A fire detection system is a network of sensors and devices designed to detect and alert people to fire in an area or a building. Frontline Safety's Fixed Gas and Fire Project Team can build a system to suit the specifics of your workplace. These typically include smoke detectors, heat detectors and alarms that can be activated manually or automatically.
A typical scenario may comprise a control panel, several conventional smoke detectors, linear heat detection cables, sounders and alarm systems. A conventional smoke detector can be interconnected with several other detectors to pick up smoke and trigger an alarm. Depending on your application and type of building, Frontline Safety can provide conventional or addressable alarm systems. We have experience providing these for industrial and large commercial applications, from office and administration buildings to pharmaceutical and petrochemical processing plants.
Fire protection systems refer to a set of measures and equipment designed to prevent and manage fire disasters. These systems are installed in buildings, factories, and other facilities to protect people and property from fire damage. Some common fire protection systems include fire alarms, sprinkler systems, fire extinguishers, smoke detectors, and fire suppression systems (see below for more information). Overall, fire protection systems are essential for ensuring people's and property's safety during a fire. By quickly detecting and suppressing fires, these systems can help prevent the loss of life and property damage from a fire. Our team are experts in their field and are trained in supplying and installing some of the industry's biggest fire detection and protection providers.

Conventional fire alarm systems can be used in buildings split into zones. Each conventional alarm will be connected to a specific circuit, and if an alarm triggers in one zone, the corresponding circuit is activated, and an alarm sounds.
Addressable fire alarm systems pinpoint the precise location of a fire, or a fault, as each device has a unique address. An addressable alarm system's advantage is quicker identification and response to a fire or fault
Audible and visual warning devices are available for both Conventional and Addressable alarm systems. Several options exist for audible and visual alarms, from traditional alarm bells to space-saving integrated base units and wide area high output alarm devices for areas with high ambient background noise. Combined sounder/beacon warning devices are available in conventional or addressable options, and warning beacons can be provided per EN54 - 23 design codes for Visual Alarm Devices (VAD’s).
Linear heat detection cables accompany fire detection systems. They detect fire in areas where traditional smoke detectors, such as a humid or dusty environment, may not be suitable. The material they are made of is heat-sensitive, and they can be installed along walls, ceilings and other surfaces to provide continuous fire protection.
For high-risk environments, an aspirating detection system (ASD) would be beneficial. A network of pipes is designed to draw air samples from a protected area through a pump and detect smoke or other combustible gases. A significant advantage of an ASD is the early detection of a fire, which would be critical in applications such as chemical storage facilities, confined spaces and mining, to name a few.
The highly sensitive nature of these systems allows smoke to be detected before it's even visible. They're often set up through a central detection unit, such as an air conditioning unit, and can sometimes simultaneously detect gas. Alarm systems are to be configured to sound multiple alarms depending on the fire or gas leak status. These can be networked to suppression systems, such as gas, foam or water
The placement of detection instrumentation is crucial to effectively operating fire and gas systems. Fire and gas mapping is a process commonly used in the oil and gas industry, which helps to identify potential fire and explosion hazards. During the procedure, our team can help identify the impact of the placement of your detection system and use it to mitigate any risks. This whole process can assist with the design of your system and integration into your environment.
Frontline Safety can offer hydraulic calculations using specialist software programmes to assist with large and complex installations. Such programmes also allow the identification of any weaknesses in the design. Carrying out a Hydraulic Calculation will verify and validate the design and demonstrate that the system shall provide both sufficient volume and pressure to achieve the fire suppression goals.
Suppression systems are fire protection systems that use agents such as foam, water or chemicals (like gas) to suppress or extinguish fires. A suppression system is beneficial for applications where traditional water sprinkler systems, such as data information centres, telecommunication rooms and areas with electrical cabinets, cannot be used. Frontline Safety can offer bespoke systems, and our team of project engineers will be able to engineer a solution for you and your application.
Gas Suppression Systems
A gas suppression system is a type of fire suppression system that uses inert gases or chemicals to extinguish fires. Unlike traditional water-based fire suppression systems, which can damage sensitive equipment, gas suppression systems quickly and effectively extinguish fires while minimizing damage to the protected area and its contents.The system works by detecting a fire using smoke or heat detectors. Once a fire is detected, the gas suppression system will release a predetermined amount of gas into the protected area. The gas works by reducing the oxygen concentration in the air to a level where combustion can no longer occur. This quickly extinguishes the fire without causing harm to people or property.Gas suppression systems are commonly used in areas where traditional fire suppression systems are unsuitable, such as data centres, museums, and hospitals. They are also used in areas where immediate evacuation is not feasible, such asunderground tunnels or storage facilities. A gas suppression system is a safe, effective and reliable way to protect people and property from fires.
What type of Gas Suppression Systems are available?
INERT GAS - Removes oxygen from the fireInert Gas fire suppression systems, sometimes called "Clean Agent" systems, use naturally occurring gases (predominantly Nitrogen and Argon) to reduce Oxygen levels within a protected space to such an extent that the atmosphere no longer supports combustion. A popular choice for inert gas fire suppression systems is IG55, a 50% Argon / 50% Nitrogen mix. IG55 is a clean, odourless, and electrically non-conductive gas ideal for use in areas containing sensitive electrical/electronic equipment. Inert gas systems can be considered an environmentally responsible choice for fire suppression systems as IG55 has zero Ozone depletion and zero global warming potential and leaves no residue that would necessitate an extensive post-discharge clean-up operation.Typical applications include computer, telecommunication and switchgear rooms and electrical cabinets.
HALOCARBON GASES - prevent the chemical reaction of combustion from occurringUsing Halocarbon Gases as a suppression system can prevent the chemical reaction of combustion from occurring. Fast extinguishing flames through Halocarbon Gas is crucial, but this is also costly compared to other suppression systems.Typical applications include computer, telecommunication and switchgear rooms and electrical cabinets.CARBON DIOXIDE (CO2) - removes Oxygen from the fireCarbon Dioxide (CO2) has a density greater than air, so it can suppress a fire by removing the Oxygen (O2) a fire requires to burn. This suppression system can be used as a 'local system,' meaning it will apply CO2 directly onto whatever is burning. Something to note with this system is that carbon dioxide cannot be used when personnel are present. However, we can ensure several safeguarding measures are used to prevent accidental discharge when these spaces are occupied.Typical applications include unoccupied electrical switchgear rooms, gas turbines and machinery space.HYPOXIC SYSTEM remove Oxygen from the protected space to prevent combustion from occurringA Hypoxic system works to remove oxygen from a protected area to prevent combustion from occurring. This system is commonly seen in applications such as libraries or archive stores and can be used whilst allowing personnel to continue working inthe room without any health risks. Typical applications include libraries and archive stores.
Foam suppression systems effectively suppress fires and smother the flames, preventing Oxygen (O2) from reaching them. They are commonly used in industrial settings where flammable liquids, such as hydrocarbon fuels, may be at risk of catching fire. One of the benefits of a foam suppression system is that it can cover large areas quickly due to its expansion properties. There are different types of foam suitable for specific flammable properties, which our team can help to explain once your needs are communicated.
A water suppression system comprises small water droplets to create a mist. These mists simultaneously cool fire and reduce the Oxygen to prevent combustion from occurring. The water mist can be carried through a network of pipes, valves and sprinkler heads placed throughout a building or facility. The water is released onto the affected area to extinguish the flames. An advantage of water mist suppression over a traditional sprinkler system is can reach an increased surface area. It's mostly suitable for applications involving machinery, power generation turbines and transportation.
