KXB127 flameproof and intrinsically safe language sound and light alarm
KXB127 flameproof and intrinsically safe sound and light alarm (Coal Safety No.: MHE120004) is mainly used for explosive gas-containing places in coal mines. It is used for spotting or sound and light alarms at entrances, exits, or at forks, and bends of transport lanes. It can also be used for shaft sound and light alarms, fork rail indications, and bend warnings to ensure work safety.
Second, the technical characteristics of the alarm device in one of two chambers, separate explosive cavity and intrinsically safe cavity, the circuit uses an integrated voltage comparator, high-intensity electro-optical coupling devices, modular design. The overall layout is reasonable, small size, light weight.
The alarm has two states, one is the standby state; the other is the alarm state. The operator operates two or more consecutive buttons, and the alarm device changes to the alarm state. During the alarm process, the operator presses a button, the alarm stops, and the alarm device changes to the standby state. The device can also be used together with the bell string at the same time.
Third, the main technical parameters Operating voltage: AC127V Operating current: ≤ 300mA
Intrinsically safe parameters: DC12.5V, 1A
Loudness: Not less than 85dB
The visible distance of the light signal The light signal is visible at 40m in the dark.
