Altronix AL1024NKA8 Series Dual Output Access Power Controllers Installation Guide

Altronix AL1024NKA8 Series Dual Output Access Power Controllers

Overview

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.

Installation Instructions

Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, the Canadian Electrical Code and with all local codes and authorities having jurisdiction. Product is intended for indoor use only.

1. Mount unit in desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s upper keyholes over the two upper screws, level and secure. Mark the position of the lower two holes. Remove the enclosure. Drill the lower holes and install the two fasteners. Place the enclosure’s upper keyholes over the two upper screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 12). Secure enclosure to earth ground.

2. Ensure all output jumpers [PWR1] – [PWR8] are placed in the OFF (center) position (Fig. 1, pg. 3).

3. Connect unswitched AC power (115VAC 60Hz) to terminals marked [L, N] (Fig. 4a, pg. 5). Green “AC” LED on power supply board will turn on. This light can be seen through the LED lens on the door of the enclosure. Use 14 AWG or larger for all power connections. Secure green wire lead to earth ground. Keep power-limited wiring separate from non power-limited wiring (115VAC 60Hz Input, Battery Wires). Minimum 0.25” spacing must be provided.
   CAUTION: Do not touch exposed metal parts. Shut branch circuit power before installing or servicing equipment. There are no user serviceable parts inside. Refer installation and servicing to qualified service personnel.

4. Set each output [OUT1] – [OUT8] to route power from Input 1 or 2 (Fig. 1, pg. 3).
   Note: Measure output voltage before connecting devices. This helps avoiding potential damage.

5. Turn power off before connecting devices.

6. Output options: AL1024NKA8(D) will provide up to eight (8) switched power outputs or eight (8) dry form “C” outputs, or any combination of both switched power and form “C” outputs, plus eight (8) unswitched auxiliary power outputs.

   • Switched Power outputs:
     Connect the negative (–) input of the device being powered to the terminal marked [COM].

   • For Fail-Safe operation connect the positive (+) input of the device being powered to the terminal marked [NC].

   • For Fail-Secure operation connect the positive (+) input of the device being powered to the terminal marked [NO].

   • Form “C” outputs:
     When form “C” outputs are desired, the corresponding jumper (1-8) must be placed in the OFF position (Fig. 7, pg. 9). Alternatively, the corresponding output fuse (1-8) can be removed (AL1024NKA8 only). Connect negative (–) of the power supply directly to the locking device. Connect the positive (+) of the power supply to the terminal marked [C].

   • For Fail-Safe operation connect the positive (+) of the device being powered to the terminal marked [NC].

   • For Fail-Secure operation connect the positive (+) of the device being powered to the terminal marked [NO]. Dry contacts rated @ 2.5A, 28VDC.

   • Auxiliary Power outputs (unswitched):
     Connect positive (+) input of the device being powered to the terminal marked [C] and the negative (–) of the device being powered to the terminal marked [COM]. Output can be used to provide power for card readers, keypads etc.

7. Turn main power on after all devices are connected.

8. Input Trigger options:
   
   Note: If Fire Alarm disconnect is not used, connect a 10K ohm resistor to terminals marked [GND and EOL], plus connect a jumper to terminals marked [GND, RST].
   Normally Open (NO) Input:
   Slide input control logic DIP switch into the OFF position for [Switch 1-8] (Fig. 2, on right). Connect your wires to terminals marked [+ INP1 –] to [+ INP8 –].
   Normally Closed (NC) Input:
   Slide input control logic DIP switch into the ON position for [Switch 1-8] (Fig. 2, on right). Connect your wires to terminals marked [+ INP1 –] to [+ INP8 –].
   Open Collector Sink Input:
   Connect the open collector sink input to the terminal marked [+ INP1 –] to [+ INP8 –].
   Wet (Voltage) Input Configuration:
   Carefully observing polarity, connect the voltage input trigger wires and the supplied 10K resistor to terminals marked [+ INP1 –] to [+ INP8 –].
   If applying a voltage to trigger input – set the corresponding INP Logic switch to the “OFF” position
   If removing voltage to trigger input – set the corresponding INP Logic switch to the “ON” position

9. Fire Alarm Interface options:
   
   A normally closed [NC], normally open [NO] input or polarity reversal input from FACP signaling circuit will trigger selected outputs. To enable FACP Disconnect for an output turn the corresponding DIP switch [SW1-SW8] ON. To disable FACP disconnect for an output turn the corresponding DIP switch [SW1-SW8] OFF. Switch is located directly to the left of the Fire Alarm Interface Terminals.
   Normally Open Input:
   Wire your FACP relay and 10K resistor in parallel on terminals marked [GND] and [EOL].
   Normally Closed Input:
   Wire your FACP relay and 10K resistor in series on terminals marked [GND] and [EOL].
   FACP Signaling Circuit Input Trigger:
   Connect the positive (+) and negative (–) from the FACP signaling circuit output to the terminals marked [+ FACP –]. Connect the FACP EOL to the terminals marked [+ RET –] (polarity is referenced in an alarm condition).
   Non-Latching Fire Alarm Disconnect: Connect a jumper to the terminals marked [GND, RST].

10. FACP Dry NC output:
    Connect desired device to be triggered by the unit’s dry contact output to the terminals marked [NC] and [C]. When [EOL JMP] is kept intact, the output is of 0 Ohm resistance in a normal condition. When [EOL JMP] is clipped, a 10k resistance will be passed to next device when in a normal condition.

11. Stand-by Battery Connections (Fig. 6, pg. 8):
    For U.S. Access Control applications batteries are optional. Batteries are required for Canadian installations (ULC-S319). 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. 4g, pg. 6). Use two (2) 12VDC batteries connected in series for 24VDC operation (battery leads included). Use batteries – Casil CL1270 (12V/7AH), CL12120 (12V/12AH), CL12400 (12V/40AH), CL12650 (12V/65AH) batteries or UL recognized BAZR2 and BAZR8 batteries of an appropriate rating.

12. Battery and AC Supervision outputs (Fig. 4, pg. 8):
    Connect appropriate signaling notification devices to the terminals marked [AC FAIL & BAT FAIL] (Fig. 4b, pg. 5) supervisory relay outputs. Use 22 AWG to 18 AWG for AC Fail & Low/No Battery reporting.

13. To delay reporting for up to 6 hrs., cut “AC Delay” jumper and reset power to unit (Fig. 4f, pg. 6).

14. Fire Alarm Disconnect (Fig. 4c, pg. 6):

    • To enable Fire Alarm Disconnect set DIP switch [Shutdown] to ON position.
    • To disable Fire Alarm Disconnect set DIP switch [Shutdown] to OFF position.

15. Installation of tamper switch:
    Mount UL Listed tamper switch (Altronix model TS112 or equivalent) at the top of the enclosure. Slide the tamper switch bracket onto the edge of the enclosure approximately 2” from the right side (Fig. 6a, pg. 8). Connect tamper switch wiring to the Access Control Panel input or the appropriate UL Listed reporting device. To activate alarm signal open the door of the enclosure.

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.
• Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at the battery terminal and at the board terminals marked [– BAT +] to ensure that there is no break in the battery connection wires.

Note: Maximum charging current under discharges is 3.6A.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed
