Installation Instructions:
The AL600ULB should be installed in accordance with article 760 of The National Electrical Code as well as NFPA 72
and all applicable Local Codes.
1. Mount the AL600ULB in location/enclosure.
2. Set the AL600ULB to the desired DC output voltage by setting SW1 to the appropriate position
(refer to Power Supply Output Selection chart).
3. Connect two(2) 28V
AC / 200VA transformers (connected in parallel) to terminals marked [AC]. 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 .25” spacing must be provided.
4. Measure output voltage before connecting device. This helps avoid potential damage.
5. Connect devices to be powered to terminals marked [+ DC –] (Fig. 1).
When servicing the unit, AC mains should be removed.
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 battery to terminals marked [+ BAT –] (Fig. 1).
AL600ULB - UL Recognized
Power Supply/Charger Rev. 100302
Overview:
The AL600ULB is a power supply that converts a 28VAC / 200VA input, to a 12VDC or a 24VDC output,
(see specifications).
Specifications:
Agency Listings:
• UL Recognized component for Access Control
System Units (UL 294), Standard for Safety
for Fire Protective Signaling Systems (UL 1481).
Input:
• Input 28VAC / 200VA.
Output:
• 12VDC or 24VDC selectable output.
• 6 amp continuous supply current
@12VDC or 24VDC.
• Filtered and electronically regulated output.
Battery Backup:
• Built-in charger for sealed lead acid or gel type batteries.
• Maximum charge current 0.7 amp.
Battery Backup (continued):
• Automatic switch over to stand-by battery
when AC fails.
• Zero voltage drop when switched over to battery backup.
Visual Indicators:
• AC input and DC output LED indicators.
Supervision:
• AC fail supervision (form "C" contacts).
• Low battery and battery presence supervision
(form "C" contacts).
Additional Features:
• Short circuit and thermal overload protection.
Board Dimensions (approximate):
4.3”W x 7.1”L x 2.3”H

7. Connect appropriate signaling notification devices
to [AC FAIL & BAT FAIL] (Fig. 1)
supervisory relay outputs. Note: When used in fire alarm,
burglar alarm or access control applications,
“AC Fail” relay must be used to provide a visual
indication of AC power on.
Maintenance:
Unit should be tested at least once a year for the proper
operation as follows:
Output Voltage Test: Under normal load conditions, the DC
output voltage should be checked for proper voltage level
(refer to Power Supply Voltage Output Specification chart).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage
both at battery terminal and at the board terminals marked [+ BAT –] to insure there is no break in the
battery connection wires.
Note: Maximum charging current under discharge is 0.7 amp.
Note: Expected battery life is 5 years, however it is recommended changing batteries in 4 years or less if needed.
LED Diagnostics:
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.
Terminal Identification:
Terminal Function/Description
Legend
AC/AC Connect 28VAC to these terminals from 2 connected in parallel transformers.
+DC –12VDC or 24VDC @ 6 amp continuous non-power limited output.
AC FAIL Used to notify loss of AC power, e.g. connect to annunciator/alarm
NC, C, NO panel. Relay normally energized when AC power is present.
Contact rating 1 amp @ 30VDC. AC Fail condition will report approximately
one (1) to one 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 Used to indicate low battery condition, e.g. connect to alarm panel.
NC, C, NO Relay normally energized when DC power is present.
Contact rating 1 amp @ 30VDC. Low battery conditions will report approximately 21VDC
(24VDC output setting) or approximately10.5VDC (12VDC output setting). Batterypresence
detection will report approximately 1 minute after battery remains undetected
(missing or removed).
+ BAT–Stand-bybattery connections. Maximum charge current 1.2 amp.
