On most multifamily projects, the last thing standing between a finished building and its certificate of occupancy is the life-safety inspection. Fire alarm acceptance, emergency lighting tests and detector verification are scheduled late, involve outside parties, and fail for small reasons. When they fail, turnover slips and the lease-up calendar slips with it. Here is what gets checked and how to keep it off the critical path.
Fire alarm acceptance test
The fire marshal (or the AHJ’s designee) witnesses a test of the complete system: every initiating device (pull stations, smoke and heat detectors, sprinkler waterflow and tamper switches) and every notification appliance (horns, strobes, speakers). The system has to report to the monitoring company, the elevator recall has to work, and the record of completion has to match what is on the wall. Common failures are devices missing from the as-built drawings, strobes that do not synchronize, and a monitoring account that was never activated.
Emergency and exit lighting
Egress paths, stairs, corridors and exterior exit discharge need lighting that stays on when normal power fails, for at least 90 minutes. Inspectors trip the breaker and walk the path. Battery packs that were installed months earlier and never charged, or fixtures wired to the wrong circuit, are the usual problems. Testing every unit a week ahead of the inspection, not the day of, catches them.
Smoke and carbon monoxide detection in units
Each apartment gets smoke alarms in every bedroom, outside sleeping areas and on each level, interconnected so they all sound together, with battery backup. Carbon monoxide detection is required where there are fuel-burning appliances or an attached garage. On a building with 150 units, that is several hundred devices, and the inspector will sample. Keeping the unit layouts identical floor to floor makes the sample pass.
Emergency responder radio coverage
Larger and below-grade buildings often need a test of public-safety radio coverage inside the building. Where signal strength falls short, an in-building amplification system (often called ERRCS or public-safety DAS) has to be designed, installed and tested. This is a specialty system with its own survey, permit and acceptance test, and it is frequently discovered late. Ask the fire marshal about it at the first plan review.
Elevator, fire pump and generator connections
Where the building has them, elevators need shunt-trip and recall wiring, fire pumps need their dedicated service, and a generator needs transfer switches tested under load. Each has its own inspection, usually by a different inspector, and each depends on the fire alarm being operational first.
How we keep it off the critical path
- Submit fire alarm shop drawings early, because the AHJ’s review time is outside anyone’s control.
- Pre-test every device ourselves and fix the punch list before the witnessed test is scheduled.
- Energize and charge emergency lighting as soon as permanent power is on, not at the end.
- Keep the as-builts current as devices are added or moved, so the record of completion matches the building.
- Confirm the monitoring account and phone or cellular path are live a week before the test.
