  1. Product overview FMNA Automatic Fire Suppression System

  2. Overview • System overview: • - Top level overview • - Component overview • - Assembly / Mounting options • Benefits: • - Proven technology • - Worldwide applications • Certifications • UL update • - SBF128 • - Performance of system • - Environmental implications • False activations / clean-up • - Next Steps / Q&A

  3. System Overview Top Level Stainless steel routing LOP Detection Tube Detector Piston Accumulator

  4. System Overview Detection Loss Of Pressure (LOP) - Strategically routed throughout the protected compartment. - Bursts or melts at ~375º F opening release valve - Simple pneumatic activation, does not require electricity - Eliminates false activations due to electrical issues - Manual activation option Other Options: - Spot thermal sensors - Linear thermal wire - Manual push button activation - Methane detection

  5. System Overview Piston Accumulator - Patented design - 4L (small bus), 6.5L & 7.5L (large bus) systems. Option to gang PA’s together for larger vehicles. - Stores / releases H2O mix - System charged to ~950 PSI and provided continuous flow for 40-70 seconds. - Mounts and works in any orientation, no system orientation concerns (rollover, etc)

  6. System Overview Nozzles - Patented spray nozzles deliver 2000 atomized droplets (80 micron) per 1mm droplet - Spray is a 90° coned shape pattern - Water mist flashes to steam and can be indirect to the fire - Nozzle covers to prevent contamination

  7. System Overview Assembly / Mounting Options - Piston accumulator can mount in any orientation allowing for more mounting options than powder systems. - 6 inch diameter allows for tight space clams. - Alarm panel monitors system pressures and controls engine shutdown. - Optional fire button allows for manual deploy.

  8. Benefits Proven Technology • - 70,000+ systems installed worldwide • - Fogmaker is the leading fire suppression supplier in the European and Australian bus market. Fogmaker is the preferred system for Mercedes & Volvo in Europe. • - UK overview: Total fleet of ~600 with Fogmaker, 33 known incidents over 4 years with all being suppressed without issue and minimal damage. • Australia, we have installed well over 1000+ Government Buses with Fogmaker and we have to date had approximately a dozen thermal events with buses fitted with the System. In all cases, the system has detected & suppressed the fires with little or no damage with exception to “what” caused the initial fire (ie cracked fuel rail, electrical arcing, broken lines / hoses, debris etc.) • - Over 1000 buses in US and Canada are now using Fogmaker – UL Listing was requested by some larger customers. • CNG application in Tempe with NFI, very happy to date and positive result on incident

  9. Benefits UL Listing update • Officially listed UL product as captured under listing for Fogmaker NA • Listing is per UL Subject 1384 • Testing consists of system level detection / suppression testing as well as multiple component level tests (over 100 total tests in all) • Only system UL approved for ‘self-contained automatic extinguisher units’ as other approvals relate to total flooding and do not cover complete automatic detection systems • Listing can be found at www.UL.com

  10. Benefits SBF128 • -Testing method was that of SBF128 • (Full-scale extinguishing trials of water mist in a bus fire) • - SBF128 is a Swedish test protocol executed by SP (Science Partners) and tied to the Insurance Institute • - Overview of the test • 20 min preheat of bus (15 @ idle, 5 with throttle) • 7 pounds of woodchips presoaked for 24 hours with a diesel / oil mixture placed throughout engine • Cotton rags presoaked with above mixture also placed throughout • 1.5 liters of Diesel / oil sprayed throughout • Ignite engine compartment with torch • Close and burn for 20 seconds • Manual activation of the fire suppression system • Continue to run engine / fan at idle speed

  11. SBF 128 Test protocol

  12. Benefits Performance - Attacks all 3 elements of the fire triangle: - Heat: Water mist cooling effect. - Fuel: AFFF (Foam) blankets the fuel - Oxygen: Steam chokes out the oxygen - Longer cooling & suppressing time - 40-70 seconds continuous - Re-flash prevention -Hot surfaces are cooled below flash temps -Any remaining fuel is covered by the AFFF (Foam)

  13. Benefits Environmental - No hazmat required - Fast easy clean-up - Not harmful to people - Not harmful to equipment - Water mist

  14. Benefits False Activations / Clean-up - LOP requires no electricity or operator involvement thus reducing false activations due to electrical shorts & operator error. - Clean-up is fast and only requires pressure washing of protected area. - PA & detector can be recharged in vehicle or exchanged for an in-stock replacement. - The system can be recharged in under 1 hour by trained personnel on site.
