We also provide a detailed service report for your fire safety records. This documents the work completed, highlights any issues identified and helps you maintain an accurate record of your fire alarm system’s maintenance history.

Fire Extinguishers

You are legally responsible for ensuring that suitable fire extinguishers are provided on your premises. The number and type required will depend on your building, its use and the fire risks present.

A fire risk assessment helps identify the appropriate fire extinguishers and any additional equipment needed to protect your premises and support compliance with relevant fire safety requirements.

Fire Safety Training

Fire safety training is an essential part of protecting your employees and maintaining a safe workplace. It helps staff understand fire risks, recognise potential hazards and respond appropriately in an emergency.

Under the Regulatory Reform (Fire Safety) Order 2005, employers and other responsible persons must ensure employees receive appropriate fire safety training. Effective training helps your team understand evacuation procedures and the actions to take in the event of a fire.

Emergency Lighting

Emergency lighting is an essential part of a building’s fire safety arrangements. It helps businesses meet their fire safety responsibilities under the Regulatory Reform (Fire Safety) Order 2005 by providing illumination when normal lighting fails.

In the event of a power cut or mains lighting failure, emergency lighting helps occupants identify escape routes and safely evacuate the building. A properly designed and maintained system provides vital visibility during an emergency.

Fire Alarm Monitoring

Our monitored fire alarm systems provide round-the-clock monitoring, 24 hours a day, 365 days a year, helping protect your premises even when the building is unoccupied.

As a result, when your fire alarm is activated, a signal is sent to an alarm receiving centre, enabling prompt notification of designated keyholders and, where applicable, the fire and rescue service in accordance with the agreed response procedures.

Aspirating Systems

Aspirating smoke detection systems provide highly sensitive fire detection, helping identify smoke at an early stage before a fire has time to develop. They are particularly useful in environments where early warning is essential.

These systems continuously draw air samples through a network of sampling pipes and analyse them for smoke particles. As a result, the system can detect smoke early and help protect valuable equipment, sensitive environments and business-critical areas.

Fire Suppression

Fire suppression systems are designed to detect and control fires quickly, helping protect people, property and valuable assets. They provide specialist fire protection for environments where conventional fire extinguishers or sprinkler systems may not be suitable.

Depending on the risks involved, these systems can use different suppression agents to help limit fire damage and reduce disruption to your business. Our team can advise on suitable solutions for your premises and fire safety requirements.

Frequently Asked Questions About Commercial Fire Alarm Systems

SS Systems designs, installs, upgrades and maintains commercial fire alarm systems for a wide range of buildings and organisations.

Our solutions include:

  • Conventional fire alarm systems: Divide a building into detection zones and identify the zone where an alarm originates.
  • Addressable fire alarm systems: Identify individual detectors, manual call points and other devices to help staff locate alarm events more precisely.
  • Wireless fire alarm systems: Use radio communication between compatible devices to reduce the need for extensive cabling.
  • Hybrid fire alarm systems: Combine wired and wireless technology where the design and equipment support this arrangement.

Our team assesses the building’s layout, use, occupancy and fire safety requirements before recommending a suitable system.

SS Systems supports commercial properties, educational premises, heritage buildings, public-sector organisations and other non-domestic environments.

The right fire alarm system depends on your building’s fire risks, layout, occupancy and evacuation strategy.

A competent designer should consider:

  • The findings of your fire risk assessment
  • The building’s size, layout and number of floors
  • How people use the premises
  • The number and location of occupants
  • The required detection and alarm coverage
  • Potential sources of unwanted alarms
  • Connections to other fire safety or building systems
  • Future expansion and maintenance requirements

SS Systems offers site surveys and bespoke fire alarm system design to help customers choose equipment that suits their premises.

A smaller building may suit a conventional system, while a larger or more complex site may benefit from addressable technology. Wireless systems can offer practical advantages where cabling would cause significant disruption.

The fire safety strategy and system design should determine the final choice rather than price or building size alone.

Conventional and addressable fire alarm systems both provide fire detection and warning, but they identify alarm locations differently.

  • Conventional systems: Group detectors and manual call points into zones. The control panel identifies the affected zone rather than the exact device.
  • Addressable systems: Assign an individual address to each compatible device. The control panel can identify which detector or call point triggered an event.

Addressable systems can help building staff and engineers investigate events more efficiently, particularly across larger premises.

Conventional systems may provide a suitable and economical solution for smaller, straightforward buildings.

Both technologies require appropriate design, installation, testing and maintenance.

SS Systems can assess your premises and recommend the most appropriate option for your fire safety requirements.

Wireless fire alarm systems can provide a suitable solution for many commercial premises when competent designers select appropriate equipment and confirm reliable radio communication.

In particular, wireless technology can offer advantages in:

  • Listed and heritage buildings
  • Occupied offices and commercial premises
  • Schools and educational buildings
  • Properties where extensive cabling would cause disruption
  • Buildings with difficult installation routes
  • Temporary or changing layouts, where the system design permits

However, wireless systems still need suitable detector positioning, dependable communication, battery monitoring and regular maintenance.

The designer should also assess signal coverage, interference risks and the requirements of BS 5839-1:2025 and applicable equipment standards.

SS Systems offers wireless fire alarm solutions alongside conventional and addressable systems.

BS 5839-1:2025 provides the principal British Standard code of practice for the design, installation, commissioning and maintenance of fire detection and fire alarm systems in non-domestic premises.

It covers important considerations such as:

  • System categories and the intended level of protection
  • Detector and manual call point positioning
  • Alarm warning arrangements
  • Control and indicating equipment
  • Power supplies and fault monitoring
  • Commissioning, documentation and handover
  • Routine testing, inspection and maintenance

Other standards may apply to particular equipment or specialist arrangements.

In England and Wales, the Regulatory Reform (Fire Safety) Order 2005 also establishes relevant fire safety duties for responsible persons.

British Standards provide technical recommendations; meeting a standard does not automatically satisfy every legal requirement for a particular building.

SS Systems designs and maintains commercial fire alarm systems with reference to the relevant British Standards and fire safety requirements.

Commercial fire alarm systems need regular user testing and professional servicing to help maintain reliable operation.

For typical non-domestic systems, BS 5839-1:2025 recommends:

  • Weekly user testing: Operate a suitable manual call point in accordance with the site’s testing procedure, normally rotating the call point used.
  • Periodic professional servicing: Arrange inspection and servicing by a competent person at intervals not exceeding six months.
  • Additional attention: Investigate faults, unwanted alarms and significant system changes without waiting for the next scheduled visit.

The building’s risk assessment, system design and specific operating conditions may justify additional checks.

SS Systems offers planned fire alarm maintenance for systems that we install and suitable existing systems from other providers.

Keep records of user tests, servicing, faults and corrective work in your fire alarm logbook or an appropriate digital system.

Yes. SS Systems provides maintenance, repair and upgrade services for suitable commercial fire alarm systems, including equipment that another company originally installed.

Our team can assess the existing installation and discuss options such as:

  • Planned inspection and servicing
  • Fault investigation and repairs
  • Replacement of damaged or obsolete devices
  • Control panel upgrades
  • Additional detection and alarm coverage
  • System extensions following building alterations
  • Review of compatible monitoring and integration options

Before recommending an upgrade, an engineer should assess equipment compatibility, the system’s condition and the requirements of the current fire safety strategy.

Some older installations may require more extensive replacement if suitable parts or compatible equipment are unavailable.

SS Systems can discuss a maintenance takeover or upgrade following an assessment of your premises.

Many commercial fire alarm systems can communicate with compatible fire safety, access control and building management equipment.

Depending on the approved design, potential connections include:

  • Access control: Release relevant electrically controlled doors when the fire strategy requires it.
  • Automatic opening vents: Trigger appropriate smoke ventilation functions through the agreed cause-and-effect arrangements.
  • Smoke control systems: Initiate relevant controls and status functions.
  • Voice alarm systems: Coordinate warning messages and evacuation procedures.
  • Lifts: Initiate suitable recall or other functions where the building design requires them.
  • Remote monitoring: Transmit appropriate alarm or fault signals through compatible monitoring equipment.

To ensure reliable operation, competent designers should specify each interface and document how the connected systems must respond.

In addition, engineers must test the relevant cause-and-effect functions during commissioning and subsequent maintenance.

SS Systems provides fire alarm and access control services and can discuss suitable integration arrangements for your premises.

A suitable commercial fire alarm system can connect to an alarm receiving centre through compatible signalling equipment and an appropriate monitoring agreement.

As a result, authorised monitoring staff can receive alarm signals even when your premises have no on-site personnel.

Before arranging monitoring, confirm:

  • The fire alarm panel’s compatibility with the signalling equipment
  • The available communication paths
  • Which alarm and fault signals the service will receive
  • The monitoring provider’s response procedures
  • Keyholder contact details and escalation arrangements
  • Any requirements from your fire safety strategy or insurer

However, monitoring does not guarantee an automatic fire and rescue service response. The monitoring provider and local fire and rescue service may apply specific procedures.

SS Systems can also discuss remote fire alarm monitoring options and suitable arrangements for your premises.

Contact SS Systems to discuss a new commercial fire alarm system, an upgrade to an existing installation or a planned maintenance contract.

Advice When Choosing and Maintaining Commercial Fire Alarm Systems

Before selecting a commercial fire alarm system, review your fire risk assessment and the evacuation strategy for your premises.

These documents help establish the level of fire detection and warning that your building needs.

Consider:

  • The building’s size, layout and occupancy
  • The activities and fire hazards within the premises
  • People who may need assistance during evacuation
  • The required fire alarm system category
  • Escape routes and areas requiring detection
  • Whether occupants need phased or simultaneous evacuation
  • Connections to other fire safety systems

Discuss these findings with a competent fire alarm designer before approving a system proposal.

SS Systems offers site surveys and bespoke commercial fire alarm design to help customers select solutions appropriate to their buildings.

Do not assume that a system suitable for one commercial property will meet the needs of another.

Understand the advantages and limitations of different fire alarm technologies before deciding which system suits your premises.

Consider the following options:

  • Conventional systems: Provide zone-based alarm identification and may suit smaller, straightforward buildings.
  • Addressable systems: Identify individual compatible devices and can simplify event investigation across larger or more complex premises.
  • Wireless systems: Reduce cabling requirements and can help minimise disruption in occupied or heritage buildings.
  • Hybrid systems: Combine wired and wireless components where the equipment and system design support the arrangement.

Ask your provider to explain how each option affects installation, ongoing maintenance, future expansion and fault identification.

Review the full system requirements rather than choosing solely on initial installation cost.

SS Systems can assess your building and recommend suitable conventional, addressable or wireless fire alarm technology.

Choose a provider that understands the technical requirements for commercial fire detection and alarm systems.

BS 5839-1:2025 provides recommendations for the design, installation, commissioning and maintenance of fire alarm systems in non-domestic premises.

Before appointing a contractor, ask about:

  • Experience with buildings similar to yours

  • Commissioning and handover procedures
  • Maintenance and fault support arrangements

SS Systems advertises BAFE registration and SSAIB certification, alongside wider industry accreditations.

Check the current scope of any certification when assessing a provider. Certification supports confidence in relevant processes but does not remove the need to review the suitability of the proposed system.

Make sure the fire alarm design provides appropriate detection and warning throughout the areas that require protection.

Detector selection and positioning depend on the environment, fire risks and required system category.

Ask your designer to consider:

  • Smoke detectors: Suitable locations where smoke detection provides an appropriate response.
  • Heat detectors: Areas where environmental conditions may make smoke detection unsuitable.
  • Manual call points: Appropriate positions along escape routes and at relevant exits.
  • Alarm sounders: Suitable warning levels throughout the protected areas.
  • Visual alarm devices: Additional warning arrangements where the building’s needs justify them.
  • Specialist detection: Appropriate technology for high ceilings, difficult environments or particular hazards.

Consider background noise, room use, ceiling height and any environmental conditions that could affect detection.

Ask the designer to explain how the system supports the building’s evacuation strategy.

Do not add or relocate devices without reviewing the impact on the overall design.

Identify any equipment that needs to respond when the fire alarm activates.

Many commercial buildings rely on coordinated operation between fire alarms and other safety systems.

Potential interfaces include:

  • Access-controlled doors and relevant locking arrangements
  • Automatic opening vents and smoke control equipment
  • Lift recall functions
  • Voice alarm and public address systems
  • Relevant ventilation controls

Ask your designer to prepare a clear cause-and-effect specification that describes what each system should do during different fire alarm conditions.

Arrange suitable testing of the interfaces during commissioning and maintenance.

SS Systems offers commercial fire alarm and access control services and can discuss the integration requirements for your premises.

Never assume that two systems will communicate correctly simply because both support an interface connection.

Set up a fire alarm testing and servicing programme before the system enters normal use.

For typical non-domestic installations, BS 5839-1:2025 recommends weekly user testing and professional inspection and servicing at intervals not exceeding six months.

Your programme should include:

  • Weekly tests: Follow the agreed procedure and rotate the manual call point used where appropriate.
  • Professional servicing: Arrange competent engineers to inspect and test the system at suitable intervals.
  • Fault management: Investigate faults and arrange corrective work promptly.
  • Battery checks: Follow the relevant maintenance procedures for standby power supplies.
  • Device testing: Maintain an appropriate programme for checking detectors, call points and warning devices.
  • Records: Keep a clear log of tests, servicing, faults and repairs.

Tell relevant occupants and any alarm receiving centre before carrying out tests where your procedures require notification.

SS Systems offers planned fire alarm maintenance, including servicing for suitable existing installations.

Remote monitoring can support fault awareness, but it does not replace physical inspection and testing.

Frequent unwanted fire alarms can disrupt your business, undermine confidence in the system and create unnecessary call-outs.

Work with your fire alarm provider to identify and address the underlying causes.

Common contributors include:

  • Unsuitable detector types in kitchens or dusty environments
  • Steam, aerosols and other environmental influences
  • Poor detector positioning
  • Contamination or equipment faults

Ask a competent engineer to review repeated activations and recommend suitable improvements.

Do not disable detectors or change alarm settings without proper assessment and authorisation.

Good system design, maintenance and staff awareness can help reduce unnecessary activations while preserving appropriate fire detection.

Maintain complete fire alarm records so building managers and maintenance engineers can understand the installation and its history.

Keep relevant documents such as:

  • System design and installation drawings
  • Equipment and device schedules
  • Commissioning and handover documentation
  • Weekly user test records
  • Professional maintenance reports
  • Fault and repair records
  • Records of unwanted alarms
  • Details of system modifications and upgrades
  • Relevant cause-and-effect information

Review your fire alarm arrangements whenever you alter the building layout, change occupancy or introduce new fire hazards.

Building changes may affect detector coverage, alarm audibility, escape arrangements or connections to other systems.

Ask a competent designer to assess significant changes before modifying the installation.

SS Systems provides maintenance documentation and can discuss suitable upgrades when your requirements change.

Choose a commercial fire alarm provider that can support your system throughout its working life, not just during the initial installation.
