  • @paul9511 The first alarm that sounds is the Sprinkler Alarm. That alarms occupants that the sprinkler system has been activated, or there is a opening in a valve head. The second alarm is the Fire Alarm.

  • This is a growing system for fire protection, but still is misunderstood by engineers and installers.A fitter friend of mined installed 2 large systems for Marioff and they could not answer questions regarding the proper installation. Too many conflicting answers. This is a whole new ballgame for fitters...different than anything before it. The AHJ's are completely out their league on this technology.

  • why are there two different alarms ?

  • @dcool96 Oh no, much more than that. It is more around 1700-2000 PSI.And the mist heads haves verrrry small (special) holes, to create mist.

  • @KJ4VGT heat gun... fire extinguishers in commercial operations are often triggered by heat sensors, not "smoke detectors" since other particulate matter in the air can set them off.

  • These systems use nitrogen to pressurize the water. how much nitrogen is released in the protected area and does it pose a suffocation hazard?

  • @paul9511, water mist is more effective in suppressing the fires.

  • What are the advantages over ordinary sprinklers? there was much water on the floor after the test? there was damages? thanks!

  • 1200 PSI?

  • @i8246i water is simply cheaper
