Presentation Transcript

  1. NFPA 25 - • The standard for testing Water Based Fire Protections systems • Sprinkler flow switches should be tested on a quarterly basis.

  2. Non-compliant testing These tests have been ignored for a variety of reasons: • Too labor intensive • Difficulty with access • Coordination with alarms/fire services • System downtime • Not able to flow due to chemicals in system Zonecheck eliminates all the excuses…

  3. Zonecheck Testing - Without the need to discharge water!

  4. Operating Principle

  5. Wiring Diagram: • ZC Pump & Flow switch wired to Key-switch

  6. Zonecheck Key-switch

  7. Typical Zonecheck Configuration -

  8. Wiring Diagram: Up to 25 Zonechecks can be wired together

  9. Typical Zonecheck Configuration - (1) Key-switch (25) Zonechecks Connect to Fire control panel

  10. Zonecheck Demo:

  11. Zonecheck Demo:

  12. Zonecheck Models: Zonecheck Retrofit Zonecheck Manifold

  13. Zonecheck Applications: • Schools • Hospitals • Libraries / Museums • Shopping Centers • High-rise Buildings • Hotels • Airports Basically anywhere that ease of testing and system readiness is important

  14. Zonecheck projects:

  15. Zonecheck & LEED Environmentally friendly and LEED certified buildings A conventional Flow Switch test requires approx 100 gallons of water to be flowing either outside, or down the drain Testing quarterly per NFPA would mean 400 gallons annually per flow switch test In a 50 story building, this equals 20,000 gallons of water

  16. Zonecheck & LEED LEED New construction / Major renovation scorecard • Maintenance (LEED v3) Credit 1 Innovation in Design (Possible point = 1) Water use Reduction: Water Reduction 30% 2 points Water Reduction 35% 3 points Water Reduction 40% 4 points

  17. Zonecheck Advantages: • 100% Water Savings • Less System Corrosion • Fire Pumps will not activate • Full System Readiness • Full code Compliance • Simplicity of testing • Labor savings • LEED Points available

  18. Zonecheck Approvals:FM Standard 1043
