    Room Integrity Testing

    A gaseous fire suppression system is a highly effective and proven method of protecting your premises from fire.

    To ensure it works properly, however, it is important that room integrity testing is carried out when the system is first commissioned and at least once a year thereafter, to fully comply with BS EN 15004.

    Room integrity testing checks whether the room or enclosure where the fire suppression system has been installed is adequately sealed. If a room is inadequately sealed this can allow the fire suppression agent to dissipate too quickly, before it has time to cool or extinguish the fire. If the room is sealed too tightly on the other hand, the gaseous fire suppressant could actually cause internal structural damage to the enclosure when activated, so it’s important to ensure that the integrity of the room is adequate.

    Room Integrity testing

    At Aspect Fire Solutions, we include full room integrity testing whenever we design or install a new system. Not only does this give you peace of mind that in the event of a fire, the fire suppression system will help to contain the fire within a room or enclosure but that the risk of the fire re-igniting is minimised. To guarantee the performance of the system, it has to be checked and serviced regularly, which is why we recommend you include room integrity testing as part of an annual maintenance and service package.

    BS EN 15004 compliance

    BS EN 15004 states that any enclosure protected by a gaseous fire suppression system must have a room integrity test carried out annually. This also applies if alterations are made to a room after the system has been installed, such as when holes are drilled for new cabling, a new door is fitted, or anything else is done that is likely to affect the structural integrity of the room.

    At Aspect Fire Solutions, we provide room integrity testing for a wide range of fire suppression systems, whether it is for a system already in place or a completely new installation. Our experienced technicians aim to cause the minimum amount of disruption and in most cases, there is no need to shut down office computers or other equipment while the room integrity testing is carried out. If you want to find out more about fire suppression systems and room integrity testing, or simply need some expert advice, we’d be delighted to help. For more information please contact our local office. You can reach our northern office on 01457 875 605 and our southern office on 0845 0540 518.

      Water Mist Systems

      Water Mist is defined within NFPA 750 as a water spray where 99% of the water produced is distributed by droplets that are smaller than 1000 microns in diameter at the required design pressure at the water mist discharge nozzle.

      Systems are typically categorised into high and low pressure. High pressure systems are defined as those which will operate at pressures greater than 35 bar, but typically from 70 – 130 bar. Low pressure systems typically operate at pressures up to 12 bar.

      Both system types can be provided as either wet pipe or deluge systems. Wet pipe systems will operate in the same way as a standard sprinkler system utilising nozzles that incorporate a frangible bulb element that will rupture and activate the system once the pre-determined temperature is reached. Deluge or dry pipe systems will typically operate from electronic detection systems which will then provide a signal to activate a cylinder valve or pump.

      droplet chart

      The two main mechanisms employed by water mist for the control and extinguishment of fire are by vapour generation and surface cooling of the fire itself. When water vaporises it displaces air to over 1,600 times its original volume, thereby depleting Oxygen within the protected enclosure or local to the fire. As the water mist droplets are smaller in diameter than conventional sprinkler droplets they present a greater surface area for cooling the surface of the fire which therefore absorbs heat faster. The table below demonstrates the surface area available in relation to droplet size.

      efficiency

      Consequently, water mist systems will extinguish a fire by improved cooling and blockage of radiant heat but with reduced water demand when compared to traditional sprinkler systems.

      High Pressure

      High pressure water mist systems are supplied either as cylinder systems or with a high pressure pump assembly and storage tank. The type of system supplied will be dictated by the coverage area required and the required run time of the agent.

      High pressure systems are suitable for use on either Class A or Class B fires although the mechanism for the control and extinguishment of the fire will vary depending on the risk.

      Tube and fittings utilised on high pressure systems are 316L stainless steel.

      Low Pressure

      Low pressure water mist systems are supplied with a pump assembly and break tank. As with high pressure systems, low pressure systems can be utilised on both Class A and Class B fires but are typically employed as an alternative to conventional sprinkler systems where water storage is difficult.

      low-pressure-systems

      As less water is used when compared to standard sprinkler systems, the low pressure mist distribution pipework is also of a smaller bore than sprinkler pipework, thereby facilitating an easier installation. All tube and fittings employed on a low pressure mist system are corrosion resistant in nature, such as galvanised or stainless steel.

      The ULF Aquamist nozzles AM27 and AM29 are closed head nozzles which are used on wet pipe systems. Both have successfully performed in full scale fire testing by Factory Mutual as described in the Class 5560 protocol. The open deluge AM4 nozzle is also both UL and FM approved.

        Ansul R-102 Kitchen Suppression Systems

        Aspect fire solutions are specialists in the supply, installation and maintenance of Ansul R-102 fire suppression systems.

        In a busy catering environment or large company providing catering for its staff, it is necessary to take adequate precautions against fire to ensure the ongoing, successful operation of your company.

        Imagine losing your business through fire damage

        In todays commercial kitchens, higher temperature cooking oils, high-efficiency, slow-cooling appliances such as deep fat fryers have combined to make fire suppression more challenging than ever. But the fact remains: the need to protect people and property from fire is crucial. And the system more and more food service operations are trusting to do this is Ansul R-102.

        Contact Us

        How Does Ansul R-102 Work?

        The R-102 system uses tried and tested fusible link technology to quickly detect a fire. It can also simultaneously interface with any gas valve/electrical supply to the equipment the fire is detected on.

        The R-102 Suppression agent is discharged onto the fire, forming a solid layer of foam, this instantly cuts off the oxygen supply to the fire, suppressing it within 30 seconds – and cooling it. People are protected and surrounding damage is minimised.

        The kitchen can be cleaned up immediately and the restaurant can resume normal operations in the shortest possible time.

        We offer installation and a 24/7 call out and maintenance facility for R-102 Systems to keep your system in optimum working order and to keep your business running.

          VESDA HSSD Systems

          As the name suggests Vesda HSSD Systems are highly sensitive smoke detection systems.

          They can detect a potential fire in its very early stages, long before a conventional smoke detector would activate.

          Vesda HSSD Systems are normally installed in the following types of areas:

          • Computer rooms
          • Communications centres
          • Clean rooms
          • Data centres
          • Switch rooms
          • Archive stores.

          Generally areas where high value, business critical systems are in use, often interfaced with Fire Suppression Systems.

          Vesda Systems

          VESDA very early warning aspirating smoke detection solutions with continuous air sampling provide the earliest possible warning of an impending fire hazard. VESDA HSSD systems also have the added benefit of potentially reduced maintenance costs compared to point type or beam detection.
