Quell Smoke Alarms: Ionisation for Living Areas $8.95 / Photoelectric for Kitchen $14.95 @ Dick Smith

100

Quell Ionisation Smoke Alarm Q946 for Living Areas $8.95
Quell Photoelectric Smoke Alarm Q301H for Kitchens $14.95
Quell Q1300 240v Photoelectric Smoke Alarm - Living areas or hallway $24.95 Page 404'd…. Dick strikes again.

Great prices for these alarms at Dick Smith. Clearance items - so stock is limited.

Though considering the current situation of Dick, if the alarms are in stock, I would recommend going into the physical store first to confirm stock, and then ordering them while in store, to have the workers instantly fulfill the C&C order for you. (To avoid the 'refunds' that may take 214092 years to come)

    Just in case people wonder why not all smoke alarms are made equal.

  • Putting in a few postcodes, here is what i found:

    Ionisation - Wetherill Park, Merrylands, Carindale, Rouse hill, Top Ryde, Pacific Fair, Ipswich, Redbank, Baldivis, Colonnades

    Photoelectric - Sydney George Street, Emporium, Merrylands, Rouse Hill, Goulburn, Southland, Pacific Fair, Redbank, Baldivis, Phoenix,

  • what's the difference between each of these?

    • The methods in which they detect smoke.

      • Ionisation senses evidence of combusted particles in the air. These are cheap and work well, but you are more likely to experience false alarms due to cooking, etc.
      • PhotoElectric looks for smoke in the air (i.e. the specific wavelengths of smoke particles). These are more expensive, but because there needs to be visible smoke for these to work they are less likely to go off if you are cooking. PhotoElectric alarms also respond more accurately to a wider range of fires.
      • Thanks, here is a reasonable article. For my family I insist a co2 alarm in bedroom and kitchen. I once visited family at uni shared house and the gass stove was left on - no flame - the smoker was out. This happened twice. Thus I use co2 monitor (dual) , a remote alarm for roof space (on and off remote) one wired in, and other rooms dual smoke alarms. Works well when visitors sneek a ciggie .

          It's CO actually, not CO2. Carbon MONoxide is the really dangerous one, because the two free spaces for electrons on the molecule (-2 charge) make it ready and willing to combine with the haemoglobin in blood when inhaled and then actively displaces oxygen in the bloodstream, and then you die! :-)

        • Perhaps someone more knowledgeable could chime in but I can't see a carbon monoxide sensor helping with leaking gas…until it ignites and even then I think you'll find your alarm redundant.

          @douglasb: Thanks my bad. More I read about this the more careful I become. My son rents, but there is a tree monthly inspection of smoke alarms [ old Queenslander home say 80+ years, wooden on stumps].
          How many alarms are either turned off or battery taken out - that bloody beeping noise.

          As for multiple models, we should be careful that we get what we think we get.

    From bunnings… don't think this post is a deal… especially the risk of not getting the fire alarms, and limited stock.

    Ionisation $9.95 http://www.bunnings.com.au/quell-9v-ionisation-smoke-alarm_p…

    Photoelectric $14.95 http://www.bunnings.com.au/fire-sentry-photoelectric-smoke-a…

    • Ionisation - still a possible saving of $1. Photoelectric - I decided to post this because the Quells were very popular and received lots of good feedback last time around.

      • +1

        Yes, my friend. Hence I didn't neg the deal.

    • +2

      Masters have First Alert $7(ionisation) / $14(photoelectric).
      Wait off for usual 10% discount code & pay with (currently 7.5%) discounted gift card to get cheaper.

    From a science point.
    Ionisation smoke alarms work by uses americium 241 which a decay of plutonium basically uses alpha particles (ionising radiation) to charge the air inside the smoke alarm charging the particles in the air.
    Alpha particles from the americium slam into the oxygen and nitrogen molecules leaving charged gas molecules the 9v battery causes the ions to move creating a current. when smokes enters it slows down the ions and they loose charge which causes the current to stop and triggers the alarm.

    Buy in a 3-pack from Mitre10 for 15c more. http://shop.mitre10.com.au/quell-complete-home-smoke-alarm-p…

    I just bought them yesterday

    No deal mate. Not worth wasting your petrol money and time chasing limited stock when you can get it at Bunnings.

  • So why don't they make an alarm with both technologies in it.

    Something ironic about alarms and ordering online with DSE in the same post.

    why is dick smith still allowed to advertise here?

    it is bad enough they are still open for business.

    i find it quite disrespectful that they are pushing their 'sales' here after ripping countless numbers of people of recently.

    I vote dick smith be banned from this site until vouchers are honoured.

    keep your open letter to the public
