Product introduction:The ZHD-X12 dual-mode respirator HUD launch pressure gauge can display the pressure of the empty exhalation bottle, the remaining gas usage time, and the on-site ambient temperature; it has a fall alarm and LED lighting function, abandoning the traditional mechanical pressure gauge, and adopting dual-sensing acquisition technology , Double guarantee, double reliability.2. Features:Easy installation, small size, simple and stylish appearance.Simple operation, open the cylinder valve to start automatically.Using large capacity explosion-proof rechargeable lithium battery.Two sets of independent circuits and two air pressure sensors work independently on digital display and HUD transmission.Powerful function: mechanical pointer display, digital display, HUD launch, remaining time display, fall helper, temperature display and alarm.Humanized design, fall alarm and optional on or off, and have factory mode to set parameters such as alarm temperature and gas cylinder capacity according to demand.Low power consumption technology makes the standby time super long.Reservation upgrade function: It can be upgraded to an integrated monitoring and command system in the backyard of the air call.Waterproof: one meter water depth 24 hours.Explosion-proof: ExiaIICT4.Comply with 3C standard.3 Specifications:3.1 Respirator dual-mode HUD launch pressure gauge (ZHD-X12)3.1.1 Battery working time requirements3.1.1.1 Theoretical standby time (sleep): 1 year3.1.1.2 Continuous working time HUD without alarm connection:> 80 hours at normal temperature (> 30 hours at -30 ° C)3.1.1.3 Continuous alarm time:> 3 hours3.1.1.4 Continuous working time with low battery:> 2 hours3.1.2 Working temperature: -30 ºC ~ 70 ºC3.1.3 Digital pressure display accuracy: 1.63.1.4 Dustproof, waterproof, anti-drop, explosion-proof3.1.5 Explosion-proof grade: Exia IIC T4 Ga3.1.6 Dimensions:3.1.7 Weight: 350g3.2 HUD receiver (ZHUD-12)3.2.1 Power supply battery: 4.2V rechargeable lithium battery (300mAh)3.2.2 Theoretical standby time: more than 2 years (the characteristics of the lithium battery itself determine that it needs to be charged once in 1-2 years to prevent the battery from aging due to self-discharge and capacity reduction)3.2.3 Continuous working time: more than 100 hours under normal working conditions3.2.4 Sustainable working time when the battery is under voltage: more than 2 hours3.2.5 Working temperature: -30 ºC ~ 70 ºC3.2.6 Explosion-proof grade: Exia IIC T4 Ga3.2.7 Weight:4 Introduction and operation method of each part:4.1 Function introduction and use method of dual mode HUD launch pressure gauge (ZHD-X12)4.1.1 Switch on and offTurn on: Method 1-long press the power button for 4 to 6 seconds. Method 2-Open the high pressure valve of the gas cylinder, the output pressure of the gas cylinder is greater than 4MPa, Automatically turn on in 8-10 seconds.Shutdown: Method 1 --- When the pressure display value of ZHD-X12 is lower than 2MPa in the boot state, press and hold the power / function button for 3 seconds to shut down the system. When the pressure display value of ZHD-X12 is greater than 2MPa, the air pressure in the high-pressure pipe needs to be relieved of pressure until the display value is less than 2MPa before shutting down.4.1.2 Connection between ZHD-X12 and ZHUD-12 ZHD-X12 sends data such as gas cylinder pressure to the HUD receiver (ZHUD-12) to show that the two devices need to be connected to each other. The specific operations are as follows: In the case of power on, quickly press the power button twice to turn on the HUD pairing function. After turning on, the ZHD-X12 green pairing indicator flashes (for 60S). During this period, long press the ZHUD-12 pairing key to start pairing. Normal connection: If normally connected to ZHUD-12, the pairing indicator (H / blue light) of ZHD-X12 flashes once every 3 seconds. Disconnect: If disconnected, the pairing indicator will be off. Note: There are two cases of disconnection: ZHD-X12 shut down: After the ZHD-X12 shuts down, the two parties disconnected, and the ZHUD-12 is in standby. Turn on the ZHD-X12 main unit again, the two sides will automatically connect. Disconnect in other ways: For example, beyond the connection distance, the two enter the connectable range again, as long as the ZHD-X12 is turned on, both parties will automatically connect.4.1.3 Gas cylinder pressure display alarm function ZHD-X12 displays the pressure value in the gas cylinder in real time. For air calling, take the 6.8L gas cylinder as an example. When 1MPa≤gas cylinder pressure≤6MPa, the ZHD-X12 horn will beep rapidly, the volume will be greater than 90dB, and the flashing light will flash.4.1.4 Time display of remaining gas volume of gas cylinder The display screen shows the available time of the remaining gas volume in the cylinder in real time.4.1.5 Low battery alarm When the battery power is used to 20% of the total power, the battery icon starts to flash and it can work continuously for more than 2 hours.4.1.6 Helper function and fall alarm function After the user falls in distress, the static time is allowed to be 30 ± 2S. If the static time is exceeded, ZHD-X12 will start to sound the pre-alarm sounds of "Beep --- Beep", "Beep --- Beep", "Beep --- Beep" Pre-alarm time, pre-alarm time is 15 ± 2S, within the pre-alarm time, move ZHD-X12 again, the alarm will be automatically cancelled. After the fall alarm time exceeds 15S, that is, after the pre-alarm time, the pre-alarm sound becomes a more rapid and higher decibel "Di-du-" "Di-du-" beep sound, at this time by moving ZHD-X12 will The alarm cannot be cancelled, and the alarm can be cancelled only by short pressing the switch button. Active call for help function: When the user thinks that the situation is more dangerous, you can press the SOS button for 2-3 seconds to activate the call for help function. In the state of calling for help, short press the SOS button to cancel. Note: The fall alarm function is only valid when it is turned on. The villain icon directly below the display is an on and off sign. Fall alarm switch mode: Quickly press the LED lighting button 4 times.4.1.7 Real-time display of operating temperature ZHD-X12 displays the ambient temperature in real time.4.1.8 Zero When the ZHD-X12 is not connected to high voltage, the digital display is not zero after powering on. You can press the "screen change button / call for help" button 10 times within 5s, the display value starts to flash, and then press the power within 3s in this state / Function key to /confirm/i, the zero setting operation is completed.4.1.9 Voice broadcast Short press the power button to broadcast the current air pressure.4.1.10 Auto screen off / bright screen function Assuming that the ZHD-X12 display is placed horizontally on the desktop at 90 °, and the torch light is vertically down to 0 °, when the ZHD-X12 is in the 0-45 ° interval, the screen will automatically turn off after standing for 30S. After turning off the screen and lifting> 45 °, the display will automatically light up.4.1.11 Charging indication function When the battery icon shows that the charge level is less than 1 cell, please charge it in time. When charging, use the MIC USB interface to charge (currently most Android mobile phone chargers can be charged). When charging, the battery icon on the ZHD-X12 display will scroll. Do not use this product while charging.
