following your lack of maintenance logic - what would you rather have an out of date fire extinguisher, probably no where near large enough, also not maintained, that only works if you can get to it, and of course that assumes you are actually in the house at the time - combine that with alarms without batteries or a fully automated, mains water linked sprinkler system that could put out a fire, with minimal water damage, while you were in Costa del Sunshine, or while you slept through your alarms not going off because you used them in the TV remote it's not at all preposterous it's progress
Just the todays anekdote. Asian Customer requested me to put Wylex board, because at their bothers and mums houses when RCD keeps tripping repetedly they can oweride it by pushing trip inwards while lifting it up. SO I have put mine usual standard MK into a car and went to get a stronger build SquareD just in case...
Does such a beast exist?? How would a sprinkler system, once activated, know when the fire was out ??
of course they exist, vaporised water, or in droplet form is far more effective at extinguishing fire that the usual bulk water with very limited surface area as delivered by Sam, and it needs very little of it you ask how does it know when the fire is out ? - if you can accept that the system can work out when there is a fire by using a combination of temperature sensors and rate of heat rise calculations surely you can figure out how the system works out when the fire has been extinguished there's plenty of well proven domestic systems with BRE approval, good to see the Welsh leading the way
Limited. I find that middle Asian customers are far more likely to be requesting brands based on family experiences or asking me to chose safety equipment in order to be able to override safety functions. However it was not ment to stand-out. The request they have made, was more important. I am a foreigner and see no reason to be scared of pointing people by origin as I get sometimes. I do not believe that calling people by origin is bad, even if I Get saved as Slovakian Electrician... I just like the connection between your name and your message for the purpose of joke.
Standard Apollo L2 panel can notice it so do some velux window pannells (I amjust fitting one) texeco alarm panels can reset or just simple relay keeping it on only while smoke alarm is armed. I have connected one of these alarms to honeywell gas interlock valve meaning it cuts gas if alarm is activated for more then 5 minutes
The sprinkler systems I know are, heat breaks glass bubble, water runs out till some one turns off water.
Traditional sprinklers work by a heat sensitive glass ball shattering, water flowing (triggering flow switch and therefor alarm). The water is usually from stored and pressurised vessel, or direct from the mains. Often the pressurised vessel will have two pumps, one to keep pressure topped up during standby times, and one mother fecker pump which attempts to keep pressure up when many ends are open (hoses often share system). These pumps are huge, 250amp TP not being a huge one! Usually also diesel backup pumps. Modern systems use a vessel and pump, but the pipework is dry, being flooded when the fire alarm sounds. The pipework feeds misters. They are meant to control fire with less water, and so cause less damage, less danger and less ground pollution.
Yes, and it is only one sprinkler that activates, the one where the glass ball shatters, or does the release in pressure inside the pipe cause the others to fall out?
domestics use solder link fuses, which triggers the water valve rather than glass balls, glass balls needs to be exposed - domestic heads are usually recessed to the ceiling with a flush cover - and each valve is totally independent - the plumbing is usually just a ring off the mains if the pressure is adequate there's no point triggering every valve within the house if the fire is just within a single room it's a massively growing market, not just in Wales
