Reducing Unwanted Fire Signals

Help keep firefighters available for genuine emergencies

Every time Buckinghamshire Fire & Rescue Service responds to an unwanted fire signal (UwFS), firefighters and fire engines are diverted away from real emergencies where lives, property and the environment may be at risk.While fire alarm systems are essential for protecting people and buildings, many unwanted fire signals are preventable. By taking a few simple steps, schools, businesses and other responsible persons can reduce unnecessary fire alarm activations while maintaining high standards of fire safety.

What is an unwanted fire signal?

An unwanted fire signal is when a fire alarm system activates but there is no fire requiring an emergency response.

These activations are sometimes referred to as false alarms, but they are often caused by everyday activities, maintenance work or poor fire alarm management rather than faults with the system itself.

Common causes include:

  • Fire alarm testing carried out incorrectly
  • Dust from maintenance or refurbishment works
  • Steam from kitchens, showers or cleaning
  • Cooking fumes
  • Aerosol sprays
  • Accidental operation of manual call points
  • Poorly maintained fire alarm systems
  • Detector contamination

Why does it matter?

Every unnecessary fire service attendance:

  • Reduces the availability of firefighters and appliances for genuine emergencies.
  • Places unnecessary demand on emergency services.
  • Disrupts staff, visitors and building occupants.
  • Can increase costs and disruption for your organisation.

Good fire safety management helps ensure that when an alarm activates, it is because someone genuinely needs assistance.

Practical steps to reduce unwanted fire signals

Review your Fire Risk Assessment

Whenever significant work or changes take place within your building, review your Fire Risk Assessment to ensure any additional risks are identified and managed.

This may include:

  • Refurbishment projects
  • Changes to escape routes
  • Temporary storage
  • Contractor activity
  • Fire alarm alterations

Manage building works carefully

Summer holidays are often used to carry out maintenance and refurbishment projects.

Construction dust and debris can easily activate smoke detectors.

If detectors need to be temporarily covered:

  • Carry out a suitable risk assessment.
  • Ensure appropriate temporary controls are in place.
  • Remove detector covers immediately once work is complete.
  • Reinstate the fire alarm system as soon as possible.

Brief contractors

Anyone working on your premises should understand:

  • Your fire procedures
  • Evacuation arrangements
  • Assembly points
  • Fire alarm testing arrangements
  • Site-specific risks

Good communication helps prevent avoidable alarm activations.

Train more than one member of staff

Don’t rely on one individual to manage your fire alarm system.

  • Ensure several members of staff know how to:
  • Test the alarm correctly
  • Report faults
  • Respond to activations
  • Contact maintenance providers
  • Liaise with your Alarm Receiving Centre (ARC)

Keep your fire alarm system maintained

Regular servicing and maintenance helps ensure your system operates correctly.

Investigate every unwanted fire signal to identify the root cause and prevent it happening again.

Tell your Alarm Receiving Centre

If your building is connected to an Alarm Receiving Centre (ARC):

Always notify them before:

  • Routine alarm testing
  • Planned maintenance
  • Building works

Make sure they have up-to-date contact details so alarms can be verified before emergency attendance is requested.
