K8 ore pool setting
The alarm temperature of temperature sensor is generally set at about 57 ℃
there are more than 20 kinds of temperature detectors, including A1, A1R, A2 and a2r. The lower limit of action temperature of A1 is 54 ℃, and the upper limit of action temperature is 65 ℃; The lower limit of A2 action temperature is 54 ℃, and the upper limit of alarm temperature is 70 ℃
A1R and a2r with "R" mark have a differential temperature alarm, that is, within a certain period of time, if the temperature suddenly rises to a certain degree (such as 8.3 ℃ / M), it will alarm. The detection temperature is generally 54 ℃ - 70 ℃. According to the national standard, the highest detection temperature can reach 160 ℃

temperature alarm is also called temperature detector. In case of fire, the combustion of materials proces a lot of heat, which changes the surrounding temperature. The temperature detector is a fire detector that responds to the temperature change around a certain point or a certain line in the warning range. It is the change of temperature into electrical signal to achieve the purpose of alarm
according to the different monitoring temperature parameters, there are several types of temperature sensing fire detectors commonly used in instrial and civil buildings, such as constant temperature type, differential temperature type, differential constant temperature type and so on
Jtw-zcd-g3n features jtw-zcd-g3n point type temperature fire detector adopts two bus technology of non-polar signal, which can be connected in any way with the alarm bus of all kinds of fire alarm controllers proced by our company. It is especially suitable for places with severe temperature rise in case of fire, Combined with smoke detector, it can detect fire more reliably and rece loss. The detector has the following characteristics:(1) novel structure, beautiful appearance, stable and reliable performance
(2) MCU with a / D conversion is used to sample and process data in real time, and 14 historical data can be saved. The curve shows and tracks the situation of the scene
(3) the address code is written directly by the electronic encoder, so the engineering debugging is simple and reliable (4) the patent number is zl99311722.8 Main technical specifications of jtw-zcd-g3n (1) detector type: A1R(2) working voltage: bus 24 V

in March this year, the Ministry of instry and information technology of Inner Mongolia Autonomous Region and the Energy Bureau jointly issued the document "on ensuring the completion of & lt; The fourteenth five year plan; Several safeguard measures for the goal of double control of energy consumption. It is mentioned that in 2021, the al control target of energy consumption in the whole region is determined as: 3% rection of energy consumption per unit GDP, about 5 million tons of standard coal for energy consumption increment, about 1.9% growth of total energy consumption, and more than 4% rection of energy consumption per unit instrial added value (equivalent). In addition, the measures clearly point out that it is strictly forbidden to create new virtual currencies; Mining & quot; Project, thoroughly clean up and close the virtual currency & lt; Mining & quot; All the projects will be withdrawn before the end of April 2021
