Easy Guide: FIREYE 95DSS3-1CEX Flame Detector
1. Product Overview
FIREYE 95DSS3-1CEX is a dual-spectrum explosion-proof flame detector designed for industrial fire safety. Acting like a “24/7 fire watcher” with sharp eyes, it uses both ultraviolet (UV) and infrared (IR) sensors to detect flame signals from fuels like natural gas, diesel, and gasoline. It quickly distinguishes real fires from false alarms (such as sunlight or welding sparks) and sends alerts to the safety system to trigger actions like shutting down equipment or activating sprinklers.
Its core working principle is simple: When a fire breaks out, it emits unique UV and IR light. The detector’s dual sensors capture these signals at the same time, and its built-in smart chip verifies if it’s a real fire (not a false trigger). If confirmed, it sends a 4-20mA or relay signal to the control panel within 50 milliseconds. For example, in an oil storage tank farm, this detector can spot a small diesel leak fire 30 meters away and trigger an alarm before the fire spreads.
Key advantages that make it reliable in tough industrial environments:
-
Double Protection Against False Alarms: Dual UV/IR detection ensures it ignores non-fire light sources (e.g., incandescent lamps, lightning). The false alarm rate is less than 1 in 10,000 hours—far lower than single-spectrum detectors.
-
Explosion-Proof Safety: Certified with Ex d IIC T6 Ga explosion-proof grade, it can work safely in flammable and explosive areas like chemical plants, oil refineries, and gas stations without risking sparks.
-
Wide Detection Range: It can monitor an area of up to 113 square meters (when mounted 3 meters high) with a 120° viewing angle—no blind spots for most industrial sites.
-
Low Maintenance Trouble-Free: The sensor has a 5-year service life, and the detector is IP66 waterproof and dustproof. It works normally even in heavy rain, high dust, or -40℃ cold environments.
Practical example: In a chemical reactor workshop, the 95DSS3-1CEX detector is installed above 6 reactors. When a reactor’s seal fails and causes a gas leak fire, the detector alarms in 40ms. The safety system then shuts off the gas supply and activates the local fire extinguisher, putting out the fire in 20 seconds—avoiding a major explosion.

3. System Integration Guide
FIREYE 95DSS3-1CEX is a key part of industrial fire safety systems. Integrating it only needs simple matching with safety controllers, alarms, and power supplies—no complex programming. Here’s the step-by-step guide with safety tips:
3.1 Integration Steps (with Safety Tips)
-
Site Preparation: Choose a mounting position with no obstacles (e.g., pipes, equipment) blocking the viewing angle. Ensure it’s 1-5 meters above the potential fire source (e.g., near a fuel tank’s valve).
-
Secure Installation: Fix the detector on the bracket with stainless steel screws. Tighten the explosion-proof shell’s bolts to ensure no gas leaks—this is critical for hazardous areas.
-
Wiring Connections: Connect 12-24V DC power to the “Power” terminal (note positive + and negative -).
-
Link the “Signal Output” terminal to the fire safety controller (4-20mA for continuous monitoring, relay for direct alarm triggers).
-
Use explosion-proof cables and sealing glands for wiring in hazardous areas—prevent flammable gas from entering the detector.
-
Simple Configuration: No software needed! Use the detector’s built-in DIP switches to set: Alarm delay (0-10 seconds, usually set to 1 second to avoid instant false triggers).
-
Output type (4-20mA or relay, based on your safety system’s requirement).
-
Test to Ensure Reliability: Use FIREYE’s standard test lamp (simulates fire UV/IR signals) to point at the detector— it should alarm within 50ms.
-
Test with a welding torch (10 meters away) — it should not alarm (proves anti-false alarm function).
-
Check if the safety system (e.g., sprinklers, shutdown valves) responds correctly to the detector’s signal.
3.2 Daily Maintenance Tips
-
Daily Check: Look at the status LED—steady green = normal, flashing red = alarm, steady red = fault (e.g., power loss).
-
Monthly Cleaning: Wipe the detector’s lens with a soft cloth (avoid scratching) to remove dust or oil—dirty lenses reduce detection sensitivity.
-
Quarterly Test: Use the test lamp to verify alarm function. Check wiring terminals for looseness (vibration can cause poor connections).
-
Annual Calibration: Hire FIREYE service personnel to calibrate the sensors—ensures detection accuracy meets standards.
