Field impact

What matters on a fire alarm project

The city plan-review form explicitly identifies fire alarm as a Fire Marshal review category.
Hartford’s Knox Box page states that buildings with automatic alarm or suppression systems generally require a rapid-entry key lock box, except listed occupancies such as qualifying owner-occupied one- and two-family dwellings.
Treat the Knox Box requirement as part of project closeout coordination when applicable—not as a fire alarm programming item.

Pre-submittal

Contractor checklist

Use the current Fire Marshal plan-review application.
Verify plan-review fee and submission location with Licenses & Inspections.
Confirm whether the project triggers Hartford’s rapid-entry key lock box requirement.
Coordinate final acceptance and building closeout with the Fire Marshal and other required departments.
