The R20470 SAM RF Emergency Lock Power Supply is for Dormakaba InSync locks only. It is not a general purpose access control power supply, so don't spec it to power a maglock, an electric strike, or another brand's electrified device. For those openings you want a general purpose unit like the Von Duprin PS902 or an SDC 632.

The Dormakaba R20470 SAM RF Emergency Lock Power Supply is built for InSync locks, so it is not the unit for a delayed egress exit device. For that application the BEST PS161-6 power supply is designed for delayed egress exit devices with 120V input, 12/24V output and 6A capacity. If the device is a motorized latch retraction exit device instead, the BEST RPSMLR2 series power supply is the one built for motorized latch retraction.

No. The Dormakaba R20470 is a SAM RF Emergency Lock Power Supply (ELPS) intended for InSync locks only, so it is matched to that lock platform rather than being a generic DC source. General access control supplies such as the Von Duprin PS902 base power supply, field selectable 2A at 12/24 VDC, or the Securitron AQD1 switching power supply at 12/24 VDC 1 Amp will power strikes, mags and electrified trim, but they are not the dedicated ELPS unit for a Dormakaba InSync opening. If the drawing calls for the R20470 on InSync hardware, order the R20470 and use the generic supplies for the rest of the system.

It is the emergency lock power supply (ELPS) piece of the SAM RF system, a power supply component within the access control chain rather than a lock or a reader. Because it is dedicated to Dormakaba InSync hardware, it is ordered as part of that system, not as a standalone replacement for a boxed access control supply.

They address the requirement differently. The Dormakaba R20470 is the SAM RF Emergency Lock Power Supply (ELPS) specified with InSync locks. If what you need is a standby battery on a conventional access control circuit, 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 universal logic controller includes a 120VAC/24VDC power supply with battery backup. Those are standby-power products for standard electrified hardware, not replacements for the InSync ELPS.

The Dormakaba R20470 is a SAM RF Emergency Lock Power Supply for InSync locks, a single dedicated unit rather than a multi-output distribution panel. For multi-door distribution, the Altronix AL1024ULACMCB combines 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, and the RCI DKPS-2A offers eight outputs at 12/24VDC and 2A for access control systems. On an InSync opening you would still specify the R20470 for the lock itself.

Two to watch. 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 door edge and generates none, so it complements a supply rather than replacing one. The Command Access CAT Field Tester is a portable 12-24VDC power supply that runs on DeWalt, Makita and Milwaukee batteries and is a bench and field test tool, not a permanently installed door supply. The Dormakaba R20470 is the SAM RF Emergency Lock Power Supply specified with InSync locks.

One model only, R20470. There are no voltage, output, or enclosure options to pick, so the order is simply the part number.

The Dormakaba R20470 is the SAM RF Emergency Lock Power Supply tied to InSync locks. For a single small device on a conventional circuit, smaller stand-alone units include the ROFU 9126T plug-in mini power supply at 12 VDC and 1.5A with time delay, the Command Access PS1 24VDC linear supply with 1 amp output, and the SDC 620 series 1 amp regulated and filtered low voltage supply with dual voltage selection. These are sized for one device and do not carry the InSync ELPS role.

The Dormakaba R20470 SAM RF Emergency Lock Power Supply is matched to InSync locks. Where the job is a packaged access control kit, the Aiphone AC-PS1250 is a UL listed 12V DC 5A power supply for AC Series access control kits, and the Command Access PS210 is a UL 6E/CSA linear supply with 1.5A at 24VDC output and boost circuitry. Both are chosen by the system they feed, so confirm the controller they are serving before ordering.

The Dormakaba R20470 is the SAM RF Emergency Lock Power Supply used with InSync locks and is specified per that hardware. For higher-current needs elsewhere in the same system, the SDC 632 series provides 2 amps and the SDC 634 series provides 4 amps, both regulated and filtered with dual voltage selection, while the Securitron AQS1210 is a 12 VDC 10 amp switching power supply and the Securitron AQL4 is a 12/24VDC switching supply at 4/3 amps.
