Transcript of Signifire Video Fire Detection | British Columbia
Intro to Video Image Detection
● Based on video analytics technology
● Utilized in:● manufacturing● facial recognition● inventory management● product identification
Solution
The most effective fire detection system is the human being, using visual identification of fire or smoke.
Solution
● Signifire uses visual imaging and artificial intelligence (machine vision) to emulate human fire recognition.
● “Trained” with 1000’s of real and false fires.
● Analyzes each frame of 480X640 pixels @15 frames/sec
● Scans 4.5 million datapoints (luma value)/second analyzing the image for signs of combustion 24/7/365.
What is Video Smoke and Fire Detection?
● Uses visible spectrum spatially resolved video images from stationary cameras
● Analyze each frame pixel by pixel using Digital Signal Processing (DSP) high and low pass filters
● Converts 15 frames of pixel data to one normalized pattern
● Pattern is fed to neural network for confirmation
Customized Fire Detection● Detection Algorithms
● Smoke● Flame● Reflected Fire Light● Motion
● All included on camera● Individually enabled and adjusted
● Detect or blocking zones● Sensitivities● Time delay (Alarm verification)● Relay output● On/Off schedules
Targeted DetectionReduce False Alarms
Motion Detection
● Motion detection is a byproduct of analysis● Can be tied to image location and schedule

System ArchitectureVideo Management● SigniFire IP Network cameras● CAT 5 Computer Cable● IP Infrastructure (Switches)● FSM-IP Network Video
Recorder (NVR)● Remote Monitoring Software
SpyderGuardFire Alarm● Dry contacts● Monitor Module● Fire Alarm Panel
SigniFire Server Capabilities
● Processes up to 16 IP camera feeds for smoke or fire
● Can also take any analog camera feeds that have been encoded into an IP stream
ChallengeTypical large volume Detection devices● Spot Smoke/Heat Detectors: ● Beam detectors● Aspirating Systems ● Linear Heat
Challenges● Smoke must interact with detection device● Installation, inspection and maintenance on high ladder, lift or scaffolding
SigniFire can be installed lower than ceiling level and brings detection to the fire.

Challenge
● Conventional detection devices are not suitable for many applications having large volume or high ceilings
● Stratification issues● Sprinkler systems designed for building
protection, require a large fire to activate● First responders require early, “actionable
intelligence” to avoid costly fire damage and injury.
● Cause of fires unknown – can rarely make changes to avoid future incidents
Comparative Testing Objective
●Compare the smoke and fire detection capabilities of various technologies during the developing stage of a fire in a high bay environment. ●Testing was witnessed and documented by Schirmer Engineering●Equipment was designed and installed by fire protection distributors●Test Facility measures ~60 ft by 35 ft with 18 ft ceilings
Results
Detection Technology % activation (% first to Activate)
ASD Level 1 100% (6%)
ASD Level 2 70%
Beam 63%
Ion 55% (6%)
Photo 52%
VID 100% (88%)

Risk Management of Fire
The Risk of Fire is equal to
Probability of a FireX
Loss associated with that Fire
Warehouse Fires - Example
Annual Risk Expense – Probability of Fire X Single Loss Occurrence● 1% chance of fire that requires fire brigade intervention Avg. cost $590,000● 0.25% chance of warehouse fire that causes roof collapse Avg. cost $6,000,000*● Average annual risk expense = (.01 X 590,000 + .0025 X 6,000,000) = $20,900*The Probability of Fires in Warehouses and Storage Premises, Hymes & Flynn, 1992
SigniFire mitigates this risk through very early detection and situational awareness
4 SigniFire Camera System can be installed for less than $20,000!
Combustible Dust
●Combustible dust in a facility can cause a very dangerous condition in suspension●SigniFire can detect dust clouds that resemble smoke●Several of the largest explosion and fire events were attributable to dust
●West Pharmaceutical●Imperial Sugar●Grain Elevators●Coal Dust
Mitigating Nuisance Alarms
● Sensitivities● Blocking or Detection Zones● Delays● Cross Zoning● Schedules● Commissioning Period
Maintenance and Commissioning
● Report generation● NFPA requirements
● Left to Manufacturers● How to commission
● Commissioning report● Ways to test system
● Propane torch● Smoke emitters● Canned smoke● Motion zones● User initiated alarms
