Command Access PS220 – Frequently Asked Questions

1) Will the PS220 power a Command Access MLRK1 Falcon 17 latch retraction kit?
Yes, and that is what the linear design is there for. Motorized latch retraction pulls a big inrush spike when the motor kicks and then needs steady hold current. The PS220/220B is a linear supply specifically called out as supplying ample inrush and hold current for the MLRK1 FAL17 retrofit kits. It also works with Command Access electric strikes and mag locks.
2) Can I tie the PS220B into the building fire alarm so the doors unlock on alarm?
Yes. The PS220/220B has a dry contact input for fire alarm integration, so an alarm relay drops power to the locks for emergency unlock. It also takes solid-state input triggers on the outputs for access control release, and carries over-voltage protection plus a voltage trim adjustment if your run length is dropping the voltage at the lock.
3) I need to power more than two doors off one power supply. Is the PS220 enough?
No. The PS220/220B tops out at two electrified locks on 2 amps at 24VDC with two fused outputs. For a bigger head end, the Altronix AL1024ULACMCB runs 24VDC at 10A across 8 PTC outputs with an access power controller built in, and the BEST PS161-6 gives 12/24V output at 6A capacity. Either one covers a multi-door bank the PS220 cannot.
4) What is the closest equivalent to the Command Access PS220 if I need a 2 amp 24VDC access control power supply from another brand?
Two peers land at the same 2 amp class. The SDC 632 Series is a 2 amp regulated and filtered low voltage power supply with dual voltage selection, and the Von Duprin PS902 is a base power supply rated 2A at 12/24 VDC field selectable for access control. The Command Access PS220/220B is specified at 2A @ 24VDC. The difference to weigh is design type: the PS220/220B is a linear supply, which the Command Access description ties to ample inrush and hold current for latch retraction hardware such as the MLRK1 Falcon 17 kits, while the SDC 632 and PS902 are described as regulated/filtered and field-selectable dual voltage respectively.
5) What should I use instead of the PS220 if I have more doors than 2 amps will carry?
Step up to a higher current supply. The SDC 634 Series is a 4 amp regulated and filtered low voltage power supply with dual voltage selection, and the Securitron AQL4 is a switching supply at 12/24VDC rated 4/3 amp. For a large multi-door bank, the Altronix AL1024ULACMCB is a power supply and access power controller with 115VAC 60Hz input at 4.2A, eight PTC outputs and 24VDC at 10A in a grey enclosure. The Command Access PS220/220B carries 2 amps at 24VDC with 2 PTC fused outputs, which sets the ceiling at roughly two electrified locks.
6) Is the ROFU 10305-LA a substitute for the PS220 power supply?
No. The ROFU 10305-LA/10306-LA is a tamper resistant power transfer hinge rated 1.5A at 42V in a plastic white finish. It carries current from the frame into the door leaf; it does not generate DC power. It would be installed alongside the Command Access PS220/220B, which supplies 2 amps at 24VDC from a wall-mounted enclosure to the lock. If you are looking for the supply itself, the ROFU 9102-12D UL/9102-24D is a power supply with 10/120VAC 60Hz input.
7) My exit devices are motorized latch retraction. Does the PS220 handle them or do I need a dedicated MLR supply?
The Command Access PS220/220B is a linear supply, and Command Access states the linear design guarantees ample inrush and hold current for smooth latch retraction with power-demanding hardware such as the MLRK1 Falcon 17 kits, at 2 amps and 24VDC across two PTC fused outputs. If your exit devices are another brand, the BEST RPSMLR2 Series is a power supply built for motorized latch retraction exit devices, and the BEST PS161-6 is a power supply for delayed egress exit devices with 120V input, 12/24V output and 6A capacity.
8) Does the PS220B come with batteries, or do I buy those separately?
The PS220B is battery backup ready, not battery included. The enclosure has the battery compartment, the automatic switchover, and an independent charging circuit; you supply the batteries. Once they are in, the supply carries the locks through a power outage and the orange LED tells you the battery is in play (red is AC present, green is DC output).
9) Linear or switching power supply for motorized latch retraction exit devices?
Go linear when the load is motor driven latch retraction. A linear supply like the Command Access PS220/220B holds up under the inrush spike a retraction motor draws and then sustains hold current, which is why it is specified for MLRK1 kits. Switching supplies are the other common option in this category, for example the Securitron AQL4 at 12/24VDC 4/3 amp or the Securitron AQD1 at 12/24 VDC 1 amp, and they are the lighter-duty choice for strikes and mag locks. If your device is a motorized latch retraction exit device, there are also purpose-built supplies for it such as the BEST RPSMLR2.
10) I only need to power one small electric strike, not two locks. Is there a smaller power supply than the PS220?
Yes. For a single low-draw device, the SDC 620 Series is a 1 amp regulated and filtered low voltage power supply with dual voltage selection, and the Securitron AQD1 is a switching supply at 12/24 VDC, 1 amp. The SDC 631 Series sits between them at 1.5 amps with dual voltage selection. The Command Access PS220/220B is built to run up to two electrified locks, exit trim, and a low-power motor/solenoid kit at 2 amps, so it is sized for a larger load than a lone strike.
11) I need more than two switched outputs off one supply. What is the alternative to the PS220?
The Command Access PS220/220B provides 2 PTC fused outputs with solid-state input triggers at 2 amps, 24VDC. If the job needs more distribution points, the RCI DKPS-2A is a power supply with 8 outputs at 12/24VDC and 2A, and the Altronix AL1024ULACMCB combines a power supply and access power controller with 8 PTC outputs at 24VDC and 10A. The BEST ELR150 Series is a power supply control module for electronic access control if you are adding control rather than replacing the supply.
12) Is a plug-in power supply like the ROFU 9126T an option in place of the PS220?
They serve different scopes. The ROFU 9126T is a plug in mini power supply at 12 VDC and 1.5A with time delay, which suits a single low-draw 12 volt device fed from a receptacle. The Command Access PS220/220B is an enclosure-mounted linear supply at 2 amps and 24VDC with a dry contact fire alarm input, over-voltage protection, voltage trim adjustment, and LED status indicators for AC, DC output, and battery. If the opening needs fire alarm release or a battery-backed enclosure, the mini supply will not cover it.
13) What differentiates the PS220 from a switching power supply of the same rating?
The design topology. The Command Access PS220/220B is described as a linear power supply, and Command Access ties that linear design to ample inrush and hold current for smooth latch retraction on power-demanding hardware. The Securitron AQD1, AQL4, and AQS1210 are switching power supplies at 12/24 VDC 1 amp, 12/24VDC 4/3 amp, and 12 VDC 10 amp respectively. If the load is a motorized retraction kit with a high momentary draw, the inrush behavior is the spec to confirm rather than the steady-state amperage alone.
14) For a gate or remote opening with no AC power run, is the PS220 the right choice?
No. The Command Access PS220/220B is a hardwired commercial linear supply delivering 2 amps at 24VDC and needs an AC feed to the enclosure. Where no AC run exists, the Securitron BPSS is a boxed solar power supply. Confirm the load draw of your hardware against whatever the solar unit will sustain before committing the opening to it.
15) How do I troubleshoot a Command Access PS220 that is not powering the lock?
Read the LEDs first. Red means AC is present at the supply, green means DC output is live, orange means the battery circuit is active on a PS220B. Green off with red on points at the PTC fused outputs, which trip on overload and reset once the fault clears rather than needing a fuse swap. If the lock is sluggish rather than dead, the voltage trim adjustment lets you bring output up to compensate for drop on a long wire run.
