An explosion-proof audible and visual alarm is a warning signal device that alerts people through sound and various types of light. When an accident, fire, or other emergency occurs at a production site, the control signal from the fire alarm controller activates the audible and visual alarm circuit, emitting sound and light signals to achieve the purpose of alerting.
How would you like to dramatically minimize your risk for costly workplace accidents? About $62 billion-that's how much workplace accidents and injuries cost US companies each year based on the 2016 Liberty Mutual Workplace Safety Index. That's more than a billion dollars per week. The thing is, you can avoid all this with the proper safety equipment.
Working Principle：
Usually consists of a detector and an alarm device. The detector is responsible for detecting dangerous factors in the environment, such as combustible gas concentration, temperature, pressure, etc. When the detected parameters exceed the set safety threshold, the detector will transmit a signal to the alarm device. After receiving the signal, the alarm device will sound an alarm through a high-decibel sound and bright flashing lights to attract people's attention.
 Sound and light components: equipped with high-brightness LED lights and high-power buzzers or speakers. The lights usually have a variety of flashing modes, such as strobe, flash, etc., and the colors are mostly eye-catching colors such as red and yellow; the sounds can be designed as fire sounds, sirens, ambulance sounds, etc. according to needs, and the volume is generally above 100 decibels. |
 High protection level: It has a protection level of IP65 or higher, has good dustproof and waterproof performance, and can work stably in harsh outdoor environments or places with a lot of dust. |
 Explosion-proof housing: Made of special explosion-proof cast aluminum material and design, it can effectively resist explosion shock and high temperature, ensuring safe use in flammable and explosive environments. |
•Petrochemical industry: In places such as oil refining and chemical production, there are a large number of flammable and explosive gases and liquids. Explosion-proof sound and light alarms can promptly sound alarms when dangerous situations such as gas leaks occur.
• Mining industry: In coal mines, metal mines and other mines, there may be the risk of explosion of flammable gases such as gas. Explosion-proof sound and light alarms can be used to monitor gas concentrations and sound alarms when they exceed the standard.
• Gas industry: Gas storage, transportation and use places, such as gas stations and gas filling stations, require explosion-proof sound and light alarms to ensure safety.
