By adhering to BS5839 fire alarm systems regulatory compliance and standards, organisations can ensure the effective implementation and operation of fire alarm systems. Thus promoting occupant safety, regulatory compliance and the reduction of fire-related risks.
BS5839 System Categories and Grades
The introduction of BS5839 fire alarm systems categories and grades aids when classifying a fire alarm system. For example, based on its intended purpose, we can assign performance requirements. Additionally, categories and grades help determine the level of protection needed for a specific building or premises. Here is an overview of the system categories and grades within BS5839:
- Category M Manual systems where the detection of fire is reliant on human observation. Thus, no automatic fire detection or alarm initiation.
- Category L5 Systems are designed for the protection of specific parts of the building, such as high-risk areas. Early detection is required but not throughout the entire premises.
- Category L4 Systems are designed to provide coverage in defined areas or zones. Anywhere the risk of fire is present, therefore, ensuring early detection and warning.
- Category L3 Systems are designed to provide coverage throughout all areas of the building. Ultimately, providing early detection and warning capabilities.
- Category L2 Systems are designed for life safety, covering all areas of the building. For example, we can target specific fire hazards. The aim is early detection and a quick fire evacuation.
- Category L1 Systems are designed for life safety and property protection. L1 systems provide the highest level of coverage with automatic fire detection and rapid response throughout the building.
The system grades within BS5839 determine the reliability and performance of the fire alarm system components:
- Grade A: This is the highest grade and offers the highest level of protection. Grade A systems typically have fully redundant components and multiple backup power supplies. In fact, they are designed to provide continuous monitoring and coverage throughout the premises, including detection, notification and control.
- Grade B systems provide a high level of protection, but they may not have the same level of redundancy as Grade A. Generally, these systems are designed to cover critical areas or sections of a building. Also, they are suitable for applications where a high level of protection is required, but not necessarily required throughout the premises.
- Grade C systems offer a basic level of protection. Often, they have limited coverage and will typically consist of standalone detectors and alarms. In brief, no centralised control panel. We supply these systems to smaller buildings or individual units.
- Grade D systems are used in residential buildings and offer a basic level of protection. They consist of standalone battery-powered smoke detectors that provide local alarms but are not interconnected.
It’s important to carefully assess the specific requirements and level of fire risk in a building to determine the appropriate system category and grade. Compliance with the designated category and grade ensures the implementation of a fire alarm system that meets the necessary performance and safety standards.
Fire Detection Devices and Equipment
Smoke detectors are designed to detect the presence of smoke particles in the air. They can be categorised into various types. For example, ionisation smoke detectors, photoelectric smoke detectors and multi-sensor smoke detectors. Generally, these devices are strategically placed throughout the building to provide early warning of fire.
Heat detectors are designed to sense increases in temperature and are suitable for areas where smoke detectors may not be suitable due to high levels of dust, fumes or steam. There are different types of heat detectors, such as fixed temperature heat detectors and rate-of-rise heat detectors, each with its own detection mechanism.
Flame detectors are specialised devices that detect the presence of flames through optical sensors. They are typically used in environments where fast flame detection is essential, such as areas with flammable liquids or gases.
Manual Call Points:
Manual call points are often referred to as fire alarm call points or break glass units. These devices allow individuals to manually activate the fire alarm system by breaking the glass or pressing a button. We place these products in easily accessible locations throughout the building.
Sounders and Beacons:
Sounders and beacons provide audible and visual alerts, respectively, to notify occupants of a fire alarm activation. These devices are typically installed in areas where occupants may have difficulty hearing or seeing the standard fire alarm sounders.
Control and Indicating Equipment (CIE):
CIE serves as the central control unit for the fire alarm system. The CIE receives signals from the detectors and other fire alarm system devices and controls the activation of sounders or beacons. CIEs can also provide visual indications of the system’s status and any fault conditions.
It’s important to note that BS5839 provides guidelines on the selection, installation, positioning, and maintenance of these devices and equipment to ensure their proper functioning. Compliance with these guidelines helps ensure reliable and effective fire detection within a building or premises.
In conclusion, BS5839 fire alarm systems are a comprehensive British Standard.
