    Attention for installation:

    • Because this wall-mounted fixed aerosol fire protection system device is needed to install on the wall or the top of the ceiling, and each device will be several tens of kilograms in gross weight, so when installing it take care and make sure to firmly fix the bracket and screws.
    • Better to Install it at least 1/2 high of the room height.
    • Make sure the left side discharging outlet and right side discharging outlet are without any obstacles.

    Why we recommend of wall mounted aerosol for the market:
    Wall-mounted aerosol is mostly installed in computer rooms, data processing rooms, telecommunication rooms, and other buildings, and in China, we have many cases of installing it in the underground Integrated Pipe Gallery, which is a national project in China.
    Also, it covers more space and space-saving to install, some protection zones will need to require a device which is a space-saving device.
    An aerosol extinguishing device has with very high extinguishing ability.

    Safety Warning!
    Users should set warning signs in the following obvious locations, the words on the warning sign suggest like following:

    • inside the protection zone: “WARNINGS! This is S type aerosol fire extinguishing device protection zone, if you hear there is a fire alarm at the site, please escape immediately”.
    • At the location of the manual call point: “WARNING, When pressing down the manual call point button, please make sure there are no people at the site”.
    • Outside the protection zone: ” This protection zone is protected by aerosol fire extinguishing systems”.

    Device Maintenance
    to ensure the reliability of the hot aerosol fire extinguishing device, we should establish complete regulations for equipment inspection and maintenance, and make operation norms; the qualified inspector should inspect it and make a record regularly.
    During the maintenance period, the inspector must do an inspection job following relevant standards and specifications.
    1. Daily Maintenance (When the device is being in use)
    a. make sure the protection zone and fire alarm system control rooms are clean, dry, and well-ventilated.
    b. make sure the surface of the aerosol device and fire alarm control panel is without dust.
    c. check the nameplate of the aerosol device, that warning signs are intact, and that the check outlet of the aerosol device is not blocked.
    d. check whether the fire alarm system is at fault or not, or check whether it has an activation problem or not; if find any of the above problems, then please check and resolve it in time.
    2. Yearly Maintenance

    • Protection area opening situations, the aim of the protection area, protection types, quantities, and distribution of combustibles, factors should comply with fire protection standards and specifications.
    • Examine all aspects of the aerosol extinguishing devices, for example, to inspect whether all the components and parts are firmly fixed or not, and please clean up the device to make sure it will not have much dust.
    • After the aerosol units are put in use, their expiration date is about 7 to 10 years, after the expiration date, please try to contact the supplier for replacement.

    Aerosol fire protection systems have common features, normally described as follows:

    • The third aerosol technology, and refill with strontium nitrate and potassium nitrate of aerosol chemical powder, strontium nitrate takes a proportion of about 50%, and potassium nitrate takes about 10% to 20% proportion, china aerosol based compound is with advance technology and innovative.
    • it is non-toxic, non-corrosive, non-conductive, not have any residue after suppression.
    • It is Eco-friendly with zero value in Ozone-layer Depletion, Zero value in Global Warming Potential, and Low value in Atmospheric Life Time.
    • Space-saving and compact, simple construction, easy to install, easy to do system design, debugging, and installation.
    • Low in system maintenance after sale, not require years of inspection.

    Also, wall mounted type of aerosol devices have special characteristics, which are listed as follows:

    • Round cylinder shape like an indoor air conditioner.
    • Could be installed on the top ceiling of the room or the wall above the protection objective, it is space-saving for the project.
    • IP 67 in waterproof and dustproof performance.

    Remark: hereby IP is IP code, which means what is the grade of dust protection and water protection?
