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
