Fire alarms need to be your first choice since they operate on a round-the-clock basis in detecting fires. However, patrols are essential when the alarm does not work; a well-trained patrol walks through the building to look out for fire and call the fire department until the alarm is repaired.
Most guides stage a contest. This one judges each option by how it fails, not by what it promises. The guidance published by The Fast Fire Watch Company draws the same line, noting that remote Fire Watch Security monitoring goes quiet in exactly the zones that are impaired.
Which Detects Fire Faster?
Alarms, almost every time. The alarm responds to the smoke right away, whereas the guard is able to detect the fire only if he coincidentally walks by. This is the reason why the code calls for rapid patrols: for example, in Brookhaven, New York, patrols should be conducted every 15 minutes if the building is occupied, every 30 minutes if unoccupied, and 24/7 in areas where people sleep.
Takeaway: If the alarm is working properly, the guards are a second option.
| Factor | Alarm system | Fire watch patrol |
| Detection | Automatic, continuous | Human, at each round |
| Blind spot | Dead or missing batteries, impaired zones | Time between rounds |
| Proof of action | Panel event history | Signed patrol log |
| Best role | Standing protection | Temporary cover during impairment |
How Do Alarms Fail?
Mostly through neglect. According to the Fire Engineering website, “NFPA’s research from 2007 to 2011 found that 47% of nonfunctioning alarms have missing or disconnected batteries and 24% have dead batteries. In cases where there was no alarm system, the risk of death was double.
The same is true for patrols – a guard who does not do his rounds and does not sign the log provides no evidence of inspections. The Fast Fire Watch Company describes trained guards who document every round. For homeowners, the fire watch security question often starts with a monthly test-button press.
When Must Patrols Replace Alarms?
When a required system is impaired past a local time limit, and limits vary. Four hours of power loss in Reno, Nevada, calls for either evacuation or fire watch according to NFPA 101 and IFC 901.7. However, Denver Fire Department guidelines require ten hours before taking action. Ask the local fire authority about that.
In case of system failure, it is important to take the following actions:
- Notify the fire department and alarm company, and notify affected tenants.
- Find out the local requirements for time and patrols and get them in writing.
- Appoint a special guard without any other tasks.
- Write down every round with time and signature.
- Stay at your post until the system is fixed, tested, and accepted by authorities.
Seattle Fire Department leaves the option of who will patrol the premises and doesn’t mandate the use of a security firm. In some jurisdictions, professional fire watch security is optional, while in other places it is required. Check with the local fire department. The Fast Fire Watch Company recommends getting the requirements in writing, as it resolves all possible disputes between owner, supplier, and guards.
What will happen if you ignore it?
The costs are human and financial. Fox 5 Atlanta reported a lawsuit alleging a landlord ignored fire watch rules before a 74-year-old resident died in a February 2023 apartment fire. These are allegations, not findings.
On money, the Meadville Tribune reported that a Pennsylvania high-rise stayed on watch for 59 weeks while a replacement alarm costing nearly $600,000 went in. The Fast Fire Watch Company’s write-up of that case shows why planning coverage before an outage beats scrambling after. A report by the law firm Taylor Wessing has shown that one UK-based landlord was paying £28,000 per month for his waking watch. Remember to price the period of time rather than the daily rate since the cost of fire watch security services is dependent on the time taken to make the repairs.
| Jurisdiction | Rule | Source |
| Reno, NV | Evacuate or fire watch after 4+ hours down in 24 | Reno Fire Dept. |
| Denver, CO | Fire watch after 10+ hours | Denver Fire Dept. |
| Brookhaven, NY | Rounds every 15 min (occupied), 30 min (unoccupied), continuous (sleeping) | Town of Brookhaven |
| Seattle, WA | Dedicated watch day and night; security company not required | Seattle Fire Dept. |
Which Should You Choose?
You layer them. Keep tested alarms as the standing defense, and line up patrol coverage before an outage forces the decision. A provider such as The Fast Fire Watch Company can supply trained guards who log each round, so your plan needs a phone number, not improvisation. Ask your fire marshal for the required interval, then write the plan down. That is what fire watch security is really for: covering the gap.
FAQs
Can a fire alarm replace a fire watch?
No. Where devices are impaired, they cannot detect fire, so a person must.
Can I do my own fire watch?
Sometimes. Seattle lets owners pick personnel, but the watcher must be dedicated to the task.
How long does a fire watch last?
Until the system is repaired, tested, and accepted by the authority. The Pennsylvania case ran 59 weeks.
Cover the Gap, Not the Contest
The best buildings quit worrying about which choice wins out. They check the alarm system to see that it’s working, know the local hours for alarm triggers, and have a patrol plan prepared in advance. Once the alarm system fails, the people on the ground serve as the sensors, and they write down their activities.
