AL1024ULXB2:
•  115VAC, 60Hz, 4.2A. 
ACMS8/ACMS8CB:
•  Eight (8) trigger inputs: 
    a) Normally open (NO) inputs (dry contacts). 
    b) Normally closed (NC) inputs (dry contacts).
    c) Open collector sink inputs.
    d) Wet Input (5VDC - 24VDC) with 10K resistor
    e) Any combination of the above. 
Outputs:
Power:
•  12VDC or 5VDC up to 6A, 24VDC up to 10A 
  (240W total power).
•  Overvoltage protection.
ACMS8:
•  Fuse protected outputs rated @ 2.5A per output, 
  non power-limited. Total output 6A max. 
  Do not exceed the individual power supply ratings.
ACMS8CB:
•  PTC protected outputs rated @ 2A per output, 
  Class 2 power-limited. Total output 6A max.
  Do not exceed the individual power supply ratings.
•  Eight (8) selectable independently controlled 
  outputs or eight (8) indepently controlled 
  Form “C” relay outputs (see below for ratings): 
    a) Fail-Safe and/or Fail-Secure power outputs. 
    b) Form “C” relays rated @ 2.5A. 12, 24VDC, 
      0.6 Power Factor (ACMS8 only).
    c) Auxiliary power outputs (unswitched).
    d) Any combination of the above. 
•  Individual outputs may be set to OFF position for 
  servicing (output jumper set to middle position).
  Does not apply to Dry Contact applications.
•  Any of the eight (8) fuse/PTC protected power 
  outputs are selectable to follow power Input 1 or 
  Input 2. Output voltage of each output is the same 
  as the input voltage of the input selected.
•  Surge suppression.
Fuse/PTC Ratings:
AL1024ULXB2:
 - Input fuse is rated 5A/250V. 
 - Battery fuse rated 15A/32V. 
ACMS8:
 - Main input fuse is rated 15A/32V.
 - Output fuses are rated 3A/32V.
ACMS8CB:
 - Main input PTC is rated 9A.
 - Output PTCs are rated 2A.
Battery Backup:
•  Built-in charger for sealed lead acid or
  gel type batteries.
•  Automatic switch over to stand-by battery
  when AC fails.
•  Maximum charge current 3.6A.
•  Zero voltage drop when switched over to 
  battery backup.
Supervision:
•  AC fail supervision (form “C” contacts). 
•  Low battery supervision (form “C” contacts). 
•  Battery presence supervision (form “C” contacts).
Fire Alarm Disconnect:
•  Fire Alarm disconnect (latching or non-latching) is 
  individually selectable for any or all of the 
  eight (8) outputs.
  Fire Alarm disconnect input options: 
    a) Normally open [NO] or normally closed [NC] 
      dry contact input. Polarity reversal input from 
 FACP signaling circuit. 
•  FACP input WET is rated 5-30VDC 7mA.
•  FACP input EOL requires 10K end of line resistor.
•  FACP output relay [NC]: 
  Either Dry 1A/28VDC, 0.6 Power Factor or 
  10K resistance with [EOL JMP] intact.
Visual Indicators:
AL1024ULXB2:
•  Green AC LED:  Indicates 115VAC present.
•  Red DC LED:  Indicates DC output.
ACMS8(CB):
•  Red LEDs:      Indicate outputs are triggered.
•  Blue LED:     Indicates FACP disconnect 
       is triggered.
•  Individual     
  Voltage LEDs:    Indicate 12VDC (Green) or 
       24VDC (Red).
Environmental:
•  Operating temperature: 0ºC to 49ºC ambient.
•  Humidity: 20 to 85%, non-condensing.
Enclosure Dimensions (approximate H x W x D):
  15.5” x 12” x 4.5” 
  (393.7mm x 304.8mm x 114.3mm).
