The 20/20M Mini Series Flame Detectors are high performance, unique IR3 and UV/IR flame detectors featuring lower cost, lower power, and more compact structures. The mini detectors are highly resistant to harsh environments, immune to false alarms and are designed for use in OUTDOOR or INDOOR applications. The IR3 model is also available as intrinsically safe (I.S.) approved format.

The detectors’ small size, low cost and low power allow easy installation in small or congested areas where Ex hazardous area approvals are not a prime requirement. Both models are packaged in rugged, stainless steel enclosures that are less than 50% of the size of our standard explosion-proof detectors and weigh only 2.5 lbs (1.2 kg).

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 to catastrophic fires particularly in engine compartments, as have been experienced in recent times. It is vitally important that fire protection capabilities are up to date with the latest technologies. The high-speed short-range version of 20/20MI-3 (up to 10 ft) is ideal to protect the large engine compartment of the vehicles, and is used in coal, metals and minerals mining.

Office Areas and Atrium Areas

While an atrium space has many merits, there is a danger that it could become a building’s weakness in fire protection, potentially allowing a fire to rapidly spread. The 20/20M Mini’s fast detection identifies a fire in its earliest stages, facilitating suppression. Modern hospitals feature large atria and open space areas. Due to the difficulty or impossibility of moving patients in an emergency, hospitals must follow a defend and protect in place policy rather than conventional evacuation. Hospital fire protection and evacuation requirements are therefore highly complex and the SharpEye Mini Optical Flame Detector is responsible for meeting them with its low cost and supreme reliability.

Waste Handling

Recycling reduces the quantities of materials deposited in the world’s landfill sites and saves natural resources, but must be coupled with appropriate fire safety measures. Unique risks are posed at recycling and waste handling operations, such as disposal and recycling of combustible materials. The 20/20M Mini Flame Detector is a successful choice to solve these issues, and has the additional benefit of low cost and low energy requirement. Recently, a recycling and waste handling plant in the Netherlands installed 84 SharpEye Optical Flame Detectors model 20/20MI to detect fire in the various deluge zones.

Unmanned Gas Stations

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 fires.

Marine Vessels Engine Rooms

The engine room on a marine vessel is where the machinery of a ship is located. Fuel or oil spills from the machinery are a fire risk factor, alongside petrochemicals used for the cleaning and servicing of the machinery. The fuel, oil and petrochemicals are flammable and can easily ignite. Therefore, Spectrex Optical Flame Detectors are required to identify a fire and subsequently activate the installed fire suppression system. Spectrex 20/20M Mini Optical Flame Detectors are suitable for both commercial and military vessels.

Alongside the above-mentioned applications, the 20/20M Mini Series is specifically suited to the following applications:

  • Automotive parts manufacturing
  • Burners, boilers, and heaters
  • Car parking towers and garages
  • Chemical industry
  • Nuclear power plants
  • Power generation – pumps, generators and unmanned stations
  • Recreational and sports arenas (facilities)
  • Storage areas
