detection Fire Risks Firefly Pictures
A hot particle of 470°C can be much more dangerous than a 1000°C spark
• A particle of 470°C with an energy of 40mJ is enough to start a fire or a dust explosion - Note that this is a “black” particle
• A spark has a temperature of about 1000°C • If the energy is higher than 40mJ it is dangerous and must be detected Many sparks have much LESS energy - i.e. too little energy to ignite

Designed to detect ALL potential ignition sources: sparks, glows OR hot black particles Insensitive to daylight – Minimises false alarms
Firefly spark / hot body detectors

Silo
GD • Based on Lead Sulphide Cell (PbS) • Detects from 400°C • 180° view angle • Self-cleaning in most pneumatic transport • Protection of filters, cyclones etc (dust clouds) TD • Based on Lead Sulphide Cell (PbS) • Detects from 250°C • 180° view angle • Self-cleaning in most pneumatic transports • Protection of silos, intermediate storage etc (layers of dust)
ALL FIREFLY DETECTORS ARE INSENSITIVE TO DAYLIGHT

Firefly AB Applications &
detection Fire Risks Firefly Pictures
Firefly Multi-checkpoint™ technology The passing ignition source will be checked 3 times before detection is approved - thus achieving high detection accuracy and minimum risk of false alarms
Firefly AB Applications &
Firefly DualEye™ technology
Two detector cells integrated in one detector - Enables 180° view angle
- One detector will be able to cover the cross-section of a duct
Firefly AB Applications &
Firefly DualEye™ technology
Full 180° view angle will enable better coverage of chutes with large material flows
Other flat lens detectors have a view angle of 70-100°
Firefly AB Applications &
Firefly DualEye™ technology
Firefly detectors with 180 ° view angle Detectors with 70-110° view angle
Closest detector will “see” the glow Detector on opposite side needs to
“see” the glow through the material flow

Self-cleaning effect The air stream in a pneumatic duct or the material flow in a chute will normally keep the lens clean. Keeping half the glass clean is enough for full functionality.
Firefly AB Applications &
Additional air cleaning of detector glasses
In case the material is very sticky and builds up on the detector glass, there are different proven methods of keeping the glass clean
Firefly AB Applications &
Air cooling of the detector glasses
CAR - Air cooling equipment for the detectors
If the temperature exceeds 60°C the
detectors must be equipped with cooling

Firefly AB Applications &
Firefly Protecting baffles
If hard pieces (stones, metal etc) occur in the material flow or if the
material is very abrasive, protecting baffles can be used to protect the
glass

OAD • 2 Channel UV/IR - Flame detector • High immunity to false alarms • Quick reaction time • Used in open areas
OPD • 5 Channel IR (IR5) – Flame detector • High immunity to false alarms • Quick reaction time • Less sensitive to dirty applications • Used in open areas ALL FIREFLY DETECTORS ARE INSENSITIVE TO DAYLIGHT
Firefly Flame detectors
Firefly AB Applications &
Firefly – OAD detector
• Used for quick and early detection of flames in open areas
• Two channel – UV/IR technology - Efficient flame detection - Patented Fire Event Analysis (FEA™) discrimination technology - Minimises false release
• Constant Self-testing
- Type and sensitivity of the detector
- Temperature in electronics

Firefly – OPD Detector
• Used for quick and early detection of flames in open areas

- Used in process ducts and chutes
• Unique design - spraying from different directions into a chute or duct
• Full cone spray nozzles
• Minimum three water nozzles and solenoid valves per zone
• Quick-connection and flexible hose - Easy to test the system without releasing water into the process

or in open areas
• Smooth cooling effect – less risk of thermal shock
• Minimal water usage
Firefly water mist
Firefly AB Applications &
Silo
The small water droplets will evaporate into steam
• Cooling - when turning into vapor, the water mist absorbs more heat from the fire than any other extinguishing agent (>2 MJ/kg) • Inerting - when evaporating, the water particles expand by 1700 times, thereby displacing the oxygen • Heat absorption - The water mist will “block” the heat transfer from the fire

Control unit type CUE
Master unit type MUE
• Control unit type CUE will be located close to the process section • Shorter cables from the CUE-unit to detection / extinguishing equipment • Easier installation • Individual function and battery backup from each panel means higher safety • One master unit MUE can be used to collect data from up to 30 CUE-units
