Command Access PS1 – Frequently Asked Questions

1) Will the Command Access PS1 power supply run more than one electric lock?
No. The PS1 is a single-device supply, rated to run up to 1 lock, exit trim, or low-power motor/solenoid kit at 1A, 24VDC through one auto-resetting fused output. If you are powering several openings off one enclosure, step up to a multi-output board like the Altronix AL1024ULACMCB, which puts out 24VDC at 10A across 8 PTC outputs, or the RCI DKPS-2A with 8 outputs at 12/24VDC, 2A.
2) Is the PS1 a 24 volt only power supply, or can it be switched to 12 volts?
24VDC only. The PS1 has no voltage selection, so a 12V strike or maglock needs a different supply. Field-selectable 12/24VDC options include the Securitron AQD1 at 1A, the Von Duprin PS902 at 2A, and the SDC 620 Series with dual voltage selection at 1A. There is an output voltage trim pot on the PS1, but that is for fine adjustment of the 24V rail, not for dropping to 12V.
3) Can the PS1 power a motorized latch retraction exit device?
Only a low-power one. The PS1's linear design gives ample inrush and hold current for latch retraction in solenoid and motor-driven exit devices, and it is rated for up to 1 lock, exit trim, or low-power motor/solenoid kit at 1A. A full-draw motorized latch retraction device pulls more than that on inrush; for those, a purpose-built MLR supply such as the BEST RPSMLR2 Series is the right call. Check the current draw of the specific device before you commit.
4) How do I get fire alarm release on a maglock powered by a Command Access PS1?
Wire the fire alarm contacts in series with the PS1's input trigger. When the panel drops the contact, the trigger opens and the 24VDC output drops, releasing the lock. The input triggers are solid state, which protects the system relays from shorts, grounds, and surges coming off the alarm circuit. No separate relay module is needed for that function.
5) What is the closest 1 amp 24VDC equivalent to the Command Access PS1 from another brand?
The SDC 620 Series is the nearest match. It is a 1 amp regulated and filtered low voltage power supply with dual voltage selection, so it covers the same 1A capacity the PS1 delivers at 24VDC, with the SDC unit field selectable between voltages rather than fixed. The Securitron AQD1 is also a 1 amp unit, rated 12/24 VDC, but it is a switching supply where the PS1 uses a linear design that provides the inrush and hold current for latch retraction in solenoid and motor driven exit devices.
6) The PS1 only runs one lock. What power supply should I use for a bank of doors?
Step up in amperage. The SDC 632 Series is a 2 amp regulated and filtered low voltage supply and the SDC 634 Series is a 4 amp version, both with dual voltage selection. The Von Duprin PS902 is a 2A 12/24 VDC base power supply, field selectable. For a larger distribution job, the Altronix AL1024ULACMCB is a power supply and access power controller with 24VDC at 10A across 8 PTC outputs from a 115VAC 60Hz input, and the RCI DKPS-2A gives 8 outputs at 12/24VDC 2A. The Command Access PS1 is sized for up to 1 lock, exit trim, or low power motor and solenoid kit through its single output.
7) What looks like a substitute for the Command Access PS1 but is not one?
The ROFU 10305-LA/10306-LA is a tamper resistant power transfer hinge rated 1.5A at 42V in a white plastic finish. The 1.5A figure reads like a supply rating, but a transfer hinge carries power across the door edge, it does not generate it. The BEST ELR150 Series is a power supply control module, a control element rather than the source. The Command Access PS1 is the 24VDC 1A supply itself, taking 120VAC 60Hz input through a 2 amp fuse at 250VAC and feeding 1 solid state auto resetting fused output.
8) My devices are 12 volt, not 24. What should I order instead of the PS1?
The Command Access PS1 is a fixed 24VDC unit. For 12 volt loads, the Securitron AQS1210 is a switching supply at 12 VDC 10 Amp, and the Aiphone AC-PS1250 is a 12V DC 5A UL listed supply built for AC Series access control kits. If you want one unit that covers either voltage, the SDC 631 Series is a 1.5 amp regulated and filtered DC power controller with dual voltage selection, and the SDC 620 Series does the same at 1 amp.
9) Does the Command Access PS1 have battery backup for the lock?
The PS1 is a 120VAC, 60Hz input supply and does not include batteries. It does carry a battery output LED (orange), alongside red for AC power and green for DC output. If the job calls for a supply sold with backup, the Adams Rite PS-1 is a 1 amp 12/24VDC regulated supply with battery backup, and the Detex 10-800 Series pairs a 120VAC/24VDC supply and battery backup with a universal logic controller.
10) Linear versus switching power supply for an electric strike, which should I use?
Linear is the safer pick where the load slams the supply on every actuation. That is why the PS1 is built linear: it holds up ample inrush and hold current for latch retraction in solenoid and motor-driven exit devices, electric locks, electric strikes, and magnetic locks. Switching supplies run cooler and lighter for steady loads, and ZenSupply carries those too, such as the Securitron AQD1 at 12/24VDC 1 amp and the AQL4 at 12/24VDC 4/3 amp. For a continuous-duty maglock either works; for a solenoid or motor kit, go linear.
11) What protection does the Command Access PS1 have if an installer shorts the lock wiring?
Short a lead and the PS1 catches it. The single output is solid-state auto-resetting fused, so it recovers on its own once the fault is cleared instead of needing a fuse swap. On top of that it has over-voltage protection and intelligent short circuit detection, and the line side is fused at 2 amps at 250VAC. The green DC output LED tells you at a glance whether the output has folded back.
12) Is the Command Access PS1 UL listed for commercial access control work?
Yes, the PS1 is UL/CSA listed, and it is a commercial-rated device rather than a residential one. That matters on institutional and government jobs where the electrical inspector wants a listed supply feeding door hardware.
13) I need to power delayed egress hardware in a building. Is the PS1 enough?
Probably not. The PS1 is a 1 amp, 24VDC supply sized for a single lock or exit trim, and delayed egress panels typically drive both the locking device and their own control logic. The BEST PS161-6 is built for delayed egress exit devices with 120V input, 12/24V output and 6A of capacity. If you want a controller and supply in one can, the Detex 10-800 Series universal logic controller includes a 120VAC/24VDC supply.
14) Can I use a plug-in transformer style supply instead of the PS1?
The ROFU 9126T is a plug in mini power supply rated 12 VDC at 1.5A with time delay, which suits a small 12 volt opening but does not deliver 24VDC. The Command Access PS1 is a 24VDC unit with 120VAC 60Hz hard input, housed in an 11 inch W x 11 inch H x 4 inch D enclosure with 1/2 inch and 3/4 inch knockouts on all sides. If the device on the door is 24 volt, a 12 VDC plug in unit is not an alternative.
15) I need a supply for an opening with no AC run to it. What are my options next to the PS1?
The Securitron BPSS is a boxed solar power supply, which addresses an opening you cannot pull line voltage to. The Command Access PS1 requires standard 120VAC 60Hz input and mounts in an 11 inch W x 11 inch H x 4 inch D enclosure with 1/2 inch and 3/4 inch knockouts on all sides for conduit entry.
16) I am standardizing on one power supply across a building. Which unit should I compare against the PS1?
For a facility standard, the choice usually turns on how many openings feed off each supply. The Command Access PS1 is a commercial 24VDC unit with 1 solid state auto resetting fused output at 1A, sized for one lock or exit trim per box, so a building standard on the PS1 means one enclosure per opening. Multi output alternatives are the RCI DKPS-2A with 8 outputs at 12/24VDC 2A and the Altronix AL1024ULACMCB with 8 PTC outputs at 24VDC 10A from a 115VAC 60Hz input. The Von Duprin PS902 is a Grade 1 base power supply at 2A 12/24 VDC, field selectable.
17) Which power supply gives me fire alarm disconnect besides the Command Access PS1?
The Command Access PS1 handles this directly: fire alarm contacts can be wired in series with the input trigger to achieve fire alarm disconnect, and its solid state input triggers protect system relays from shorts, grounds, and surges. If your design calls for logic beyond a disconnect, the Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC power supply and battery backup, and the BEST ELR150 Series is a power supply control module for electronic access control.
18) Is the ROFU 9102 a direct swap for the Command Access PS1?
The ROFU 9102 is offered as the 9102-12D UL and 9102-24D, with 10/120VAC 60Hz input, so the 24D covers the 24 volt side while the 12D is the 12 volt version. The Command Access PS1 is a single 24VDC unit at 1A on 120VAC 60Hz input, with an output voltage trim pot for field adjustment, over voltage protection, and intelligent short circuit detection. Confirm you are pulling the 24D part and that the amperage suits the device before treating it as a swap.
19) How is the Command Access PS1 wired, and can I service it without pulling every conductor?
The PS1 lands on easy-to-remove euro connectors, so you can unplug the field wiring as a block to swap or bench-test the board without stripping and re-landing every conductor. Input is 120VAC, 60Hz; output is 24VDC at 1A. There is also an output voltage trim pot if a long wire run drops the voltage at the lock and you need to bring it back up.
20) How many models are in the Command Access PS1 Series, and which one do I order?
There is one: model PS1. No voltage, output, or enclosure options to specify, so the order is the model number alone. It comes configured as 120VAC in, 24VDC at 1 amp out.
