here is a question for you as you probably know in new installations anti freeze is frowned upon it seems possilbe that a fire hose can be attached to the sprinkler system so my question to you is could a dry sprinkler system be attached to a fire hose valve to function as a dry hose valve?
Thank you for your time doing this video. More or less, how many sprinklers could be installed by alarm check valve like that ? for K=16 3/4" sprinklerc type? Thank you in advance
Of course, if you wire multiple detectors on a "zone", they are not gonna know which one tripped it. But if you have a conventional system, and you wire only ONE detector per zone, you get no problems. If you want to reduce wiring, you can use "zone expanders", which are devices that usually communicate via RS485, that will reduce wiring. Another way to wire it, is room-based. Wire zones so all detectors and pull stations in a room is on one zone. It makes it easy for everyone including firemen, to know where something happened, and once you have visual sight with that room, it will be easy to find out what triggered the alarm. I actually prefer conventional systems for 3 reasons: They are easier to troubleshoot, because anything you do will have an instant effect on the system. As you saw, that detector you removed took a whole minute or two before the panel even knew about it. The conventional reacted in a instant, thats because the current flow in the loop ceased and kinda instantly woke up the system. The second reason, is that its easy to integrate non-firealarm-equipment into zones. For example burgular alarm, you might want to interconnect it with a burgular alarm, either to share reporting channel, or to switch between "Remote mode" and "Local mode" depending on if the burgular alarm is armed or not. With that, I mean, when people are present, it might be stupid to send the alarm instantly to the fire department, since the fire could be dealt with locally. It could just be some failed cooking that wasn't even a fire, someone already at the stove that reacted immidiately when that pot started to smoke. So thats why it could be good to have a system that is "local" when people are present, and "remote" (send a instant alarm to fire department) when the burgular system is armed and the building is clearly empty. the third reason is the vendor lockin. A conventional system can accept fire detectors from any other conventional system. You aren't locked in to one manufacturer of detectors. If you choose a adressable system, you need to purchase everything from the manufacturer of your panel. That could be advantageous in some cases, so you know everything works together, but the disadvantage is that you might have a duct detector that is shipped along with a HVAC system nicely integrated, and then you can't use it because you don't have THAT vendor of panel.
whats that test show? i would think the way u test a sprinkler system is to get smoke near a sprinkler head and see if it goes off? im not understanding
ok.if you wanted to rearrange some piping ( usually around ac unit ) where we shut water off and drain pipe? Sprinkler people really need to get their pipes up and out of the way. You trying to tell me there is no shut off anywhere?
We recently had an inspection done by a local company and they said our Gauges needed to be replaced because they were older than 5 years. Can you make a video on how to replace the gauges?
I'm sure you'd have to get an approved company to replace the gauges, you can't just unscrew and swap them out as the entire system has to be approved and certified to avoid shortcuts..
Most gauges used on fire sprinkler systems are installed with a "THREE-WAY GAUGE VALVE" (Google it so you can see an image of it). If your gauges have these valves, you can replace the guages without taking the system "out-of-service". Make sure your new water gauges are listed (approved) for usage on a fire sprinkler system. Use teflon tape on the new gauges if they didn't come pre-taped. Don't use pipe dope.
Fire sprinkler technician here technically you your self are not supposed to change out the gauges but if you wanted to just make sure you close the valve right before the gauge then you can remove it or even safer you can close the main valve on the entire system and drain it just make sure to call it in to the central the watches over the building
Thanks in a million. Great content. Awesome. Very well explained. I couldn't find this explanation--simply put anywhere else. Great teachers are hard to find. Grade: A++💥
Hi im an electrician from NJ just got my license and really want to learm these sytems and wouldlike your input. I sthere a way I can PM you so we can talk? Thanks
in a conventional panel if you had 4 smoke detectors with had leds that had been triggered would they all light up or only one? in an addressable panel does each device have to have a tacked on individual addressable device or does each initiating device incorporate an addressable feature as part of its construction?
Just the one will light up, and each device on an addressable system has a built in end of line. That’s how the panel monitors the troubles and supervisories, the panel is constantly talking to each device in an addressable system and making sure it has the correct voltage.
