How to share the correct debugging of electrical fire monitoring detectors?

After the installation of the electrical fire monitoring detector, it must be debugged before it can be used normally. Now the LN6M electrical fire monitoring detector developed and produced by Beijing Lebird Technology Co., Ltd. (Dongguan LeBird Electrical Technology Co., Ltd.) is used as an example. You describe how to commission the site when it is opened.
1, power check
After the installation of the electrical fire monitoring detector , it is necessary to power on first, and then when the power is on, observe whether the indicator on the detector display panel is normal, let them do a self-test once, then enter the normal operation state, and then run the silence indicator. The lights must be lit. The light alarms for fire alarms and fault alarms need to check whether they can operate normally. It is better that the lights of each joint point let him light up once to see if there is any indicator light. If there is a fault, it must be resolved in a timely manner.
2, set the loop
You can set the number of loops to 3 at the beginning. That is, the DIP switch is set to 0011. This actually represents the four working states of the DIP switch being ON, ON, OFF and OFF.
3, test current value
First of all, you should test the current value of the three circuit circuits under normal operating conditions, and then set the threshold of the three circuit fire alarms to a value slightly greater than this current value. After the setting is completed, it does not mean that the work has been completed. It is also necessary to connect the three current probes to the detector and wait until the probe is stable before collecting the signal. In 50 seconds, the circuit is not faulty. Occur, if any, it is necessary to carefully check the wiring is not good. After discovering the problem, first use a multimeter to measure the resistance value of the current probe. If it is infinity, it means that the current probe has been damaged and needs to be replaced. If there is no problem, it means that the cause of the failure is to take care of other needs. Check.
4, fault demonstration
After installing and debugging the electrical fire monitoring probe , it is also necessary to remove the current probe of any one of the three loops to see whether the loop will send a fault signal within 50 seconds. If so, it means the detector. Already working properly. This is the most basic current probe. This is just a test of the installation. It is also necessary to perform a demonstration of the failure of the fire so that any circuit is in a fire alarm state. If the circuit can also send a signal within 50 seconds, the other two circuits will not send a signal, it means that the detector's work is normal.
About chocolate molds: In our daily life,we usually like bake some dessert for friends as presents.And most of chocolate molds are made of silicone.And why people choose silicone chocolate molds? 1.Silicone material is Food Grade.2.Compare with common molds,Silicone Mold is cheaper than metal molds.3.Can do the own design more flexible.4.High temperature and low temperature resistance.5.Do not harmful people's health.6.Durable in use and easy to carry.7.Suitable for all people,Especially for dessert lovers and housewives.
