Fire Watch Requirements in Dallas-Fort Worth: What to Do When Your Fire Alarm System Goes Down

At some point, every fire alarm system goes out of service — a panel failure, a monitoring outage, a major renovation, or planned maintenance that takes detection offline. What happens during that gap matters as much as what happens when the system is running. If your building's fire alarm is down for more than a few hours, Dallas-Fort Worth fire officials expect you to have a fire watch in place, and not knowing that requirement is one of the fastest ways to end up with a citation or a forced evacuation order.

Here's what commercial building owners, property managers, and facility managers across DFW need to know about fire watch requirements and how to handle a system outage without putting people or your occupancy permit at risk.

When a Fire Watch Is Required

A fire watch is a temporary, human-staffed substitute for automatic fire detection. It's required any time your fire alarm system — or a significant part of it, such as monitoring, detection in a specific area, or the notification appliances — is out of service and can't be restored quickly. Local fire codes in Dallas, Fort Worth, Arlington, and surrounding jurisdictions generally follow NFPA 72 and the International Fire Code in requiring a fire watch when a system will be down for more than four hours in a 24-hour period. Some AHJs (authorities having jurisdiction) apply a stricter standard for high-occupancy buildings, hospitals, or high-rises, so it's worth confirming the exact threshold with your local fire marshal's office rather than assuming the four-hour rule applies everywhere.

What NFPA 72 and Local Fire Codes Say

NFPA 72 doesn't spell out fire watch procedures in detail — that's covered by the fire code your municipality enforces — but it does require that any impairment to a fire alarm system be reported to the AHJ and to the monitoring company, and that compensating measures be put in place until the system is restored. In practice, that means notifying the fire marshal's office before or as soon as the outage begins, not after the fact. Waiting to report an impairment, or restoring the system without ever having reported it, is itself a violation independent of the outage.

Who Can Perform a Fire Watch

A fire watch doesn't require a licensed technician — it requires a person who is present, trained on what to look for, and equipped to act. That means someone patrolling the affected areas at intervals set by the AHJ (commonly every 30 to 60 minutes), carrying a portable means of notifying the fire department, and familiar enough with the building to recognize a fire condition and evacuate occupants if needed. Many owners use existing security staff for this role, but only after confirming with the fire marshal that the assigned staff and patrol frequency meet local expectations.

What a Compliant Fire Watch Looks Like

A fire watch isn't just a person standing near the front desk. It needs a defined patrol route covering every area the impaired system would normally protect, a documented schedule, and a working means of communication — a cell phone is usually sufficient, but it needs to be tested and charged. If the building has areas the fire alarm would normally monitor but a person can't easily reach on a short interval, such as mechanical penthouses or parking structures, the AHJ may require additional watch staff or a faster patrol cycle in those zones.

Documentation Your Fire Marshal Will Want to See

Every fire watch shift should be logged: who patrolled, when, what areas were covered, and any conditions observed. This log isn't optional paperwork — it's what demonstrates compliance if the fire marshal visits during the outage or asks for records afterward. Keep a copy of the impairment notification you sent to the AHJ and monitoring company alongside the watch logs, and don't discontinue the fire watch until the system has been tested, restored, and the AHJ and monitoring company have been notified that the impairment is over.

Getting Your System Back Online Faster

The best fire watch is a short one. When a system goes down, the priority is diagnosing the cause and getting a technician on-site as quickly as possible — most panel faults, monitoring outages, and detector failures can be resolved same-day if a qualified technician is available. Building owners who have an existing service relationship with a fire alarm contractor typically get faster response than those calling around during an active outage.

Schedule an Inspection Before It Becomes an Outage

Most fire watch situations are preventable. Regular NFPA 72 testing catches failing batteries, aging panels, and wiring faults before they force your system offline.
