Yes. Compatibility is critical when expanding or upgrading fire alarm systems.

We can advise on compatible:

• Fire alarm panels
• Detectors
• Sounders
• Call points
• Interfaces
• Power supplies
• Emergency lighting systems

Yes. Compatibility is critical when extending or upgrading existing fire alarm systems.

We can assist with compatibility advice for:

• Addressable panels
• Conventional panels
• Smoke detectors
• Heat detectors
• Interfaces
• Sounders
• Loop devices
• Power supplies

Conventional systems divide buildings into zones and identify alarm locations by area.

Addressable systems identify the exact device in alarm or fault condition, making them better suited for larger or more complex sites.

Addressable systems also provide greater flexibility for monitoring and diagnostics.

Yes. We supply wireless and hybrid fire alarm solutions suitable for applications where cabling is difficult or disruptive.

Wireless systems are commonly used in:

• Heritage buildings
• Listed buildings
• Occupied premises
• Temporary installations
• Refurbishment projects

Wireless fire alarm devices are commonly approved to EN54-25, the European standard covering radio communication equipment used within fire alarm systems.

Aspirating smoke detection (ASD) systems actively sample air through pipe networks to detect smoke particles at a very early stage.

They are commonly used in:

• Data centres
• Clean rooms
• Archives
• Telecoms rooms
• Critical infrastructure

Fire alarm systems should normally be tested weekly in accordance with UK fire safety recommendations and relevant standards such as BS 5839.

Routine servicing and maintenance should also be carried out by competent professionals.

We supply a wide range of leading fire detection and life safety manufacturers including:

• Apollo
• Hochiki
• Kentec
• Advanced
• C-TEC
• EMS
• Fike
• Gent
• Hyfire
• Morley
• Notifier

BS 5839 is the British Standard covering fire detection and fire alarm systems for buildings in the UK.

BS 5839-1 applies to commercial and non-domestic buildings, including offices, schools, hospitals, industrial premises and public buildings.

BS 5839-6 applies to domestic properties, including dwellings, flats and HMOs (Houses in Multiple Occupation).

The standards provide guidance on system design, installation, commissioning, maintenance and ongoing testing.

Yes. Wireless fire alarm systems can comply with UK standards when correctly specified, installed and maintained.

Wireless fire alarm devices are commonly approved to EN54-25, the European standard covering radio communication equipment used within fire alarm systems.

System suitability depends on the application, building requirements and correct system design.

EN54 standards are European product standards used for fire detection and fire alarm system components.

Each product used within a fire alarm system must comply with the relevant EN54 standard for its device type and function.

Common EN54 standards include:

• EN54-1 – Introduction
• EN54-2 – Control and Indicating Equipment (CIE)
• EN54-3 – Fire Alarm Devices – Sounders
• EN54-4 – Power Supply Equipment
• EN54-5 – Heat Detectors – Point Detectors
• EN54-7 – Smoke Detectors – Point Detectors Using Scattered Light, Transmitted Light or Ionization
• EN54-10 – Flame Detectors – Point Detectors
• EN54-11 – Manual Call Points
• EN54-12 – Smoke Detectors – Line Detectors Using an Optical Light Beam
• EN54-13 – Compatibility Assessment of System Components
• EN54-16 – Voice Alarm Control and Indicating Equipment
• EN54-17 – Short-Circuit Isolators
• EN54-18 – Input / Output Devices
• EN54-20 – Aspirating Smoke Detectors
• EN54-21 – Alarm Transmission and Fault Warning Routing Equipment
• EN54-22 – Resettable Line-Type Heat Detectors
• EN54-23 – Visual Alarm Devices
• EN54-24 – Loudspeakers for Voice Alarm Systems
• EN54-25 – Components Using Radio Links
• EN54-26 – Carbon Monoxide Detectors – Point Detectors
• EN54-27 – Duct Smoke Detectors
• EN54-28 – Non-Resettable Line-Type Heat Detectors
• EN54-29 – Multi-Sensor Fire Detectors Using Smoke and Heat Sensors
• EN54-30 – Multi-Sensor Fire Detectors Using Carbon Monoxide and Heat Sensors
• EN54-31 – Multi-Sensor Fire Detectors Using Smoke, Carbon Monoxide and Optional Heat Sensors

For example, the Apollo XP95 smoke detector, one of the most widely used smoke detectors in the UK fire industry, complies with EN54-7 for point smoke detectors using scattered light, transmitted light or ionisation technology.

CE marking, CPR (Construction Products Regulation), and the Declaration of Performance (DoP) are fundamental requirements that ensure fire alarm systems placed on the market are safe, reliable, and compliant with European standards. CE marking indicates that a product meets all applicable EU safety, health, and environmental protection requirements, while CPR specifically governs construction products, such as fire detection and alarm equipment, ensuring they are tested and assessed against harmonised standards. The DoP then provides clear, documented evidence of a product’s performance characteristics, giving installers and specifiers full transparency on how it will perform in real-world conditions. Together, these elements are essential in the fire industry, not only for legal compliance but also to guarantee that systems will operate correctly when it matters most, helping to protect life and property.
