Operating Power
The 411UD may be powered from UL listed control panels that output nonresettable and power-limited 12 or 24
VDC power. The configuration of Jumper J4 determines whether 12 VDC power is to be supplied directly to the
411UD circuit board or 24 VDC power is to be supplied and then internally regulated down internally to 12 VDC.
DC Power - TB1 Terminals 4(+) and 5(-), Terminal 6 is Earth Ground
• J4 Jumper removed - Filtered, nonresettable and power-limited 24 VDC (nominal) power must be supplied at
TB1 Terminals 4(+) and 5(-). Operating voltage provided must be within 21.3 to 24.0 VDC (UL tested range:
-15%, +10%). Current requirements are 100 mA in standby and 170 mA

while communicating.
• J4 Jumper installed - Filtered, nonresettable and power-limited 12 VDC (nominal) power must be supplied at
TB1 Terminals 4(+) and 5(-). Operating voltage provided must be within 11.2 to 12.4 VDC (UL tested range:
-15%, +10%). Current requirements are 100 mA in standby and 170 mA
