Altronix ACM4CB – Frequently Asked Questions

1) My load is bigger than a couple of amps - what power supply should I be looking at for a bank of maglocks or strikes?
Size the supply to the total draw, not the door count. For heavier loads the BEST PS161-6 runs 120V in with 12/24V out at 6A capacity, the SDC 634 is a 4 amp regulated and filtered low voltage supply with dual voltage selection, and the Securitron AQS1210 is a 12 VDC 10 amp switching supply. The Securitron AQL4 sits between them at 12/24VDC, 4/3 amp.
2) Can I power a motorized latch retraction exit device or a delayed egress device off a general purpose access control supply?
Those two loads want purpose built power. Motorized latch retraction pulls a heavy inrush when it fires, and the BEST RPSMLR2 Series is built specifically for motorized latch retraction exit devices. Delayed egress has its own timing and power requirements, and the BEST PS161-6 is the supply listed for delayed egress exit devices, with 120V input and 12/24V output at 6A. Pairing either device with a plain low amp supply is the usual reason a device chatters or fails to retract.
3) Does an Altronix ACM4CB give me battery backup for access control doors?
The ACM4CB is an access power controller that distributes a 12/24VAC/DC input across four PTC outputs. Where the openings must stay powered through a utility outage, look to units that carry backup in their build: the Adams Rite PS-1 is a regulated 1 amp 12/24 volt DC supply with battery backup, the Command Access PS204/204B is a linear supply with 2A at 24VDC and battery backup, and the Detex 10-800 Series universal logic controller pairs a 120VAC/24VDC supply with battery backup. A common arrangement is a backed-up source upstream with the ACM4CB handling output distribution downstream.
4) What is the closest equivalent to an Altronix ACM4CB access power controller when a multi-output board is needed?
The Altronix ACM4CB takes a 12/24VAC/DC input and distributes it across four PTC-protected outputs, so the nearest peer is a board that splits one source into several protected door outputs. The RCI DKPS-2A provides eight outputs at 12/24VDC and 2A for access control systems. The difference is where the power comes from: the ACM4CB is fed from an existing 12/24VAC/DC source, while the DKPS-2A is described as a power supply in its own right. If the panel already has a transformer or supply feeding it, the ACM4CB adds the output distribution; if the run needs both, the DKPS-2A covers supply and outputs in one unit.
5) What should I use instead of an Altronix ACM4CB if there is no low voltage source at the panel and I am starting from line voltage?
The Altronix ACM4CB is fed at 12/24VAC/DC, so it needs an upstream source. When the only power at the location is line voltage, a unit that converts it directly is the fit. The BEST PS161-6 takes a 120V input and delivers 12/24V output at 6A capacity, and the ROFU 9102-12D UL/9102-24D operates from a 10/120VAC, 60Hz input. Either handles the line-voltage-to-low-voltage step that the ACM4CB assumes has already been done.
6) Will an Altronix ACM4CB run motorized latch retraction exit devices?
Motorized latch retraction draws a heavy inrush at the moment the motor pulls the latch, and it is normally handled by a supply built for that duty rather than by a general output board. The BEST RPSMLR2 Series is a power supply specifically for motorized latch retraction exit devices, and the BEST PS161-6 is specified for delayed egress exit devices with a 6A capacity from a 120V input. The Altronix ACM4CB is an access power controller distributing a 12/24VAC/DC input across four PTC outputs, which suits maglocks, strikes and similar continuous-draw hardware.
7) What else does ZenSupply carry for access control power besides the Altronix ACM4CB?
Plenty, and the right one depends on how many devices you are feeding. If you need distributed outputs like the ACM4CB gives you, the RCI DKPS-2A runs eight outputs at 12/24VDC, 2A. For a single door or a small run, the Securitron AQD1 is a 12/24 VDC 1 amp switching supply and the Command Access PS1 is a 24VDC linear supply with 1 amp out. Von Duprin's PS902 is a 2A 12/24 VDC field selectable base supply, which is the common starting point on Von Duprin electrified openings.
8) What is the difference between a power supply and an access power controller for a card access system?
A power supply just makes DC. An access power controller takes that DC and splits it into individually protected outputs you can switch from the access control panel, fire alarm relay or a request to exit, so each door drops independently instead of the whole board going dark. The Altronix ACM4CB is the controller side of that split. Products like the Command Access PS1 or the Securitron AQD1 are supplies only, and the SDC 631 is a 1.5 amp regulated and filtered DC power controller with dual voltage selection if you want the two functions in one smaller box.
9) Do I need to run a dedicated 120V circuit for an Altronix access power controller?
The ACM4CB is a 120V product, so it needs line voltage at the enclosure. On a typical install the electrician brings a 120VAC branch circuit to the backbox location and the integrator lands everything low voltage from there. If you cannot get line voltage to that wall, a plug in unit like the ROFU 9126T mini supply at 12 VDC 1.5A with time delay is the kind of thing used for a single opening instead.
10) How do I get power across the door to an electrified lock once the supply is in?
You still need a transfer at the hinge edge. The supply or controller feeds the enclosure, but the run from frame to door leaf goes through a power transfer device such as the ROFU 10305-LA/10306-LA tamper resistant power transfer hinge, rated 1.5A at 42V. Check that rating against the draw of whatever lock or exit device trim you are feeding before you commit to it.
11) If I only have one door to power, is there a simpler option than an Altronix ACM4CB?
The ACM4CB is built around four PTC outputs, which is more distribution than a single opening uses. For one door, a single-output supply covers it: the Command Access PS1 is a 24VDC linear power supply with 1 amp output, the SDC 620 Series is a 1 amp regulated and filtered low voltage supply with dual voltage selection, and the Securitron AQD1 is a 12/24 VDC 1 amp switching supply. The tradeoff is expansion - a single-output unit powers the one opening, while the ACM4CB's four outputs let one source feed several doors with each leg individually protected.
12) I need more current than a small controller provides for a bank of maglocks - what are the higher output choices?
When several maglocks hold continuously off one source, the amperage of the supply feeding the distribution decides the design. The Securitron AQS1210 is a 12 VDC 10 amp switching power supply, the BEST PS161-6 offers 6A capacity with a 120V input and 12/24V output, the SDC 634 Series is a 4 amp regulated and filtered low voltage supply with dual voltage selection, and the Securitron AQL4 is a 12/24VDC switching supply at 4/3 amp. Any of these can serve as the 12/24VAC/DC source that an Altronix ACM4CB then splits across its four PTC outputs.
13) How does an Altronix ACM4CB compare with a field selectable base power supply for an access control system?
The Von Duprin PS902 is a base power supply rated 2A at 12/24 VDC, field selectable for access control, and it carries a Grade 1 designation. The Altronix ACM4CB is an access power controller taking a 12/24VAC/DC input and providing four PTC outputs. The PS902 establishes the source and its voltage is set in the field; the ACM4CB accepts either 12 or 24, AC or DC, at its input and divides it into four separately protected legs. On a multi-door frame where one supply feeds several openings, the two describe different halves of the same power path rather than competing choices.
14) Is the Altronix ACM4CB a commercial grade access control power product or something for a house?
Commercial. The ACM4CB is classed as commercial access power controller equipment with power supplies, which is the gear that goes in a security integrator's enclosure feeding strikes, maglocks and readers in an office, school or multi family building, not a residential plug in adapter.
