I would also add that as an inspector I always review the data plate to see what the original residual flow was at time of installation, if the results are lower than the system may not operate as intended.
Wow that domestic line is tied to the city feed I get there's a back flow before it's run into the building but old cast and steel aren't doing anyone any favors lol
Does anyone know where I could get certification training . I have a Fire Protection business. I have owned this for over a year but previous owner never got into. Sprinkler systems . I’m in Mississippi
look online NICET training and certification. There is another certification program out there similar to NICET and it becoming widely accepted as the standard just like NICET. Can't remember the name of it, at this very moment.
@@smokeGR20 I understand your point. I write up or document any discrepancies I recognize during supression or detection testing. I'm responsible for both and a 1 man office so I'm more observate on all systems.
That call to the alarm company was fake .. he never hit the tampers and the main drain was below the flow switch he never tripped any horns you could flow that drain all day and the fire department would never respond... wish I had ten accounts just like that lol
Interesting remark. is the water flow alarm supposed to be positioned before the drain? I thought that the inpector test connection was after the flow alarm, not the main drain.
@@cmarname The flow switches are located (in different areas) after the main drain. The main drain test is upstream of any flow switches. Typically, this should not trigger them. The inspectors test is located (usually near the end-of-the-line) at the end of the system. When the inspector's test is performed, a flow switch will detect flow, send a notification, and will trigger the alarm.
It might be a good idea to tell why the main drain test is done, and what percentage drop is acceptable on this type of test.
actuall he does explained it in another small video.

@TH-cam Lover you always do the water supply test regardless if there is a data plate.
@TH-cam Lover Sometimes there isn't a hydraulic nameplate because it isn't required for certain systems.
You need two spares heads for every head installed in the building. You can also disable the horns on the fire panel prior to running water.
Main drain below flow switch so no alarm
@@jaysonmengel2031 if the main drain pipe is located above the water flow switch, it WILL trigger the fire alarm.
No 5 year internal/fdc inspection record?
They didn't have the heads listed anywhere
I dont know when this video was created but it looks like those panel batteries are due for replacement.
Is it required to repeat the test at each floor level (the control valve assembly has also a connection to the drain)?
The main drain test, is a system's test. You cannot perform this test per floor
8" Riser Pipe , with threaded ?
do you have to turn off the fire pump and drain fire hydrants outside, if any, before you do this?
Never put the fire pump out of service
simple answer: NO

In Pennsylvania state

Next time you do a drain test, open the drain valve all the way.
Batteries 11/02/09 Better change them out next time. Good training segment. Thanks.
He did a sprinkler main drain test..nothing to do with batteries..that is done on a fire inspection..so he did a proper test..

Why didn’t you time the static return point after shutting off residual flow
I noticed the same thing

@@paccbutler1826 I was flustered. It makes sense that the water comes upward and never hits the water flow switch so no alarm.
