Safety Light Grid System for Automatic Doors with Waterproof Aluminum Housing

Core Specifications (Parameter Table)

Key Advantages (Clear Points)

1. Waterproof Aluminum Housing

• Aluminum alloy construction ensures durability, corrosion resistance, and effective waterproofing, paired with IP67 rating.
• Withstands rain, dust, and moisture, suitable for outdoor-installed automatic doors or humid industrial environments.

2. Targeted Automatic Door Protection

• 8-beam light grid covers full door opening height (1729mm), eliminating safety blind spots and preventing pinching of hands, limbs, or objects.
• Instant response to beam interruption, matching the operational speed of automatic doors to avoid safety lags.

3. Blanking Mode for False Alarm Prevention

• Blocking the first channel does not trigger safety responses, adapting to automatic door gap structures.
• Avoids unnecessary door reversal during normal closure while retaining protection against unintended intrusions.

4. Easy Installation & Operation

• Color-coded wiring simplifies connection to automatic door control systems (details in Wiring Guide).
• Adjustable mounting brackets fit various door frame structures; intuitive LED indicators enable quick status checks.

Wiring Guide (Standardized Table)

Critical Warning

• Do NOT connect NO/NC terminals (Green/Yellow wires of receiver) to the power supply positive terminal—this will damage the optical relay.

Blanking Mode Activation Steps

1. Complete wiring and power on the system.
2. Within 1 minute of power-on, touch the receiver’s Green wire to its GND (Black wire) five times.
3. Receiver’s Red light blinks to confirm activation: Yellow wire switches to NC mode, Blanking Mode enabled.

Application Scenarios (Targeted List)

• Industrial automatic doors (fast doors, roller shutter doors, sectional doors)
• Commercial automatic doors (shopping malls, office buildings, retail stores)
• Outdoor automatic doors (parking facilities, logistics center entrances)
• Special environment automatic doors (cold storage, humid workshops)

Troubleshooting (Problem-Solution Table)

Usage & Maintenance Caveats (Key Reminders)

• Keep cables away from high-voltage conductors and door machinery to avoid damage or interference.
• Regularly wipe emitter/receiver lenses with a dry, soft cloth to remove dust, moisture, or dirt.
• Do not bend, twist, or pull cables forcefully; avoid scratching the aluminum housing or infrared lenses.
• Prevent direct sunlight or infrared light sources from shining on the receiver (avoids false triggers).
• For outdoor installation, ensure the device is fixed firmly to resist wind and vibration.
