RCI 171HD Electromagnetic Lock for Hazardous Locations with Continuous Monitoring

Professional Fail-Safe Magnetic Lock with Continuous Monitoring for Hazardous Location Applications

The RCI 171HD electromagnetic lock provides fail-safe security for fire exit doors in hazardous locations with continuous monitoring capability for open/close status and unauthorized entry detection. This surface-mounted magnetic lock powers down when signaled by appropriate door control units and accommodates most doors and frame conditions without requiring filler plates or special brackets. UL listed for both door holder and fire alarm system applications with comprehensive hazardous location certifications.

Professional Features & Benefits

  • Hazardous Location Certification: UL228 tested door holder (Category FDGF, File E146590) and ANSI/UL864 tested releasing device (Category SZNT, File S5020) for safe operation in hazardous environments.
  • Continuous Monitoring Capability: Real-time monitoring of door status and unauthorized entry attempts provides enhanced security feedback to control systems.
  • Fail-Safe Operation: Automatically releases when power is removed, ensuring safe egress during emergencies while maintaining security during normal operation.
  • Universal Installation Design: Accommodates most door and frame conditions without requiring filler plates or special mounting brackets for simplified installation.
  • Fire Exit Door Compatible: Specifically designed for fire exit door applications with appropriate safety certifications and fail-safe operation.

RCI 171HD – Frequently Asked Questions

1) Will the RCI 171HD magnetic lock work on an inswing door, or does it only mount on the push side?
Both. The 171HD comes in a push side mount version and a pull side mount version, and the pull side option ships with the "Z" bracket inswing assembly kit already included, so you don't have to source the bracket separately for an inswing opening. Pick the mount that matches which way the door swings away from the magnet, because ordering the push side version for an inswing door leaves you without the Z bracket.
2) Does the RCI 171HD maglock stay locked or release when the power drops?
It releases. The 171HD is a fail-safe device, so cutting power drops the magnet and the door is free to open. That's what makes it usable on a fire exit door tied into a fire alarm or access control release, and it's also the thing to understand before you specify it for a secure perimeter opening: any power loss is an unlocked door. If the requirement is that the opening stays locked through a power failure, a maglock is the wrong family of product entirely, since electromagnetic locks are fail-safe by their nature.
3) Is the RCI 171HD UL listed for use on a fire exit door?
Yes, on two counts. The 171HD is a UL228 tested door holder under Category FDGF, File E146590, and an ANSI/UL864 tested releasing device under Category SZNT, File S5020. Those are the two listings a fire alarm tie-in usually needs: the door holder listing covers holding the door, and the UL864 releasing device listing covers dropping it on an alarm signal. It's built for fire exit doors in hazardous locations.
4) Is the RCI 171HD rated for a classified or explosive atmosphere like a refinery or chemical plant?
The 171HD is the hazardous locations version of RCI's magnetic lock, carrying hazardous location certification for use in classified areas such as chemical processing plants, petroleum refineries and storage, and manufacturing with explosive atmospheres. It is a commercial-duty device. The install still has to follow local electrical code for hazardous location work, including hazardous location rated conduit and connectors on the wiring runs.
5) Can one RCI 171HD maglock secure a pair of doors?
No. The 171HD is a single door application, one magnet and one armature per leaf. For a pair, you'd order a unit per door and give each one its own power and monitoring run, or move to a double-door magnetic lock built for the job.
6) Do I need filler plates or special brackets to mount an RCI 171HD magnetic lock?
No. The 171HD is surface mounted to the frame header and accommodates most door and frame conditions without filler plates or special brackets. The one thing you do need to get right up front is the mount side: the pull side version carries the Z bracket inswing kit, the push side version doesn't need one.
7) What does continuous monitoring on the RCI 171HD actually report back to my access control panel?
Door open/close status and unauthorized entry attempts. The monitoring output feeds those states to a control system in real time, so a head end can tell the difference between a door that was legitimately released and one that was forced. If you're wiring it, that's an additional set of conductors beyond the lock power run, and the monitoring connections get configured to whatever your control system expects.
8) Does the RCI 171HD magnetic lock need a card reader or access control system to work?
It needs something to signal it. The 171HD powers down when signaled by an appropriate door control unit, so the magnet holds as long as it has power and releases when a reader, request-to-exit device, or fire alarm interface cuts that power. The lock itself supplies no credential reading. Budget for the power supply, the release device, and in a classified area the hazardous location rated conduit for both the lock and monitoring wiring.
