ETA Systems ® - SECURITY ONE UNINTERRUPTIBLE POWER MANAGER
Status Monitor
The status monitor is a row of six individual LEDs that each indicate the status of a part of your UPM
system. The first three LED's work with Security One's Voltage Manager. All six LED's are explained in the
following table.
LED 1 Voltage Manager Boost Mode: When this LED is illuminated, Voltage Manager has detected that
a low voltage condition exists, and it is compensating by increasing voltage to the UPM input to
the correct level.
LED 2 Voltage Manager Normal Mode: Voltage Manager has determined that input line voltage is
normal and within parameters. No adjustment is necessary.
LED 3 Voltage Manager Buck Mode: When this LED is illuminated, Voltage Manager has detected that
an overvoltage condition exists, and it is compensating by reducing voltage to the UPM input to
the correct level.
LED 4 Battery Mode: When this LED is illuminated, either commercial AC power has been lost or the
UPM has been put into self-test using the Test/Silence button. In Battery Mode, the UPM is
operating on its internal batteries. This LED will remain illuminated until the self-test is completed
or until commercial AC power returns.
LED 5 Battery Weak: When this LED is illuminated, the battery requires either recharging or
replacement. If the LED remains illuminated after a 12-hour charge period, the internal battery
should be replaced.
LED 6 Overload: When this LED is illuminated, the UPM is overloaded. Remove load from the UPM by
determining, which of the connected pieces of equipment is the least critical, and disconnect it
from the UPM. Operating the UPM in an overloaded condition, may cause the UPM to protect
itself by shutting down and removing power unexpectedly to all connected components.
Configuration Manager Receptacle Indicators
The four clustered LEDs in the center of the front panel indicate the output receptacle status as controlled by
Configuration Manager. Configuration Manager addresses receptacle control differently for some of the
models (See following explanation).
420 VA models: Configuration Manager treats receptacles 1and 2 as a group (Bank 1) and receptacles
3 and 4 as a group (Bank 2). For these models, LED 1 and 2 (Bank 1) will either be on together or off
together. LEDs 3 and 4 (Bank 2) will also be on or off together. It is not possible to control receptacles
1 and 2 or receptacles 3 and 4 separately. It is only possible to separately control Bank 1 and Bank 2.
600 and 800 VA models: The top two receptacles are Bank 1 and the bottom four receptacles are Bank
2. On these models, LED 1 and 2 (Bank 1) will either be on together or off together. LEDs 3 and 4
(Bank 2) will also be on or off together. It is not possible to control receptacles 1 and 2 or receptacles 3,
4, 5 and 6 separately. It is only possible to separately control Bank 1 and Bank 2.
