Altronix AL400ULACMCB – Frequently Asked Questions

1) How many doors can the Altronix AL400ULACMCB run at once?
Eight. The AL400ULACMCB converts a 115VAC 60Hz input into eight independently controlled 12/24VDC fail-safe/fail-secure outputs, sharing a total of 4A at 12VDC or 3A at 24VDC. So the door count is really a current budget question: add up the holding or release current of every lock, strike and mag you plan to hang on it and stay under 4A at 12V (3A at 24V). Eight low-draw electric strikes fit comfortably; eight mag locks will not.
2) Does the Altronix AL400ULACMCB do both fail-safe and fail-secure locks on the same board?
Yes, and that is the main reason to pick this board over a plain power supply. Each of the eight outputs is independently controlled and can be set fail-safe or fail-secure, so a mag lock or fail-safe strike that has to drop on alarm can sit on the same panel as a fail-secure strike that stays locked when power is lost. Mixed openings on one enclosure, one 115VAC feed.
3) Is the AL400ULACMCB 12 volt or 24 volt?
Either, selectable: 4A at 12VDC or 3A at 24VDC. Note that the choice is made for the board as a whole, not per output, so a job mixing 12V strikes and 24V mag locks needs two supplies or needs the hardware standardized to one voltage. Input is 115VAC 60Hz at 3.5A.
4) What comes in the box with the Altronix AL400ULACMCB, and what do I still have to buy?
The AL400ULACMCB ships as a complete assembly in a grey enclosure with the charger and eight PTC-protected Class 2 relay outputs on board. Batteries are not part of that list, so if you want standby on power loss you order the sealed lead-acid batteries separately, along with your own conduit fittings and the access control panel or reader inputs that trigger the relays.
5) Will the Altronix AL400ULACMCB run a motorized latch retraction exit device?
Motorized latch retraction has its own supply because of the inrush the motor draws when the latch pulls back. The BEST RPSMLR2 Series is the power supply built for motorized latch retraction exit devices, and it is the right pick for that hardware. The AL400ULACMCB is an access power controller with eight PTC Class 2 relay outputs sized at 4A at 12VDC or 3A at 24VDC, intended for fail-safe/fail-secure door outputs rather than MLR duty. Delayed egress exit devices are a separate case again - the BEST PS161-6 is the supply specified for those.
6) What is the closest equivalent to the Altronix AL400ULACMCB from another brand for a 12/24VDC access control power supply?
The Securitron AQL4 switching power supply is the closest match on output: it delivers 12/24VDC at 4/3 amps, the same 4A at 12VDC or 3A at 24VDC the AL400ULACMCB supplies. The difference is in what each one does with that power. The AL400ULACMCB converts its 115VAC 60Hz input into eight independently controlled 12/24VDC fail-safe/fail-secure outputs, so it is both the supply and the access power controller in one grey enclosure. The AQL4 is a switching supply without the eight-output access control section, so door control relays and fire alarm interface would be handled by a separate board.
7) What does PTC protected mean on the AL400ULACMCB outputs, and do I need to stock spare fuses?
No spare fuses needed. The eight outputs are PTC protected, meaning each one uses a resettable polymer device instead of a glass fuse. Short a lock lead in the field and that output shuts down on its own, then restores once the fault is cleared and the circuit cools. For an MRO or property maintenance crew that is one less consumable on the truck, and one less midnight call to swap a fuse on a door that got slammed.
8) What is the difference between an access power controller like the AL400ULACMCB and a plain power supply?
A plain power supply just makes DC. An access power controller adds the switching: the AL400ULACMCB has eight independently controlled outputs, each settable fail-safe or fail-secure, so the access system's relay outputs release individual doors through the panel instead of through eight separate relays you wire yourself. If all you need is clean DC to one or two devices, something like the Securitron AQD1 12/24VDC 1 Amp switching supply or the SDC 620 Series 1 Amp regulated supply does the job with far less panel. Once you are controlling multiple doors from a head end, the controller earns its place.
9) What else can I use if I need eight door outputs but less current than the Altronix AL400ULACMCB?
The RCI DKPS-2A is the closest peer on output count: eight outputs at 12/24VDC, 2A, for access control systems. The AL400ULACMCB gives you more headroom at 4A @ 12VDC or 3A @ 24VDC across its eight outputs, which matters when several of those doors are mag locks or continuous-draw strikes. Same architecture, different current budget.
10) Can the AL400ULACMCB hold my doors up during a power outage?
The board includes the charger, so it is built to run standby batteries and keep the access outputs alive when the 115VAC feed drops. You supply the batteries. Worth thinking through per opening: fail-secure strikes stay locked without power regardless, while fail-safe hardware and mag locks release the moment the DC goes away, which is exactly why battery standby gets specified on those openings. If you want a supply that ships with backup as part of the package, the Adams Rite PS-1 is a 1 amp 12/24VDC regulated supply with battery backup.
11) I only need to power one electric strike - is there a simpler option than the Altronix AL400ULACMCB?
For a single opening, a one-amp supply covers it without the eight-output controller section. The Securitron AQD1 is a switching power supply at 12/24 VDC 1 Amp, the Command Access PS1 is a 24VDC linear supply with 1 amp output, and the SDC 620 Series is a 1 amp regulated and filtered low voltage supply with dual voltage selection. The AL400ULACMCB is built for the multi-door case instead - its 115VAC 60Hz input feeds eight independently controlled fail-safe/fail-secure outputs, which is capacity a single strike does not use.
12) What looks like an alternative to the Altronix AL400ULACMCB but will not do the same job?
A few items in the same family are not swaps for it. The ROFU 9126T is a plug-in mini power supply, 12 VDC at 1.5A with time delay - a plug-in module, not an enclosed multi-door controller. The Command Access CAT Field Tester is a portable 12-24VDC supply that runs off DeWalt, Makita and Milwaukee batteries, meant for bench and field testing rather than permanent installation. The Securitron BPSS is a boxed solar power supply, which addresses openings with no AC feed. The AL400ULACMCB is a fixed-install unit taking a 115VAC 60Hz input and feeding eight fail-safe/fail-secure door outputs from a grey enclosure.
13) Does the Altronix AL400ULACMCB include battery backup, or do I need a different unit for standby power?
The AL400ULACMCB ships with a charger in the enclosure, which is the piece that maintains standby batteries. If you are comparing against peers that state backup, the Adams Rite PS-1 is a regulated 1 amp 12/24 volt DC supply with battery backup, and the Command Access PS204/204B is a linear supply at 2A at 24VDC with battery backup. Both are single-circuit supplies at lower current; the Altronix unit pairs its charger with eight independently controlled 12/24VDC outputs at 4A at 12VDC or 3A at 24VDC, so standby power and multi-door switching come from one box.
14) How does the Altronix AL400ULACMCB compare to SDC power supplies for a mid-size access control job?
SDC's dual voltage line steps by amperage: the SDC 632 Series is a 2 amp regulated and filtered low voltage supply with dual voltage selection, and the SDC 634 Series is the 4 amp version of the same. The 634 matches the AL400ULACMCB's 4A at 12VDC. Where they part company is the output section - the Altronix unit delivers eight PTC Class 2 relay outputs that are independently controlled fail-safe or fail-secure, so each door can be switched separately; the SDC units are regulated and filtered supplies, with switching handled elsewhere in the system.
15) What should I specify instead of the Altronix AL400ULACMCB if the opening needs egress logic and timing, not just power?
When the sequence itself has to be controlled - delayed egress timing, interlocks, alarm logic - the Detex 10-800 Series universal logic controller combines that logic with a 120VAC/24VDC power supply and battery backup, and the BEST ELR150 Series is a power supply control module for electronic access control. The AL400ULACMCB handles the power side: a 115VAC 60Hz input feeding eight independently controlled fail-safe/fail-secure outputs rated 4A at 12VDC or 3A at 24VDC, with the access decision coming from the head-end system.
16) Can I use the Altronix AL400ULACMCB in a house, or is it commercial only?
It is built and specified as commercial equipment. A grey steel enclosure, a 115VAC 60Hz hardwired input at 3.5A, and eight relay-controlled access outputs all point at a commercial access control installation, not a residential doorbell or single-door retrofit. A single-door home job is far better served by a small plug-in supply.
17) Do I need a dedicated circuit for the Altronix AL400ULACMCB, and what is the AC side?
The AC side is 115VAC 60Hz at 3.5A, a standard 120V feed, so it is hardwired to line voltage rather than plugged into a wall wart. Plan on an electrician or a licensed low-voltage tech bringing that feed to the enclosure. If a plug-in supply suits the job better, the ROFU 9126T is a plug-in mini supply at 12VDC 1.5A with time delay.
18) Can I use the AL400ULACMCB for cameras or a fire alarm instead of door locks?
Altronix power supplies get used across CCTV, fire alarm and POIP as well as general access control. With the AL400ULACMCB the practical limit is the current budget, 4A at 12VDC or 3A at 24VDC shared across the eight outputs, so a handful of 12V cameras is realistic while a large camera count is not. Fire alarm work carries its own code and listing requirements for the facility, so that decision belongs with the AHJ and the alarm contractor, not the power supply spec alone.
