Fire Alarm Installation

The installation of fire alarms in the UK is governed by British Standards, specifically BS5389. This regulation encompasses the guidelines for fire safety devices, including smoke detectors. These detectors are designed to identify the presence of smoke either through the heat emitted by smoke particles or via specific indicators engineered to recognize smoke. This early detection aims to trigger an alarm before smoke levels increase to the point of igniting an open flame.

Adhering to the BS5389 standard for fire alarm installation entails following specific guidelines regarding the placement and height of smoke detectors. It also covers the necessary electrical wiring practices for these detectors, including requirements for a battery backup system. FP Fire install all our Fire Alarms to BS5389 standards.

The Importance of Working Fire Alarms

  • Alerts occupants early, allowing for timely evacuation.
  • Helps to minimize property damage by enabling quicker firefighting response.
  • Integral to building safety systems and regulatory compliance.

Types of Fire Alarm Systems:

  • L1 Fire Alarm Systems:
    Full coverage with detectors in all areas including voids, for maximum protection.
  • L2 Fire Alarm Systems:
    High-risk area and escape route coverage, less comprehensive than L1.
  • L3 Fire Alarm Systems:
    Focuses on protecting escape routes and adjoining rooms for safe evacuation.
  • L4 Fire Alarm Systems:
    Limited to escape route detection to ensure clear evacuation paths.
  • L5 Fire Alarm Systems:
    Customized protection for specific areas or risks not covered by L1-L4.

Grade A and Grade D Fire Alarms

  • Grade A:
    These systems are typically found in larger or more complex buildings and involve a control panel, with detectors, alarms, and call points wired throughout the property. They are designed for high-risk environments such as commercial properties or larger HMOs with numerous occupants or vulnerable residents.
  • Grade D:
    This system is much simpler and more commonly used in smaller residential buildings. It consists of mains-powered smoke and heat alarms with backup battery power, installed primarily in circulation areas (such as hallways) and high-risk areas like kitchens. It’s more affordable and straightforward to install and maintain compared to a Grade A system.

Fire alarms are essential as they provide the first alert to occupants of a fire, allowing for immediate action to be taken.

Fire alarms detect fires through various sensors that can identify smoke, heat, or flames.

Fire alarms should be tested regularly, at least once a month, to ensure they are working correctly and can be relied upon in an emergency.
