Victaulic FireLock NXT™ Series 769 Preaction Valve – Placing System into Service video instructs the user to start by confirming the system is drained & depressurized and to close the systems main pipe drain valve. At conclusion, the video guide instructs if there are no leaks to then record the system air pressure & water supply pressure & observe pressures for 24 hrs for degradation.
Tyco Deluge Valve DV5 Video explain about How to Tyco Deluge Valve model DV 5 in electric mode. More information about Tyco Dv5 Deluge Valve Flood systems are commonly used in fire installations with special hazards, where it is sought to apply the discharge of water to a complete area of protection, by the use of nozzles. The function of deluge valves is to control the flow of water in deluge or preaction systems. The DV-5 model is characterized by being a diaphragm valve, so it depends on the water pressure in the chamber to keep the diaphragm closed against the pressure of the water supply. A signal emitted by a complementary fire detection system in the same sector as the sprinklers will allow opening of the diaphragm and will supply the flow of water in the sprinkler network. T...
A single interlock viking electric pneumatic double interlocked preaction systems utilize a deluge if the detection system (alone) operates due to fire, damage, hi fog pre action are used protect areas where there is risk of false discharge or home fire protection suppression can you explain 'dry action' system? As have probably surmised, numerous 'types' water based sprinkler feb 27, 2016. Second, individual sprinkler heads release to let water flow onto the fire a system is an active protection method, consisting of supply system, this delay in suppression results larger prior control, pre action systems are hybrids wet, dry, and deluge systems, depending can be considered single interlock double on intentions coverage. Pre action fire sprinkler systems from associated protection contain...
Got Corrosion? We have the SOLUTIONS!!!! Internal Corrosion MYTHS: Some municipal water supplies are full of unexplainable corrosion causing mirco-organisms. Steel pipe is not as good as it used to be. Something was introduced to the pipe during installation that is now causing corrosion. The remedy is to replace all pip and add expensive chemicals. Internal Corrosion TRUTHS: Steel rusts when exposed to moist oxygen. Trapping air and introducing fresh oxygenated water is the real problem Effective mitigation requires accurate analyis . Common Knowledge about internal corrosion is erroneous. Western States Fire Protection KNOWS the truth and HAS THE SOLUTION!!!

This video shows three dry system sprinkler risers with a pre-action setup to activate a releasing solenoid when a heat detector in the protected area is activated. This video shows that the fire alarm panel is activating the solenoid valves correctly.
I'm explaining how fire alarm systems work for new technicians or other employees who deal with these systems. This is my 18th video in a string of many Khan Academy-styled lessons. This video introduces how dry sprinkler systems work and how they are monitored by the fire alarm panel.
