I. Product Overview: More Than Just Teaching, It's a Microcosm of a Real Engineering Environment
1.1 What is it?
The MR576E is an integrated security system platform centered around a Schneider Electric logic controller. It integrates multiple security components used in real-world engineering projects into a single portable training device:
Video intercom access control system (one-to-two)
Wired magnetic door switch
Wired infrared + microwave dual-technology detector
Audio-visual alarm
This system uses industrial-grade hard-wired signals and standard communication protocols, enabling real-time monitoring, intrusion detection, logical judgment, and active deterrence of dual-zone entrances and exits—functions directly addressing the real security needs of commercial and industrial sites.
1.2 Core Features
Simple aluminum profile structure – easy to assemble and disassemble, stable structure
Equipped with casters – easy to move in the laboratory or workshop
All industrial-grade components, not software simulation, not a watered-down teaching board
 
II. Technical Specifications
2.1 Power Requirements
Power Supply: Single-phase three-wire AC 220V ±5% 50Hz
2.2 Dimensions and Weight
* Dimensions: 845mm (W) × 710mm (D) × 1710mm (H)
Weight: Less than 30kg
This size is suitable for standing operation, with a moderate height and weight that is manageable for one person to push.
 
III. Component Composition and Functions
3.1 Main Structure
The main body of the device consists of three parts: the control unit, the equipment frame, and four casters. The control unit houses all electrical components, the frame provides installation and wiring space, and the casters ensure flexible movement.
3.2 Control Section – The True Core
The control section is the soul of this platform, and its main components include:
Circuit Breakers (3):** Used for power distribution and overload protection.
Schneider Logic Controller (1):** The brain of the entire system, responsible for receiving sensor signals, executing logical judgments, and outputting control commands.
Switching Power Supply (1):** Provides a stable DC operating voltage for each module.
One-to-Two Video Doorbell System (1):** Supports one door station with two indoor units, simulating multi-entry or multi-resident scenarios.
Human Motion Sensor Switch (1):** Used to detect personnel movement.
Wired Door Sensor (1):** Detects the open/closed status of the door.
Wired Infrared + Microwave Dual-Technology Detector (1):** One of the highlights of the entire system, employing both infrared and microwave technologies. An alarm is only triggered when both technologies are simultaneously activated, significantly reducing the false alarm rate.
Arm, Disarm, and Reset Buttons (1 each):** Used for system status control.
Incandescent Lamp (1):** Can be used as an alarm linkage output indicator or for lighting logic demonstration.
Audible and Visual Alarm (1)** One alarm – emits a high-decibel sound and flashing light when triggered.
One electric lock – access control actuator.
Four European-style sockets – for powering external devices.
3.3 Included Accessories
Besides the main unit, the accessory list is also very comprehensive:
One waterproof plug.
One Schneider PC to USB programming cable (model SR2USB01) – this is a key tool for connecting the computer and the logic controller, used for downloading programs and online monitoring.
Four access cards.
One USB flash drive (usually contains data or software).
The SR2USB01 programming cable is particularly important; with it, students can truly program, debug, and modify the logic of the Schneider controller.
 
IV. Overview of Experiments
The MR576E comes with a detailed experimental guide. The following are some core experimental projects:
Experiment 1: Doorbell One-to-Two Test Experiment
Learn how to make one door station communicate with two indoor units simultaneously. This is a typical application scenario for apartments, double-entry doors, or small offices.
Experiment 2: Human Body Induction Switch Experiment
Master the wiring and parameter adjustment of passive infrared (PIR) sensors, and understand the practical setting methods for concepts such as sensing delay and sensitivity.
Experiment 3: Wired Infrared Microwave Dual-Technology Detector Experiment
This is the most representative experiment in the entire setup. You need to correctly connect the infrared and microwave signals and write a program in the logic controller that requires both conditions to be met simultaneously to trigger an alarm. Through this experiment, students can deeply understand the essential differences between single-technology and dual-technology detectors, and why the latter is more favored in professional security systems.
In addition, there are more experiments such as arming/disarming logic experiments, sound and light linkage experiments, and access control and alarm system integration experiments. Detailed steps can be found in the experiment guide.
 
V. What is the real value of this platform?
In today's increasingly widespread wireless communication, many people ask: Why learn hardwiring?
The answer is simple—reliability.
Industrial-grade security and control systems have much higher requirements for stability, anti-interference capabilities, and response delay than home appliances. Hardwiring eliminates the risk of wireless signal interference or blockage, and troubleshooting is also more intuitive. The MR576E offers students more than just wiring training; it provides a complete engineering mindset:
Learn to read electrical drawings and terminal block diagrams
Learn to use a multimeter to troubleshoot open circuits, short circuits, and loose connections
Learn to write and debug safety logic on a PLC
Learn to link multiple subsystems (access control, detection, alarm) together
Whether you are a vocational school training instructor or a training manager within a company, the MR576E provides a realistic, safe, and repeatedly operable engineering platform.
