The kitchen has two existing exhaust hoods. Both had to be protected by one system, with enough expellant pressure to discharge through both nozzle networks at the same time.

1. 1

   Survey and pre-engineered plans

   An on-site mechanical survey, then drawings using the Ansul R-102 design parameters: appliance coverage, flow numbers, branch lines, actuation tubing and shut-off interlocks.

2. 2

   Plan check

   Plans submitted to the Fire Department plan check and managed through to stamped approval before installation.

3. 3

   Tanks and cartridge

   Two 3-gallon ANSULEX tanks, 6 gallons of agent in total, with a doubler cartridge instead of a single-tank cartridge so both hoods discharge at once.

4. 4

   Piping and nozzles

   Supply piping and discharge nozzles over every cooking appliance, plenum and duct in both hoods.

5. 5

   Balloon witness test

   Test balloons on every nozzle tip, then a manual trip with the fire inspector present. Every balloon inflated, showing an open flow path in both hoods, and the gas shut-off valve and the power interlocks to the kitchen equipment were confirmed.

• Passed on the first attempt

  The Fire Department witness test passed with zero correction items.

• Two hoods, one system

  Both hoods protected by a single 6-gallon Ansul R-102 system.

• One contractor throughout
