarm inspection or acceptance test the first time is not an easy task. Poor design practices, failure to understand code requirements and a general lack of planning can prevent acceptance of design/shop drawings by the AHJ. Poor programming, detector placement, misapplication of products, and other poor installation practices can, and usually do, prevent installers from passing inspections and acceptance tests the first time out.

It is very important to design and install fire alarm systems properly from the beginning. It is also imperative to be ready for the tests when the AHJ comes to witness them. Good planning and execution will save time and money. More importantly, it will result in a better life safety system.

So, you might ask “What’s in it for me?” Getting it right the first time results better relations with authorities having jurisdiction, fewer punch list items, fewer legal problems, and increased pride in workmanship.

Most AHJs require a number of sets to be turned in for plan reviews. This is to ensure that other trades have access and so they can make sure systems such as elevators, suppression systems, HVAC and security systems are properly interfaced.

A good review starts with a complete drawing. Be sure the title block contains all the necessary information for the project. Complete title blocks include the following:

• Name, address and telephone number of the designer
• Address of the protected premises
• Name, address, and telephone number of the contractor(s)
• Drawing revisions must be indicated on each sheet
• Scale, where used
• Indication of North, where appropriate

Drawings that are submitted without title blocks appear incomplete and look unprofessional. Good title blocks are easy to create and can be used as a template for future projects.

Complete drawings will also provide the following:

• Complete floor plans, showing all equipment locations
• A riser diagram
• A reflected ceiling plan or at least ceiling height and type
• Circuit routing
• Typical mounting details
• Typical wiring details
• Room descriptions and uses
• General and specific notes for the installer
• A legend for all symbols used
• A wiring and conduit legend
• A Matrix of Operation
• Power connections

These items are all necessary to ensure a trouble free, code compliant system. Some of the items above may not be recognized as necessary for the proper design and installation of the system. For example,
