Information About SS4-A2
The SS4-A2 is a flame detector built to detect hydrocarbon-based fires with rapid response and reliability in extreme environments. It uses dual-spectrum detection—ultraviolet and wide-band infrared—to improve detection accuracy and reduce false alarms. Its sensitivity settings can be tuned based on the distance and application, ensuring flexibility in coverage, whether for smaller protected spaces or extended outdoor zones. The device includes selectable latching or non-latching alarm relays, a fault relay, and a verify relay with programmable delay to confirm the presence of sustained flames.
Key Features:
- Dual Spectrum Detection: Utilizes UV (185–260 nm) and IR (0.7–3.5 µm) bands for flame detection, ensuring reliable hydrocarbon fire recognition while minimizing false alarms.
- Adjustable Sensitivity and Response Time: Detects a 1 sq. ft. gasoline flame at up to 18 meters in 2–5 seconds; configurable for closer ranges as needed.
- Multiple Relay Outputs: Includes fire alarm, fault, and verify relays with both NO and NC contacts, supporting latching/non-latching fire output and programmable verify delay (0–30 seconds).
- Hazardous Location Certification: FM and CSFM approved for Class I, Division 1, Groups B, C, D environments, with IP66 enclosure integrity.
- Rugged Construction: Powder-coated aluminum or stainless steel options available; MIL-STD-810C compliant for vibration resistance; swivel mount included.
The SS4-A2 provides fast, precise, and durable flame detection for mission-critical industrial fire safety applications.
