Generally, the uninterruptible power supply itself has alarm functions, including failures, interruption of input power, etc. When an abnormal situation occurs in the UPS system, the alarm will send out a voice alarm message to promptly notify the user of the current working status of the UPS.

What caused the UPS uninterruptible power supply alarm to sound?

Why uninterruptible power supply beeping?

When using UPS uninterruptible power supply, different alarms will appear, and the meaning of each alarm will be different. When UPS occurs an alarm, it locates the detailed reason immediately and informs the user and records and saves it, so that the user can deal with it in time and avoid the occurrence of accidents.

Lithium ion UPS system

There are many reasons why the UPS power alarm keeps sounding, but it basically means that the UPS power supply is abnormal. The reasons are as follows:

01 The UPS power system lacks power

A continuous beep (once every two seconds and never stops) usually means that the battery of the UPS is very low and you should shut it down immediately. If there is no power failure and regular beeps are still emitted, your UPS will notify you that the self-check has failed. Charge it in time after learning about this situation, and don't leave the UPS in a long-term lack of power.

02 External power failure

Consider whether the UPS is short of power inside. If it is said that there is no power, the alarm will automatically sound. In fact, the phenomenon of power shortage can be known by a simple inspection. Once you understand this situation, you can promptly Do not let the UPS be in a state of lack of power for a long time.

03 The line is faulty

UPS involves more complicated lines, and there are a lot of circuit boards. If it is said that there is a fault in the line inside, it may be reminded by means of an alarm. At this time, professional maintenance is required to fix the fault inside. If the line is replaced or reconnected correctly, the alarm sound will stop by itself.

04 The voltage fluctuation range is too large

The UPS power supply voltage fluctuation range is too large, which has exceeded the normal voltage fluctuation range of the product, so at this time, due to the effect of self-protection, there will be constant alarms.

05 Overload operation of UPS power supply

UPS power supply overload operation will also alarm (the overload is not too much, generally the UPS power supply will shut down within the specified time for protection), at this time it is not the UPS itself failure, as long as the overloaded equipment is stopped for a few times, the UPS power supply alarm will disappear.

06 Internal circuit error of UPS system

An internal circuit error has been detected (the mode will vary depending on the error). If the UPS model has LCD/LED display, please check if any error code is flashing, you can verify the details from the user manual.

There are many reasons why UPS power alarms always sound, but there may be other reasons. These reasons are not easy for the average user to think of.

Even if this is the case, you can't solve it by yourself. It is better to let the official after-sales personnel solve the problem. After-sales personnel can bring some tools to check in order to find out the specific problem.

How to easily send out an alarm when the UPS power supply is abnormal?

Regardless of whether it is a bank, a hospital, a government agency or a school, there is a computer room, and there will be UPS power in the computer room. However, many users do not implement any monitoring measures on the UPS when using the UPS power supply, which is the "streaking" state.

Therefore, in order to avoid the UPS "streaking" state, the UPS is monitored to ensure the normal operation of the UPS, while also ensuring the safe operation of the computer room.

UPS smart SMS alarm is a device SMS alarm device that fully embodies the characteristics of wireless, stability, simplicity, and high mobility.

It can provide users with accurate, even, and reliable alarm and warning information, mainly for a large number of application equipment and systems that exist in the computer room application environment, IT application environment, and industrial application environment.

For example, various network equipment and systems such as servers, routers, UPS power supplies, firewalls, application software, etc., use wireless networks to realize the rapid dissemination of alarm information, reaching the hands of equipment managers, IT network maintenance personnel, and applying them to data centers, power system automation, Departments of industrial monitoring, traffic management, meteorology, finance, securities, etc.

24-hour real-time monitoring of the real-time status of the UPS power supply. When abnormal conditions such as mains power failure, temperature and humidity exceeding upper/lower limits are monitored, the detailed fault notice can be bound to the mobile phone number through SMS and phone calls (voice). User.

In the case that the user's UPS power supply itself supports remote control switch, self-test and other functions, the user can send SMS commands through the mobile phone to realize remote control of UPS shutdown, power-on, battery self-test and other functions, and receive UPS faults at the same time Call the police.


The above is the reason why the alarm of the UPS uninterruptible power supply system keeps ringing. The alarm of the UPS uninterruptible power supply system can remind operation and maintenance personnel to deal with problems in time, prevent accidents, and provide a cleaner and high-quality power supply function and a high-quality service power supply system.
