November 18, 201510 yr My UPS alerts are a bit nervous lately. Often 1-3 per day in spite of there being no power issues. Yesterday I have alerts at 15:47 15:50 15:50 23:57 23:58 23:59 Here is the settings for my daemon on unRaid 6.1.3 UPS Settings UPS Details Key Value Key Value APC 001,037,0938 DATE 2015-11-18 08:21:53 -0600 HOSTNAME Kim VERSION 3.14.13 (02 February 2015) slackware UPSNAME Kim CABLE USB Cable DRIVER USB UPS Driver UPSMODE Stand Alone STARTTIME 2015-11-15 04:40:01 -0600 MODEL Back-UPS BR1000G STATUS Online LINEV 121.0 Volts LOADPCT 12.0 Percent BCHARGE 100.0 Percent TIMELEFT 62.7 Minutes MBATTCHG 10 Percent MINTIMEL 10 Minutes MAXTIME 0 Seconds SENSE Medium LOTRANS 88.0 Volts HITRANS 147.0 Volts ALARMDEL No alarm BATTV 27.3 Volts LASTXFER Unacceptable line voltage changes NUMXFERS 29 XONBATT 2015-11-18 00:00:02 -0600 TONBATT 0 Seconds CUMONBATT 95 Seconds XOFFBATT 2015-11-18 00:00:03 -0600 SELFTEST NO STATFLAG 0x05000008 SERIALNO 3B1104X46951 BATTDATE 2011-01-23 NOMINV 120 Volts NOMBATTV 24.0 Volts NOMPOWER 600 Watts FIRMWARE 868.L2 .D USB FW:L2 END APC 2015-11-18 08:22:05 -0600
November 18, 201510 yr Many UPS also kick-into backup mode when the line voltage goes either high or low. You probably would never notice the voltage transients but they can damage sensitive electronics. Your Back-UPS BR1000G provides protection against these events.

You probably would never notice the voltage transients but they can damage sensitive electronics. Your Back-UPS BR1000G provides protection against these events. So your suggestion is "don't worry about it"?? Can we adjust the alert sensitivity? I don't want to have my alerts become plugged with irrelevant stuff. Update: It was my laser printer that is plugged in for surge protection only, into the same ups. When it tries to print, it pulls a significant load and causes the ups to momentarily activate.
November 20, 201510 yr Why would you put your printer on your UPS in the first place? If it's a true laser printer, seems like the heater would drain your UPS in a second. Is it that important to print when the lights go out?

My Brother Laser printer has such a instantaneous draw that it would trip the AFCI breaker that (for some reason) is required for all bedrooms in our local building code. ( Don't ask why!!) (One bedroom in our home has been converted to a home office.) I ended up installing a separate 20 ampere run just for it. You can try plugging it straight into a outlet rather than the UPS's surge socket but you may still have the same issue. Even 12 and 14 gauge wire have IR (voltage) drops and the length of the run will determine what that drop is. Your choice then will be a separate circuit or living with the notices in the log.
November 21, 201510 yr Going to +1 moving the printer off the UPS... even better, off the circuit (so probably a different room in your home).
