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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDual 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.\u003c\/li\u003e\n\u003cli\u003eAdjustable 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.\u003c\/li\u003e\n\u003cli\u003eMultiple 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).\u003c\/li\u003e\n\u003cli\u003eHazardous Location Certification: FM and CSFM approved for Class I, Division 1, Groups B, C, D environments, with IP66 enclosure integrity.\u003c\/li\u003e\n\u003cli\u003eRugged Construction: Powder-coated aluminum or stainless steel options available; MIL-STD-810C compliant for vibration resistance; swivel mount included.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe SS4-A2 provides fast, precise, and durable flame detection for mission-critical industrial fire safety applications.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":49105312579840,"sku":"SS4-A2","price":7519.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/2336.jpg?v=1785544722","url":"https:\/\/alotechparts.com\/products\/ss4-a2-honeywell-uv-flame-detector","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
