KXB18 mine intrinsically safe sound and light alarm Features: KXB18 mine intrinsically safe sound and light alarms by equipment control for the sound and light signals indicating underground methane, carbon monoxide and other parameters are overrun, and switch the alarm if abnormal mine of information security with a fixed instrument for coal mine use in each workplace. Alarm for the mining intrinsically safe, reliable, simple structure and easy to use. Use of environmental conditions - Ambient temperature: -5 ℃ ~ 40 ℃; - Relative humidity: ≤95% (+ 25 ℃); - Atmospheric pressure: (80 ~ 116) kPa; - no significant vibration, shock and watering place; - a mixture of methane gas and coal dust with a dangerous coal mine explosion. Storage temperature: -40 ℃ ~ 60 ℃. Explosion-proof type and explosion-proof mark type: Mine intrinsically safe; proof mark: ExibⅠMb. KXB18 mine intrinsically safe sound and light alarm main technical parameters 1. General performance: a) Operating voltage: 12 ~ 24V DC; b) Operating Current: ≤100mA; c) control signal: 0/5 ~ 24V DC voltage signal; d ) Transmission cable: four-core cable, the maximum transmission distance 2km 2. Alarm functions: a) sound level intensity: ≥85dB; b) alarm light signals:. 20m at clearly visible. c) When the alarm has 0/5 ~ 24V DC voltage mode control signal, the alarm audible alarm; to the contrary, when the control signal to stop the alarm sound and light alarm.
