Securitron AQD2 – Frequently Asked Questions

1) Can the Securitron AQD2 power supply run both 12VDC and 24VDC locks, or do I have to pick one when I order?
One part covers both. The AQD2 is field selectable between 12 VDC and 24 VDC continuous output, so you set the voltage at install rather than at the order desk. What you cannot do is run 12V devices and 24V devices off the same board at the same time, since the selection applies to the whole supply. Mixed-voltage openings need a second supply.
2) How many maglocks or electric strikes will a 2 amp Securitron AQD2 actually power?
The AQD2 gives you 2 amps continuous, at either 12 or 24 VDC, and that total is what you budget against. Add the holding current of every device on the supply, at the voltage you have selected, and stay under 2 amps with headroom for inrush on strikes and motorized latch retraction. Latch retraction devices in particular pull far more on the pull-in than they hold at, so they usually want a dedicated supply rather than a share of this one. If your load sheet comes out over 2 amps, step up rather than paralleling supplies.
3) Does the Securitron AQD2 support battery backup for locks during a power outage?
Yes, and the charger is built in. The AQD2 has an integrated battery charging circuit and supports up to two sealed gel, AGM or wet lead acid batteries. The charging circuit is designed to keep overvoltage off the locking devices while charging, which matters when the batteries sit on the same rails as your maglocks. Batteries are a separate purchase.
4) Does the AQD2 have a fire alarm relay to drop the locks on alarm?
The AQD2 as catalogued here carries no fire alarm relay. The AQD family is available with a single relay fire trigger or with individually triggered relayed outputs, but that is a different configuration than this one. If your maglocks have to release on fire alarm and you want that done at the supply, specify an AQD variant with the fire trigger rather than this unit.
5) Is the Securitron AQD2 UL listed for access control power?
UL listed, and the listing covers combinations. The AQD switching power supplies are UL listed supervised units, and all combinations of AQ power supplies and distribution boards are UL listed, so pairing the supply with an AQ distribution board does not put you outside the listing. That is the point institutional and healthcare specs usually turn on.
6) Do I need a separate distribution board to feed multiple doors from the AQD2?
Yes, if you want individually protected runs to each opening. The AQD platform supports up to 16 independently controlled power limited outputs, but those come from AQ distribution boards paired with the supply, not from the supply on its own. All combinations of AQ power supplies and distribution boards are UL listed, so adding the board keeps the assembly within the listing. If you would rather have the outputs built into one unit, the RCI DKPS-2A carries 8 outputs at 12/24VDC and 2A.
7) What is the closest equivalent to the Securitron AQD2 power supply from another brand?
The Von Duprin PS902 is the nearest match. Both are 2 amp base power supplies with field selectable 12 or 24 VDC output, so either one drops into an opening where the locking devices run on 2 amps at one of those two voltages. The AQD2 is a switching supply with an integrated battery charging circuit and 115 VAC input. If you want that same 2A dual voltage capability in a linear rather than switching design, the Command Access PS204/204B delivers 2A at 24VDC with battery backup, and the SDC 632 Series is a 2 amp regulated and filtered supply with dual voltage selection.
8) What should I use instead of the Securitron AQD2 if 2 amps is not enough for my door count?
Step up to a higher output supply. The SDC 634 Series is a 4 amp regulated and filtered low voltage supply with dual voltage selection, keeping the same 12 or 24 volt flexibility as the AQD2 at double the current. For larger loads, the BEST PS161-6 runs 120V input to 12/24V output at 6A capacity, and the Altronix AL1024ULACMCB is a power supply and access power controller with 115VAC 60Hz input at 4.2A and 24VDC at 10A across 8 PTC outputs in a grey enclosure. The AQD2 itself is rated 2 amps at either 12VDC or 24VDC continuous.
9) Can I substitute the Securitron AQD2 for a motorized latch retraction exit device power supply?
No, those are different animals. Motorized latch retraction devices draw a high inrush current at actuation and need a supply built for it, such as the BEST RPSMLR2 Series, which is made specifically for motorized latch retraction exit devices. Delayed egress exit devices are also their own case, served by the BEST PS161-6. The AQD2 is a general 2 amp dual voltage supply for access control locking devices, with an integrated battery charging circuit that prevents overvoltage on locking devices. Match the supply to the exit device requirement rather than to the voltage alone.
10) What looks like an alternative to the Securitron AQD2 but will not do the same job?
A few items in the same family are not stand-ins. The ROFU 9126T is a plug in mini power supply, 12 VDC at 1.5A with time delay, so it is a small plug pack rather than a supervised boxed supply and it does not offer a 24 volt setting. The Command Access CAT Field Tester is a portable 12-24VDC unit that runs on DeWalt, Makita and Milwaukee batteries, made for bench and field testing rather than permanent installation. The ROFU 10305-LA power transfer hinge is not a supply at all, it is a tamper resistant transfer hinge rated 1.5A at 42V that carries power through the door. The AQD2 is a hardwired 115 VAC input supply with 12 or 24 VDC field selectable continuous output.
11) What is an alternative to the Securitron AQD2 if I need multiple protected outputs for several doors?
The RCI DKPS-2A is the direct parallel: a power supply with 8 outputs at 12/24VDC and 2A for access control systems, matching the AQD2 on both current and dual voltage. The AQD2 supports up to 16 independently controlled power limited outputs and all combinations of AQ power supplies and distribution boards are UL listed. If the door count pushes the total draw past 2 amps, the Altronix AL1024ULACMCB offers 8 PTC outputs at 24VDC at 10A.
12) Can I mount an access control power supply in an unheated garage or a parking structure?
The AQD2 is rated for -4 to 122 degrees F (-20 to 50 degrees C) operating temperature, which covers an unheated garage, a stair tower, or a vestibule in most of North America. It is not a weatherproof unit, so it still needs to be inside an enclosure protected from rain and washdown. Direct outdoor exposure is out.
13) Will the AQD2 hold up on dirty building power where the voltage sags?
It runs on 115 VAC input and tolerates brownout or overvoltage of plus or minus 15 percent of nominal, so a sagging feed on a loaded riser will not drop your locks. There is also thermal shutdown with auto restart, and a circuit breaker covering overcurrent and reverse battery faults, so a miswired battery on a service call does not cost you the board. Ripple runs as low as 240 mV peak to peak, which keeps card readers and boards on the same rail quiet.
14) Switching power supply or linear for access control, which should I use?
A switching supply like the Securitron AQD2 runs cooler and more efficiently, up to 82 percent, which is why it suits a panel with several doors on it and a battery charger sharing the can. Linear supplies are the traditional choice for a single opening where simplicity matters more than heat and efficiency; the Command Access PS1 Series is a 24VDC linear unit with 1 amp output, and the Command Access PS204/204B is a 2 amp 24VDC linear supply with battery backup. If you are feeding one strike, either works. If you are feeding a bank of doors in an enclosed can, the switching unit is the one that will not cook itself.
15) Do I need an enclosure with the Securitron AQD2 or is a board only version available?
The AQD2 comes both ways, with enclosure or board only, so you can drop the board into an existing can on a retrofit or take the boxed unit for a new install. Peers differ on this. The Locknetics LP Series ships with an enclosure, and the Altronix AL1024ULACMCB comes in a grey enclosure. The ROFU 9126T is a plug in unit with no enclosure to mount at all. Confirm which form you are replacing before ordering, since a board only unit assumes you already have a suitable can and transformer feed.
16) Is there a simpler power supply than the Securitron AQD2 for a single door?
For one opening with a small load, a 1 amp supply usually covers it. The SDC 620 Series is a 1 amp regulated and filtered low voltage supply with dual voltage selection, and the Adams Rite PS-1 is a 1 amp regulated supply at 12/24 volts DC with battery backup. The Command Access PS1 Series is a 1 amp linear supply fixed at 24VDC, so it suits a 24 volt device only. The AQD2 is built for larger jobs than these, with 2 amps at 12 or 24 VDC and up to 16 independently controlled power limited outputs.
17) I need a fire alarm relay on my access control power supply - what are my options besides the Securitron AQD2?
The AQD2 board itself is supplied without a fire alarm relay, though the AQD Series is available with a single relay fire trigger or individually triggered relayed outputs. If you want the control logic built into one unit, the Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC power supply and battery backup, and the Altronix AL1024ULACMCB combines a power supply with an access power controller across 8 PTC outputs at 24VDC. The BEST ELR150 Series is a power supply control module for electronic access control.
18) How does the Securitron AQD2 compare to the SDC 631 for a 12 volt maglock?
Both give you a dual voltage selection, so either will run a 12 volt maglock. The SDC 631 Series is a 1.5 amp regulated and filtered DC power controller, while the AQD2 delivers 2 amps at 12VDC or 24VDC continuous as a switching design with tolerance for brownout or overvoltage input within plus or minus 15 percent of nominal. Size by total load: count the maglock draw plus any readers or auxiliary devices on the same supply, then pick the unit whose rating covers it with headroom.
19) Can I use the Aiphone AC-PS1250 in place of the Securitron AQD2?
Only where the load is 12 volt. The Aiphone AC-PS1250 is a UL listed 12V DC 5A supply intended for AC Series access control kits, so it gives you more current but no 24 volt option. The AQD2 is field selectable for 12 or 24 VDC continuous output and supports up to two sealed gel, AGM or wet lead acid batteries through its integrated charging circuit. If the panel or locking device on the opening is 24 volt, or you need battery standby at the supply, the AQD2 covers it and the AC-PS1250 does not.
20) Which power supply should I standardize on across a facility with both 12 and 24 volt hardware?
A dual voltage unit lets you stock one part for both. The Securitron AQD2 is field selectable between 12 and 24 VDC continuous output at 2 amps, is UL listed and supervised, and runs from -4 to 122 degrees F, so it holds up in unconditioned electrical rooms. Other dual voltage options in the same range are the SDC 632 Series at 2 amps with dual voltage selection, the SDC 634 Series at 4 amps, and the Von Duprin PS902 at 2A 12/24 VDC field selectable. Picking one voltage-flexible family reduces how many distinct supplies your techs carry.
21) Is the Securitron AQD2 a commercial-grade supply or is it fine for a house?
It is a commercial unit. The AQD2 is built for commercial access control work, with 115 VAC input, supervised UL listed operation, and a battery charger for two backup batteries. That is the specification a property manager or integrator standardizes on across a building, not a plug-in transformer for a single residential door. For a small plug-in job, the ROFU 9126T is a plug in mini power supply at 12 VDC and 1.5A with time delay.
22) What is the difference between the Securitron AQD2 and the Command Access PS210?
The Command Access PS210 is a UL 6E/CSA linear supply rated 1.5A at 24VDC with boost circuitry, so it is a fixed 24 volt unit with extra headroom for devices that need a momentary lift. The Securitron AQD2 is a switching supply, field selectable for 12 or 24 VDC at 2 amps, UL listed and supervised, running up to 82 percent efficiency with a low voltage ripple design as low as 240 mV peak to peak. Choose by whether the opening needs 12 volt capability and multiple power limited outputs, or a single fixed 24 volt feed with boost.
