that's a bit unlucky, I jumped the gun & bought the book online before I finished watching this very informative video. & paid a lot more than the Amazon link you shared. Great content as always guys
Hi Joe, is this still the most up to date book, or is there a newer one out ?? Thanks Chris
You didn't mention that we now have different regs in Scotland and that ALL properties need to have interlinked alarms fitted. Fortunately Fire Angel cover the retrofitting with the battery alarms they produce otherwise it would cost home owners a small fortune. As it is with units cost around £40 each it isn't cheap. The main problem with the Scottish regs is that they stipulate where the basic alarms should go with no accounting for the property use or ignition source. E.G there is no requirement to install an alarm in a utility room that almost certainly will contain a washing machine, tumble drier and freezer, all of which have been major ignition sources. But you have to put one in a circulation space with no ignition source regardless of having each room off that space covered by separate alarms. My wife is deaf in one ear and doesn't hear the alarm clock, so I have installed an alarm in the bedroom, also there are USB charges and various other potential ignition sources.
Great information, I didn't know that about Scotland. Thanks for commenting!
Also acceptable to fit wireless smoke and heat alarms with 10 year lithium ion battery to comply with the Scottish legislation. All the best, Pete 👍
@@peterc3228 That is the only practical solution for most retrofits. I certainly wasn't about to cut up floor boards or worse still damage artexed ceilings to fit hardwired versions. That would have cost another £1000 for what is a knee jerk reaction by the Scottish Government based on the Grenville incident. Whilst I agree alarms save lives and I have always had them, what saves more lives is proper maintenance and awareness of potential ignition sources.
I've not had good experience with Fireangel detectors. Fun fact: If they are not mounted onto their mounting plates, then the detectors won't activate when the test button is hit. You can try this prior to installation.
I've found that if the mounting plate is not screwed to the ceiling via the middle screw mount, then the weight of the detector on the mounting plate will cause it to sag a little, and then you have a discontinuity that leads to the detector failing.
Nothing wrong with the electrical wiring, and not an immediately apparent problem, but a little sagging (a few mm) over the space of a couple of weeks will cause the test function to fail (even if the mains indicator is illuminated). Solution is to remount the plate using the central screw hole.
i fitted one of those make smoke detectors in my own house once, it caught fire and set itself off! gone back to aico, best make to use.
That’s one way of drumming up business I suppose.
Hm, was it an internal fault on the smoke?
@@efixx the circuit board released its magic smoke, was a basic battery one that i put up as a stopgap while i wired mains one.
Interesting...
Brilliant in-depth guide to the fire alarms, thanks for a great video as per usual. 👍🏼
Our pleasure, thanks for commenting! 😊
The inner nerd in me enjoys Joes instructive videos, well done mate
Cheers matey! 😊
Great video Joe, thankyou 👍
Thanks, my older standalone type detector is EOL so I'm looking to replace, this is a useful guide of what I could do.
Glad it was helpful!
Great video this is what i like can't complain about this one👍
Good to know, thanks for commenting!
Thanks Joe Very good video 👍🏻👍🏻
Thanks very much! 😊
No mention of the need for a CO detector in any relevant installation?
In my home town I see! Great video as always guys!
Ah nice! Glad you enjoyed it. 😊
Things have really moved on since I was a fire alarm sales design engineer for major commercial sites such as office blocks and shopping centres etc. Domestic is now better than some of them used to be, thank goodness.Our company, a multinational, pulled out of fire defence because of the risk after a hotel and brewery burnt down with systems to correct specs at the time.
Wow, that's really interesting, must have been a combination of circumstances that led to that happening, major decision for a big business. 🤔
Great video mate just wondering if you have a video regarding commercial regs
Cheers Joe.
The interconnecting cable between smoke /heat alarms is not mains voltage. It's a low voltage trigger (9 volt ) . It's 9 volt because it has to work when the mains power is off and it's working from the integral battery .
thanks it does make sense.
Correct
Great comment, thanks for the info!
My understanding is the voltage is low, but it's not isolated from the mains (it's normally referenced to the neutral), so it still has to be treated as a "live conductor".
In Wales and England. As an electrician do we have to certify, a like for like smoke alarm replacement, i.e. due to an out of date smoke alarm.
That was really good that. At last, the regulations are changing for domestic installation.
Nice information Joe, thank you. I had some experience of Hochiki detectors, they used 24v power and I didn't know we have detectors which use mains power. interesting!
Thanks Sajad, more of a domestic situation for mains powered. Thanks for commenting!
You are referring to Commercial Fire Alarm Detection systems, that have a separate control panel with 24v Sounders/Beacons and Smoke/Heat detectors. Domestic was initially 12v stand alone detector/alarm combined with no control panel, then progressed to mains with a 12v back up battery, also stand alone, no control panel.
Great video as always guys! Where does the UK stand on using ‘smart’ smoke detectors? I take it as a home owner your able to install one either with or without mains and do t technically need a link between multiple devices? Cheers - Dan
as an alarm collector when i get chance ill be installing a full conventional fire alarm system in are three bedroom house, some people may think its a bit over the top but if you think as all the detectors are mains operated and have a back up they are much better. and also callpoints will be in use so it will be much more easy to sound the alarm
Wow, send us pics on social media, sounds amazing!
@@efixx will do!
I've never yet come across a fire that's been scared out of a building by a fire alarm. My friend wouldn't bother with alarms. He'd simply fit sprinklers everywhere. Minimal maintenance and fire prevention - as long as you don't turn the water off during your winter holiday !
This is one of the few areas where we in the USA are ahead of the UK. Smoke detectors are required in each and every bedroom. At times I'm lucky that I'm woken up by my alarm clock, so I wouldn't want to rely on being woken up by an alarm outside my closed bedroom door. I will say that when all my interconnected alarms go off it does make quite a racket.
That's interesting, similar would be required in some circumstances but you're right maybe we need to have a look at how it's done over the pond...
Probably due to your proliferation for timber frame buildings and natural gas utilities?
4:30 strange about putting smoke alarms in attics (lofts). Here in the US they say not to install them there in unfinished areas due to dirt/dust and false alarms. You can use heat detectors up there, but here in the south were attic temps can climb into the 150F (65C) range when its 115F (46C) outside you have to make sure you use pretty high value heat detectors.
Aico recommend not using the aerosols for testing as they leave a residue in the detector. They say just to use the test button. The Aico 3000 series also have a brilliant download feature from each detector with lots of information so sorry I'll be sticking with Aico. The standards change so much it's difficult to keep track what is current, Scotland is different as well. Thanks Joe
It's interesting to hear different people's take on things. Thanks for commenting!
Well said Mark. I've installed many Aico 3000 systems and the are expensive but trustworthy. Been to a few FA installs after 6 months the RF signal seems to be problematic on some. Scotland has the new tolerable standard act of 2019 which is live at the end of Jan. It's making every property safer, as long as the customers are avoiding the cowboys. It's the PV FIT gold rush all over again for Clint Eastwood and his mates.
I have Nest fire alarms. They communicate with each other. Verbally tell me exactly where the fire is. They also have path lighting built in.
Weekly checks and reports with an app.
WHATTTT??? No fake acting this time? Great, informative video!!! 5*
😂 Only 100% genuine acting in this video!
I have a question maybe someone can answer with clarity on how its been reached.
If a customer has a wired system and its out of date and they wish to replace it for a smart smoke like one from SimpliSafe is that allowed or do you have to have 4 alarms for example on a two story 2 downstairs and 2 upstairs one smart one dum
Hope this makes sense
Except in Scotland. I believe that if you are replacing a detector there would be no need to redesign the whole property. You would need to test and commission the replacement. Noting as a replacement, recommending that the installation is brought up to current standard .. and recommending risk assessment if none available.
Good question, we'll do some research.
Good luck getting fire angle wireless interconnect battery units been trying to get them for months now even tried fire angle direct thay don't know when thayr due In stock first class units easy to install etc but with most things in the building trade no production either due to covid or brexit plenty of work but no materials what's happening fire angle?? 🤔🤔
Just done a quick check and CEF appear to have a load as well as our local Screwfix. 🤔
Thanks I'll call my local cef & screwfix now thanks guy's 👍
0:33 - do show us how you get under those stairs !
It involves the limbo!
employers require installing Aico multi sensors on EICRs if there is equipment in the attic, heat/co2 in kitchen and where ever there is a boiler and updatedd to LD2 D1, brownie points for thumb nail
Ha! Glad you clocked the thumbnail. Cheers!
Surely you wouldn't put a co2 detector in a kitchen with no gas or solid fuel appliances?
@@monikaw1179 combined heat/co2, chances are you have a gas boiler, gas oven or both
@@N1cholls93 Many kitchens are all electric, and the boiler isn't necessarily in the kitchen. My own home is like that, for example. I have a co2 detector in the room where the boiler is, interlinked to the smokes. Also battery co2 detectors in the bedrooms due to my paranoia. I don't have one in the kitchen as it would be pointless.
@@N1cholls93 CO, not CO2
Here's my thoughts and questions. The 11k and 25k electricians from The electrical community and The electricians talk group will tell you never to use Fireangel as they are absolute S***E.
Aico is the way to go👍
I don't see a question but thanks for commenting! 👍
Yeah Aico are good , but according to the trainer who did a training session when I worked for a housing association on installing their products they don't get any faulty items . I said bullsh*t any manufacturer is always going to get some faults especially if you sell hundreds of thousands of devices . Also we had faulty ones which we had to replace when they were going off randomly.
As a designer and specifier I would always specify AICO. This is likely to be a paid promotion for fire angel and not a unbiased recommendation.
I use Kidde Firex, always been reliable for me. I think Aico might have the edge with the cable connection side of things though.
Haha, very nice thumbnail
Thanks! 😊
Interesting Idea of your government that you need all this stuff for be save inside a house but why do you not have regulations about *the place* to install the CU (and fire alarm control) e.g. in height of 1m till 1.8m and near the entrance door - so that the normal UK people can find it easy if do you have an electrical or fire alarm problem. Or the fire/police man or neighbor after a call?
The second is that all this stuff should be checked and renewed same the CU all x years. So how paid all this costs for install and checking and reinstall all x years? All people must have a fire insurance same the health insurance how pay all this costs? What happened if the system works incorrectly if have a fire e.g. Grenfell Tower? What if check-list tested but the tradesmen would do a wrong install or the home owner creates a new room with hazardous materials between the checks and renewed installs? I think about this things do you not speak but I think too this points are not figured out in the book.
In Germany we use single alarm with battery (change yearly) or 10-year-longlife batteries for private houses only. The half-yearly test do every homeowner alone. In skyscrapers mostly worked an extra company, payed from landlord or owner. All components are compatible together and costs new around 20 till 30€/piece.
Companies and firm houses need a central 240V point, extra back-up batteries, and central alarm display. But I see first radio connection between them for older properties (where one interconnected system over cable impossible e.g. remote areas). This should be tested every two years or after a fault or use it. All products are selled over 10 years with a theoretical lifetime warranty.
Hm, maybe we've got something to learn from our cousins on the continent!
Still no real regs about the correct place on a ceiling etc >Distance from walls .ONLY must be to manufactures specs. This needs to change .
I wish the alarm went off before I carbonise my toast!
Yeah I’ll just stick with my Nest Protects! They all talk to each other and plus do CO2 and do self test of speaker mic and wifi itself
Thanks for commenting!
Nest protect detect CO (carbon monoxide) not CO2 (cardon dioxide found in carbonated drinks). Also if you have the nest thermostat it will also switch off your boiler with it detects carbon monoxide. I wish they would make an heat detector, so I can continue my system but it will look like I will be going over to Aico
@@charliechan22 lol yes now you’ve said it I’ve just noticed what I put yeah I’ve got the thermostat too, but it looks like Google has killed the company as they are not really doing much at the mo with no real new devices on the pipeline
In Scotland, under 2022 Regs - Note that the Nest Protect System will not meet the standard. This is because they do not meet the requirements for a heat alarm under the relevant British Standard. British Standard (BS 5839-6:2019) states that only heat alarms should be installed in kitchens.
@@agpe829 which is a shame as all the nest protects have the heat sensor built into it already, they just need to disable the smoke side in the kitchen ie when you place it in a kitchen for it to disable the other sensors and maybe give a warning that it’s in heat detect mode only during tests and for it to display differently to the other protects in the app to reflect that
Great video Joe
Very interesting and informative.
But I don’t think it should be a sparks job to install fire alarm systems, same as I don’t think we should be installing video door bells like the ring .
There are enough specialist companies out there who can do that job so we should leave it to them. As for video door bells any idiot can install them they are so so simple to install so why are electricians installing them? Don’t they have better thing to be getting on with. Great video as always 👍👍👍❤️
Well it's good to have a diverse set of skills to offer customers I guess. 😊
Ring video doorbells require a 24v transformer, thats why most folk get an electrician.
It's expensive enough being a spark, no way I'm buying fire alarm testing kit as well. Push the button and see if it beeps. 🤣
Only use Aico 🤣
Just don't use ionisation
Ha fire Angel where every expense is spared
Risk assessment. Don’t fit fireangel there shite!
Stopped watching when seen fire angel
Happy to instal, but I won’t be responsible for system design. Sorry but my view of the BS for domestic fire detection is in need of trashing and starting over.
Interesting, thanks for commenting!
Happy to take the money, but not willing to do the work or make sure it's safe for the property or the intended occupant. Sounds about right for a house basher! Your attitude the reason legislation is written.
@@sandymcnair5298 hi Sandy - just to clarify - I won’t be doing design as I no longer feel I can perform the function. So, as another has already suggested, I will leave fire safety system design and compliance to a competent person… Please note - your gas lighting abuse is not appreciated by me. Hopefully being concerned with mental health and well being is something you (and others on this channel and in the industry) have a care for.
@@davidw460W Two different posts there David! Your first post indicates that the reason you won't design the system is because the BS for domestic fire detection is trash and needs starting over (This statement indicates a level of competency in the subject). Your original post indicates that you are also willing to install the products. Nothing in your post indicated that this decision is about the competence of your design knowledge. I would therefore advise that you should not install any fire alarm systems unless you know that they are fully designed in accordance with the relevant standards. Installing these products without ensuring that they have been professionally designed is not in compliance with BS7671 regulation 660.10. A lack of understanding and ignorance (conscious or unconscious is a huge issue in unsatisfactory and unsafe installations in the domestic market where low cost is king. Legislation is all we have to protect ourselves and others from cowboy installations. If you currently have a disability or ill health, I am really sorry for your distress. While concerned with ill health, I am also concerned with dangerous and unsafe installations; therefore, it does not change the status of the original comments made.
As soon as you mention ‘risk assessment’ I realise this country is doomed. People have to do risk assessments to replace a clock battery.
Go back just around 10 years and this nonsense wasn’t around. If you knew all the regulations and abided by then we would get nothing done and that’s where we are heading.
My last job was 70% paperwork and that wasn’t always the case, like writing R.A.Ms for Critical infrastructure and DC systems down to stupid things. I swear most never read them anyway. It’s a joke. Hence, i resigned.
There are easier and less boring ways to earn a living.
Are you out on the tools now then John?
Just because you have little respect for risk assessments does not make it wrong. Perhaps you resignation was a win/win for you and your former employer?
