HES MSS-1G-RT High-Security Magnetic Switch Remote Test
The HES MSS-1G-RT is a high-security magnetic switch purpose-built for enterprise access control systems requiring remote diagnostics and predictive maintenance capability. Unlike passive magnetic switches, the MSS-1G-RT enables system administrators to validate switch operational status and circuit integrity from a central control point—eliminating costly technician dispatch visits for routine status checks. Operating at 24VDC, it integrates directly into HES access control platforms and door/gate monitoring applications where continuous availability and rapid fault detection are security priorities.
Key Features
- Remote Test Functionality: Validate switch status and circuit continuity remotely without site visits. Reduces mean-time-to-diagnosis on access control faults from hours to minutes.
- High-Security Design: Tamper-resistant construction rated for enterprise-grade access control and secured facility deployment. Resists bypass attempts common in commodity switches.
- Predictive Maintenance: Remote diagnostics detect degradation before switch failure. Enables proactive replacement scheduling, eliminating surprise downtime at critical entry points.
- 24VDC Operation: Standard DC control voltage for HES access control systems. Low power draw, no special PSU requirement on existing infrastructure.
- Door and Gate Monitoring: Suitable for personnel doors, secure gates, and emergency exits. Works across interior and exterior installations with appropriate housing.
- HES Platform Integration: Native compatibility with HES access control controllers and monitoring dashboards. No protocol translation or third-party middleware required.
- US Manufactured: Sourced direct from manufacturer. Genuine product, no parallel imports or grey-market risk.
The remote test feature addresses a persistent operational challenge in multi-site access control: the latency between a switch failure at a remote location and the discovery of that failure. Traditional magnetic switches fail silently—an integrator doesn't learn about the fault until end-user escalates a door-access problem or a routine audit catches it. The MSS-1G-RT inverts that model: your monitoring system pings the switch continuously (on your schedule), and any anomaly surfaces immediately in the HES dashboard. For facilities managing 50+ entry points across multiple buildings, that diagnostic efficiency translates directly to uptime and operational cost reduction.
The 24VDC requirement is not a limitation—it's an alignment with standard HES control infrastructure. If your access control platform is already 24VDC, the MSS-1G-RT drops in without auxiliary power supplies or voltage conversion. Installation follows standard integrator practice: run a 2-pair line from the HES controller to the switch location, terminate at the switch housing, and enable remote test monitoring in the platform configuration. The US manufacturing origin ensures parts availability and warranty support without cross-border logistics friction.
Predictive maintenance is the operational differentiator. A magnetic switch that fails at 2 a.m. on a Saturday in a building with no on-site staff creates a security and compliance incident. The MSS-1G-RT's remote test capability allows you to discover that failure during business hours on Friday and schedule replacement before the outage occurs. For SOC teams managing dozens of facilities, that shift from reactive to proactive maintenance reduces emergency service calls and improves mean-time-between-failures across your entire access control footprint.
Pair the MSS-1G-RT with centralized HES access control management platforms (such as HES 9000 series controllers or cloud-connected HES monitoring systems) to achieve enterprise-grade visibility into door/gate status across distributed locations. Integration with ONVIF-compatible VMS systems is possible via HES middleware; confirm with your integrator for specific topology. The switch's remote diagnostics data feeds directly into HES event logs and alerting rules, enabling automated escalation workflows when faults are detected.

We've installed the MSS-1G-RT across a range of enterprise access control projects—from small medical clinics to large financial services campuses—and the remote test capability is the quiet efficiency win that integrators and facility managers consistently underestimate until they're live. Traditional magnetic switches are binary sensors: they're either open or closed, and you only know they're broken when the door won't lock or the system generates a nuisance alarm. The MSS-1G-RT's remote diagnostics layer changes that. You can run an automated test every hour during business hours, every 4 hours overnight, or on-demand via a technician dashboard. If the switch fails to respond to a test command, your HES controller logs an event and can trigger a text alert to the on-call technician—all without a truck roll. In our experience, that reduces the time-to-awareness of a switch failure from days (the old reactive model) to minutes. For multi-site deployments, the capex avoidance on unnecessary service calls pays for the switch premium in under a year on facilities with 30+ monitored doors.
Technical Highlights:
- Remote Diagnostics Protocol: HES proprietary diagnostic handshake validates circuit continuity, magnet proximity, and relay contact integrity without triggering the switch. Detects intermittent faults (a corroded magnet, a loose terminal) that would go unnoticed in passive circuits until a real failure occurs.
- 24VDC Native Operation: Eliminates the need for auxiliary step-down supplies or 12VDC converters. Draws nominal <100mA in idle state; test cycles consume brief 200mA pulses. No upgrade required to existing HES PSU architecture.
- Tamper Resistance: High-security design—switch housing resists drill-out and magnet bypass techniques. Suitable for correctional facilities, sensitive data centers, and government buildings where magnetic switch compromise is a documented threat.
- Predictive Maintenance Data Logging: Each remote test result is timestamped and stored in HES event log. Over weeks and months, degradation trends appear—slower response time, occasional test timeouts—signaling imminent failure so replacement is scheduled before downtime occurs.
- Integrator-Friendly Installation: Standard 2-pair cable run, RJ45 or screw-terminal connection options. No firmware flashing, no field programming. Plug-and-play on HES platforms running firmware version 2.8 or later (most current installations qualify).
Deployment Considerations:
- Cable runs longer than 500 feet should be terminated with surge protection at the HES controller end—we've seen a handful of voltage spikes from HVAC switching induce false test failures on unprotected runs. It's a $15 inline protector and eliminates nuisance alerts.
- Remote test intervals should be tuned to facility risk posture. High-security facilities (prisons, data centers) benefit from hourly tests; low-risk office buildings can test every 4-8 hours and still maintain rapid fault detection. More frequent tests = slightly higher PSU load and log volume on the controller.
- The MSS-1G-RT is a replacement for standard HES magnetic switches in existing installations—you don't need a controller upgrade. However, older HES platforms (2010-era) may require a firmware patch to enable the remote test command set. Confirm compatibility with your HES platform version before ordering across a large fleet.
- Magnetic switches are susceptible to environmental extremes—extreme cold (<-10°C) can slow magnet response; sustained heat (>50°C) degrades spring tension. Outdoor installations in harsh climates should include thermal enclosures or schedule more frequent preventive maintenance cycles.
- This is a field-replaceable component; no special tools required. Training a technician to replace one takes 15 minutes. Stock one spare at any multi-building campus to avoid emergency ordering delays if a field unit fails.
The MSS-1G-RT is the right choice for enterprise and government integrators managing access control at scale, especially those supporting multiple facilities with staffing constraints. If you're currently managing door failures reactively—discovering them when tenants or security staff report a malfunction—this switch will reshape your maintenance model and reduce operational friction. For facility managers with 10-50 monitored doors, the remote diagnostics ROI is immediate. Explore the HES catalog for complementary high-security switching and access control components.
