Installing An RCI 3590 Prox 'N Lock

No visible keyway or dial is needed to operate this cabinet lock. The outer surface of the drawer or door remains unblemished with the lock mechanism hidden inside. RFID cards or keyfobs open the lock.

When the locking pin is installed into the lock body, the centerline for the locking pin retainer screws was found to be 1 5/8” away from the back edge of the lock body. Make sure the locking pin is in line with the lock body locking socket and the locking pin centerline is 1 5/8” back from the front of the cabinet structure, then mark hole locations for locking pin mounting screws.

The drawer unit for this application was 5” deep. The drawer support rail prevented use of a standard 1/4” drill motor. The solution was to use a 90-degree attachment to drill the locking pin retainer screw holes. An offset screwdriver was used to install the screws.

The locking pin mount provides both sideways and in/out adjustment. First, loosen the in/out adjustment screws and move the locking pin to its full outward adjustment position. Slowly close the drawer to test for locking pin alignment issues. The locking pin is secured in the chassis by an expansion spring, plus the locking pin passes through an enlarged hole in the locking pin chassis. Therefore the exact location of the locking pin is not critical because the pin has partial horizontal and vertical movement so it can “find its way” into the lock body socket.

Continue adjustments until there is approximately 1/8” free play when the drawer is locked. Test the installation several times with a user card or keyfob. Each time the card or fob is inserted near the 3590 location, a chime should sound indicating that the lock is unlocked and the drawer or door can be opened. An audible warning is sounded if the battery is near failure. At complete battery failure the RCI 3590 reverts to a “fail unlocked” state.

It sometimes takes longer to explain an installation than to actually do one. Only six screws are needed to install an RCI 3590. Except for making the required 1/2” shim, actual installation time took less than 15 minutes.

Our RCI 3590 was installed on the front of a wooden cabinet drawer. Installations can also be done in other ways such as on the rear surface of the drawer or on metal cabinets. If the cabinet lock is mounted either in a remote section of the cabinet or on a steel cabinet, an optional external reader can be used. The external reader is plugged into the lock body and a small hole is drilled at the front of the cabinet. When the user card or keyfob is placed near external reader, an unlocking signal is sent back by wire to the 3590 lock unit.

Other optional accessories include an external antenna and a kit for mounting the 3590 on glass showcase units. A special alarm version of the RCI 3590 Lock N’ Prox is also available. The 3590ACRD package contains two user cards and the 3590AFOB contains two keyfobs in place of the user cards. Alarm will sound if door or drawer is either held open for extended periods or if the lock is forced open. Factory order functions include time delay, silent operation and toggle operation.

The RCI 3590 Lock N’ Prox cabinet lock is easy to install, simple to program and provides an ideal solution when security needs to be concealed. For further information contact your local locksmith distributor or: Rutherford Controls, telephone 800-265-6630 or e-mail
