Altronix AL1024ULM – Frequently Asked Questions

1) Can the Altronix AL1024ULM power 12VDC mag locks or strikes?
No. The AL1024ULM is a 24VDC-only supply, rated 10A across five outputs. There is no field-selectable 12V setting on it. If your locks are 12VDC, look at a dual-voltage or 12V supply instead, such as the Securitron AQS1210 (12 VDC, 10 Amp) or the Von Duprin PS902, which is field selectable 12/24 VDC at 2A. Mixing a 24V supply into a 12V device will damage it.
2) How many doors can one Altronix AL1024ULM run?
Five separately protected outputs, each PTC protected and rated at 2A, with 10A total supply current at 24VDC. So five devices max on the board without adding a distribution module, and each one has to stay under 2A. Practically, the limit you hit first is usually the 10A total: five 2A draws would sit right at the ceiling. The PTCs are auto-resettable, so a shorted lock on one door trips that output and restores itself once the fault clears instead of taking the whole panel down.
3) Does the AL1024ULM drop power to mag locks on a fire alarm signal?
That's what the fire alarm disconnect is for. The AL1024ULM takes a trigger from a fire alarm control panel either as a supervised normally open or normally closed input, or as a polarity reversal input from the FACP. When it triggers, power to the outputs is interrupted so fail-safe locks release. It also carries a form C dry output relay that energizes on trigger, which you can use for HVAC shutdown, elevator recall, or firing an auxiliary device. That relay is rated 1A at 28VDC.
4) Will the Altronix AL1024ULM work with fail-secure electric strikes as well as fail-safe mag locks?
Both. The outputs operate in fail-safe and fail-secure modes, and they'll feed mag locks, electric strikes, and magnetic door holders. Keep in mind what the fire alarm disconnect actually does on each: cutting power releases a fail-safe mag lock, but a fail-secure strike stays locked when power drops. On an egress door tied to the fire alarm, you want the fail-safe device on the disconnected output.
5) Does the Altronix AL1024ULM include a battery for backup power?
Batteries are sold separately. The charger is built into the unit for sealed lead acid or gel type batteries, and what ships is the enclosure, the charger, and the five PTC Class 2 outputs. On AC failure it switches over automatically with zero voltage drop, so locks and readers don't blink. You'll need to size and buy the standby batteries against your own runtime requirement.
6) What is the closest 10 amp alternative to the Altronix AL1024ULM for a 12VDC access control job?
The AL1024ULM supplies 24VDC at 10A across five PTC protected Class 2 power limited outputs rated 2A each, so it only serves 24 volt hardware. When the locks on the opening are 12 volt, the Securitron AQS1210 switching power supply is the matching capacity choice at 12 VDC 10 Amp. Verify the coil voltage of every mag lock and strike on the run before choosing between them, since the AL1024ULM has no 12 volt selection.
7) What should I use instead of the Altronix AL1024ULM when the system needs to run at either 12 or 24 volts?
The AL1024ULM is a fixed 24VDC unit rated at 10A. For an opening where the voltage is not settled or the hardware mixes, a field selectable supply covers both: the Von Duprin PS902 base power supply is 2A 12/24 VDC field selectable for access control, and the Securitron AQL4 switching power supply gives 12/24VDC at 4/3 Amp. Both operate at far lower current than the 10A the AL1024ULM delivers, so they suit a few openings rather than a large multi-door run.
8) Is the Detex 10-800 an alternative to the Altronix AL1024ULM for a fire alarm tied opening?
They are different devices that overlap. The AL1024ULM takes a fire alarm control panel trigger through an N.O. or N.C. supervised input or polarity reversal, and carries a form C dry output relay for HVAC shutdown or elevator recall, on top of powering five 24VDC outputs. The Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC power supply and battery backup, meaning the logic and the power live in one unit. Choose the Altronix when the panel or access system supplies the logic and you need distributed 24 volt power at 10A; choose the Detex when the opening needs the controller itself.
9) What input power does the AL1024ULM need at the panel, and what breaker circuit should the electrician run?
Standard 115VAC 60Hz single phase, drawing 4.2A, with a 3.5A/250V input fuse on the board. The listed product voltage is 120V, so a normal building branch circuit feeds it. For load calculations the system AC input requirement is 483VA and heat rejection is roughly 123 BTU/hr, which matters if you're stacking several of these in a closed IT or riser closet.
10) Can I get a trouble signal at the head end if the AL1024ULM loses AC or the battery goes bad?
Yes, on four separate form C contact sets: AC fail supervision, low battery supervision, battery presence supervision, and a power fail supervision relay. Wire those dry contacts back to a monitored input on your access control panel or alarm system. The AC fail notification delay is selectable at 30 seconds (how it ships from the factory) or 6 hours, so you can choose whether a brief utility blip pages someone or whether you only hear about a genuine sustained outage.
11) Is the Altronix AL1024ULM rated to run in an unconditioned electrical or riser closet?
Operating range is 0 to 49 C (32 to 120 F) with relative humidity of 85 percent plus or minus 5. Storage tolerance is wider, -20 to 70 C (-4 to 158 F). That covers a typical interior riser or IT closet, but an unheated exterior vestibule or a rooftop penthouse in a cold climate can drop below the 32 F floor, and battery capacity suffers there too.
12) Is a 10 amp access control power supply overkill, or should I use a smaller 1 or 2 amp unit?
Size it to the door count. The AL1024ULM at 24VDC 10A with five outputs is built for a multi-door access control system where one enclosure feeds a bank of locks and you want per-door fault isolation. For a single opening or a small two-door job, a 1 to 2 amp supply is the right tool and takes less wall space: the Command Access PS1 is a 24VDC linear supply with 1 amp output, the Command Access PS204/204B gives 2A at 24VDC with battery backup, and the SDC 632 Series is a 2 amp regulated and filtered supply with dual voltage selection. Where you need more headroom but not ten amps, the BEST PS161-6 runs 120V in, 12/24V out, at 6A.
13) Will the AL1024ULM run motorized latch retraction exit devices or delayed egress hardware?
Motorized latch retraction and delayed egress are special cases, and the AL1024ULM is a general purpose 24VDC access control supply rather than a device built around them. MLR devices draw a heavy inrush and are normally fed from a supply matched to that hardware, like the BEST RPSMLR2 Series, made for motorized latch retraction exit devices. For delayed egress, the BEST PS161-6 is the supply intended for delayed egress exit devices. Use the AL1024ULM for mag locks, electric strikes, and door holders, which is what its outputs are described for.
14) Are the AL1024ULM outputs power limited for Class 2 wiring?
All five outputs are Class 2 rated and power limited, individually PTC protected at 2A. That's what lets the low voltage side be run as Class 2 wiring. The outputs are filtered and electronically regulated with short circuit and thermal overload protection, so a pinched lock lead on one door doesn't drag down the other four.
15) I only have one or two doors. Is there a simpler option than the Altronix AL1024ULM?
The AL1024ULM is built for multi-door work: five individually protected Class 2 outputs and 10A of 24VDC supply current, with a built-in charger and an enclosure. A single strike or mag lock does not need that. The Command Access PS1 is a 24VDC linear power supply with 1 amp output, and the Command Access PS210 is a UL 6E/CSA linear supply with 1.5A at 24VDC and boost circuitry. The SDC 620 Series is a 1 amp regulated and filtered low voltage supply with dual voltage selection. All three stay at 24 volts like the AL1024ULM but carry a fraction of the load and none of its output count.
16) Which power supply gives me multiple protected outputs like the Altronix AL1024ULM but at lower current?
The AL1024ULM distributes 24VDC at 10A over five PTC protected outputs rated 2A each. The RCI DKPS-2A is the other multi-output unit in the class, with 8 outputs at 12/24VDC and 2A for access control systems. The RCI adds 12 volt operation and more output positions; the Altronix carries the higher total supply current. Size by the sum of the lock currents on the run, not by the number of doors.
17) Can I use a BEST PS161-6 or an SDC 634 in place of the Altronix AL1024ULM?
Both are 24 volt capable but neither reaches the AL1024ULM's 10A of supply current. The BEST PS161-6 is a 120V input, 12/24V output supply with 6A capacity intended for delayed egress exit devices, and the SDC 634 Series is a 4 amp regulated and filtered low voltage supply with dual voltage selection. Either covers a smaller run at 24 volts; a bank of mag locks totaling more than their rated capacity needs the AL1024ULM's 10A.
18) Does a Command Access PS204/204B do the same job as the Altronix AL1024ULM since both have battery backup?
Both hold up a system when AC drops, but at different scales. The AL1024ULM has a built-in charger for sealed lead acid or gel batteries with automatic switch over and zero voltage drop, feeding five outputs at 24VDC and 10A. The Command Access PS204/204B is a linear power supply with 2A at 24VDC and battery backup. Same voltage and the same backup idea; the Command Access unit carries a single small load and the Altronix carries a multi-door bank. Batteries are sold separately for the AL1024ULM.
19) Are the ROFU 10305-LA and the Command Access CAT Field Tester substitutes for an Altronix AL1024ULM?
Neither one powers an installed access control system. The ROFU 10305-LA/10306-LA is a power transfer hinge rated 1.5A at 42V, which is how power crosses from the frame to the door leaf, not the source of that power. The Command Access CAT Field Tester is a portable 12-24VDC supply that runs off DeWalt, Makita and Milwaukee batteries for bench and field testing. The AL1024ULM is the permanent 115VAC fed unit that converts to five 24VDC outputs at 10A. A job may use the hinge alongside it, but not in place of it.
20) I need a UL listed supply for an access control kit. Is the Aiphone AC-PS1250 interchangeable with the Altronix AL1024ULM?
They serve different voltages and different scopes. The Aiphone AC-PS1250 is a UL listed 12V DC 5A supply for AC Series access control kits, so it is matched to that kit's hardware. The AL1024ULM produces 24VDC at 10A on five Class 2 rated power limited outputs and adds a form C dry output relay rated 1A at 28VDC for HVAC shutdown or elevator recall. If the devices are 12 volt kit components, the Aiphone is the fit; if the system is 24 volt with fire alarm interface, the Altronix is.
21) What is the difference between the Altronix AL1024ULM and the BEST ELR150 for controlling power to a lock?
The BEST ELR150 Series is a power supply control module for electronic access control, a module that manages the power going to a device. The AL1024ULM is the source itself, converting 115VAC 60Hz at 4.2A into five individually protected 24VDC outputs at 10A, with an input fuse rated 3.5A/250V and filtered, electronically regulated output carrying short circuit and thermal overload protection. A control module needs a supply behind it; the Altronix is that supply.
22) Can the ROFU 9102 stand in for the Altronix AL1024ULM on a 24 volt door?
The ROFU 9102-12D UL/9102-24D is a power supply with a 10/120VAC 60Hz input and is offered in 12 and 24 volt versions, so the 24 volt version matches the AL1024ULM's output voltage and both run off a 120V feed. What the Altronix adds is the distribution and the interface: five separately protected Class 2 outputs at 2A each totaling 10A, fail-safe and fail-secure operation, and a fire alarm panel trigger input.
23) Does the Altronix AL1024ULM come with an enclosure or do I have to buy a cabinet?
The grey enclosure is included, along with the charger and the five PTC Class 2 outputs. No separate cabinet purchase. There are AC input and DC output LEDs on the power supply board, plus red LEDs on the multi-output board showing the condition of each power output and the input trigger, so a tech can read the state of every door circuit with the cover open and no meter.
24) Can a plug-in supply like the ROFU 9126T replace the Altronix AL1024ULM?
Only on a job that is nothing like the same size. The ROFU 9126T is a plug in mini power supply delivering 12 VDC at 1.5A with time delay, a single small 12 volt load on a cord. The AL1024ULM is a commercial 120V unit that includes an enclosure, a charger and five PTC Class 2 outputs at 24VDC and 10A, with AC fail, low battery and battery presence supervision on form C contacts. Different voltage, different mounting, different scale.
25) How does the Altronix AL1024ULM compare to the Locknetics LP Series for a large multi-door system?
The Locknetics LP Series is a 150 and 250 Amp power supply with enclosure, and the AL1024ULM is a 24VDC 10A supply with an enclosure and five individually protected outputs. Both are enclosure mounted units for commercial work. The AL1024ULM's distinguishing feature for a fire tied system is the trigger set: supervised N.O. or N.C. input, polarity reversal from a fire alarm control panel, and outputs that operate in both fail-safe and fail-secure modes.
26) Is a solar supply such as the Securitron BPSS an option where an Altronix AL1024ULM cannot be fed?
The AL1024ULM requires a 115VAC 60Hz feed at 4.2A and a system AC input allowance of 483VA, so it cannot serve a location without line power. The Securitron BPSS is a boxed solar power supply for that situation. Where line power is available, the AL1024ULM's 10A across five 24VDC outputs supports a full multi-door bank that a remote solar fed opening would not attempt.
27) How does the Altronix AL1024ULM differ from the Securitron AQD1 for a small retrofit?
The Securitron AQD1 is a switching power supply at 12/24 VDC 1 Amp, sized for one device and selectable between voltages. The AL1024ULM is a 24 volt only unit at 10A that adds a built-in battery charger with automatic switch over on AC failure, supervision relays for AC fail, low battery and battery presence, and LED indication of each output's condition. A retrofit of one strike does not need that supervision; a monitored system does.
