Altronix AL1024NKA8 Series Installation Manual page 2

Altronix AL1024NKA8 and AL1024NKA8D distribute and switch power to access control systems and accessories.
They convert a 115VAC 60Hz input into eight (8) independently controlled 12VDC or 24VDC protected outputs.
Access Power Controller's dual input design allows power to be steered from two (2) factory installed independent
low voltage 12 or 24VDC Altronix power supplies to eight (8) independently controlled fuse (AL1024NKA8) or PTC
(AL1024NKA8D) protected outputs. Power outputs can be converted to dry form "C" contacts. Outputs are activated
by an open collector sink, normally open (NO), normally closed (NC) dry trigger input, or wet output from an Access
Control System, Card Reader, Keypad, Push Button, PIR, etc. AL1024NKA8(D) will route power to a variety of access
control hardware devices including Mag Locks, Electric Strikes, Magnetic Door Holders, etc. Outputs will operate
in both Fail-Safe and/or Fail-Secure modes. The FACP Interface enables Emergency Egress, Alarm Monitoring, or
may be used to trigger other auxiliary devices. The fire alarm disconnect feature is individually selectable for any or
all of the eight (8) outputs. The spade connectors allow you to daisy chain power to multiple ACMS8(CB) modules.
This feature allows you to distribute the power over more outputs for larger systems.

A. AL1024NKA8(D) internal current consumption
B. Load current consumption
C. Stand-by time required (hours)
D. Battery capacity required for stand-by
E. AL1024NKA8(D) internal power consumption
F. Load current consumption
G. Alarm duration (Hours; 15 Min. = 0.25 Hour)
H. Battery capacity required for Alarm
I. Total calculated battery capacity
J. Battery capacity required
Note: AL1024NKA8(D) power supply is designed to work with batteries up to 65AH.
Please note: line [I] must not exceeds 36AH.
You have to reduce either stand-by current consumption or stand-by time in order to comply with requirement.
To determine actual battery size please round line [J] to the nearest larger standard battery size
(e.g. 3.5 AH = 4.0 AH).
