Securitron AQL4-E1 – Frequently Asked Questions

1) Will the Securitron AQL4 power supply run both 12V and 24V locks, or do I have to pick one?
The AQL4 is field selectable between 12 VDC and 24 VDC on the main output, so one board covers either lock voltage, but the main output is one voltage at a time. It delivers 4 Amp at 12 VDC or 3 Amp at 24 VDC. If you need both voltages out of the same supply, order it with the B100 secondary voltage module, which adds a second selectable 12 or 24 VDC output. OutSmart dual-color LEDs show which voltage is set (green for 12 V, blue for 24 V) so you don't push 24 V into a 12 V strike.
2) How many door locks can a Securitron AQL4 power?
Budget by current, not door count. The AQL4 gives you 4 Amps total at 12 VDC or 3 Amps at 24 VDC, and everything on it shares that. Add up the holding current of every mag lock, strike, and electrified lock on the run and stay under that figure. On distribution, the board expands to 16 outputs in the standard enclosure using R8 relay modules, so the limit you hit first is almost always amperage, not the number of output points.
3) What do the R8, 2R8 and 3R8 options add to a Securitron AQL power supply?
R8 modules are the fused, relay-controlled output boards that split the supply into individually switched outputs. You can order the AQL4 with none, one (R8), two (2R8), or three (3R8) modules fitted. Order none if you're feeding a single load straight off the board; order R8 modules when each opening needs its own switched, protected output. The R8 is also what lets the built-in Fire Alarm Interface drop power on a per-output basis instead of killing the whole main output, so if some doors must release on alarm and others must not, you need R8 modules.
4) Do I need the E1 enclosure with the Securitron AQL4, or can I buy the board by itself?
Both ways are orderable. Board only suits dropping the AQL4 into an existing access control cabinet or equipment rack you already have. Board with the E1 enclosure is the standalone install, and that cased assembly measures 14 inches H x 12 inches W x 4.5 inches D, which is the footprint to check against your wall space before committing. The 16-output expansion capacity is quoted for the standard enclosure.
5) Does the Securitron AQL4 release mag locks on a fire alarm signal?
Yes, the Fire Alarm Interface is integrated on the AQL4 board, no add-on relay needed. It can shut down the main output entirely, or, when R8 output modules are fitted, disconnect on a per-output basis so you can drop the mag locks on the egress path and leave the rest of the openings powered.
6) Does the Securitron AQL4 keep the locks working during a power outage?
It switches to battery instantly on AC loss, with no dropout at the openings. Charging runs on a separate dedicated fast-charge circuit (LockSafe), which keeps charging heat off the lock output and prolongs battery life, and a low battery cutoff disconnects before the batteries go into deep discharge. Batteries themselves are a separate order item, sized to the runtime you need against the 4 Amp at 12 VDC or 3 Amp at 24 VDC load.
7) I only need to power one electric strike, is there something smaller than the Securitron AQL4?
For a single strike or a single mag, the AQL4's 4 Amp at 12 VDC output and 16-output expansion capability is more supply than the opening needs. Smaller dual-voltage options include the SDC 620 Series, a 1 amp regulated and filtered low voltage power supply with dual voltage selection, and the SDC 632 Series at 2 amps with the same dual voltage selection. The Adams Rite PS-1 is a 1 amp regulated supply at 12/24 volts DC with battery backup, and the Von Duprin PS902 is a 2A 12/24 VDC base power supply that is field selectable for access control. Any of those will carry one or two devices; step up to the AQL4 when you need the multiple fused outputs, the dedicated battery charger, or the network monitoring.
8) What is the closest 4 amp alternative to the Securitron AQL4 power supply?
The Securitron AQL4 delivers 4 Amp at 12 VDC or 3 Amp at 24 VDC from a switching supply, and the closest match on output is the SDC 634 Series, a 4 amp regulated and filtered low voltage power supply with dual voltage selection. Both give you a field-selectable 12 or 24 volt rail at 4 amps. The difference is in the topology and the expansion: the AQL4 is a switching design that is expandable up to 16 outputs in the standard enclosure and can be ordered with one, two, or three R8 power relay modules, while the SDC 634 is a regulated and filtered linear-style unit. If you are powering a bank of strikes or mags that each need their own fused, fire-alarm-releasable output, the AQL4 with R8 modules is the one built for it; if you need a single 4 amp dual-voltage rail feeding one or two devices, the 634 covers it.
9) What do I use instead of a Securitron AQL4 if I need more than 4 amps?
When the door count pushes the load past what the AQL4's 4 Amp at 12 VDC or 3 Amp at 24 VDC will carry, two options in the same class go higher. The Altronix AL1024ULACMCB is a power supply and access power controller with 24VDC at 10A and 8 PTC outputs in a grey enclosure, taking 115VAC 60Hz at 4.2A on the input. The BEST PS161-6 is a 6A supply with 120V input and 12/24V output, built for delayed egress exit devices. The Altronix is single voltage at 24VDC, so if the job needs a 12 volt rail as well you would either use the BEST unit or run a second supply.
10) What is the difference between the Securitron AQL4 and the RCI DKPS-2A?
Both are multi-output dual voltage supplies for access control. The RCI DKPS-2A gives 12/24VDC at 2A across 8 outputs. The Securitron AQL4 gives 4 Amp at 12 VDC or 3 Amp at 24 VDC and expands up to 16 outputs in the standard enclosure using R8 relay modules, ordered as one, two, or three modules. The AQL4 also carries a dedicated fast battery charger, an integrated Fire Alarm Interface that can drop the main output or disconnect per output when R8 modules are fitted, and optional Netlink network monitoring with event recording and email fault reporting. Choose on door count and whether the site wants the supply reporting back over the network.
11) Can I monitor an access control power supply over the network and get an email if it fails?
That is what the AQL4 is built for. With the optional Netlink module it reports over the network: AC line voltage monitoring, remote battery monitoring and testing, email fault reporting, and 1000 events of onboard data recording. For a facilities or MRO team running doors across several buildings, that turns a dead battery into an email instead of a service call after the fact. The Netlink module is a separate order.
12) What input voltage does the Securitron AQL4 take, and can it run on 230V?
Input is 120 or 230 VAC, so the same AQL4 works on North American and 230 V service. Efficiency runs up to 91%, which is the practical difference against a linear supply: less waste heat inside the cabinet on a fully loaded board.
13) Can I install a Securitron AQL4 power supply in an unheated garage or a parking structure?
The AQL4 is specified for operation from 0 to 49 degrees C. That covers a conditioned electrical room, a corridor, or a sheltered garage in most climates, but it is not rated to run below freezing, so an exposed exterior cabinet or an unheated northern-climate structure is outside spec. It is a commercial-rated unit, not a residential one.
14) Which model do I order, and what do I have to specify on a Securitron AQL power supply?
The model is SEC-AQL4 in the AQL Series. Three choices build the part: enclosure (board only, or board with the E1 enclosure), power relay modules (none, R8, 2R8, or 3R8), and the B100 secondary voltage module (yes or no). Every combination of those three is orderable, 16 in total. Decide the modules up front against your output count and whether you need a second voltage, since that is what sets the board you receive.
15) What is the difference between the Securitron AQL4 and the SDC 631?
The SDC 631 Series is a 1.5 amp regulated and filtered DC power controller with dual voltage selection, and the SDC 632 Series is the 2 amp version with the same dual voltage selection. The Securitron AQL4 sits above both on output at 4 Amp at 12 VDC or 3 Amp at 24 VDC and is a switching supply rather than a regulated and filtered linear one, with up to 91% efficiency, low battery cutoff, enhanced surge immunity, and 1000 event data recording with the network module. Match the amp draw of the connected hardware first; the SDC units suit a small door count, the AQL4 suits a panel serving many openings that also needs battery standby and monitoring.
16) Can I power a motorized latch retraction exit device from a Securitron AQL4?
Motorized latch retraction is a different load profile from a strike or a mag, and it is worth matching the supply to it. The BEST RPSMLR2 Series is a power supply built specifically for motorized latch retraction exit devices, and the BEST PS161-6 is built for delayed egress exit devices at 6A with 12/24V output. The AQL4 is a general-purpose dual voltage switching supply rated 4 Amp at 12 VDC or 3 Amp at 24 VDC with a fire alarm interface and expandable outputs; confirm the inrush and hold current your exit device manufacturer publishes against that 4 amp figure before you commit to it for MLR.
17) Is the Aiphone AC-PS1250 a substitute for the Securitron AQL4?
They are not interchangeable. The Aiphone AC-PS1250 is a 12V DC 5A UL listed power supply for AC Series access control kits, so it is a single-voltage unit tied to that Aiphone system. The Securitron AQL4 is field selectable for 12 or 24 VDC at 4 Amp and 3 Amp respectively, with OutSmart dual-color LED indication (green for 12 V, blue for 24 V) to prevent applying the wrong voltage, and expands to 16 outputs. If your locks are 24 volt, or you are mixing 12 and 24 volt devices on one panel with the B100 secondary voltage module, the Aiphone unit will not do the job.
18) Do I need a Securitron AQL4 or a logic controller like the Detex 10-800?
These solve different halves of the same opening. The Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC power supply and battery backup, so the sequencing logic and the power come in one box. The Securitron AQL4 is a power supply: 12 or 24 VDC field selectable at 4 Amp and 3 Amp, with an integrated Fire Alarm Interface for main output shutdown or per-output disconnect when R8 modules are fitted, and Netlink network monitoring as an option. If the door needs delay and sequencing logic, the Detex controller carries that; if you already have a controller or access panel making the decisions and simply need clean, monitored, battery-backed DC to the hardware, the AQL4 is the piece.
19) What 24 volt only supply can I use if I do not need the 12 volt output of the Securitron AQL4?
If every device on the panel is 24 volt, the AQL4's field-selectable 12/24 VDC capability and B100 secondary voltage module are capability you will not use. Straight 24 VDC options include the Command Access PS1 Series, a 24VDC linear power supply with 1 amp output; the Command Access PS204/204B at 2A 24VDC with battery backup; and the Command Access PS210, a UL 6E/CSA linear supply at 1.5A 24VDC with boost circuitry. The Altronix AL1024ULACMCB goes to 24VDC at 10A with 8 PTC outputs for larger 24 volt loads. Size to your total 24 volt draw and to how many separately protected outputs the job needs.
20) Is the ROFU 10305-LA power transfer hinge an alternative to the Securitron AQL4?
No. The ROFU 10305-LA/10306-LA is a tamper resistant power transfer hinge rated 1.5A at 42V in a plastic white finish, which is the device that carries wire from the frame into a moving door leaf. The Securitron AQL4 is the supply that generates the DC in the first place, 4 Amp at 12 VDC or 3 Amp at 24 VDC from 120 or 230 VAC input. On an electrified opening you will commonly need both: the AQL4 in the closet or above the door, and a power transfer hinge or loop at the door itself.
21) What can I use in place of a Securitron AQL4 for a straightforward 12 volt access control panel?
For a plain 12 volt panel without network monitoring, the ROFU 9102-12D UL is a power supply with 10/120VAC 60Hz input, offered alongside the 9102-24D for 24 volt work. The Aiphone AC-PS1250 is a 12V DC 5A UL listed unit if the system is an Aiphone AC Series access control kit. The Securitron AQL4 earns its place when the panel needs both voltages, multiple fused outputs up to 16, a dedicated fast battery charger, and the fire alarm interface that drops outputs on alarm.
22) Is the Command Access CAT Field Tester a replacement for a Securitron AQL4 on the job?
No, it is a bench and field tool rather than an installed supply. The Command Access CAT Field Tester is a 12-24VDC portable power supply that runs off DeWalt, Makita and Milwaukee batteries, used to power up and verify hardware before or during installation. The Securitron AQL4 is the permanent commercial supply for the opening, taking 120 or 230 VAC input in a 14 inch by 12 inch by 4.5 inch enclosure with battery backup and instant auto-switch on AC loss. Many installers carry the field tester to prove a lock works and then wire the AQL4 as the fixed source.
