The RED1: Your Explosion-Proof Flame Detector
The go-to tool when ruggedness, reliability, and response speed are critical.
The go-to tool when ruggedness, reliability, and response speed are critical.
The RED1 is designed to operate in environments where heat, pressure, vibration, and explosive risk are part of daily operation. Its explosion-proof construction and time-tested design allow the detector to remain operational before, during, and after extreme events.
RED1 detectors are built to do one job exceptionally well: detect flames quickly and reliably without becoming the point of failure in a fire protection system.
The RED1 series includes multiple configurations designed to support different system architectures, testing requirements, and legacy infrastructure. Each variant shares the same rugged foundation while addressing specific project needs.
The RED1-ST is the flagship, go-to configuration for most hazardous location applications. Featuring automated self-testing and ultra-fast response, it is designed for facilities that require continuous monitoring with minimal manual intervention.
The RED1-NT is designed for applications where automated self-testing is not desired or not permitted. In some systems, self-test signals may interfere with downstream equipment or trigger unintended responses.
The RED1-E includes additional connection and expansion capabilities, allowing for greater flexibility in system integration. This configuration supports applications that require enhanced communication, additional outputs, or future system upgrades.
The RED1-420 is designed for facilities operating older or legacy control systems that require 4–20 mA signaling. This configuration allows RED1 detectors to integrate cleanly into existing infrastructure without requiring system overhauls.
The RED1-H is engineered for highly specialized applications that demand extremely fast flame detection. Designed for niche use cases where milliseconds are critical, this configuration prioritizes response speed over standard approval sets.
Sierra works directly with distributors to confirm the correct UV IR flame detector configuration, approvals, and system alignment before submittals, ordering, or installation.
The RED1 is used across a wide range of hazardous and heavy industrial applications, including refineries, petrochemical facilities, semiconductor manufacturing, chemical processing plants, and fuel handling operations.
Its versatility allows distributors to deploy RED1 as a general-purpose hazardous location detector while still meeting strict application, approval, and system requirements.
The RED1 series reflects Sierra Safety Technology’s engineering-first approach to flame detection. All of our hazardous location flame detectors are built on proven designs that prioritize simplicity, durability, and long-term performance.
With nearly 40 years in industrial flame detection and zero incidents attributed to product failure, Sierra detectors continue to be specified where reliability and approval matter most.
