Sound and light voice alarm for coal mines factory direct sales
#Sound and light voice alarm for mine B explosion-proof language sound and light alarm B type intrinsically safe voice sound and light alarm Device B explosion-proof and intrinsically safe verbal sound and light alarm Dongda Group sales hotline: Manager Zhao.
#B explosion-proof and intrinsically safe verbal sound and light alarm is mainly used in places containing explosive gases underground in coal mines. It can also provide sound and light alarms at the entrance, exit or crossroads of transportation tunnels. Used as sound and light alarm for shaft hoisting. The B explosion-proof and intrinsically safe verbal sound and light alarm not only has the function of dotting and light indication during dotting, but also has voice prompts to make it comply with the latest "Coal Mine Safety Regulations" requirements. Dongda Group sales hotline: Manager Zhao.
#B Mine intrinsically safe sound and light alarm operating environmental conditions
#) Ambient temperature: ℃～+℃
#b) Average relative humidity: &;﹪(+℃)
#) Atmospheric pressure: ~
#) Place of use: with methane , coal dust explosive mixture but no corrosive gas that damages the insulation
#B Structural characteristics and working principle of intrinsically safe sound and light alarm for mines
#This alarm integrates two cavities to separate the explosion cavity and intrinsically safe cavity circuit. It adopts the modular design of electro-optical coupling device with integrated voltage comparator and high sensitivity. The overall layout is reasonable, small in size and light in weight. Dongda Group sales hotline: Manager Zhao.
#The alarm has two states: one is standby state; the other is alarm state. The green light is always on during standby and the red light flashes during alarm. The speaker issues a verbal warning of "driving and no pedestrians allowed". When the operator presses the button, the normally open contact closes and the internal conduction of the alarm is conducted. At this time, all the alarms on the road are driven to send out dot signals. The time interval between the operator's continuous operation of the button twice or more shall not exceed seconds (adjustable) and the alarm will change to the alarm state. The alarm state will remain in the alarm state for up to minutes (time is adjustable). During the alarm process, the operator presses the button once to stop the alarm and change the alarm to standby state. The device can also be used in series with an electric bell at the same time and the operation method is the same. B
