5.2 Test switch (on units so equipped)
When the Test switch is pressed, the UPS simulates a power outage and transfers your load to the alternate power source. This feature
allows you to determine that computer equipment protected by the UPS operates normally during transfers. It also provides a convenient means of testing the UPS’s battery. If the Test control
is held depressed, the UPS will operate your equipment from power derived from the battery continuously. If during the test the low battery warning is sounded prematurely and the load is known to be normal, then the battery is weak and requires extended recharge or replacement (see section 7.0).
5.3 Audible alarm
During a utility failure, the UPS emits a series of four beeps once every 30 seconds to warn you that your equipment is operating from a source of power which is limited in duration. In the event of an extended utility failure, the UPS will sound continuous beeps 2 minutes in advance of shut down due to battery capacity exhaustion. Once shut down, the UPS will cease sounding the alarm. In the event the UPS encounters a severe overload, the UPS will shut down and emit a loud tone. The alarm is reset when the UPS is turned off. The UPS will shut down and sound the audible alarm when an internal fault is detected.
