RCI 8371 28 – Frequently Asked Questions

1) Will an RCI 8371 MiniMag fit a narrow-style aluminum storefront door?
That's what the Surface MiniMag is built for. The 8371 body measures 9-3/8 x 1-7/8 x 1 inches, so it fits narrow-style doors and undersized openings where a full-size mag lock housing has nowhere to sit on the header or the door. It's rated up to 750 lbf holding force in that footprint.
2) Can the RCI 8371 be used on a pair of doors or an inswinging door?
No. The 8371 is a single-door lock for single outswinging interior or perimeter doors. A pair needs two locks (or a double unit), and an inswinging opening needs a different mounting approach entirely, not this surface configuration.
3) Does the RCI 8371 unlock when the power goes out?
It does. The 8371 is fail-safe, meaning the magnet drops and the door is free the instant power is lost. That's the behavior a code official wants on an egress opening, but it also means the door is unsecured during an outage, so if the opening has to stay locked through a power failure a mag lock is the wrong device for it, not this or any other one.
4) Can I use an RCI 8371 on a fire-rated door assembly?
Yes. The 8371 carries a CAN/ULC S104 UL 10C 1-hour fire rating, so it's usable on a 1-hour rated assembly. That's the rating on the lock itself; the door, frame and closer still have to carry their own listings for the assembly to hold.
5) What is the difference between the DSS and SCS options on the RCI 8371?
DSS is a Door Status Sensor, which reports whether the door is closed. SCS is a Security Condition Sensor, which reports whether the magnet is actually holding, not just that the door is shut. You can order the 8371 with neither, DSS only, SCS only, or DSS/SCS together. If your access control panel needs a real locked confirmation for a forced-door or door-held alarm, take the SCS or the combined DSS/SCS; a plain door contact only tells you the leaf is closed.
6) Does the RCI 8371 mag lock have to be handed when I order it?
No handing to specify. The 8371 MiniMag is non-handed, so the same part works on a left- or right-hand outswinging door. What you do need to pick on the order is finish and whether you want sensors.
7) Do the sensors have to be ordered with the mag lock, or can I add them later?
They're a factory build option on the 8371, selected at order time alongside finish. Both finishes, 628 anodized aluminum and 695 dark bronze, are offered in all four sensor configurations, so pick the monitoring you need before the order goes in rather than planning to retrofit it in the field.
8) Is 750 lbs of holding force enough for an interior office or corridor door?
For traffic-control and interior perimeter work, yes. The 8371 is rated up to 750 lbf and is intended for single outswinging interior or perimeter doors. On a high-abuse exterior opening where someone may pull hard against the lock, a higher-force mag (1200 lbf class) is the usual pick; the MiniMag trades force for the compact 1-7/8 inch width that lets it land on a narrow stile at all.
9) What hardware do I need to mount an RCI 8371, and do I need extra brackets?
Self-drilling TEC screws are the fastener, and the unit uses a stabilizing 4-bolt drop stop mount with keyhole slots, so no add-on bracket is needed for a standard single outswing installation. There's an easy-access wiring cavity in the housing for the run. An inswing door or a glass door with no header to bite into is where you'd start pricing separate brackets.
10) What finishes does the RCI 8371 MiniMag come in for matching aluminum storefront?
Two: 628 anodized aluminum and 695 dark bronze. Those are the standard storefront colors, so the lock lines up with clear-anodized or dark bronze frames without a paint job.
11) Is the RCI 8371 rated for commercial use in a hospital or school?
It's a commercial-duty device, and the 1-hour CAN/ULC S104 UL 10C fire rating plus the SCS monitoring option are what institutional specs usually call for on access-controlled openings. Surge protection is built into the unit. Standardizing across a facility is straightforward since the lock is non-handed and comes in one of two finishes.
