Answers to Your Fire Safety Questions - FirePro UK FAQ

To quote the manufacturer's statement ‘Independent test results have proven the efficacy of the FirePro product and its ability to knock down flames, reduce temperature and control propagation of thermal runaway to prevent spread between cells’. See manufacturers letter here.

FirePro systems may be used as a key component for the protection of heritage / historical premises, as part of a fire strategy that encompasses early warning of fire and immediate reactive fire suppression to mitigate the potential for accelerated fire spread within poorly compartmented spaces, that often exist in heritage structures such as wall, floor or ceiling voids.  

Compared with traditional sprinkler and pressurised gas systems, FirePro significantly reduces embodied carbon by eliminating heavy steel tanks, cylinders, extensive pipework, hydraulic calculations, building works, and specialist installation equipment. FirePro is a simpler, lighter, modular environmentally friendly approach to fire suppression.

The independently certified lifespan of all FirePro fire suppression generators is 15 years from the date of manufacture. This lifecycle is independently tested and certificated by KIWA an accredited European test laboratory. At the life cycle expiry, the FirePro units should be returned to FireProUK for safe environmental and certificated disposal.

FirePro may be configured in a variety of options. Smaller modular self-contained in cabinet systems may operate as completely stand alone with no power supply, or alternatively a range of options follow on that require either just an internal CR2 standalone battery leading up to a monitored external power supply and standby batteries for continued operation.

The speed of a FirePro system activation is fully configurable with the desired fire detection method, and the fire engineering strategy. FireProUK can provide competent fire strategy formulation in line with client requirements.

FirePro is currently the only LPCB-approved condensed aerosol fire suppression system, demonstrating that the product meets strict independent standards for performance, reliability, and fire safety.

At the completion of the system design, the FirePro products are usually held in stock for delivery within 7-10 days. On occasions where demand outstrips immediate supply, the delivery lead time may then increase to four to six weeks from receipt of purchase order. Installation timelines may vary depending on system complexity, project scope, site requirements and resource availability.

FirePro systems require routine inspection and testing to ensure continued reliability and compliance with fire safety standards, typically carried out at least twice per year. All servicing should be performed by trained and competent personnel, ideally certified to LPS1204 3.2 or equivalent, with frequency determined by risk assessment.

A typical FirePro servicing and maintenance contract includes visual inspection of all generators and associated control equipment, functional testing of detection, alarm, and activation circuits, verification that units remain within their 15-year service life (with isolation/replacement scheduling as needed), enclosure integrity checks where applicable, and a written service report confirming system status and any remedial actions required.

As system size, unit count, and site complexity vary considerably, cost is quoted per site by your local FirePro UK Ambassador following a site visit.

Following a FirePro system discharge, when it is deemed safe to re-enter the protected area, FirePro particulate should be immediately ventilated to fresh air via extraction systems or natural ventilation. All reinstatement work should be carried out by suitably competent fire protection professionals to ensure system compliance.

Occupant safety is central to every FirePro application. When correctly designed, installed, commissioned, handed over and operated by suitably competent persons, in accordance with manufacturer product guidance, applicable standards and local codes of practice, FirePro may be considered a safe and effective fire suppression solution. As required by BS EN 15276, any exposure to the discharged agent should be kept to the minimum necessary, supported by appropriate warning, evacuation, and re-entry procedures.

Protectionism. FirePro is a proven, innovative fire suppression technology that challenges traditional approaches. Like any disruptive solution, it can attract negative claims from competitors protecting legacy systems. The facts are clear: FirePro is independently tested, internationally certified, and increasingly adopted across demanding fire risk applications where performance, simplicity, sustainability, and value matter.

Our role is not simply to supply the product, but to help clients, specifiers, insurers, installers, and end users make informed decisions based on risk, compliance, performance, sustainability, and long-term value. Where FirePro is the right solution, we will explain why; where it is not, we will say so. That commitment to integrity, evidence-based guidance, and practical fire safety outcomes is central to everything FirePro UK delivers.

FirePro condensed aerosol technology interrupts the chemical chain reaction of combustion at a molecular level, without significantly depleting oxygen or increasing pressure in the protected space. This gives FirePro several practical advantages over legacy agents:

• No pipework or pressurised cylinders — unlike gaseous systems, FirePro units are self-contained, reducing installation complexity, cost, and maintenance.
‍
• No water damage — unlike sprinklers, FirePro leaves no residue that damages sensitive equipment, making it ideal for electrical, data, and archival environments.
‍
• Environmentally friendly — no CFCs, HCFCs, HFCs or PFAS, zero Ozone Depletion Potential and zero Global Warming Potential.
‍
• Tolerant of room leakage — up to 0.17%, compared with the 0.1% maximum typically specified under BS EN 15276 for pressurised gas systems.
‍
• 15-year lifespan — units are simply isolated, disconnected, and replaced at end of life, with no recharging or agent disposal required.

For more on how the technology works, see our Condesened Aerosol Technology page.

FirePro offers a product range of ATEX-certified for use in explosive environments containing flammable gases, vapours, or combustible dust, such as oil and gas facilities, chemical plants, and industrial sites. Please see the technical prospectus here.

FirePro fire suppression systems must always be designed by those that can evidence suitable competency. In the UK & Ireland, FireProUK provide manufacturers product training at individual level and provide a 24-month license technical support. To see a list of specialist installers that will assist with system design, click here.

FirePro fire suppression generators are supplied with a 3-year manufacturer-backed warranty from the point of sale, ensuring product reliability and performance.

FirePro generators may be installed locally in cabinet or typically at high level, such as on walls or ceilings, for total flood systems. This simplifies building services co-ordination whilst minimising disruption and maintaining a discreet installation profile.

FirePro fire suppression systems may be interfaced to an existing fire alarm or BMS system via clean volt free change over contacts, that will operate in accordance with the desired fire engineering strategy.

FirePro holds a comprehensive range of international certifications and approvals, including UL, ULC, BSI, VdS, LPCB, KIWA, and ISO standards, ensuring compliance with global fire safety regulations. See all product certification page here.

The applicable standards for condensed aerosol fire suppression systems are BS EN 15276 and ISO 15779, which define the design, installation, testing, and performance requirements for aerosol-based fire protection systems.

The cost of a FirePro fire suppression system depends on factors such as enclosure size, and project requirements. Our approved FirePro ambassadors cover the length and breadth of the UK & Ireland. They are our installation experts and will provide competitive quotations for the design, installation, commissioning, handover and maintenance of a bespoke FirePro solution to protect your fire risk.

Unlike traditional gas suppression systems, door fan testing is not a mandatory annual requirement under BS EN 15276, however, in the event of any uncertainty regarding enclosure integrity and the potential for agent dilution or leakage, it is strongly recommended that a door fan test is undertaken by a suitably competent person, as ensuring adequate enclosure sealing is still important for optimal fire suppression performance. Read more about Leakage Prevention System (LPS).

The speed of FirePro redeployment will be dictated by the availability of suitably competent resource to remove the spent units and install new. FirePro UK normally carry an extensive stock inventory however, to mitigate any potential delay in the supply of replacement materials, it is strongly advised that an inventory of spare units is held on site.

The first consideration for FirePro is to deliver the intended outcome, namely, to suppress fire. The particulate is non-corrosive at the time of discharge. Dependent on ambient temperature and humidity, the particulate will form a residue that may be cleaned, however, the longer it is left the more the moisture absorption will occur, therefore time is of the essence. As soon as it is safe to re-enter the enclosure the particulate should be ventilated to fresh air via dedicated or natural ventilation. The manufacturer provides very clear cleaning management instructions within the product manual, available on request from FireProUK.

FirePro may only be considered for use with sensitive electronic equipment, when used as a component within a well-structured and informed risk assessed fire engineering strategy. This requires (via disclaimer) acceptance of the risk of irreparable damage, caused by particulate exposure. When fire occurs, sensitive equipment is exposed to the products of combustion, this alone may cause irreparable damage.

Exposure to water-based suppression may also create the same risk, potential for flood damage, or at best, withdrawal of product warranties. As a dry chemical system, FirePro avoids this. The alternate fire strategy for consideration requires the installation of aspirating fire detection (which will provide early warning up to 30 times faster than conventional point detection), which will buy time for investigation and appropriate action as required at the time, which may be isolation of power, use of a portable fire extinguisher (where safe), or just retain a watchful eye to monitor stability.

If a serious fire is confirmed, suitably trained personnel may manually activate / release FirePro, all in accordance with site specific SOPs. The intention of the strategy is A) manually intervene to manage an event and take corrective action, early, B) avoid unnecessary suppression system discharge and resulting cost / disruption for re-instatement, when the event may have been avoided, and C) provide manual and automatic fire suppression system cover, as the required back stop. 

If you hear concerns or receive conflicting claims about FirePro or any fire suppression technology, ask for the evidence behind those claims and seek clarification from FirePro UK or a certified FirePro installer. We will review the information openly, provide evidence-based technical guidance, and help ensure decisions are based on accurate, balanced, and application-specific advice.
