  • AOV SMOKE SHAFT SYSTEMS

    Suitable for a wide range of buildings

    Pre-designed systems and products that ensure code-compliant solutions using CE certified equipment

    AOV smoke systems are generally located within a protected lobby, where they are attached to a rising smoke shaft with a termination vent at its head.

    A typical system consists of actuated fire doors or smoke damper and grille sets. A free area of 1m2 is provided (the smoke shaft itself having a footprint of 1.5m2). Zone control units are networked and include fire officer over-ride switches and smoke detectors (or an interface connection from the landlord’s fire door system).

    Ventguard AOV smoke shaft systems are designed/installed in accordance with the relevant sections of the SCA guide, Approved Document B, BS7346-8, BS9991, EN12101-2, EN12101-8, EN12101-10, ISO21927-9.

  • OV/AOV WINDOW SYSTEMS

    Suitable for a wide range of buildings

    Pre-designed systems and products that ensure code-compliant solutions using CE certified equipment

    A typical OV/AOV window system is located within a protected lobby and consists of an actuated window or glazed louvre unit that provides a free area of 1.5m2, a networked zone control unit with a fire officer over-ride switch and, in the case of AOV systems, a smoke detector.

    Multi-level buildings are networked to ensure that only the fire floor operates in the event of a fire.

    Vent-Guard OV/AOV window systems are designed/installed in accordance with the relevant sections of the SCA guide, Approved Document B, BS7346-8, BS9991, EN12101-2, EN12101-10, ISO21927-9.

  • OV STAIRCASE SYSTEMS

    Suitable for a wide range of buildings

    Pre-designed systems and products that provide code-compliant solutions using CE certified equipment

    A typical OV staircase system is located within a protected stairwell and consists of either an actuated window or a roof-mounted ventilator unit (providing a free area of 1.0m2) and a zone control unit (networked if it connects to other zone control units). Fire officer over-ride switches are provided at the fire service entrance level. Smoke detectors can be added if the stairwell and building layout require them.

    Vent-Guard OV staircase systems are designed/installed in accordance with the relevant sections of the SCA guide, Approved Document B, BS7346-8, BS9991, EN12101-2, EN12101-10, ISO21927-9.

  • MECHANICAL SMOKE VENTILATION SYSTEMS (MSVS)

    Suitable for a wide range of buildings

    Pre-designed and bespoke systems and products that provide fully-engineered solutions using CE certified equipment

    A typical MSVS system is located within a protected lobby and is attached to a rising smoke shaft or fire-rated ductwork system with a fan set at the shaft’s head.

    Systems often allow extended travel distances within the lobby and generally consist of a rooftop fan set and a series of smoke dampers and grille sets that provide a free area of 0.6m2 (the smoke shaft/ducting itself also having a footprint of 0.6m2). Zone control units are networked and include fire officer over-ride switches and smoke detectors (or an interface connection from the landlord’s fire alarm system).

    In some cases, pressure sensing is also utilised to reduce fans speed during means of escape mode and to allow occupants to escape without the exit doors being difficult to open.

    Vent-Guard mechanical smoke ventilation systems are designed/installed in accordance with the relevant sections of the SCA guide, Approved Document B, BS7346-8, BS9991, BS9999, EN12101-2, EN12101-3, EN12101-8, EN12101-10, ISO21927-9.

  • STAIRCASE PRESSURISATION SYSTEMS

    Suitable for a wide range of buildings

    Pre-designed and bespoke systems and products that provide code-compliant solutions using CE certified equipment

    A typical staircase pressurisation system is located within a protected stairwell to prevent smoke from contaminating the critical escape route. If the building is greater than 11m in height, the system should supply air into the stairwell at every third level and should ensure via a twin air inlet arrangement that nno smoke will be drawn back into the system. Each lobby has an air release facility.

    A staircase pressurisation system generally consists of a rooftop fan set and a twin air inlet duct arrangement together with a series of smoke damper and grille sets (the inlet duct size is calculated specifically to suit the building requirements). Zone control units are networked and include fire officer over-ride switches, pressure sensors and smoke detectors (or an interface connection from the landlord’s fire alarm system).

    Vent-Guard staircase pressurisation systems are designed/installed in accordance with the relevant sections of the SCA guide, Approved Document B, BS7346-8, BS9991, BS9999, EN12101-2, EN12101-3, EN12101-6, EN12101-8, EN12101-10, ISO21927-9.

  • CAR PARK VENTILATION SYSTEMS

    Suitable for a wide range of buildings

    Pre-designed and bespoke systems and products that provide fully-engineered solutions using CE certified equipment

    Car park ventilation systems are located within covered or enclosed car parks, loading docks and service roads to remove day to day pollution from vehicular traffic and smoke in the event of a fire. Systems generally consist of a main extract fan set, a series of impulse/induction fan units, a main system control unit with a fire officer over-ride switch, CO detectors and smoke detectors (or an interface connection from the landlord’s fire alarm system). For multi-level car parks damper and grille sets are installed between floor levels.

    Vent-Guard car park ventilation systems are designed/installed in accordance with the relevant sections of the SCA guide, Approved Document B, Approved Document F, BS7346-7, BS7346-8, BS9991, BS9999, EN12101-3, EN12101-8, EN12101-10, ISO21927-9.
