Complete system floorplans
Device layouts, notification coverage, and detection that match how the building will actually be built and wired.
Services
Fire alarm design—handled.
We take fire alarm design completely off your plate. You install. We handle the design and the paperwork.
Request a project rateNFPA-compliant drawings
Code-compliant design per current NFPA standards, documented clearly enough for plan review and the field.
Battery & voltage drop calculations
The numbers AHJs expect to see—complete, checkable, and tied to the drawings, not a last-minute spreadsheet.
Riser diagrams & system details
Risers, typical details, and notes installers can work from without a round of RFIs on day one.
AHJ-ready submittal packages
One package, ready to stamp and send. Less back-and-forth with plan reviewers, faster approvals.
Revisions, resubmittals & as-builts
When comments come back—or the field changes—we stay on the package through closeout documentation.
How it works
From scope to as-builts, without a designer on payroll.
01
Send the scope
Drawings, spec, AHJ, and timeline. A bid set or a sketch is enough to start.
02
We design
Floorplans, calculations, risers, and notes—built the way contractors install.
03
You submit
AHJ-ready package you can put in the quote and send to plan review.
04
We stay on it
Comments, revisions, and as-builts without you staffing a designer.
What we are not
A design partner. Not a competing contractor.
Northline does not bid installation against you. We design for electrical contractors and fire alarm installers—so the package that hits the field is one your crew can build.
Every package includes
- Code basis and AHJ notes
- Device legend and typical details
- Calculation backup
- Revision tracking when comments come back
Need a design rate for a bid that’s going out?
Send a scope or a set of drawings. We’ll return a project-based design rate you can put straight into your bid.
