High decibel electronic alarm JDW-400/450: a key tool for air defense and flood drills
The JDW-400 and JDW-450 high decibel electric alarms are robust industrial grade alarm systems designed specifically for large-scale emergency drills, including air defense and flood control exercises. These alarms are powered by three-phase 380V electricity and have excellent performance, capable of immediately issuing alarms.
These alarms are made of heat-treated aluminum alloy, which can resist corrosion, aging, and environmental pressures such as wind, sand, and bird nests. The carefully selected materials ensure durability under harsh outdoor conditions, making it an ideal choice for installation in military bases, airports, prisons, hydropower stations, and disaster prone areas. The enhanced design of JDW-450 includes specialized heat dissipation slots, extending its service life and ensuring consistent performance within a coverage area of 5000 meters.
In addition to military applications, these alarms play a crucial role in civil defense and disaster management. Their multifunctionality supports scenarios such as mine safety alerts, prison emergencies, and flood warnings, and is compatible with industrial parks, schools, ports, and residential areas. The compact frame of JDW-400 and the structure of JDW-450 prioritize installation convenience without affecting power.
In summary, the JDW-400/450 alarm represents a fusion of reliability, adaptability, and technological resilience. Their ability to operate autonomously during communication interruptions, such as post attack scenarios or natural disasters, makes them an essential asset for ensuring public safety in modern emergency response frameworks.
