    Why we recommend of wall mounted aerosol for market:
    Wall mounted aerosol is mostly install in computer rooms, data processing rooms, telecommunication rooms and other buildings, and in china we have many cases to install it in underground Integrated Pipe Gallery, which is a national projects in china.
    Also it is cover more spaces and space saving to install, some protection zone will need to require a device which is a space saving device.
    And aerosol extinguishing device is with very high extinguishing ability.

    Safety Warning!
    User should set warning sigh in the following obvious locations, the words on the warning sign suggest like follow:

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