Altronix AL125UL – Frequently Asked Questions

1) Will the Altronix AL125UL run both 12VDC and 24VDC locks?
The AL125UL is field selectable between 12VDC and 24VDC, and it supplies 1A at either setting. You pick the voltage on the board, so one unit covers a 12V strike or a 24V mag lock, but it is one selection for the whole unit, not per output. If you need 12V on one door and 24V on another, that is two supplies.
2) Does the Altronix AL125UL power supply have a fire alarm disconnect for mag locks?
Yes, and it is a supervised Fire Alarm Disconnect, selectable as latching with reset or non-latching. That is the interface an AHJ looks for when a mag lock or electrified lock has to drop on fire alarm: the panel triggers the supply, the lock output cuts, and on latching mode it stays cut until someone resets it. The unit is built for applications requiring an interface with Fire Alarm Control Panels.
3) Is the Altronix AL125UL UL 294 listed for access control?
UL 294 Access Control listing is exactly what this unit is intended for, and its two outputs are Class 2 rated and power limited. For a spec that calls out a UL listed access control power supply, the AL125UL meets it on the listing data as written.
4) Is 1 amp enough to power my electric strikes and card readers off one Altronix AL125UL?
1A total is the ceiling, shared across both outputs, so the AL125UL suits a single door: one strike or mag lock on the switched output plus a reader and controller on the auxiliary. Add up the continuous draw of everything you are hanging on it. Two mag locks or a motorized latch retraction device will exceed it. The PTC devices are rated at 2.5A, but that is the protection trip point, not extra capacity.
5) What is the difference between the switched and auxiliary output on the Altronix AL125UL?
Two outputs, and they behave differently. The lock output is switched and configurable fail-safe or fail-secure, so it responds to the access control trigger input, that is where the strike or mag lock lands. The auxiliary output is unswitched, meaning it stays powered continuously, which is what a reader, keypad or controller board needs. Wiring a reader onto the switched output kills it every time the door releases.
6) Does the Altronix AL125UL come with a battery for backup power?
No battery is included. The AL125UL has a built-in charger for sealed lead acid or gel cell batteries with a maximum charge current of 400mA, and it switches over to standby battery automatically when AC fails, but you buy the battery separately. Size it to the runtime your AHJ or spec requires against the load you are drawing.
7) What are the alternatives to the Altronix AL125UL if I need more than 1 amp?
Staying at 1A but a different brand, the Securitron AQD1 is a switching 12/24VDC 1 amp supply, the SDC 620 Series is a 1 amp regulated and filtered dual voltage unit, and the Adams Rite PS-1 is a 1 amp 12/24VDC regulated supply with battery backup. Stepping up: the SDC 631 Series gives 1.5A, the Von Duprin PS902 and the SDC 632 Series give 2A at 12/24VDC field selectable, the RCI DKPS-2A gives 2A across eight outputs, and the SDC 634 Series gives 4A. Multiply your door count by the holding current of the lock before you pick.
8) Will the AL125UL run a motorized latch retraction exit device, or do I need a different supply?
The Altronix AL125UL is a 1A supply built for access control locking and fire alarm interface. Motorized latch retraction devices draw an inrush the 1A rating is not sized for; the BEST RPSMLR2 Series is a power supply made specifically for motorized latch retraction exit devices. For delayed egress exit devices, the BEST PS161-6 takes 120V input to 12/24V output at 6A capacity. Match the supply to the device family rather than the voltage alone.
9) What is the closest 1 amp 12/24VDC equivalent to the Altronix AL125UL from another brand?
The Altronix AL125UL is a 1A supply with selectable 12VDC or 24VDC outputs and a built-in charger for sealed lead acid or gel batteries. The Adams Rite PS-1 is a regulated power supply rated 1 amp at 12/24 volts DC with battery backup, and the SDC 620 Series is a 1 amp regulated and filtered low voltage supply with dual voltage selection. The Command Access PS1 Series is also a 1 amp linear supply, but it is 24VDC only rather than dual voltage, so it fits only a 24V opening. If you need battery standby with the dual voltage selection, the PS-1 is the nearest match.
10) The AL125UL is only 1 amp - what do I use when the door count needs more current?
The Altronix AL125UL supplies 1A. When the load outgrows that, the SDC 631 Series is a 1.5 amp regulated and filtered DC power controller with dual voltage selection, the SDC 632 Series is 2 amp and the SDC 634 Series is 4 amp, all with the same dual voltage selection. The Von Duprin PS902 is a 2A 12/24VDC field selectable base power supply, and the RCI DKPS-2A gives 12/24VDC at 2A across 8 outputs if you are feeding several openings from one can. For a single 12VDC run at high current, the Securitron AQS1210 is a 12 VDC 10 amp switching supply.
11) I need to power more than two locks from one supply - is the AL125UL the wrong box?
The Altronix AL125UL provides two Class 2 rated power limited outputs, one switched fail-safe/fail-secure lock output and one unswitched auxiliary output. For a multi-door head end, the RCI DKPS-2A carries 8 outputs at 12/24VDC and 2A, which distributes to several openings from a single enclosure. The Detex 10-800 Series pairs a 120VAC/24VDC power supply and battery backup with a universal logic controller if the openings also need sequencing logic rather than just power.
12) Which of these power supplies looks like a substitute for the AL125UL but is not?
Two are easy to mistake. The Command Access CAT Field Tester is a portable 12-24VDC unit that runs off DeWalt, Makita and Milwaukee batteries - it is a bench and field test tool, not a permanently installed supply. The ROFU 10305-LA/10306-LA is a power transfer hinge rated 1.5A at 42V; it carries power through the door edge and does not generate it. The Securitron BPSS is a boxed solar power supply, a different source entirely from the 115VAC 50/60Hz input the Altronix AL125UL takes.
13) Which comparable supplies are UL listed like the Altronix AL125UL?
The Altronix AL125UL is intended for applications requiring UL Listing for Access Control under UL294. Among the alternatives, the Aiphone AC-PS1250 is a UL Listed 12V DC 5A supply for AC Series access control kits, and the Command Access PS210 is a UL 6E/CSA linear supply with 1.5A at 24VDC and boost circuitry. The ROFU 9102-12D UL carries the UL designation in its 12V version. If your specification calls out both a listing and a fire alarm interface, the AL125UL is the one written for that combination.
14) What input power does the Altronix AL125UL need at the panel?
115VAC 50/60Hz at 0.5A, so a standard 120V branch circuit feeds it. Budget 55.2VA on the system AC input requirement when you are sizing the circuit or the UPS ahead of it. Heat rejection into the closet is small, roughly 6 BTU/hr at 12VDC and 6 or 12 BTU/hr at 24VDC.
15) Does the Altronix AL125UL come in an enclosure or is it a board only?
It ships as a boxed unit. The AL125UL includes the enclosure, the charger and the two PTC protected Class 2 outputs, so there is nothing else to buy to mount it apart from the standby battery. That matters if you are comparing against board-only control modules that assume you already have a can on the wall.
16) Can I mount the Altronix AL125UL in an unheated garage or a rooftop mechanical room?
Operating range is 0 to 49 degrees C (32 to 120 degrees F) at up to 85 percent relative humidity, so an unheated space that drops below freezing is outside the rating. Storage tolerates more, minus 20 to 70 degrees C, but that is shelf life, not running. For a cold parking structure or an exterior gate house, put it in a conditioned space and run the low voltage out to the door.
17) What does the LED on the Altronix AL125UL tell me when a door stops releasing?
One status LED covers four conditions: Normal, No Output, Loss of AC, and Triggered. That is a fast first check on a service call. No Output with AC present points at the supply or a tripped PTC, Loss of AC sends you to the breaker with the unit running on standby battery, and Triggered tells you the fire alarm disconnect or access control trigger input has acted rather than the lock having failed. Outputs are PTC protected with short circuit and thermal overload protection, so a shorted strike wire trips and resets itself once the fault is cleared rather than blowing a fuse.
18) What is the difference between the Altronix AL125UL and the Securitron AQD1?
Both are 1 amp supplies with 12 and 24 VDC. The Securitron AQD1 is a switching power supply at 12/24 VDC 1 amp. The Altronix AL125UL is a filtered and electronically regulated linear design that includes an enclosure, a built-in charger for sealed lead acid or gel batteries with automatic switch over to standby when AC fails, and a supervised fire alarm disconnect that can be set latching with reset or non-latching. Choose the AL125UL where the opening needs onboard battery standby and a fire alarm interface in the same can.
19) Is there a simpler option than the AL125UL for a single 12VDC strike?
For one 12V opening with no battery standby, the ROFU 9126T is a plug in mini power supply rated 12 VDC at 1.5A with a time delay built in. The ROFU 9102-12D UL/9102-24D takes 10/120VAC 60Hz input and comes in fixed 12V and 24V versions. The Altronix AL125UL brings more to the opening than either - selectable 12VDC or 24VDC, a battery charger, a switched fail-safe/fail-secure lock output and a supervised fire alarm disconnect - so the simpler units suit a standalone strike that never needs standby power or a fire alarm tie.
20) Does the AL125UL come with an enclosure or do I buy that separately?
The Altronix AL125UL ships with the enclosure, the charger and the two PTC Class 2 outputs. The Locknetics LP Series 150 and 250 amp power supply also comes with an enclosure. The BEST ELR150 Series is a power supply control module for electronic access control, a module rather than a complete boxed supply, so plan the housing accordingly when comparing the two.
21) Is a switching supply like the Securitron AQL4 interchangeable with the Altronix AL125UL?
The Securitron AQL4 is a switching power supply at 12/24VDC rated 4/3 amp, so it covers the same voltage selection at higher current than the 1A Altronix AL125UL. The AL125UL is filtered and electronically regulated with short circuit and thermal overload protection, PTC protected outputs rated at 2.5A, and a supervised fire alarm disconnect. Where the specification calls for the fire alarm interface and the onboard charger, the AQL4 does not stand in for it on those points; where it is a straight current question, the AQL4 covers a larger load.
22) Is the Altronix AL125UL suitable for a commercial building or is it a residential unit?
This is commercial grade access control power. Filtered and electronically regulated output, UL 294 listing for access control, supervised fire alarm disconnect, and Class 2 power limited outputs are all commercial spec items. Regulation matters on a card reader head end, which is fussier about ripple than a doorbell transformer.
