The UPS provides alarm functions, such as faults and input power interruption. When the UPS power supply is abnormal, the alarm sends a voice alarm message to inform users of the UPS operating status in time. What causes the UPS uninterruptible power alarm to go off? What to do when the alarm goes off?
● The UPS power system is short of power
Consider the UPS uninterruptible power supply system is not short of electricity, if there is a lack of electricity, the alarm will automatically ring, in fact, this phenomenon of lack of electricity can be known by a simple check, understand this situation after the timely charging, do not let the UPS in a long-term state of lack of electricity.
● Power failure of external power supply
In use process, if the power is external power supply, plus there is in a state of loss of electricity, alarm will be ringing off the hook, at this time due to the outside and there was no electricity, so there is no way to plug in the power supply, the best is to keep the shutdown of the state for a period of time, wait to call charging, is directly connected to UPS power after such alarm won't ring.
● The line is faulty
UPS uninterruptible power supply involves complicated lines, there are a lot of circuit board, if the trouble with the line inside, can through the way of alarm to remind, so this time is the need for professional maintenance, the inside of the fault lines to replace or reconnect the correct, so the sound of the alarm will automatically stop.
● Voltage fluctuation range is too large
UPS power supply voltage fluctuation range is too large, has exceeded the normal range of voltage fluctuation of the product, then out of self-protection at this time, there will be constant alarm.
Even if you want to turn off the alarm is impossible, unless the voltage is back to the normal range, then this time to suspend the use, and then check the cause of the voltage fluctuation range is too large, in time to avoid this situation again.
● UPS power supply runs over load
UPS power supply over load operation will also alarm (overload is not much, generally more than the overload UPS power supply in the specified time will shut down their own protection), at this time is not the UPS itself fault, as long as the overload of equipment to stop a number of UPS power alarm will disappear.
There are many reasons why the UPS power alarm always goes off, but there may be others. These reasons for the general user is not easy to think of, even so, can not rely on their own to solve the problem, it is best to let the manufacturer's after-sales staff to solve this problem, after-sales staff can take some instruments to check, in order to find out the specific problem.
