Why You Shouldn’t Ignore a Fault Showing on Your Fire Alarm Panel

A warning light, fault message or intermittent beeping from your fire alarm panel can be easy to put off, particularly when everything else in the building appears to be working normally.

But a fire alarm fault shouldn’t simply be ignored.

Your fire alarm system plays a critical role in protecting people and property. A fault indication is the system telling you that something requires attention, and until the cause has been identified, you may not know whether part of your fire detection system is operating correctly.

At Safe & Sound Fire Ltd, we help businesses and organisations maintain reliable fire alarm systems across Glasgow, Edinburgh and surrounding areas.

Here are some of the reasons you should take a fire alarm panel fault seriously.

What Does a Fire Alarm Panel Fault Mean?

A fire alarm control panel continually monitors different parts of the system.

When it identifies an issue, it can display a fault indication or sound a warning buzzer to alert the person responsible for the premises.

Importantly, a fault signal is not the same as a fire alarm activation. It generally indicates that the system has detected a problem that needs investigating.

The exact cause can vary depending on the system and the fault being displayed.

What Can Cause a Fire Alarm Fault?

There are many potential reasons why a fire alarm panel may show a fault.

These can include:

  • Problems with detectors or manual call points
  • Wiring or circuit faults
  • Power supply problems
  • Backup battery issues
  • Communication faults
  • Damaged or disconnected devices
  • Issues with sounders
  • Problems following alterations to the building
  • Component or equipment failure

The panel may provide information that helps identify the affected area, circuit or device, but the underlying cause should be properly investigated.

Don’t Assume the Rest of the System Is Working

One of the dangers of ignoring a fault is assuming that because the panel is still powered up, the entire fire alarm system must be operational.

That isn’t necessarily the case.

Depending on the nature of the fault, part of the system could potentially be affected. This might involve a detector, circuit, sounder or another component.

Without investigating the fault, you may not know exactly what is and isn’t operating as intended.

Fire Alarm Systems Are There to Provide Early Warning

The purpose of a fire alarm system is to detect or report a fire and provide an effective warning so occupants can respond and evacuate.

In an emergency, every second can matter.

If a fault has affected part of the system, its ability to provide the intended level of warning could potentially be compromised.

That’s why faults should be investigated rather than repeatedly silenced or left for another day.

Repeatedly Silencing the Panel Doesn’t Fix the Problem

A common response to an audible fault warning is to silence the panel buzzer.

While this may stop the noise, it doesn’t necessarily remove the underlying fault.

If the warning returns, or the fault indication remains on the panel, further investigation is needed.

Simply silencing a warning without dealing with its cause could allow a problem to remain unresolved.

Power Supply and Battery Faults Shouldn’t Be Overlooked

Fire alarm systems typically have a mains power supply alongside standby batteries designed to support the system if mains power is interrupted.

A fault relating to either power source deserves attention.

Backup batteries don’t last indefinitely, and problems can develop with batteries, chargers or other parts of the power supply.

If your panel is indicating a power-related issue, arranging professional investigation can help establish what needs to be repaired or replaced.

Building Work Can Sometimes Lead to Fire Alarm Faults

Have you recently had electrical work, refurbishment or alterations carried out at your premises?

Changes within a building can sometimes affect fire alarm equipment or wiring.

Devices may have been disconnected, cables could have been disturbed, or changes to the layout of the building may mean the existing system needs reviewing.

If a fault appears during or following building work, don’t assume it will simply disappear once the work is finished.

Keep a Record of Fire Alarm Faults

Fire safety management involves more than simply having a fire alarm installed.

Any faults, servicing, testing and remedial work should be appropriately recorded as part of the building’s fire safety records.

If a recurring fault keeps appearing, those records can also provide useful information to the engineer investigating the problem.

Regular Servicing Can Identify Developing Problems

Waiting for a major fault isn’t the best way to manage a fire alarm system.

Routine inspection, testing and servicing can help identify problems, deteriorating components and other issues that may need attention.

It also provides an opportunity to check that the system remains appropriate for the premises and is being maintained correctly.

However, scheduled servicing shouldn’t be used as a reason to postpone investigating a fault that is already showing.

If your panel is displaying a problem now, it should be addressed.

What Should You Do If Your Fire Alarm Panel Shows a Fault?

If you notice a fault indication, don’t simply ignore it.

Check the information displayed on the panel and follow the procedures established for your premises. Make the person responsible for fire safety aware of the issue and arrange for a competent fire alarm professional to investigate where required.

You should avoid attempting repairs or making alterations to the fire alarm system unless you are suitably competent to do so.

Is Your Fire Alarm Panel Showing a Fault?

A fault light or warning message is there for a reason.

Even if there are no obvious signs of a problem elsewhere in the building, getting the fault investigated can help ensure your fire alarm system continues to provide the protection expected of it.
