HSJ-RJ2601Measuring Pyrolytic Particle Electrical Fire Monitoring Detector / Energy Storage Composite Fire Detector / Pyrolytic Particle Sensor

I. Overview:

This product is a measuring pyrolytic particle electrical fire monitoring detector, primarily used to monitor changes in pyrolytic particles within the protected area. Its working principle is as follows: materials such as cables and plastics decompose under heat to release particles and gases, with these particles being the smallest material components that can exist in a free state. Regardless of the cause, electrical fires in their early stages manifest as object heating, particle and gas release, and the production of odors. The main heat sources in electrical cabinets during electrical faults are cables, load switches, and protectors, with the particles decomposed by heat in electrical cabinets mainly being salt particles and gas molecules. The HSJ-RJ2601 Measuring Pyrolytic Particle Electrical Fire Monitoring Detector can monitor particles (with diameters ranging from 1nm to 10nm) and gases produced by the overheating decomposition of electrical equipment such as polyvinyl chloride (PVC) insulated cables, acrylonitrile-butadiene-styrene copolymer (ABS), epoxy fiberglass laminated boards, various types of batteries, circuit breakers, and load switches. It provides real-time alerts before visible smoke is generated, detects insulator heating, and enables ultra-early monitoring of electrical fires to prevent hazards before they occur.

II. Technical Features:

The Measuring Pyrolytic Particle Electrical Fire Monitoring Detector can be used independently or connected to an upper computer via a switch output or RS port. When alarm conditions are met, it provides audible and visual alerts and feeds the detection results back to the upper computer. This product can communicate in real time with the upper computer via RS, relaying monitored pyrolytic particle data. The detector integrates three sensing technologies and accurately monitors seven types of parameters. Through a dynamic weighting algorithm for multiple parameters, it effectively avoids false alarms caused by various interference factors.
