RCI 8310-DSS MultiMag Electromagnetic Lock W/ Door Status Sensor, For Single Doors

The RCI 8310-DSS is a fail-safe electromagnetic lock built for single outswing interior and perimeter doors that need both 1,500 lbf of holding force and remote door-position monitoring. The DSS suffix means Door Status Sensor: a magnet-reed switch with the magnet embedded in the armature for tamper resistance and the reed contacts inside the electronic housing cavity, so your access-control or alarm panel sees the actual physical state of the door independent of local power. That sensor is what separates this SKU from the base RCI 8310. It belongs to the RCI 8 Series Electromagnetic Locks line within the broader RCI Maglocks catalog under Magnetic Locks.

What does the RCI 8310-DSS MultiMag electromagnetic lock do?

The 8310-DSS clamps a single door at up to 1,500 lbf using RCI's MultiMag array. When power drops or an access-control system commands release, the magnet de-energizes and the door opens freely, which is why fail-safe maglocks are the default on egress paths in commercial and institutional buildings. The integrated DSS sends a clean dry contact back to your panel: opened or closed, no power needed at the sensor element. That makes it a one-SKU answer for projects that would otherwise need a separate magnetic door position switch.

What is the difference between the 8310, 8310-DSS, 8310-SCS, and 8310-DSS/SCS?

Plain English: the base 8310 is the lock alone, no monitoring. The 8310-SCS adds a Security Condition Sensor, which reports magnetic bond status (lock secure or compromised). This 8310-DSS adds Door Status Sensor, which reports physical door position. The combined 8310-DSS/SCS reports both. Pair-door applications use the 8320 family. If you want adaptive holding force tuning and BLE diagnostics, see the 8310-IQ-28 IntelliMag.

Is the RCI 8310-DSS UL 294 listed and fire-rated?

Yes. The 8310-DSS carries UL 294 Special Locking Arrangement Component listing under the 6th Edition standard, UL 10C listing as an Auxiliary Lock for fire doors rated up to 1 hour, and California State Fire Marshal listing (CSFM: 3774-2127:0100). That stack means it can be specified into life-safety and code-driven projects without further compliance review.

How do you wire the RCI 8310-DSS for 12VDC or 24VDC?

Voltage is field-selectable, so one SKU covers both 12VDC and 24VDC installations at 280mA. Plug-in wiring terminals and an easy-access wiring cavity cut install time, MOV surge protection guards the coil against transient spikes from strike-and-buzzer circuits, and the residual-magnetism design ensures the door releases cleanly the moment power is cut. Built-in time delay (instant release with relock programmable from 0 to 90 seconds) syncs the lock to delayed-egress and re-lock-on-close logic without a separate timer board.

Mounting hardware and accessories for the RCI 8310-DSS

Out of the box: 5/8" armature plate, 1/4" mounting bracket, hardened steel armature nut, self-drilling Teks fasteners, and the stabilizing 4-bolt drop-stop mounting. Inswing or unusual frame depths add an angle bracket: choose the AB-01, AB-02, or AB-03 based on door reveal. For frameless or tempered glass installations, the AH15 armature plate holder is the DSS-compatible part.
