What to Do When the Fire Alarm Goes Off — And It’s Not a Fire

The fire alarm blares. Lights flash. People start moving. But… there’s no smoke, no flames, and no sign of danger. Whether it’s burnt toast, steam from a shower, or a system fault, false alarms happen — and they can be confusing.

This guide is for regular users who want to know what to do when the fire alarm goes off — and it’s not a fire.

Step 1: Treat Every Alarm Seriously

Even if you suspect it’s a false alarm, always assume it’s real until proven otherwise. That means:

• Stop what you’re doing
• Leave the building calmly
• Head to the designated assembly point

You can’t know for sure it’s a false alarm until someone trained checks the system.

Step 2: Don’t Try to Silence or Reset the Panel Yourself

Unless you’ve been trained to operate the fire alarm panel, don’t touch it. Silencing or resetting the system without confirming the cause can delay emergency response or mask a real issue.

If you’re curious about how panels work, our How to Operate a Fire Alarm Course is designed for non-technical users. It’s perfect for building managers, office staff, and anyone who wants hands-on confidence.

Step 3: Wait for Instructions

Once outside:

• Stay at the assembly point
• Don’t re-enter the building until given the all-clear
• Follow instructions from staff, fire wardens, or emergency responders

If it’s confirmed to be a false alarm, you’ll be told when it’s safe to return.

Step 4: Report What You Saw

If you noticed anything unusual — like steam, smoke, or someone pressing a manual call point — let staff know. Your input can help identify the cause and prevent future false alarms.

Common Causes of False Alarms

• Cooking fumes or burnt food
• Steam from showers or kettles
• Dust or insects inside detectors
• Faulty or aging devices
• Manual activation by mistake

Regular maintenance and proper detector placement can reduce these issues.
