I bought another 2x 433mhz smoke alarms today taking my count up to 3.
I plan to put 1 in the garage coz I have lithium batteries for my remote controls and those bad boys know how to start a fire and 1 in the roof coz despite my best efforts to keep leaves out the neighbours trees leaves still end up collecting in there.
Having LED's down lights and a fireplace I am always worried about the leaves getting onto the back of the LED heat sinks or on the flue pipe and starting a fire and not knowing about it till a neighbour points out my house is sending smoke signals.
Has anyone else put smoke alarms in their roof space?

Has anyone else put smoke alarms in their roof space? I bought 1 433mhz smoke alarm out of curiosity (well, also to add to the reaction time for emergencies haha..) and tried to test it by burning a tissue.. however it didn't react as I would like. Most probably due to the smoke generated being too minute. But no, not in my roof space..... yet  |

Good point, I have never tested it with smoke to see if they actually work. I know you can create alot of smoke quickly if you wrap a ping pong ball in alfoil and heat it with a cigarette lighter.

This has been sitting in the back of my mind now on how much smoke is needed to set these wireless smoke detectors off. I have 3 of the wireless sensors in my kitchen/garage ceiling space and 1x hardwired unit in the hallway that I bought from the local hardware store.
When wife cooks she has a habit of burning things (still better than my cooking), the sensor in the kitchen has not once gone off yet the hardwired unit I got from the hardware store which is around the corner and down the hallway does trigger.
So now I am wondering whether these wireless detectors that are sold on ebay actually work and just how much smoke is it going to take before they go off.

If you smoke,light a cigarette & blow the smoke into the sensor & watch how long it takes to react. Basically a smoke detector are more useful for central air-conditioner application. Whereby it will shutdown the air-conditioner if it detected smoke to prevent the spread of smoke to other rooms. Disable the escape route.

Nope I don't smoke. I have never heard of this as application for smoke detectors (shut down aircon), great information I have learnt something new today.
ps I have not tested my ebay wireless smoke alarms yet), I can tell you though everytime I look at them I am not in a trusting mood with them. I have my original smoke alarm still hooked up which I know works quiet well.
