Permitting, Documentation, Jobsite Safety, and Business Practices
Paperwork that protects the job
Most jurisdictions require a fire alarm permit and plan review before installation. Submittals typically include working drawings showing device locations and spacing, riser/wiring diagrams, a sequence of operation matrix, battery and voltage-drop calculations, cut sheets for listed equipment, and the contractor's license and qualifications. At completion, the package includes the Record of Completion, as-built drawings, the owner's operation and maintenance manual, and documented training of the owner's staff. Changes during construction are handled with change orders - never installed informally and reconciled later.
Safety on site
Fire alarm work happens in occupied buildings and in energized panels. Use lockout/tagout on the dedicated fire alarm circuit before working in the control unit, keep temporary power GFCI-protected (the permanent fire alarm circuit is the exception), use fall protection and correct ladder practice, and never leave an impairment without notice. Before any device is disabled, obtain authorization, log the event, arrange a fire watch if the system is out of service, and restore and verify before leaving the site. Protect devices from construction dust and paint; a detector contaminated during construction is a false alarm waiting to happen.
Traps: assuming a verbal OK is an approval; starting rough-in before plan review returns; leaving the system in test mode or a NAC disconnected over a weekend; and putting a change in scope in an email instead of a change order.
Rule of thumb: if it is not on the drawing, in the record of completion, or on a signed change order, it did not happen.
