Detect Smoke Early and Act Accordingly

    Using our Very Early Smoke Detection Apparatus (VESDA) you can be alerted to the presence of a fire or potential fire before it fully develops.

    VESDA works by continually analysing the air inside your commercial premises, identifying any changes which may indicate the presence or potential for a fire.

    The Benefits of Air Sampling Systems

    Air sampling is one of the most advanced means of fire detection, helping you to react before an incident becomes costly.

    Different Types of Sampling System

    We work with a variety of VESDA systems, including: Warehouse, Gas Detection, Elevator Shaft Protection and Addressable Aspiring. 

    Maintenance, Servicing and Support

    The Benefits of VESDA Systems

    Early detection is crucial in minimising the impact of a fire to your business and, most importantly, human life. VESDA can be used in almost any application, but there are a few specific reasons why they offer a better solution to traditional spot detectors.

    Early detection is crucial in minimising the impact of a fire to your business and, most importantly, human life. The sooner a fire is detected, the sooner emergency protocol can be activated and emergency responders can attend the scene and react accordingly.
    VESDA is useful in environmentally challenging areas where smoke is difficult to detect, like wind tunnels and very hot environments. Dust can also clog the receptors of a traditional alarm. VESDA systems are designed with pipe purging systems to reduce this risk.
    VESDA systems are ideal for buildings that require concealed detection, whether for aesthetic or practicality. Detectors can be installed into the aesthetic of a property without compromising sensor effectiveness, keeping style and safety at the forefront.

    In a lot of scenarios, unnecessary pressure released from suppression systems or extinguishers can cause serious damage - particularly in environments housing electrical infrastructure or important documents. VESDA alerts a responder to environmental changes immediately, helping them to react before an agent is released. 

    VESDA systems are useful for businesses which are in need of a very early warning to smoke or the possibility of fire. For instance, museums with high value assets or hospitals/residential homes which need suitable time to evacuate patients who lack mobility.
    Addressable aspirating VESDA Systems

    Addressable Aspiring Systems

    The addressable aspirating system works by using multiple air sampling points located around your premises, with each point pulling air back through the system via a network of piping. The air is then sampled through the aspiring smoke detector and analysed. If smoke is detected, this information is relayed to the control panel and an alarm is triggered, giving you the precise location and allowing you to act quickly and effectively.

    • Can be deployed in a wide range of different applications.
    • Multi-port addressability.
    • Unparalleled connectivity and expansion opportunities.
    • Field upgradability.

    Warehouse VESDA system installers

    Warehouse (Industrial) Systems

    The VESDA Laser Industrial Aspirating Smoke Detector system is ideal for use in industrial applications and harsh environments, supporting everything from warehouses to mines, and even livestock/animal facilities. The VLI detector combines a fail-safe Intelligent Filter (patent pending) with an advanced clean-air barrier for optics protection, enabling absolute detection and a long detection chamber life, without the need for re-calibration.

    • Can be applied to an enormous amount of applications.
    • Suitable for Class 1 Division 2 applications- Groups A,B,C, & D.
    • Up to 2000 m2.
    • Five relays (fire, fault, and 3 configurable).

    Gas detection vesda systems

    Gas Detection Systems

    Invisible hazards can originate from the release of combustible gases/vapours. VESDA ECO (Ex) uses an existing VESDA pipe network to actively sample air for the presence of these flammable gas/vapours (alcohols), protecting personnel and property whilst ensuring business continuity. This product must be used in conjunction with an existing VESDA system but is suitable for use in almost every environment.

    • Does not require major retrofitting as it leverages existing systems.
    • Provides non-intrusive detection.
    • Approved for Class 1 Div 2 applications.
    • Enables centralised monitoring and communication with building systems for real-time awareness.

    Elevator shaft vesda systems

    Elevator Shaft Protection

    VESDA ASDs work by actively drawing air through sampling holes in a network of pipes that are installed along the elevator shaft and in the elevator machine room. The sampling pipe is connected to a detector with a powerful aspirator that draws the air into a detection chamber to analyse for the presence of smoke.

    • Can be connected to a building management system via an existing fire alarm control panel or operate independently to provide alarm information.
    • Placed outside the machine room and in shafts to ensure the detector is always accessible for testing and maintenance.
    • The sampling holes are typically located at the top of the elevator shaft. In tall buildings, the pipe runs down the shaft vertically to ensure sampling at multiple levels.

    Servicing & Maintenance

    To maintain VESDA systems at optimal performance levels, building owners are advised to schedule regular maintenance and servicing visits through a dedicated provider. The frequency of this servicing will depend on the application. For example, factories or settings with high vehicular traffic will require more frequent servicing since they commonly have higher levels of pollution.
