Liquid ammonia alarm
1. Overview of liquid ammonia alarm
The liquid ammonia alarm is a flammable and toxic gas alarm developed by our company with practical functions and easy operation. It can be combined with our company's flammable and toxic gas alarm controller to form an industrial gas alarm system. The controller can also be connected to the monitoring center computer through signals, and can query the on-site concentration remotely through the company's dedicated monitoring software, thus forming a multi-level monitoring network of remote monitoring, local monitoring, and on-site monitoring, which greatly improves This ensures the real-time and accuracy of monitoring.
The product adopts wall-mounted installation. It is used in conjunction with the controller and processes various data uploaded by the detector through the controller microcontroller, and finally completes functions such as data display and output control. .
The design, manufacturing and inspection of this product comply with the following national standards:
B "Combustible Gas Alarm Controller" National Standard One per square meter

3. Detector installation instructions
Installation location:
The detector is installed in a place where the detected gas is prone to leakage. The installation location is determined based on the specific gravity of the detected gas relative to air.
When the specific gravity of the gas to be detected is greater than the specific gravity of air, the detector should be installed at a distance (~) from the ground, with the sensor part facing downwards.
When the specific gravity of the gas to be detected is less than the specific gravity of air, the detector should be installed at a distance (~) from the ceiling, with the sensor part facing downwards.
Installation precautions:
In order to use the detector correctly and prevent detector failure, please do not install it in the following locations:
◆Places directly affected by steam and oil fume
◆ Places with large air flow such as air supply vents, ventilation fans, and doors
◆Places with a lot of moisture and water droplets (relative humidity: %
◆Places with temperatures below ℃ or above ℃
◆Yes Places with strong electromagnetic fields.
4. Maintenance of detector products
Precautions
◆. The detector has been strictly calibrated before leaving the factory. Please do not replace components at will after installation. If If it needs to be replaced, it must be recalibrated
◆. The normal service life of the detector's sensor is two years. Due to different use environments, its service life may decrease. It should be inspected and maintained regularly every year
◆. Detector The sensor is prohibited from being impacted by high-concentration gas, otherwise the sensor may be damaged
◆. Avoid frequent power outages of the detector. Frequent power outages will lead to unstable operation of the detection element
◆. During use, It is necessary to regularly check whether the instrument is working normally, and the inspection cycle is at least once every three months.
Analysis and troubleshooting of common faults
◆After the alarm system is installed, after the first power-on and preheating, an alarm or fault may occur. phenomenon, just reset the system and observe it for a period of time.
◆Power failure display
The standard configuration of the product does not include backup power. If the customer does not choose backup power, it will only be powered by the main power
When the power-on delay is completed, a fault alarm will be issued and the charging fault and fault indicator lights will be on. At this time, just press the silence button.
◆No display after turning on the power
Mainly due to wiring problems, first Check whether the power supply is connected properly and whether the socket is secure. After the power supply is correct, check whether the cables, pins and other connectors inside the controller are secure and whether they are loose.
◆Fault or concentration alarm when entering the monitoring state after preheating , the controller will display
The fault type:
It is a communication fault:
▲. Check whether the wiring is correct and whether the controller and the detector correspond
▲. The actual detector Is the number of connected channels consistent with the set number?
▲. The voltage of the detector is normal (the controller is the output, and the normal operating voltage of the detector is also, the minimum is not less than)
▲. The power supply is connected correctly In the case of .

On this day in history: < >Hong Kong Occupy Central organizer Joshua Wong , Luo Guancong was tried today
< >On the afternoon of October 2, Joshua Wong, the convener of the Hong Kong scholar-democratic movement, and Luo Guancong, secretary-general of the Federation of Students, discussed the burning of the white paper "The Practice of One Country, Two Systems in the Hong Kong Special Administrative Region" outside the Liaison Office of the Central People's Government last month. Accompanied by a lawyer, he went to the Western District Police Station to make an appointment for arrest. The two were charged with obstructing a police officer in the proper performance of their duties and were released on bail pending a public trial this Friday. This is the first time that Hong Kong police have formally charged a student leader.
