Even the smallest of home UPS systems comes equipped with a host of features designed to update you on the operational status of your system. Depending on the exact make and model you own, these may include a variety of LED status lights and audible alarms. The problem is, many people are not sure what these lights and alarms mean, so they don’t know how to respond to them. If you invest in a commercial system from UPS Solutions, we’ll provide you with all the information you need on your UPS alarm and warning lights. If you buy a unit from a local retailer, the information below could help you to decode any alarms or warning lights.

UPS warning signs

Depending on the type of power supply alarm system that your UPS unit is fitted with, you may see any or all of the following indicators.

  • Green LED light — A steady green LED light typically means that everything is fine. Your UPS is online and is functioning normally.
  • Orange LED light — If you see an orange LED light on your system, this could mean a number of things, depending on the make and model in question. It may simply mean that the system has switched to battery power, owing to a failure in the mains electricity power supply. Alternatively, it may be a warning that your UPS battery is no longer in a healthy condition or that some other component has failed and needs attention.
  • Red LED light — Whatever type of UPS system you own, a red warning light is almost always a sign that a critical error has occurred. You should contact your supplier or the manufacturer without delay.
  • Audible alarms — Many UPS systems are equipped with audible alarms. To ascertain their meaning, refer to the manual provided with your system. The most common reason for a steady beeping alarm is to alert you that the power supply has been interrupted and your system is now running from the backup battery.
