Product catalog summary
Overview: The 20/20M Mini Series Flame Detectors are compact, high-performance devices designed for both indoor and outdoor applications. They feature IR3 and UV/IR detection technologies, offering high immunity to false alarms and resistance to harsh environments. The series includes models with intrinsically safe (I.S.) approvals.
Specifications: The detectors are housed in rugged stainless steel enclosures, weighing 2.5 lbs (1.2 kg) and are less than 50% the size of standard explosion-proof detectors. They operate on low power and are suitable for areas where Ex hazardous area approvals are not required.
Models:
  • 20/20MI-1: Triple IR (IR3) detector with high false alarm immunity, available in general-purpose or intrinsically safe formats.
  • 20/20MI-3: Similar to the MI-1 but with lower sensitivity, ideal for small areas requiring fast detection.
  • 20/20ML: UV/IR detector for detecting various types of fires, with a special logic circuit to prevent false alarms from solar radiation.
Main Features: The detectors offer a large field of view (100°), low power consumption, high-speed response, and compatibility with RS-485 Modbus. They include automatic and manual built-in tests and are user-programmable via software.
Applications: The detectors are suitable for a wide range of applications including aircraft hangars, heavy-duty vehicles, office and atrium areas, waste handling, unmanned gas stations, and marine vessel engine rooms. They are also used in automotive parts manufacturing, chemical industries, nuclear power plants, and more.
Performance and Approvals: The detectors have a typical response time of 5 seconds, with adjustable time delays up to 30 seconds. They are approved by various standards including ATEX, FM, VdS, and others, ensuring reliability and safety in hazardous environments.
Accessories: Available accessories include rain covers, laser aimers, air shields, long-range fire simulators, and tilt mounts to enhance installation and operational efficiency.

M “Mini” FLAME DETECTOR Series Main Applications Aircraft Hangars Leaking fuel is the main danger in aircraft hangars, easily causing fires and potentially harming personnel, equipment and facilities. The SharpEye Mini Optical Flame Detectors allow military and commercial requirements for reliable fire protection to be met. Due to the 100º cone of vision, there is wider coverage of the protected area. The area around the walls of the hangar where the detectors are mounted does not require EX proof so the 20/20MI non EX is suitable. Off Road Heavy Duty Vehicle Large mining vehicles are vulnerable...

SharpEye BO/BUM "MINI" FLAME DETECTOR SERIES Main Applications Modern automobile fueling areas are designed with high-speed self-service pumps, enabling customers to fuel their vehicles fast, but more susceptible to fire. Risks can include customers forgetting to return the nozzle, burning cigarettes, running engines, sparks and other heat sources, whereby flammable liquids can be easily ignited. The 20/20ML was designed to prevent any such hazards from spreading, combining UV and IR sensors to detect hydrocarbon-based fuel and gas fires, hydroxyl and hydrogen fires, as well as metal and inorganic...
