BurookHi Norman... I just remembered i didn't let u know.... everything worked out we made both the wired and the remot control opening work... they loved the item (assuming it will hold its own for the next 10 years or so) -
KiranYes I don’t doubt you. Jutai is one of the most confident companies I came across in China

The JUTAI CL20-8L Infrared Safety Beam System is a dedicated protective solution for garage doors and sectional doors. It forms an 8-beam invisible infrared barrier between the emitter and receiver, instantly triggering door reversal or stopping when personnel, vehicles, or objects intrude the detection area. With IP67 protection and rugged aluminum alloy construction, it delivers reliable anti-pinch safety for residential, commercial, and industrial garage/sectional doors.

| Key Function | Garage/sectional door anti-pinch protection + Blanking Mode (anti-false alarm) |
| LED Status Indicators | Transmitter: Steady blue (normal); Fast-flashing red (voltage <9V or >28V) Receiver: Steady red (blocked); Steady blue (unblocked); Flashing blue (misalignment) |
| Installation Hole Dimensions (Unit: mm) | 14, 29, 75, 80, 175, 19.7, 21.4, 259 |
- Targeted Anti-Pinch Protection: Detects people, pets, vehicles, or objects near garage/sectional doors, triggering immediate door reversal to prevent pinching or crushing. 8-beam full coverage eliminates safety blind spots, adapting to standard and large-sized garage/sectional door openings.
- Blanking Mode for False Alarm Prevention: Blocks the first channel without triggering safety responses, adapting to sectional door panel gaps and garage door structural characteristics. Avoids unnecessary interruptions during normal door closure while retaining protection against unintended intrusions.
- Rugged & Environmentally Adaptable: IP67 protection resists rain, dust, and outdoor elements, suitable for indoor/outdoor garage doors and industrial sectional doors. Wide temperature range (-20°C ~ +60°C) ensures stable operation in cold winters, hot summers, or temperature-variable industrial settings.
- Easy Installation & Integration: Color-coded wiring simplifies connection to garage/sectional door control systems. Adjustable mounting brackets fit various door frame structures; 8m/4m cables allow flexible positioning. Intuitive LED indicators enable quick status checks without professional tools.
| Component | Wire Color | Function | Notes |
|---|---|---|---|
| Transmitter | Red | DC12-24V Positive Power Supply | Connect to door control system's power positive terminal |
| Transmitter | Black | Ground (GND) | Connect to power negative terminal |
| Transmitter | Green/Yellow/White | Reserve | No connection required for basic use |
| Receiver | Red | DC12-24V Positive Power Supply | Same as transmitter power connection |
| Receiver | Black | Ground (GND) | Same as transmitter ground connection |
| Receiver | Green | NO/NC Output (Default NO) | Connect to door control system's safety signal input |
| Receiver | Yellow | Configurable NC | Activate via Blanking Mode setup |
| Receiver | White | COM (Common Terminal) | Matching terminal for NO/NC output |
- Complete wiring and power on the system.
- Within 1 minute of power-on, touch the receiver's Green wire to its GND (Black wire) five times.
- Receiver's Red light blinks to confirm activation: Yellow wire switches to NC mode, Blanking Mode enabled.
- Residential garage doors (single-car, double-car)
- Commercial garage doors (parking facilities, retail back entrances)
- Industrial sectional doors (factories, warehouses, loading docks)
- Cold storage sectional doors (refrigerated warehouses, freezer rooms)
| Fault Symptoms | Possible Causes | Solutions |
|---|---|---|
| Receiver's blue light flashes (power-on) | Emitter and receiver misalignment | Readjust positions to ensure parallel alignment |
| Transmitter's red light flashes fast | Power supply voltage <9V or >28V | Stabilize power supply to meet DC12-24V requirements |
| System works, but door has no anti-pinch action | Wiring error | Recheck wiring against the guide; ensure correct connection to door control system |
| Unable to enter Blanking Mode | 1. Light leakage during door descent 2. Bottommost beam blocked by debris 3. Door/obstruction fails to meet minimum continuous blocking distance |
1. Fix door sealing to prevent light leakage 2. Clear debris blocking the beam 3. Adjust door/obstruction to meet distance requirements |
- Keep cables away from high-voltage conductors and door machinery to avoid damage.
- Regularly wipe emitter/receiver lenses with a dry, soft cloth to remove dust, dirt, or condensation.
- Do not bend, twist, or pull cables forcefully; avoid scratching infrared lenses.
- Prevent direct sunlight or infrared light sources from shining on the receiver (avoids false triggers).
- For outdoor installation, ensure the device is shielded from extreme weather (e.g., heavy rain, snow) to extend service life.
