Fire Detection Systems
A fire detection system (FDS) is an alarm system that receives data on, assesses and then responds to events reported by various fire detectors. Fire detection systems are permanently installed manual and automatic systems to detect fires at an early stage, warn those affected and quickly inform the relevant emergency service.
Equity Fire Solutions - Fire detection systems are mostly installed in buildings particularly at risk such as airports, train stations, universities, schools, business and factory premises, residential homes for the elderly and hospitals. The building permit issued by the building inspectorate or the insurance cover specified by the South African Inspectorate for Fire Protection states whether there is an obligation to install a fire detection system connected to the fire brigade.
Design and operation of a fire detection system
Equity Fire Solutions Schema fire alarm addressable system wiring diagram pdf New System Sensor Smoke Detector Wiring Diagram Simple System Sensor All parts of the building to be monitored are equipped with a network of electric cables and automatic/non-automatic detectors. These detectors are operated either manually or triggered automatically by heat, visible or invisible smoke, or flames.
Only the detectors in the immediate vicinity of the fire are activated, sending a report to the fire detection control panel. From here, the information can be forwarded to a permanently manned unit and/or the fire brigade. Those affected are also warned. Once the fire has been extinguished, the system can be made operational again quickly and simply.
System Design
Before starting, the designer will need to ensure that certain information is available. This may be given in the specification or it may have to be obtained by consultation. As well as the purchaser, there may be a requirement to consult with other interested parties

    The Importance of Fire Safety Equipment Maintenance As the owner of a commercial property, be it as an employer, landlord, or occupier of a non‐domestic premises, you are responsible for ensuring your building meets fire safety standards.
    Fire Safety Equipment Maintenance
    As set out in the SANS 1475: 1&2, a ‘responsible person’ ‐ be it yourself or a nominated “competent” person ‐ must carry out a fire risk assessment to assess any fire hazards within the building, and take the necessary actions to reduce any fire risks and ensure all fire safety equipment is maintained at all times.
    In this article, we discuss the importance of keeping fire safety equipment in perfect working order at all times.
    Equipment Checks
    It is essential that you have fire safety equipment in place in your commercial property, positioned in accessible locations should there ever be a fire.
    Both passive and active fire safety equipment should be regularly checked for any signs of wear or damage, in order to ensure they are working correctly at all times.

    Equipment checks can include:

    Fire Doors: Ensuring fire doors are operating correctly and can be shut without obstruction on a daily basis.

    Fire alarm testing: A weekly fire alarm test (on the same day and at the same time is best practice in order that employees and visitors to your site are aware that a test is being conducted).

    Get testing: Regular monthly testing of emergency lighting systems, fire extinguishers.

    Test all equipment: Any additional fire safety equipment in place such as fire blankets or sprinkler systems should also be tested.

    Everything You Need to Know About Fire Extinguishers

    Fire extinguishers are an essential piece of fire safety equipment every premises is required to have. In order to ensure you have the correct fire extinguishers for your building, it is important to know the different options available, and which you are most likely to need.

    Fire Extinguisher Classifications

    A fire extinguisher is classified depending on the type of fire it is designed to put out ‐ fires are categorized by classes.
  • Class A Extinguisher‐ These extinguishers are suited for use on freely burning carbonaceous materials such as wood, paper and fabrics.
  • Class B Extinguisher ‐ For use on flammable liquid fires, such as oil, petrol and diesel
  • Electrical Extinguisher ‐ Meant for use on electrical fires. Can also be used on flammable liquids
  • Class C Extinguisher ‐ For use on Gaseous fires such as propane and butane.
  • Class D Extinguisher ‐ A specialist extinguisher for use on combustible metals such as Potassium, Sodium and Magnesium.
  • Class F Extinguisher – A specialist extinguisher for Deep Fat Fryers which use cooking oils.

    Multi-Class Ratings

    For added convenience, many extinguishers that are currently available can be used on multiple fire types, so will be marked with more than one classification.

    How Fire Extinguishers Work

    Fire extinguishers operate by affecting what is known as “the Fire Triangle” – the term used to describe the three essential components required for a fire to exist, these are FUEL, HEAT and OXYGEN.

    4 Types of Extinguishers

    Different extinguishers remove at least one of these three components, thus extinguishing the fire:

    Dry Powder
    This type of extinguisher is usually rated for multiple purpose use (Class A, Class B, Class C and electrical fires), although their use indoors is not recommended.

    These contain a powder based extinguishing agent, this smothers the fire removing oxygen and alters its chemical composition.

    Water
    Suitable only for use on Class A fires (freely burning carbonaceous materials such as wood, paper and fabrics).

    These extinguishers contain water (and sometimes a special additive) and these cause rapid cooling, reducing heat from the fire.

    Foam
    Suitable for use on Class A and Class B fires (freely burning carbonaceous materials such as wood, paper and fabrics and flammable liquids).

    These extinguishers are water based with a special additive and these cause rapid cooling, reducing heat from the fire, but the special foam additive also removes oxygen too.

    Carbon Dioxide Primarily designed for use on electrical fires, but suitable for use on flammable liquids fires, these displace oxygen, reducing levels to an extent where a flame cannot be sustained.

    How to use a Fire Extinguisher


    Modern extinguishers operate on a simple “seize and squeeze” method of operation. An easy way to remember this is with the acronym PASS which describes the four stages:
    Pull
    Pull out the safety pin from the operating levers/handle that prevents the extinguisher being accidentally discharged. There may also be a tamper evident seal fitted to the extinguisher; these are designed to break very easily as the safety pin is removed.
    Aim
    Aim the nozzle/discharge horn of the fire extinguisher at the base of the fire.
    Squeeze
    Completely squeeze the operating levers/handle in order to discharge the extinguisher, ensuring you are the appropriate distance from the fire.
    Sweep
    Sweep the nozzle/discharge horn back and forth at the base of the fire to ensure it is extinguished. Be sure to keep going until the extinguisher is empty to avoid recognition.
    *For Class F extinguishers (cooking oils), completely discharge the extinguisher into the deep fat fryer from a minimum 1m distance away, with the lance held directly above the burning oil.

    Fires Safety Signs
    Here at Equity Fire Solutions, we provide a comprehensive range of fire safety signs for our customers. With years of experience in the industry, we can advise our customers on their entire fire safety strategy, including the crucial aspect of signage. Current legislation and regulations expect responsible persons to communicate vital safety information to employees, visitors, contractors and anyone that is likely to use their building. Fire safety signs are a cost-effective way of complying with this requirement.

    The legislation requires that a formal risk assessment be carried out and this will determine the need for safety signs to locate and identify means of escape routes and lifesaving equipment. Best practice recommends that an audit and review should be carried out to determine the residual risk associated with using a safety sign of poor non-conforming design. It is a recommendation that a plan is drawn up for their replacement.

    We can assist by auditing your site to include:
  • MEANS OF ESCAPE ROUTE IDENTIFICATION
  • FIRE ACTION NOTICES
  • MANDATORY FIRE DOOR NOTICES
  • EMERGENCY DOOR OPENING DEVICE IDENTIFICATION
  • FIRE-FIGHTING EQUIPMENT LOCATION AND IDENTIFICATION

  • Fire Hydrant Valves
    A Fire Hydrant Valve is a pipe fitting that help to regulate, direct or control the flow of fire suppressing agents by opening, closing or partially obstructing passageways in the hose connectors. Non-return valves stop the fire suppressing agent from flowing in the wrong direction.

    With the hose attached to the fire hydrant, the valve can be opened to provide a powerful flow of water to extinguish a fire. Fire hydrant valves provides access to water supply for the purpose of fighting fires. The water supply may be pressurized or un-pressurized. Every hydrant has one or more outlet to which a hose may be connected.

    Most fire hydrant valves are not designed to throttle the water flow; they are designed to be operated full-on or full-off. The arrangement of most dry-barrel hydrants is for the drain valve to be open at anything other than full operation. Usage at partial-opening can consequently result in considerable flow directly into the soil surrounding the hydrant, which, over time, can cause severe scouring. Where a hose has a closed nozzle valve, or connects to a fire truck or closed gate valve, one must always attach the hose to the hydrant before opening the hydrant's main valve.
    There are 5 different types of valves to choose from, see their specifications:
  • Right Angle 80mm Brass
  • Right Angle, tamper proof – 80mm Brass
  • Right Angle 80mm – Cast Iron & Adaptor
  • Upward Oblique 80mm Brass
