Altronix AL300ULXR Installation Instructions - Manual (Page 4)

- 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. Secure cabinet to earth gourd. Connect AC power (115VAC / 60 Hz to terminals marked [L, G, N] (Fig. 1, pg. 3).
Use 14 AWG or larger for all power connections (Battery, DC output, AC input).
Use 22 AWG to 18 AWG for power limited circuits (AC fail/Low Battery reporting).
Keep power limited wiring separate from non-power limited wiring (115VAC / 60Hz Input, Battery Wires).
Minimum 0.25” spacing must be provided.
For Fire Alarm applications the outputs are “Special Applications” only see list (refer to Appendix A, pg. 6).
For other devices contact Underwriters Laboratories to insure compatibility.
4. Measure output voltage before connecting device. This helps avoid potential damage.
When servicing the unit, AC mains should be removed.
5. Connect devices to be powered:
a. For AL300ULX Power Supply connect devices to terminals marked [+ DC -- ] (Fig. 1, pg. 3).
b. For other Power Distribution Models connect devices to be powered to terminal pairs 1 to 4 marked
[1P & 1N thru 4P & 4N] (Fig. 2a & 2b, pg. 5) or 1 to 8 marked [1P & 1N thru 8P & 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.
Connect one (1) 12VDC battery to the terminals marked [+ BAT -- ] for 12VDC operation. Use two (2) 12VDC
batteries wired in series for 24VDC operation.
7. Connect appropriate signaling notification devices to AC FAIL & BAT FAIL (Fig. 1a, pg. 3) supervisory relay
outputs.
Note: When used in fire alarm, burglar alarm or access control applications, “AC Fail” relay should be
utilized to visually indicate that AC power is on. To delay report 6 hours cut “AC Delay” jumper (Fig. 1b, pg. 3).
8. Please insure that the cover is secured with the provided key lock.
LED Diagnostics:
Power Supply Board
Red (DC) Green (AC) Power Supply Status
ON ON Normal operating condition.
ON OFF Loss of AC, Stand-by battery supplying power.
OFF ON No DC output.
OFF OFF Loss of AC. Discharged or no stand-by battery. No DC output.
Red (Bat) Battery Status
ON Normal operating condition.
OFF Battery fail/low battery.
Terminal Identification:
Power Supply Board
Terminal Legend Function/Description
L, G, N
Connect 115VAC 60Hz. to these terminals: L to hot, N to Neutral, G to ground.
+ DC --- 12VDC or 24VDC @ 2.5 amp continuous power limited output.
AC Fail
NC, C, NO
Indicates loss of AC power, e.g. connect to annunciator/alarm panel. Relay normally energized
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
on the Power Supply Board (AC trouble output delay option). If this mode is selected
the Power Supply Board must be reset by removing all power to it for 30 seconds.
Bat Fail
NC, C, NO
Indicates low battery condition, e.g. connect to alarm panel. Relay normally energized when DC
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-by battery connections. Maximum charge current 0.7 amp.
