RCI RCI-DKPS-6A – Frequently Asked Questions

1) How many doors can an RCI DKPS-6A power supply run?
Power budget decides it, not the output count. The DKPS-6A gives you 8 protected voltage outputs but 6 amps total across all of them, with a 2.0A ceiling on any single output. So add up the draw of every lock, strike, and mag you plan to hang off it and stay under 6A total. Eight 24VDC electric strikes pulling a few hundred milliamps each fit easily; a bank of maglocks or motorized latch retraction devices will eat the budget long before you use all eight outputs.
2) Is the RCI DKPS-6A 12 volt or 24 volt?
Both. The DKPS-6A is field selectable between 12 and 24VDC output, so you set it at install to match the devices on the doors. One caution: the selection sets the whole unit, so every device fed from it runs at the same voltage. If you have 12V strikes and 24V mags in the same job, you need two supplies or you standardize the hardware.
3) Can the DKPS-6A power both fail-safe and fail-secure locks?
Fail-safe versus fail-secure on the DKPS-6A is field selectable, so the installer configures the behavior on site rather than ordering a specific version. That matters for egress: fail-safe releases the lock when power drops, which is what you want on a stair door or an egress path tied to fire alarm, while fail-secure keeps the door locked through a power loss for asset protection. Set it to match what the life safety drawing calls for on that opening.
4) What happens if one device shorts out on an RCI DKPS-6A?
Each of the eight outputs has its own electronic over-current protection, so a short or an overdraw on one door trips that output instead of dropping the whole panel. The other doors keep running. Because the protection is electronic rather than a fuse, there is no fuse to replace after a fault, and the current rating on the unit is listed at 4A. That per-output isolation is the main reason to use a distributed supply like this instead of daisy-chaining doors off one unprotected feed.
5) Can I monitor an RCI DKPS-6A power supply from the head end?
Yes, and this is the feature that separates it from a basic transformer. Four supervisory outputs report AC power fail, battery fail, DC fail, and status, each on a form C relay contact. Form C gives you both normally open and normally closed, so you can wire the trouble condition into an access control panel input, a building management system, or a monitored alarm zone whichever way that input expects to see it. For a healthcare or campus job where somebody has to know a supply died before the doors start failing, that is the wiring you run.
6) Is a 6 amp access control power supply overkill, or should I use a smaller one?
Size it to the door count and the draw. The DKPS-6A at 6A across 8 outputs is a multi-door centralized supply. For one or two openings that is more capacity and more cost than the job needs, and a single-door unit fits better: the Securitron AQD1 is a 12/24 VDC 1 amp switching supply, the SDC 620 Series is a 1 amp dual voltage regulated unit, and the Von Duprin PS902 is a 2A 12/24 VDC field selectable base supply. Step up to the DKPS-6A when you are feeding a bank of doors from one closet and want per-output protection and trouble monitoring.
7) What is comparable to the RCI DKPS-6A for a multi-door access control panel?
Closest match on capacity is the BEST PS161-6, a 120V input, 12/24V output, 6A supply built for delayed egress exit devices. If you need more headroom on a 24V-only system, the Altronix AL1024ULACMCB is an access power controller with 8 PTC outputs at 24VDC and 10A, taking 115VAC 60Hz at 4.2A input. The DKPS-6A sits between them: 8 outputs like the Altronix, dual 12/24V selectable like the BEST, with electronic over-current protection rather than PTC devices on the outputs.
8) What is an equivalent 6 amp 12/24VDC power supply to the RCI DKPS-6A for a delayed egress exit device job?
The BEST PS161-6 is the closest match on the core electrical numbers. It runs a 120V input with 12/24V output at 6A capacity, the same dual-voltage selection and 6 amp rating the RCI DKPS-6A provides from a 120-240 VAC input. The BEST unit is specified for delayed egress exit devices, while the DKPS-6A distributes its 6 amps across 8 protected outputs with electronic over-current protection set at 4 amp and 2.0A maximum per output, plus form C supervisory relays for AC power fail, battery fail, DC fail and status. If the job is one or two delayed egress devices, the PS161-6 covers it; if the same 6 amps has to feed eight separate openings with individually protected runs, the DKPS-6A is the one built for that.
9) I need more than 8 amps at 24VDC for a bank of maglocks - what do I use instead of the RCI DKPS-6A?
Step up to the Altronix AL1024ULACMCB or the Securitron AQS1210. The Altronix AL1024ULACMCB is a power supply and access power controller rated 24VDC at 10A from a 115VAC 60Hz input drawing 4.2A, with 8 PTC outputs in a grey enclosure - same eight-output distribution count as the RCI DKPS-6A but at a higher DC rating and fixed at 24VDC. The Securitron AQS1210 is a switching supply rated 12 VDC at 10Amp, so it applies where the whole bank is 12 volt. The DKPS-6A tops out at 6 amps total across its 8 outputs, so once the connected load exceeds that, no amount of output count makes up the difference.
10) Is there a smaller power supply than the RCI DKPS-6A for a single electric strike?
For one opening, several dual-voltage units in the 1 to 4 amp range fit without the eight-output distribution. The SDC 620 Series is a 1 amp regulated and filtered low voltage supply with dual voltage selection, the SDC 632 Series is the same design at 2 amp, and the SDC 634 Series at 4 amp. The Securitron AQD1 is a switching supply at 12/24 VDC 1Amp, and the Von Duprin PS902 is a 2A 12/24 VDC base power supply, field selectable for access control - the same field-selectable voltage approach the RCI DKPS-6A uses. The DKPS-6A earns its place when one enclosure has to feed and individually protect up to eight devices with supervisory reporting; a single strike does not need that.
11) Does the RCI DKPS-6A have battery backup for power outages?
The DKPS-6A is built to take standby batteries, with multiple battery options available to keep doors powered through an AC failure, and it monitors that battery with a dedicated battery fail relay output. The batteries themselves are a separate order line, so budget for them on any job where the openings have to stay live during an outage.
12) Can I power motorized latch retraction exit devices from an RCI DKPS-6A?
Be careful here. Motorized latch retraction devices draw a heavy inrush when the motor pulls, and the DKPS-6A caps any single output at 2.0A with 6A across the whole unit. Check the inrush spec on the specific exit device before you commit. Where the device manufacturer calls for a dedicated MLR supply, use one: the BEST RPSMLR2 Series is a power supply built specifically for motorized latch retraction exit devices, and the BEST PS161-6 is intended for delayed egress exit devices. The DKPS-6A is better suited to strikes, mags, and electrified trim spread across multiple doors.
13) What do I need to set up on the DKPS-6A before it goes live?
Two configuration decisions get made in the field on a DKPS-6A, and both should be settled before you energize it: the output voltage, 12 or 24VDC, and the fail-safe versus fail-secure behavior. Beyond that it is confirming the 120-240 VAC feed and circuit capacity, mounting with clearance for wiring and ventilation, landing the supervisory relay outputs if the job monitors them, and then testing normal operation plus each monitoring output. Document the voltage and fail mode you set, because the next tech at that panel cannot tell by looking.
14) What is the difference between the RCI DKPS-6A and a power transfer hinge like the ROFU 10305-LA?
They do unrelated jobs and are not substitutes. 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 power across the gap from the frame into a moving door leaf. The RCI DKPS-6A is what generates that power in the first place, converting 120-240 VAC at 50/60Hz into 12 or 24VDC at 6 amps across 8 outputs. An electrified opening typically uses both: the DKPS-6A in the closet, the transfer hinge at the door, sized so the device load stays inside the hinge's 1.5A rating.
15) Which power supply should I use if I need battery backup rather than the RCI DKPS-6A?
The RCI DKPS-6A is standby battery ready with multiple standby battery options, and it reports on the battery through form C relay contacts for battery fail as well as AC power fail, DC fail and status. If a smaller unit with backup built into the description suits the opening, the Command Access PS204/204B is a linear supply at 2A 24VDC with battery backup, and the Adams Rite PS-1 is a regulated 1 amp 12/24 volt DC supply with battery backup. Those two are single-supply solutions at one or two amps; the DKPS-6A adds the 8-output distribution and the supervisory relay reporting that a monitored system wants.
16) Does the Command Access CAT Field Tester replace a permanently installed supply like the RCI DKPS-6A?
No. The Command Access CAT Field Tester is a portable 12-24VDC power supply that runs on DeWalt, Makita and Milwaukee batteries - it covers the same 12 to 24 volt range the RCI DKPS-6A outputs, which is why it gets mistaken for one, but it is a bench and jobsite tool for proving a device works before the permanent power is in. The DKPS-6A is the installed unit: 120-240 VAC in, 6 amps out across 8 protected outputs, with supervisory monitoring for AC power fail, battery fail, DC fail and status. Carry the tester, mount the DKPS-6A.
17) Is a plug-in supply like the ROFU 9126T an alternative to the RCI DKPS-6A?
Only for a single low-draw device. The ROFU 9126T is a plug in mini power supply rated 12 VDC at 1.5A with time delay, so it handles one strike on a wall outlet and brings its own timing function. The RCI DKPS-6A is a hardwired 120-240 VAC unit at 12 or 24VDC and 6 amps across 8 outputs, each with electronic over-current protection at 2.0A maximum, and it adds field-selectable fail-safe or fail-secure configuration plus four supervisory outputs. If the opening needs 24 volts, more than 1.5 amps, or more than one protected run, the 9126T does not reach it.
18) I need a UL Listed 12V supply for an intercom-based access control kit - is the RCI DKPS-6A the right pick?
For an Aiphone AC Series kit, the Aiphone AC-PS1250 is the matched part: 12V DC at 5A, UL Listed, and specified for AC Series access control kits. The RCI DKPS-6A is brand-agnostic distribution power at 12 or 24VDC, 6 amps across 8 outputs with per-output over-current protection and form C supervisory relays, which suits a mixed system of strikes, maglocks and controllers rather than a single manufacturer's kit. Where the kit calls out its own supply, follow the kit; where the panel and locks come from several makers, the DKPS-6A centralizes them.
19) What do I use instead of the RCI DKPS-6A when the door needs logic or sequencing, not just power?
The Detex 10-800 Series is a universal logic controller that includes a 120VAC/24VDC power supply and battery backup, so it combines the control decision with the power in one enclosure. The BEST ELR150 Series is a power supply control module for electronic access control. The RCI DKPS-6A is a power source and distribution unit: 12 or 24VDC at 6 amps over 8 outputs, field-selectable fail-safe or fail-secure, with four form C supervisory outputs for AC power fail, battery fail, DC fail and status. Its monitoring reports conditions to a head end; it does not sequence door operation on its own, so an opening with interlock or timing logic wants a controller alongside it or in place of it.
20) Is the RCI DKPS-6A rated for commercial use or is it a residential unit?
Commercial. The DKPS-6A is a commercial-grade access control power supply, and the applications it is built around are commercial building access control, multi-door electronic lock installations, healthcare and educational facility security, industrial entry control, government and municipal buildings, and retail loss prevention. It is a panel-mounted, hard-wired unit, not a plug-in transformer for a single residential door. For a small plug-in job, the ROFU 9126T is a plug in mini power supply at 12 VDC / 1.5A with time delay.
21) Is there a 24VDC-only supply to pair with the RCI DKPS-6A for a boosted or long wire run?
The Command Access PS210 is a UL 6E/CSA linear power supply with 1.5A at 24VDC and boost circuitry, which is the option when voltage drop on a long run is the concern. The Command Access PS1 Series is a 24VDC linear supply with 1 amp output for a straightforward single-device 24 volt load. The RCI DKPS-6A is selectable between 12 and 24VDC and delivers 6 amps across 8 outputs, so on a job where most openings sit close to the enclosure and one runs long, the DKPS-6A can cover the cluster while a boosted unit handles the outlier.
22) How does the Securitron AQL4 compare to the RCI DKPS-6A for a mid-size access control job?
The Securitron AQL4 is a switching power supply at 12/24VDC rated 4/3Amp, so it shares the DKPS-6A's dual voltage selection but delivers less current and derates when set to 24 volts. The RCI DKPS-6A holds 6 amps at either 12 or 24VDC and splits it across 8 outputs, each with electronic over-current protection at 2.0A maximum, and adds form C supervisory relays for AC power fail, battery fail, DC fail and status. On a four to six door job wired back to one closet, the output count and per-output protection on the DKPS-6A do the distribution the AQL4 leaves to a separate device.
23) What is a dual-voltage alternative to the RCI DKPS-6A in the 1.5 amp range?
The SDC 631 Series is a 1.5 amp regulated and filtered DC power controller with dual voltage selection, and the ROFU 9102-12D UL/9102-24D runs on a 10/120VAC 60Hz input with separate 12D and 24D versions. Both give the 12 or 24 volt choice the RCI DKPS-6A offers, at a fraction of its 6 amp capacity and without its 8 protected outputs and four supervisory relay outputs. Use the smaller units where a single device or a small pair is all the enclosure has to serve.
