ABC powder fire extinguisher mechanism of chemical inhibition, blocking the chain reaction of combustion, fire fighting high-level, full-featured, quickly extinguishing electrical insulation properties and good low temperature performance, especially suitable for use in factories and enterprises, warehousing and outdoor configuration . Inadequacies that: powder extinguishing agent is not anti resurgence, fire extinguishing an oil fire fighting level (B class fire), the user will be required to go through specialized technical training; powder fire extinguisher in use, especially in indoor use, stimulate the respiratory tract; fine dust filled the entire space, the use of dry powder fire extinguishers in the buildings, causing serious secondary pollution.

The fire alarm system is a life-saving system in the early days of the fire, smoke, heat and light radiation and other physical quantities can fire detectors combustion into electrical signals transmitted to the fire alarm control, and at the same time shows the site of the fire, record the time the fire broke out. So fire detectors is an important part of the fire alarm system, fire alarm system performance superiority is also reflected through the fire detectors. This requires the user to choose the relatively superior product, we should pay attention to the automatic fire alarm products, especially in the maintenance of fire detectors.
