The need for controlling high level ventilation in buildings is universally appreciated, and wherever out of reach ventilators are incorporated there is a requirement for simple, economic and unobtrusive type of gear. |

Fire & Smoke Control Systems |
||||
Based on our experience with specialist smoke and ventilation sub contractors, we have outlined below important points regarding fire and smoke controlled systems. 2. Ventilator controls that are to be used and operated under a fire and smoke situation (in addition to natural ventilation) will always require an emergency power supply (battery backup). 3. The Building Control officer and Fire officer must also be satisfied with the level of smoke ventilation in the building as a whole (the glazing must not be a standalone item), and many criteria can affect the level of ventilation required. 4. The Smoke ventilators to the patent glazing may form part of a Building Management System (B.M.S) and therefore may be required to be compatible for inclusion within the concept as a whole. Our general policy is for the Specialist responsible for the supply of all fire and smoke control systems to "free issue" The Standard Patent Glazing Company with the correct type and number of Smoke Vents, so that our installation team can incorporate them into the glazing system only - (totally exclusive of electrical work and wiring etc). The smoke vents are then ready to accept the electrical connections of the specialist. Then at a later, pre-arranged date, the system will be commissioned by the specialist, prior to handover. By the above means the guarantee for the system will rest with the supplier/installer and split responsibility will not inconvenience the final building user. If the Designers are satisfied that the number of ventilators and sizes of each unit are sufficient for the smoke ventilation requirements for the building, then we may be able to offer the supply of a smoke control system based on information in the Tender Drawings and any specifications in your possession. Due to the nature of this work, we would look to Sub-Let the works to a recognised Specialist Smoke and Ventilation Sub Contractor. |
