- 4 - AL300ULX series
Installation Instructions (cont’d):
2. Set the unit to the desired DC output voltage by setting SW1 (Fig. 1c, pg. 3) to the appropriate position
(Power Supply Output Specification Chart, pg. 2).
3. Securecabinettoearthgourd.ConnectACpower(115VAC/60Hztoterminalsmarked[L,G,N](Fig. 1, pg. 3).
Use14AWGorlargerforallpowerconnections(Battery,DCoutput,ACinput).
Use22AWGto18AWGforpowerlimitedcircuits(ACfail/LowBatteryreporting).
Keep power limited wiring separate from non-power limited wiring (115VAC / 60Hz Input, Battery Wires).
Minimum 0.25” spacing must be provided.
ForFireAlarmapplicationstheoutputsare“SpecialApplications”onlyseelist(refer to Appendix A, pg. 6).
For other devices contact Underwriters Laboratories to insure compatibility.
4. Measureoutputvoltagebeforeconnectingdevice.Thishelpsavoidpotentialdamage.
When servicing the unit, AC mains should be removed.
5. Connect devices to be powered:

b. ForotherPowerDistributionModelsconnectdevicestobepoweredtoterminalpairs1to4marked
[1P&1Nthru4P&4N](Fig. 2a & 2b, pg. 5)or1to8marked[1P&1Nthru8P&8N](Fig. 3a & 3b, pg. 5)
carefully observing correct polarity.
6. For Access Control applications, batteries are optional. When batteries are not used a loss of AC will result in the
loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.

+DC--- 12VDC or 24VDC @ 2.5 amp continuous power limited output.
AC Fail
NC, C, NO
IndicateslossofACpower,e.g.connecttoannunciator/alarmpanel.Relaynormallyenergized
when AC power is present. Contact rating 1 amp @ 28VDC. AC Fail condition will report
approximately within one (1) minute after loss of AC. To delay report for 6 hours cut jumper J1
onthePowerSupplyBoard(ACtroubleoutputdelayoption).Ifthismodeisselected
the Power Supply Board must be reset by removing all power to it for 30 seconds.
Bat Fail
NC, C, NO
Indicateslowbatterycondition,e.g.connecttoalarmpanel.RelaynormallyenergizedwhenDC
power is present. Contact rating 1 amp @ 28VDC. Low battery conditions will report
approximately 21VDC (24VDC output setting) or approximately 10.5VDC (12VDC output setting).
Battery presence detection will report approximately 1 minute after battery remains undetected
(missing or removed).
+BAT--- Stand-bybatteryconnections.Maximumchargecurrent0.7amp.
