Altronix M220 Series Multi-Output Access Control Power Supply Installation Guide

Altronix M220 Series Multi-Output Access Control Power Supply

Overview:

Altronix M220 Series multi-output access control power supply/chargers are specifically designed for use with access control systems and accessories. These units convert a 220VAC (working range 198VAC – 256VAC), 50/60Hz input into five (5) individually protected 12VDC or 24VDC outputs (see specifications). Each output will route power to a variety of access control hardware devices including Mag Locks, Electric Strikes, Magnetic Door Holders, etc. These outputs will operate in both Fail-Safe and Fail-Secure modes. Controlled trigger input is achieved through normally open [NO] or normally closed [NC] supervised input or the polarity reversal from an FACP (Fire Alarm Control Panel). A form “C” dry output relay enables HVAC Shutdown, Elevator Recall or may be used to trigger auxiliary devices.

Installation Instructions:

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

1. Mount unit in the 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 three 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. 15, 16). Secure enclosure to earth ground. It is recommended to first review the following tables for screw terminals, switch selection and LED status indications. This will greatly facilitate installation hook-up. Carefully review: Output Voltage & Stand-by Specifications (pg. 5) Terminal Identification Table (pg. 10) LED Diagnostics (pg. 4) Typical Application Diagrams (pgs. 11 & 12)

2. Set output voltage: AL300M220, AL400M220 (Fig. 1c, pg. 5) and AL600M220 (Fig. 2c, pg. 6): set desired DC output voltage by setting switch SW1 to the appropriate position on the power supply board. AL1012M220 is 12VDC only. AL1024M220 is 24VDC only. (Output Voltage and Stand-by Specification Charts, pg. 5).

3. Secure green lead (earth ground) to ground lug. Connect AC power (115VAC, 60Hz) to the terminals marked [L, G, N] on power supply board (Figs. 1 – 4, pgs. 6 – 9). Use 18 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).

4. Measure output voltage before connecting devices. This helps avoiding potential damage. Keep power-limited wiring separate from non power-limited wiring (220VAC, 50/60Hz 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.

5. Connect Fail-Secure type locking hardware (e.g. door strikes and electronic dead bolts) positive leads to terminals marked [1] through [5] [POS. (+) DC OUTPUT (ALARM)] on MOM5 board and the negative leads to terminals marked [NEG 1] through [NEG 5] on MOM5 board (Figs. 1 – 4, pgs. 6 – 9).

6. Connect Fail-Safe type locking hardware (e.g. mag locks, door strikes and door holders) positive leads to terminals marked [6] through [10] [POS. (+) DC OUTPUT (STAND-BY)] on MOM5 board and negative leads to terminals marked [NEG 1] through [NEG 5] on MOM5 board (Figs. 1 – 4, pgs. 6 – 9).

7.  To trigger the unit from a FACP connect signaling circuit of FACP to terminals marked [– INPUT +] on MOM5 board (Figs. 1 – 4, pgs. 6 – 9). Polarity is shown in alarm condition. For latching fire alarm interface see Fig. 7, pg. 11; Figs. 8 & 9, pg. 12.
   Note: A 2.2K EOL must be installed across terminals marked [TRIGGER] on MOM5 board or the unit will remain in an alarm condition.

8. To trigger the unit using a supervised dry contact connect the 2.2K resistor in series for a [NC] trigger input and in parallel for [NO] trigger input (Fig. 5, pg. 11).

9. Connect auxiliary devices triggered by the unit to the terminals marked [DRY OUTPUT NO & C] on MOM5 board for normally open output or terminals marked [DRY OUTPUT NC & C] on MOM5 board for normally closed output (Figs. 1 – 4, pgs. 6 – 9).
   Note: This relay will energize when the unit is triggered.

10.  For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in the loss of output voltage. Batteries must be lead acid or gel type if used. Connect one (1) 12VDC battery to terminals marked [+ BAT –] on power supply board for 12VDC operation (Figs. 1 – 4, pgs. 6 – 9).
    Use two (2) 12VDC batteries connected in series for 24VDC operation. (Battery leads included).

11. Connect supervisory trouble reporting devices to outputs marked [AC FAIL, LOW BAT] and [Power Fail] supervisory relay outputs marked [NO, C, NC] on power supply board (Figs. 1a – 4a, pgs. 6 – 9). Use 22 AWG to 18 AWG for AC Fail & Low Battery reporting.
    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 for 6 hours cut “AC Delay” jumper (Figs. 1b – 4b, pgs. 6 – 9).

12. Please ensure that the cover is secured with the provided Key Lock.

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 (Output Voltage and Stand- by Specification Charts, pg. 4). Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage at the battery terminals and at the board terminals marked [– BAT +] to ensure that there is no break in the battery connection wires.
Note: AL300XB2V, AL400XB2V, AL600XB220 and AL1012XB220 (Power Supply Board) maximum charge current is 0.7A.
AL1024XB2V (Power Supply Board) maximum charge current is 3.6A.

MOM5 – Output Module

TRIGGER

| Dry normally open [NO] or normally closed [NC] supervised (2.2K EOL resistor) input trigger. A short or open circuit will transfer power from terminals marked [POS. (+) DC OUTPUT (STAND-BY)] to terminals marked [POS (+) DC OUTPUT (ALARM)].

– INPUT +

| Wet (5-30VDC) input trigger. Applying voltage to these terminals in the polarity shown will transfer power from terminals marked [POS. (+) DC OUTPUT (STAND-BY)] to terminals marked [POS. (+) DC OUTPUT (ALARM)] (e.g. fire alarm control panel indications circuit).
NEG. 1

through NEG. 5

| Supplies constant negative (–) voltage.
POS. (+) DC OUTPUT (ALARM) 1-5| Supplies positive (+) voltage when dry trigger input or fire alarm wet trigger input is applied.
POS. (+) DC OUTPUT (STAND-BY) 6-10| Supplies positive (+) voltage in normal condition. Power is removed when dry trigger input or fire alarm wet trigger input is applied.
NC, C, NO DRY OUTPUT| When the MOM5 is triggered the terminals marked [C and NO] will open and the terminals marked [C and NC] will close. This output is used to trigger auxiliary devices. (e.g. HVAC Shutdown, Elevator Recall etc.). Contact rating 1A @ 28VDC.

NC, C, NO POWER FAIL

| Form “C” contacts used for reporting no voltage is present at [– DC INPUT +] terminals. Under normal conditions, terminals marked [NO and C] are open, [NC and C] are closed. A loss of power causes terminals marked [NO and C] to close and [NC and C] to open. Contact rating 1A @ 28VDC.
