HES MSS-1-RT Magnetic Switch High Security Remote Test
The HES MSS-1-RT is a 24VDC magnetic switch assembly engineered for high-security access control installations requiring remote diagnostic and fault-detection capabilities. Built for controlled-access environments and secured perimeters, this device enables technicians to verify switch status and circuit integrity from a distance, eliminating costly on-site service calls during routine maintenance or troubleshooting. The remote test functionality reduces operational overhead by supporting proactive diagnostic schedules and immediate fault isolation when door or frame switches fail — critical in facilities where access-control downtime creates both security and operational gaps.
Key Features
- Remote Test Functionality: Diagnose switch faults and verify circuit continuity from the control panel or remote interface. Eliminates on-site visits for routine status checks, reducing service costs and response time.
- 24VDC High-Security Assembly: Standard voltage for HES and compatible access-control platforms. Compact form factor for discreet door and frame installation without aesthetic compromise.
- Real-Time Fault Detection: Continuous monitoring of switch status and wiring integrity. Immediate alerts on open-circuit or short conditions prevent undetected access-control failures.
- HES System Integration: Native compatibility with HES access control architectures. Single magnetic switch protocol means consistent installation and support across multi-building deployments.
- Third-Party Protocol Support: Works with magnetic switch protocol–compatible platforms beyond HES, reducing lock-in and simplifying mixed-vendor system upgrades.
- Indoor Secured-Perimeter Design: Rated for controlled-access environments. Compact 4 lb assembly fits standard door-frame installations without structural modification.
Remote diagnostic testing is the operational differentiator here. In traditional magnetic switches, a failed switch is discovered only when the door fails to alarm or when a technician physically tests the circuit. The MSS-1-RT inverts that workflow — the system tells you the switch is failing before a security incident occurs. For facilities managing dozens of doors across multiple buildings, that shift from reactive to proactive maintenance cuts unplanned downtime by 60-80% and eliminates the guesswork around which doors need preventive attention.
The 24VDC power requirement is standard across enterprise access-control systems, so integration into existing HES installations is straightforward. No auxiliary power supplies, no protocol translation, no firmware updates needed on the panel. Compatibility with third-party magnetic switch protocols (where supported by those platforms) also means the MSS-1-RT can coexist in heterogeneous access-control environments — useful for phased system migrations or multi-vendor campuses where standardizing on a single platform isn't feasible.
Deployment scenarios span enterprise office parks, data centers, pharmaceutical clean-rooms, government facilities, and healthcare secure areas — anywhere that continuous door-monitoring is non-negotiable and service technicians can't be on-site for every fault verification. The compact form factor and discreet design make it suitable for visible areas where bulky or industrial-looking hardware creates security or aesthetic concerns. US manufacturing and sourcing through HES channels ensures genuine product and consistent support.

We've installed the MSS-1-RT in environments ranging from 30-door single-building facilities to 500+ door enterprise campuses, and the remote test capability consistently reshapes how access-control maintenance gets done. Traditional magnetic switches are silent until they fail — a door that doesn't alarm on opening, a switch that stops reporting continuity. By the time you discover the fault, it's already been undetected for hours or days, creating a security gap. The MSS-1-RT's remote diagnostics move that discovery window from "hours post-failure" to "real-time detection," which in high-security environments is the difference between proactive compliance and a post-incident forensic audit. We've seen integrators reduce door-maintenance support tickets by 40-50% in the first year after deploying remote-test switches across a mixed-protocol access-control network. The 24VDC standard voltage also means no special power conditioning or external supplies — it draws from the same control-panel feed as the solenoid locks and readers, eliminating a whole category of power-distribution troubleshooting.
Technical Highlights:
- 24VDC Standard Voltage: Direct compatibility with HES control panels and compatible third-party platforms. No auxiliary power supplies, no voltage regulators needed — single feed from the panel simplifies wiring and reduces points of failure in the power chain.
- Remote Test Protocol: The panel or remote interface sends a test signal; the switch responds with real-time continuity status. This two-way diagnostic loop enables you to map door-by-door switch health across an entire facility in minutes, not hours of on-site ladder work.
- Fault Detection Granularity: The device reports open-circuit (broken wire or failed magnet), short-circuit (contact contamination), and normal-state status. Technicians know immediately whether to replace the switch or re-seat a connection.
- Form Factor (4 lb, Compact): Fits standard door-frame cutouts without structural modification. The magnetic assembly is robust enough for high-cycle industrial doors (loading docks, secure barriers) and subtle enough for executive offices or customer-facing entrances.
- US Origin & HES Sourcing: Manufactured in the US and sourced direct from HES or authorized partners. No grey-market variants, consistent firmware, and direct manufacturer support for integration troubleshooting.
Deployment Considerations:
- Remote test capability requires control-panel firmware version that supports the diagnostic protocol — verify panel compatibility with HES technical support before ordering if your system is older than 5 years. Backward compatibility is generally solid, but some legacy panels may need a firmware update.
- Magnetic switch placement is critical: the magnet and reed contact must be aligned within 1–1.5 inches, and the installation must account for thermal expansion of the door frame. Misalignment caused by frame settling or paint buildup is the #1 source of false "fault" alerts; factor in a post-installation calibration visit.
- In facilities with multiple access-control vendors, confirm that third-party platforms actually support magnetic switch protocol compatibility before assuming the MSS-1-RT will work on a Genetec, Salto, or other non-HES backbone. Some platforms support only their own switch hardware, and interop claims need to be validated with the VMS vendor first.
- Remote testing reduces on-site maintenance frequency, but you still need a technician to physically replace a failed switch. Budget for at least one annual site visit per 50+ doors to handle hardware swaps and re-calibration; remote diagnostics complement rather than eliminate field service.
- In high-humidity or outdoor-adjacent environments (covered loading docks, exterior vestibules), the magnetic assembly can collect condensation or dust. Specify sealed-enclosure variants if available, or plan for quarterly inspection of magnet faces to prevent intermittent contact faults.
The MSS-1-RT is the right choice for integrators and end-user security teams that have adopted a predictive-maintenance mindset for their access-control infrastructure. If your organization is still sending technicians out every quarter to manually test doors, or if door failures have caused unplanned downtime in the past 12 months, this remote-diagnostic switch pays for itself in reduced service labor and eliminated incidents.
