RCI 3525 – Frequently Asked Questions

1) Will the RCI 3525 rack handle lock fit a standard 19-inch server rack cabinet door?
The 3525 rack handle measures 1-1/2" W x 8-1/4" H x 1" D (37mm x 210mm x 24.5mm), so it takes the standard swing-handle pocket on a rackmount enclosure door and leaves the rack rails clear. It's non-handed, so the same unit works on a left or right hinged cabinet door and on front or rear doors. Allow clearance behind the handle for the wire harness run and for service access later.
2) What power supply do I need to run an RCI 3525 electronic rack handle?
Field-selectable 12 to 24VDC, drawing about 200mA typical and under 200mA at 12VDC, with standby down to 50mA max. Any regulated DC supply in that range sized for the number of handles will run it, and the 3525 is also Power over Ethernet compatible if you'd rather feed it from the network switch than run a separate DC home run to each cabinet. Output signal contacts are rated 100mA max load, so switch a relay rather than a load directly off them.
3) Which RCI 3525 reader version do I order for my existing badges - 125 kHz prox or HID iCLASS?
Four builds are offered: a standard electronic handle with no reader (12VDC to 24VDC, black), a proximity reader version for 125 kHz credentials, an iCLASS version for 13.56 MHz, and a dual frequency version that reads both. If your facility is still on 125 kHz prox cards, order the proximity handle. If you've moved to 13.56 MHz smart credentials, order the iCLASS one. Mid-migration, or a datacenter with tenants on different card technologies, is exactly what the dual frequency handle is for. The no-reader version is the one to buy when the cabinet is being controlled entirely from an upstream access control panel.
4) What happens to an RCI 3525 rack lock if the power drops?
It stays locked. The 3525 is fail-secure, so a power loss on the cabinet leaves the equipment secured rather than releasing the handle. Access during an outage is through the mechanical override, a high security DIN lock built into the handle, so keep those keys where your on-call staff can reach them. That's the opposite behavior from a fail-safe egress lock, and it's the right choice for equipment enclosures where nobody is trapped inside.
5) Can I tie an RCI 3525 rack handle into my building access control system?
Yes, over Wiegand. The 3525 reader handles put out Wiegand, which is what most access control panels take on their reader inputs, so cabinet reads land in the same system and audit trail as your door readers. Separately, the integrated lock sensor gives a monitoring output plus a multi-color LED at the handle, so the panel can see lock status and a tech standing at the rack can see it too without pulling up software.
6) Can an Adams Rite 4605 transformer power an RCI 3525 rack handle lock?
No - the two speak different current. The RCI 3525 rack handle lock runs on field-selectable 12-24VDC at roughly 200mA, with Power over Ethernet compatibility as an alternative feed. The Adams Rite 4605 is a transformer that takes 115 VAC in and puts 12/24 VAC out at 40 volt-amps. The voltage numbers look like a match, but the 4605 output is alternating current and the 3525 needs DC, so it is not the supply for this lock. Feed the 3525 from a filtered DC supply at 12 or 24VDC, or from PoE.
7) Will DynaLock 7551 proximity cards work with an RCI 3525 rack handle lock?
It depends on frequency, and that is the only question worth asking. The RCI 3525 rack handle lock is ordered with a 125 kHz proximity reader, a 13.56 MHz iCLASS reader, or a dual frequency reader, so the credential has to match the reader you specify. The DynaLock 7551 is a proximity card and the DynaLock 7561 is the same technology in a tag format for a keyring or badge clip - both are credentials only, not readers, so they do not replace any part of the 3525 itself. If your facility is already carrying 13.56 MHz iCLASS badges, specify the 3525 with the iCLASS reader; if you are running two credential populations during a changeover, the dual frequency reader version reads both.
8) Is the RCI 3525 a full replacement handle or just an add-on lock for an existing rack handle?
It's the complete swing handle assembly, not a bolt-on to a handle you already have. The 3525 replaces the mechanical rack handle in the door cutout and brings its own gear motor driven latching mechanism, reader, sensor and DIN key override. Wire harness and mounting hardware kit ship with it, so the only thing you're sourcing separately is the DC power or PoE feed and the cable back to your access control panel.
9) I need credentials to go with an electronic rack lock - what card or fob works with a 125 kHz proximity reader?
For the proximity version of the 3525, which reads 125 kHz prox, the credential is a standard prox card or fob. ZenSupply carries the DynaLock 7551 Series proximity card and the 7561 Series proximity tag for keyring use, and either format is the usual pairing when you're issuing badges to techs who need cabinet access. The iCLASS build reads 13.56 MHz instead, so 125 kHz cards won't present to it.
10) Can I power an RCI 3525 rack handle from 115VAC line voltage?
Not directly. The handle wants 12 to 24VDC, so you need a supply between the wall and the lock. If you're building the power feed yourself, the Adams Rite 4605 transformer steps 115 VAC down to 12/24 VAC at 40 volt-amps, which is a common front end ahead of a DC access control power supply. Simplest route in a rack, though, is the 3525's Power over Ethernet compatibility, which lets the switch feed the handle and skips the separate power run entirely.
11) I need to know whether a lock is secured and report it back to my access control system - is the RCI 3525 the right choice, or do I want a monitor switch kit?
That turns on what you are securing. The RCI 3525 rack handle lock is a rackmount enclosure handle with an integrated lock sensor, multi-color LED for local status, a remote monitoring output, and Wiegand output for connection to an access control system - the credential reader, the latch, and the status reporting all arrive as one assembly for the cabinet. If the opening you are monitoring is a door on an existing mortise lock, the Command Access SCHLBMKIT-ML is a different route: a field installable latchbolt monitor switch kit for Schlage L9000 mortise locks in an SPDT configuration, which adds status reporting to a lock already hung without changing how it is operated. Use the 3525 where the enclosure needs the lock, the reader, and the monitoring together; use a monitor switch kit where the mechanical lock stays and only the signal is missing.
12) Is the RCI 3525 rack handle rated for commercial or datacenter use rather than home use?
Commercial. The 3525 is built for equipment security in datacenters, telecom rooms, IT infrastructure, research facilities and secure storage racks, where the requirement is a per-cabinet audit of who opened what. It is not a residential product, and the gear motor mechanism plus integrated sensor set is aimed at installations where the cabinet is monitored continuously.
13) How do I know from across the room whether an RCI 3525 rack cabinet is locked?
A multi-color LED on the handle gives local status, so a tech walking the row sees lock state without opening a laptop. The same integrated lock sensor feeds a remote monitoring output, so the state also reports back to the head end. That combination is the reason to spend on this handle over a plain keyed swing handle: you find out a cabinet was left unsecured while you can still do something about it.
