Mantrap Turnstile, Man-Trap Security Gate
The Madoors USA MDRS-MNTRAP-500 Mantrap Turnstile and Man-Trap Security Gate is a high-security Circlelock door system consisting of two single-wing cambered side-sliding doors that allow only defined, individually authorized users to pass through one at a time — preventing tailgating, piggybacking, and unauthorized entry through the most critical access points in security rooms, computer system rooms, data centers, and any high-security facility where individual authorized access control is the operational requirement. Weight sensors inside the cabin confirm that only one person is present before the second door opens — preventing the entry of two persons simultaneously where one is authorized and one is unauthorized. When coupled with biometric and access control devices, the MDRS-MNTRAP-500 supports regulatory compliance, risk and liability reduction, and accurate access metrics collection.
TECHNICAL SPECIFICATIONS
The Madoors USA MDRS-MNTRAP-500 operates in a precise sequential access sequence. The authorized person presents their credential — card, PIN, or biometric — to the reader at the outer door. The first door opens and the person enters the Circlelock cabin. The first door closes immediately behind the person, locking them within the cabin. Weight sensors check the person's weight — confirming that only one person is present in the cabin. If the weight is within the single-person limit, the system confirms no unauthorized simultaneous entry. The second door then opens, allowing the authorized person to proceed into the protected area.
If the weight sensor detects weight exceeding the single-person threshold — indicating two persons have entered the cabin simultaneously — both doors remain closed and locked, the unauthorized entry attempt is recorded and alarmed, and security personnel are notified. This weight-based detection is the technical mechanism that prevents the most sophisticated unauthorized entry attempt — the authorized person being accompanied or coerced by an unauthorized person.
The small compact form factor of the MDRS-MNTRAP-500 allows installation in existing buildings at security rooms, computer system rooms, server rooms, and any internal high-security access point — without the major structural works required for full-scale security portal installations. The various surface finishing material options complement the architectural character of the installation environment.
Multiple in-cabin sensors beyond weight detection can be equipped according to the required security level — metal detection sensors, height verification sensors, and behavioral sensors provide additional unauthorized access detection capability for the highest-security applications.
KEY FEATURES
Sequential Two-Door Access — Complete Tailgating Elimination
The sequential two-door access principle — outer door opens on authentication, outer door closes and locks before inner door opens — physically eliminates the tailgating vulnerability of standard single-door access control systems. A tailgater following an authorized person through a standard door cannot follow into the Circlelock because the outer door locks with only one person inside. This sequential physical separation is the definitive mechanical solution to tailgating and piggybacking — the access control cannot be bypassed by following authorized persons.
Weight Sensor — Simultaneous Multi-Person Detection
The weight sensor inside the Circlelock cabin provides the detection of simultaneous two-person entry — where an authorized person is accompanied by an unauthorized person who entered the cabin at the same time as the authorized credential presentation. The predetermined weight limit is set for the normal range of single-person body weight — any reading above this threshold indicates two persons in the cabin, triggering lockdown of both doors and a security alert. This sensor directly prevents the coerced or consensual two-person simultaneous entry that badge-sharing attacks rely on.
In-Cabin Multi-Sensor Configuration — Adjustable Security Level
The configurable in-cabin sensor package allows the security level to be matched to the specific threat assessment of each installation — standard security positions use weight sensors alone, while higher-security positions add metal detection, height verification, and behavioral sensors to the cabin assessment. This configurable security level allows the same MDRS-MNTRAP-500 platform to serve a wide range of security requirements without requiring different hardware for different security levels.
Compact Design — Internal Building Installation
The small, compact form factor allows the MDRS-MNTRAP-500 to be installed at internal building access points without the space requirements and structural works of full-scale security portals — security rooms, computer system rooms, server rooms, and any high-value internal area can be protected with a mantrap installation that fits within the standard corridor and room entry dimensions of existing buildings.
Biometric & Access Control Integration — Regulatory Compliance Support
The full integration with biometric readers — fingerprint, iris, face recognition — card readers, PIN pads, and building access control systems allows the MDRS-MNTRAP-500 to be incorporated into the facility's complete security management infrastructure. This integration supports regulatory compliance for data protection, financial services, pharmaceutical, and government facility standards that require individual authenticated access control at sensitive system and data locations — accurate access metrics confirm who accessed each location and when for audit and compliance reporting.
Anti-Ram High Security Construction
The high-security anti-ram construction of the Madoors USA mantrap entrance provides physical resistance to forced entry attempts — the Circlelock doors are engineered to resist the ram and impact attacks that could otherwise allow unauthorized access to the protected area even if the access control system is bypassed. High security revolving doors and portals have been proven to prevent intrusion in the most critical access scenarios.
Surface Finishing Options — Architectural Integration
The various surface finishing material options allow the MDRS-MNTRAP-500 to complement the architectural design quality of the installation environment — stainless steel, glass, powder-coated metal, and wood veneer finishes are available for integration with the interior design character of corporate, government, and institutional high-security facilities where the security installation must maintain the visual quality of premium environments.
Pressure Relief — Employee Security Confidence
The mantrap system takes pressure off employees by eliminating the social engineering pressure to allow tailgaters through a standard door — with a mantrap, the physical system prevents two-person simultaneous entry regardless of any social pressure on the authorized person. This pressure relief directly reduces the human factor vulnerability at high-security access points where employees may feel compelled to hold doors for colleagues.
OPERATIONAL ACCESS SEQUENCE
Step 1 — Outer Door Credential Authentication
The authorized person presents their card, PIN, or biometric credential at the outer door reader. The system verifies the credential against the access control database.
Step 2 — Outer Door Opens
On successful authentication, the outer single-wing cambered sliding door opens. The authorized person enters the Circlelock cabin.
Step 3 — Outer Door Closes & Locks
The outer door closes and locks behind the person — the person is now contained within the Circlelock cabin. No second person can enter.
Step 4 — Weight Sensor Assessment The weight sensor measures the cabin occupant weight. Single-person weight — authorized entry proceeds. Double-person weight — both doors remain locked, alarm triggered, security notified.
Step 5 — Inner Door Opens
The system confirms single authorized occupant. The inner single-wing cambered sliding door opens and the authorized person passes through to the protected area.
Step 6 — Inner Door Closes
The inner door closes behind the authorized person. The system resets to ready state for the next access event.
Unauthorized Entry Attempt Lockdown — If weight or any in-cabin sensor detects unauthorized conditions, both doors remain closed and locked. The attempt is recorded with timestamp and credential data. Security personnel receive immediate alert.
ASSEMBLY & INSTALLATION SEQUENCE

Access Control & Biometric Integration
Card reader, PIN pad, and biometric reader are connected to the building access control system. Authentication database is configured for the authorized user population. Access metrics recording is confirmed active.
