How to Temporarily Turn Off a Fire Alarm in Commercial Buildings

Mammoth Takeaways:

• Fire Alarm Deactivation: Temporarily deactivating a fire alarm should only be done for valid reasons like maintenance or testing, and it requires careful communication with building occupants.
• Fire Alarm Components: Key components include control panels, smoke detectors, heat detectors, manual pull stations, and notification appliances, each playing a vital role in fire safety.
• Troubleshooting Tips: Basic troubleshooting involves resetting the system or replacing faulty parts, but persistent issues should be handled by professionals.

Perhaps your commercial fire alarm system is having false alarms or needs testing or repair? During this situation, you may need to temporarily deactivate your fire alarm system.

This temporary deactivation should not be used to silence low-battery or other nuisance sounds. If your system is chirping or malfunctioning, it’s important to get it serviced right away.

This article will cover the steps you can take to temporarily deactivate your alarm for valid reasons. Misusing this information can leave you, your building, and your occupants at risk.

Step-by-Step Process to Safely Turn Off a Fire Alarm

Assess the Situation

When addressing fire safety, the aim is to always be prepared and protected against the risks of fire. If you’re planning to deactivate your alarm for maintenance or testing, it’s imperative that you’re in a situation where it’s safe to do so. This means there should be no in-progress threats or any high-risk events. A non-functional alarm during an emergency would be a disaster to the health and safety of occupants and the building.

Communicate with Occupants

Inform all people on site of scheduled maintenance when deactivating the fire system. By doing this, it will help prevent panic in case a false alarm happens during testing, and it will give people the chance to plan ahead. It’s also advised to encourage tenants to avoid any hazardous or fire-related activities during this system downtime.

Locate the Control Panel

First, find the control panel(s) in the building to start the process. These units are usually located in dedicated rooms or near the main entrances.

Initiate the Shutdown Sequence

Once at the control panel, the unit may require a key or passcode to gain access to the system. Enter the correct identification code or key to avoid setting off an alarm. Every system is a little different, and it’s important to read and learn the manual of your particular model.

However, generally, the system’s settings will display options that will include the “silence” function. This setting will silence all bells/sirens.

Confirm Deactivation

The panel should display that the system is currently silenced. Display location varies based on the control panel make and model.

Critical Components of a Fire Alarm System

Fire Alarm Control Panels

The processing centers of the fire alarm system are located here. These units feature microprocessors and technology to handle both incoming and outgoing data. This will also be where users interact with the system to check statuses, initiate or silence alarms, and do any internal maintenance.

Smoke Detectors

Smoke detectors use either photoelectric or ionization methods to detect carbon particles in the air. Some units that incorporate both methodologies to reduce false alarms exist as well.

Heat Detectors

These devices, as their name suggests, detect heat. They do so using two available methods: rate-of-rise or fixed temperature. Rate-of-rise uses two thermistors to compare ambient and radiant heat, while fixed-temperature models use a specialized alloy that melts at a predetermined temperature.

Manual Pull Stations

Easily recognizable by their red boxy shape and white handle, these serve as physical activators for the alarm. Manual pull stations rely on an individual to activate when a fire is spotted.

Notification Appliances

If there is a fire, these equipment pieces inform the people who are present. These could be sirens, strobes, vibrations, text messages, voice alerts, and any combination of these.  

Precautions and Safety Measures

Importance of Safety Protocols

Safety protocols exist for the sole purpose of protection. Follow the proper steps to ensure everyone’s safety and protection in emergencies. Failing to follow protocol can result in damage and loss of life.

Avoiding Panic Among Occupants

Always have clear open communication with the occupants of the building. Inform them about any changes, updates, or tests on the building’s safety equipment. Post signs, send emails, or use other means of communication to make sure that everyone is aware of the dates and times of safety-related activities.

Keeping Emergency Exits Clear

Emergency exits should be clear at all times. Blocked exits during an emergency spell disaster. If you see any blocked emergency exits or manual pull stations, clear the pathway or inform the proper authorities to rectify the situation. Blocking any exits at any time goes against the NFPA 72 regulations.

Common Reasons for False Alarms

Environmental Factors

Environmental factors such as dust, humidity, or excessive light can trigger false alarms in smoke detectors and sensors. Place devices correctly as per NFPA guidelines and inspect and clean regularly.

Equipment Malfunctions

Sometimes wiring breaks down, a sensor isn’t calibrated properly, or a unit is reaching the end of its life. These malfunctions can trip the alarm and cause false positives. When malfunctions occur, schedule a licensed fire technician to do a thorough inspection of the fire alarm system. Professionals will be able to identify these issues and also repair them to get your fire alarm up and running properly.

Human Error

Sometimes people ignore rules and regulations and set off an alarm. Smoking or vaping in unauthorized areas or tampering with pull stations is a possible cause. Posting clear signage and instructions can help reduce these errors.

Troubleshooting Malfunctioning Fire Alarms

Identifying Common Issues

If your fire alarm is malfunctioning, it may be due to sensor issues, wiring problems, or outdated equipment. It could also be environmental interference. Identifying the root cause is the first step in troubleshooting.

Steps for Basic Troubleshooting

Try resetting the alarm system or replacing faulty components if possible. If the problem persists, it may be time to call in professionals.

When to Contact Professionals

If you can’t fix the problem yourself or if the system keeps malfunctioning, reach out to a professional fire alarm service company. They can diagnose and repair more complex issues.
