• ASPIRATING SMOKE DETECTION

    This type of smoke detection was originally used for high sensitivity environments such as data centres, but is, in fact, suitable for a wide variety of applications and for different reasons.

    Aspirating Smoke Detectors (ASD) are ideal if you need very early warning, enhanced smoke sensitivity, or as an alternative to point or beam smoke detectors.

    There are specific industry guidelines in the FIA Code of Practice for Design, Installation, Commissioning and Maintenance of Aspirating Smoke Detector Systems.

    The code also refers to the common motivators for using ASD, such as extreme environments, restricted or difficult access, and exceptional ceiling heights and heat barriers. Other reasons include aesthetics, risk of mechanical damage, anti-vandal systems and hazardous environments.



    There is a means to define any ASD system encompassing all the essential elements in such a way that any individual system can be described in a single unambiguous phrase. The definition takes into account:

    • Class of the detector (Class A – Very High Sensitivity, Class B – Enhanced Sensitivity, Class C – Normal Sensitivity)
    • Type or method of sampling (e.g. primary or secondary sampling)
    • Compliance route (either prescriptive or performance based)
    • Prime motivators for using an ASD system

    An example of such statements is:

    • Class A detector providing primary sampling for Very Early Warning to meet Test E.2

    We’re experienced in the use and application of ASD systems.

    Somerset House

    Somerset House is a heritage property dating back to 1547 in the heart of London. Although it is well known for it’s outdoor skating rink at Christmas and open air concerts in the summer, it has many other uses and accommodates many other tenants. It hosts the UK’s largest creative community working globally across art, technology, business and social enterprise.

    The South Wing of Somerset House had a mix of hard wired fire detection system, an obsolete radio / wireless fire detection system and many aspiration systems, most no longeroperational. The project was to replace all of the systems in the South Wing with a single fire detection system for all areas and provide graphical representation of this wing and two other wings with legacy systems on a single graphics platform.

    This was all to be carried out within a listed building with mixed use and different tenants with minimal disruption to day to day operations.

    Castle Mall

    Located in the centre of Norwich City, Castle Mall shopping centre comprises of 60 stores and food outlets, across five levels of retail and leisure, including an 8-screen Vue cinema. The centre also boasts a 790 space multi-storey car park.

    The fire detection and alarm system installed in the shopping centre was a Honeywell FC90 system, which was closed protocol and had reached the end of its working life. A replacement system was therefore needed to provide a modern supportable system for the shopping centre.

    This is a working shopping centre so minimal disruption to the operation of the shopping centre, retailers and shoppers was of paramount importance.

    Uniper Enfield

    Uniper’s portfolio combines large-scale power generation and management of energy supply chains. Uniper’s former parent company was E.ON, who now focus on the new energy world.

    Uniper Power Station in Enfield had fire, suppression and voice alarm systems that had reached the end of their serviceable life.  They needed modern control equipment which would combine controls for different extinguishing systems into a centralised control station.  The extinguishing systems themselves also needed replacing or updating.

    Senseco were chosen to provide a bespoke solution providing controls and upgrades for gas extinguishing, water mist and deluge systems along with a replacement voice alarm rack.  Our power station expertise and ability to provide flexible, custom built solutions to meet Uniper’s needs were key to the project.
