Altronix AL400ULACM – Frequently Asked Questions

1) Will the Altronix AL400ULACM run eight mag locks off one board, or do I need a separate supply for each door?
Eight doors run off the one board. The AL400ULACM gives you eight independently controlled outputs, each triggered on its own by an access control panel, card reader, keypad, push button or PIR. The limit is current, not channels: 4A total at 12VDC, or 3A total at 24VDC, shared across all eight. Add up the holding current of your mag locks or strikes and stay under that number. Fuses on the outputs are rated 3.5A and the board main fuse is 10A.
2) Does the AL400ULACM drop the mag locks on a fire alarm?
Yes, and you can pick which doors it drops. The fire alarm disconnect is individually selectable for any or all of the eight outputs, and it can be set latching or non-latching. The FACP interface takes either a normally open or normally closed dry contact, or a polarity reversal input from an FACP signaling circuit, so it wires to most panels as they sit. A green LED shows when the FACP disconnect has tripped, and an alarm relay output signals that the FACP input fired.
3) Can one Altronix power controller handle both fail-safe mag locks and fail-secure strikes on the same job?
It can, in any mix. Each of the eight outputs can be set fail-safe or fail-secure, so mag locks that release on power loss and electric strikes that stay locked can share the same board. Outputs can also be configured as form C 5A relay outputs instead of powered outputs, or any combination of powered and relay across the eight. That is what makes this a controller rather than just a supply, and it covers mag locks, electric strikes and magnetic door holders off one enclosure.
4) Is the AL400ULACM 12 volt or 24 volt?
Either, selected on the board: 12VDC at 4A, or 24VDC at 3A. It runs the whole board at one voltage, so a job mixing 12V strikes and 24V mag locks needs a second supply for the odd voltage rather than a per-output setting. Input is 115VAC 60Hz rated at 3.5A, and outputs are filtered, electronically regulated and Class 2 rated power limited.
5) What do I have to order with an Altronix AL400ULACM to finish the install?
The AL400ULACM ships with the grey enclosure, the built-in battery charger and the eight fused relay outputs, so the controller side is complete out of the box. Batteries are not included and are sold separately; it takes sealed lead acid or gel type. If you want the lock power isolated from board power you also need a second external supply, since only the single common input is factory installed.
6) What happens to the doors when the power goes out on an AL400ULACM?
With a standby battery fitted, the unit switches over automatically when AC fails, with zero voltage drop through the transition, so locks and readers do not blink. It also supervises the AC failure on form C contacts, with the notification trigger selectable at 30 seconds (factory setting) or 6 hours, plus separate form C supervision for low battery and battery presence. Without a battery installed, the outputs simply drop and fail-safe locks release.
7) What do I use instead of the AL400ULACM for motorized latch retraction exit devices?
Motorized latch retraction draws a high inrush at the moment of retraction and is normally fed by a supply built for it. The BEST RPSMLR2 Series is a power supply for motorized latch retraction exit devices, and the BEST PS161-6 is a 120V input, 12/24V output supply with 6A capacity for delayed egress exit devices. The Altronix AL400ULACM is aimed at routing power to mag locks, electric strikes and magnetic door holders from access control triggers.
8) What is the closest equivalent to the Altronix AL400ULACM if I need eight independently controlled 12/24VDC outputs from one board?
The RCI DKPS-2A is the nearest match on output count: it is a power supply with 8 outputs at 12/24VDC rated 2A for access control systems. The Altronix AL400ULACM also gives eight independently controlled outputs, but its supply current is 4A at 12VDC or 3A at 24VDC, so the total load budget across those eight doors is the deciding difference. Add up the holding current of every lock and strike you intend to run before choosing between them.
9) I need more than 4 amps of lock power. What should I use instead of the AL400ULACM?
The Altronix AL400ULACM supplies 4A at 12VDC or 3A at 24VDC. Where the door count or lock draw exceeds that, the BEST PS161-6 is a 120V input, 12/24V output supply with 6A capacity, and the Securitron AQS1210 is a switching supply at 12VDC 10 Amp. Note the trade: those are supplies, while the AL400ULACM includes eight fused relay outputs and a charger in the enclosure, so with a larger supply you may still need separate output control for each door.
10) How does the Securitron AQL4 compare to the Altronix AL400ULACM?
They land on the same current figures from different directions. The Securitron AQL4 is a switching power supply rated 12/24VDC at 4/3 Amp, matching the AL400ULACM's 4A at 12VDC or 3A at 24VDC. The difference is what happens downstream: the AL400ULACM's eight outputs are independently controlled and switch fail-safe and/or fail-secure from access control triggers, and it carries a built-in battery charger with automatic switchover on AC failure.
11) Can I power the locks from a separate supply and keep the controller on its own circuit?
Yes. Two wiring arrangements are supported: one common power input feeding both the ACM8/ACM8CB board and the lock power, which is how it comes factory installed, or two isolated inputs, one for the board and one for lock and accessory power, using an external supply. On the isolated arrangement the available current is whatever the connected supply provides, up to a 10A total maximum.
12) What kind of trigger input does the Altronix ACM8 board accept from my access control panel?
Each of the eight channels takes either an open collector sink or a normally open dry contact, and you can mix the two across the board in any combination. That covers most panel relay outputs and most reader or keypad boards without an interface module. Red LEDs on the board show which outputs are triggered, which makes commissioning eight doors quicker than metering each one.
13) How do I size a power supply against a multi-door access control controller like the AL400ULACM?
Single-door and small jobs do not need the eight-channel controller. ZenSupply carries plenty of straight supplies for that: the Securitron AQD1 at 12/24VDC 1 amp, the SDC 632 Series at 2 amps, or the Von Duprin PS902 base supply at 2A 12/24VDC field selectable. Where the AL400ULACM earns its place is when eight openings each need their own trigger, their own fail-safe or fail-secure behaviour, and a shared fire alarm disconnect. If you need more raw current on one voltage rather than channel control, the Securitron AQS1210 is 12VDC at 10 amps.
14) What else does ZenSupply sell that controls eight doors like the AL400ULACM?
The closest peer on channel count is the RCI DKPS-2A, which also has 8 outputs at 12/24VDC, rated at 2A. The Altronix carries more current, 4A at 12VDC or 3A at 24VDC. For a bigger single-voltage budget the BEST PS161-6 is a 120V input, 12/24V output supply with 6A capacity, though it is aimed at delayed egress exit devices. The Detex 10-800 Series is a different animal again: a universal logic controller with a 120VAC/24VDC supply and battery backup, for jobs where the logic matters more than the door count.
15) Are there spare unswitched outputs on the AL400ULACM for readers and REX devices?
There are eight auxiliary power outputs that stay on, separate from the eight switched lock outputs. Those are where card readers, REX sensors and PIRs go, since they should not drop when a door output is cycled. Everything still comes out of the same total budget of 4A at 12VDC or 3A at 24VDC, and the outputs are short circuit and thermal overload protected.
16) What is the difference between the Altronix AL400ULACM and the Detex 10-800 controller?
The Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC power supply and battery backup, so its logic is aimed at a single controlled opening. The Altronix AL400ULACM is a multi-output access power controller: one 115VAC input feeding eight independently controlled outputs that can run fail-safe, fail-secure, or a mix, each with selectable fire alarm disconnect. Both carry standby battery capability, the AL400ULACM through a built-in charger for sealed lead acid or gel batteries, sold separately.
17) Is the ROFU 10305-LA a substitute for an Altronix AL400ULACM?
No. The ROFU 10305-LA/10306-LA is a power transfer hinge rated 1.5A at 42V in a tamper resistant plastic white finish. It carries wiring from the frame into the door leaf; it does not generate or control power. The Altronix AL400ULACM converts a 115VAC 60Hz input into eight controlled DC outputs. On an electrified opening you would commonly need both: the controller at the source and a transfer device at the hinge.
18) Do I need the AL400ULACM if my access control panel already switches the locks?
If the panel switches each lock itself, the multi-output control on the Altronix AL400ULACM is redundant and a plain supply may serve. The Von Duprin PS902 is a base power supply at 2A, 12/24VDC field selectable for access control, and the SDC 632 Series is a 2 amp regulated and filtered supply with dual voltage selection. Where the panel provides only dry contact or open collector signals, the AL400ULACM's eight trigger inputs accept those and do the switching, including individually selectable fire alarm disconnect on any or all eight outputs.
19) Can a plug-in supply like the ROFU 9126T replace the AL400ULACM?
Only on a very small job. The ROFU 9126T is a plug in mini power supply at 12 VDC and 1.5A with time delay, and the ROFU 9102-12D UL/9102-24D runs on 10/120VAC 60Hz input. Neither addresses what the Altronix AL400ULACM is specified for: eight independently controlled outputs, AC fail and low battery supervision on form C contacts, and fire alarm disconnect that is individually selectable per output. If the job requires FACP interface for emergency egress, a plug-in mini supply will not satisfy it.
20) I need a 24VDC supply with battery backup for one or two openings. What are the alternatives to the AL400ULACM?
The Command Access PS204/204B is a linear power supply with 2A at 24VDC and battery backup, the Adams Rite PS-1 is a regulated power supply at 1 amp, 12/24 volts DC with battery backup, and the Command Access PS210 is a UL 6E/CSA linear supply with 1.5A at 24VDC output and boost circuitry. The Altronix AL400ULACM also supports standby battery with zero voltage drop at switchover, but it is sized for 3A at 24VDC spread over eight controlled outputs, which is more board than a one or two door opening calls for.
21) Can I mount an AL400ULACM in an unconditioned electrical room or a mechanical space?
Operating range is 0 to 49 degrees C (32 to 120 degrees F), with storage from -20 to 70 degrees C (-4 to 158 degrees F) and relative humidity of 85 percent plus or minus 5 percent. So an unheated space that drops below freezing is out. Heat load in a closed closet is modest: roughly 25 BTU/hr at 12VDC and 37 BTU/hr at 24VDC. It is a commercial-rated unit and comes in its own grey enclosure.
22) Does the AL400ULACM need a 120 volt circuit or does it plug in?
It is hardwired to 115VAC 60Hz, rated at 3.5A on the input, listed at 120V. That means an electrician-run branch circuit into the enclosure, not a receptacle plug-in. If you want something that plugs into an outlet for a single opening, the ROFU 9126T is a plug-in mini power supply, 12VDC at 1.5A with a time delay.
23) Is the Aiphone AC-PS1250 interchangeable with the Altronix AL400ULACM?
They serve different roles. The Aiphone AC-PS1250 is a power supply for AC Series access control kits, 12V DC 5A, UL listed, so it is matched to that kit's equipment. The Altronix AL400ULACM is brand-independent in the sense that its eight outputs are driven by open collector or normally open dry trigger inputs from an access control system, card reader, keypad, push button or PIR, and each output can be set fail-safe or fail-secure. If the job is an Aiphone kit, use the kit's supply; if the job is a mixed bank of mag locks and strikes, the AL400ULACM is the fit.
24) What is the difference between the Altronix AL400ULACM and the BEST ELR150 control module?
The BEST ELR150 Series is a power supply control module for electronic access control, meaning it adds control to a power source. The Altronix AL400ULACM combines both in one grey enclosure: a 115VAC 60Hz input rated at 3.5A feeding a built-in filtered and electronically regulated supply, plus eight relay outputs with fuses rated at 3.5A and a 10A board main fuse. Choose the module route when a supply is already installed and only switching is missing; choose the AL400ULACM when the opening bank needs supply, control and charger together.
