High-Power Emergency Tri-Proof Light: Dual-Use & Four-Wire System Wiring Guide
Jan 27, 2026
Product Introduction & Wiring Guide
This is the standard high-power emergency tri-proof light that integrates two functions in one: normal lighting when powered and emergency lighting when power is cut off. It effectively solves the annoying problem of unintended emergency lighting activation when the light switch is turned off, making it a reliable choice for commercial, industrial, and fire protection scenarios.
Key Feature: Four-Wire System
The light adopts a professional four-wire system, which is the core to ensuring stable performance. The four wires are defined as follows, with strict wiring requirements to guarantee proper operation:
Detailed Wiring Instructions
Fire-Fighting Live Wire: Connect to the dedicated fire-fighting power live wire. This wire is responsible for supplying power to the emergency backup module and maintaining charging status.
Neutral Wire: Connect to the universal neutral wire of the power circuit. It is essential for the normal operation of both the lighting and charging functions.
Lighting Switch Wire: Connect to the wall switch or control switch of the lighting circuit. Crucial Note: This wire must be in the same phase as the fire-fighting live wire to avoid misoperation (e.g., emergency lighting turning on when the switch is off).
Ground Wire: Connect to the protective ground wire of the circuit. It ensures electrical safety and prevents electric shock hazards, complying with international electrical safety standards.
Working Principle & Advantages
When power is available: The light continuously charges its internal emergency battery while allowing normal on/off control via the switch. The lighting function operates as a standard tri-proof light.
When power is cut off: The internal emergency module automatically activates, switching the light to emergency lighting mode to provide continuous illumination, meeting fire protection and emergency evacuation needs.
No false activation: Thanks to the four-wire design and phase consistency between the switch wire and fire-fighting live wire, the emergency mode will not be triggered accidentally when the light switch is turned off during normal power supply.
Safety & Installation Tips
1. All wiring operations must be performed by qualified electricians in accordance with local electrical codes and fire protection regulations.
2. Before wiring, ensure the power supply is cut off to avoid electric shock or equipment damage.
3. Verify the phase consistency of the lighting switch wire and fire-fighting live wire with a multimeter before powering on.
4. Regularly inspect the wiring connections and battery performance to ensure the emergency function works properly when needed.
