RCI RCI-DKPS-2A – Frequently Asked Questions

1) Will the RCI DKPS-2A power supply run 24VDC maglocks and 12VDC strikes on the same job?
Output voltage on the DKPS-2A is field selectable between 12VDC and 24VDC, so one unit is set to one voltage for everything hanging off it. All eight outputs come off that single selection. If an opening mixes 12V strikes with 24V mags, plan on a second supply set to the other voltage rather than trying to split this one.
2) How many doors can a 2 amp access control power supply like the RCI DKPS-2A actually support?
The DKPS-2A gives you 8 protected outputs but 2A of continuous current total, so the output count is about distribution, not extra capacity. Add up the holding current of every device you intend to hang on it and stay under 2A. Motorized latch retraction devices are the ones that catch people out, since inrush on those is heavy; the description lists MLR among supported loads, but a 2A supply will only carry a limited number of them. Maglocks and electric strikes at typical holding currents let you get more doors onto it.
3) Does the RCI DKPS-2A report a power failure back to the alarm panel or head end?
Four supervisory outputs are built in: AC power fail, battery fail, DC fail, and status, each on form C relay contacts. Form C gives you both a normally open and a normally closed leg, so you can wire them into a supervised zone on a fire or burglar panel or into an access control input either way it wants to see the trouble. That is the main reason to spec this over a basic transformer on a facility where someone has to know the door power dropped.
4) Does the RCI DKPS-2A come with a backup battery, or do I order that separately?
Standby batteries are a separate option on the DKPS-2A. The unit is built to accept them and monitors battery condition through its battery fail supervisory output, but plan on ordering the batteries as a line of their own. If you want a supply that ships as a battery backup package instead, the Adams Rite PS-1 is listed as a 1 amp 12/24VDC supply with battery backup, and the Command Access PS204/204B is a 2A 24VDC linear supply with battery backup.
5) What is the closest equivalent to the RCI DKPS-2A from another brand?
The straightest swap is the Von Duprin PS902 base power supply, listed as 2A 12/24VDC field selectable for access control, which matches the DKPS-2A on current and on the field-selectable dual voltage. The SDC 632 Series is also a 2 amp regulated and filtered supply with dual voltage selection. Where the DKPS-2A separates itself is the eight protected outputs and the four form C supervisory contacts built into the base unit.
6) Do I need a separate power supply for a motorized latch retraction exit device, or will the RCI DKPS-2A drive it?
The DKPS-2A lists motorized latch retraction devices among the loads its 2A continuous rating supports, so a small MLR application can run off it. On a bank of MLR devices, a supply built specifically for that duty is the better call, since MLR inrush is the hardest load in this category. ZenSupply carries the BEST RPSMLR2 Series, which is a power supply for motorized latch retraction exit devices, and the BEST PS161-6, a 120V input, 12/24V output supply at 6A capacity for delayed egress exit devices.
7) What should I use instead of the RCI DKPS-2A if 2 amps is not enough for the doors on the run?
Step up to a higher current supply. The SDC 634 Series is a 4 amp regulated and filtered low voltage supply with dual voltage selection, the Securitron AQL4 is a switching supply rated 12/24VDC at 4/3 amp, and the BEST PS161-6 is a 120V input, 12/24V output unit with 6A capacity. For a large 24 volt distribution the Altronix AL1024ULACMCB runs 24VDC at 10A with 8 PTC outputs from a 115VAC 60Hz input at 4.2A. The RCI DKPS-2A itself is a 2A unit, so the load total is the deciding number.
8) I need a power supply with battery backup - does the RCI DKPS-2A compare to units that include it?
The RCI DKPS-2A is battery backup ready with standby battery options for continuous power during AC failures, and it carries AC power fail, battery fail, DC fail and status supervisory outputs on form C relay contacts. Peers that state backup in their own description include the Adams Rite PS-1, a 1 amp 12/24 VDC regulated supply with battery backup, the Command Access PS204/204B linear supply at 2A 24VDC with battery backup, and the Detex 10-800 Series universal logic controller with a 120VAC/24VDC supply and battery backup. The PS204/204B matches the 2 amp figure but is 24VDC where the RCI unit is selectable 12 or 24.
9) Which items look like substitutes for the RCI DKPS-2A but are not power supplies for a door run?
Three to rule out. The ROFU 10305-LA/10306-LA is a tamper resistant power transfer hinge rated 1.5A at 42V in a plastic white finish - it moves power through the door edge, it does not make DC power. The Command Access CAT Field Tester is a portable 12-24VDC unit that runs off DeWalt, Makita and Milwaukee batteries, a bench and field test tool rather than a permanent supply. The Securitron BPSS is a boxed solar power supply, a different power source entirely. The RCI DKPS-2A converts 110/220 VAC into 12 or 24 VDC at 2 amps for fixed installation.
10) Can the RCI DKPS-2A be wired to 208 or 240 volt building power?
Input on the DKPS-2A is 110-220 VAC at 50 or 60Hz, so standard 120V branch circuits and 220V service both work. That 50/60Hz range also makes it usable on international installs without a separate model. It is a commercial-duty unit, not a plug-in wall transformer, so it wants a dedicated feed and a mounted location with clearance for wiring and ventilation.
11) What happens on the RCI DKPS-2A if an installer shorts a wire on one of the door runs?
Every one of the eight outputs carries electronic over-current protection, so a fault on one run trips that output rather than dropping the whole supply. Electronic protection resets itself once the fault clears, which is why it beats a fuse on a multi-door panel: no truck roll to swap a fuse after a pinched wire on one leaf.
12) Is the RCI DKPS-2A a fail-safe or fail-secure power supply?
Fail-safe versus fail-secure is field selectable on the DKPS-2A, set during configuration rather than fixed at the factory. That matters on egress and stair doors where the fire marshal wants locks to release on power loss, and on secure storage where they must not. Set it during commissioning and document the setting, because the next tech on site cannot tell from the outside which way it was configured.
13) Is the RCI DKPS-2A suitable for a single door, or is it overkill?
For one opening it is more supply than the job needs. Eight outputs and four supervisory relays are there to serve a multi-door panel, and paying for that on a single strike is wasted. For one door, look at the Command Access PS1 Series, a 24VDC linear supply with 1 amp output, the SDC 620 Series 1 amp regulated supply with dual voltage selection, or the Securitron AQD1 switching supply at 12/24 VDC 1 amp. Come back to the DKPS-2A when you are feeding several doors from one enclosure and need trouble reporting.
14) Is there a smaller power supply than the RCI DKPS-2A for a single door or two?
Yes. The Adams Rite PS-1 is a regulated 1 amp supply at 12/24 volts DC with battery backup, the Securitron AQD1 is a 12/24 VDC 1 amp switching supply, and the SDC 620 Series is a 1 amp regulated and filtered supply with dual voltage selection. The SDC 631 Series sits between at 1.5 amp with dual voltage selection. These keep the same 12 or 24 volt choice the RCI DKPS-2A offers but at lower current for a one or two device opening, where the DKPS-2A carries 2A across 8 protected outputs.
15) Is there a UL listed alternative to the RCI DKPS-2A for an access control kit?
The Aiphone AC-PS1250 is a UL listed 12V DC 5A supply made for AC Series access control kits, and the Command Access PS210 is a UL 6E/CSA listed linear supply at 1.5A 24VDC. The Altronix AL1024ULACMCB pairs a supply with an access power controller and 8 PTC outputs at 24VDC 10A. Note the AC-PS1250 is 12V only, so it does not cover a 24 volt device the field selectable RCI DKPS-2A would handle.
16) What is the alternative to the RCI DKPS-2A when the doors are delayed egress?
The BEST PS161-6 is built for delayed egress exit devices, taking 120V input to a 12/24V output at 6A capacity. The Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC supply and battery backup, so it adds control logic alongside power. The RCI DKPS-2A supplies 12 or 24 VDC at 2 amps with AC power fail, battery fail, DC fail and status supervisory outputs on form C contacts for remote monitoring, but the delayed egress sequencing lives in the exit device or a controller.
17) Is there a simpler plug-in option than the RCI DKPS-2A for a single 12 volt device?
The ROFU 9126T is a plug in mini power supply, 12 VDC at 1.5A with a built in time delay - no enclosure to mount or hardwire. The ROFU 9102-12D UL/9102-24D takes 10/120VAC 60Hz input and comes in 12D and 24D versions. The RCI DKPS-2A is the larger approach: a hardwired 110/220 VAC unit feeding 8 protected outputs at 2 amps for a multi-device system.
18) Can I use the RCI DKPS-2A in an apartment building or is it commercial only?
Classified as commercial equipment, the DKPS-2A is intended for hardwired building installs, and multi-tenant residential access systems are among the applications it is built for. Practically, that means it belongs in an electrical or IT room feeding the entry doors and amenity doors of a building, not plugged in behind a unit door. A property manager standardizing entry hardware across a portfolio gets the benefit of the supervisory contacts, which tell the office when door power has dropped at a building instead of waiting on a tenant call.
19) What is the difference between the RCI DKPS-2A and a power supply control module like the BEST ELR150?
The BEST ELR150 Series is a power supply control module for electronic access control - a control stage in the power path. The RCI DKPS-2A is the source itself, converting 110/220 VAC at 50 or 60Hz into 12 or 24 VDC with electronic over-current protection on all 8 outputs and dual supervisory outputs with form C relay contacts. The Locknetics LP Series is supplied with an enclosure. Confirm whether the job needs generation, distribution, or switching before choosing.
