Smoke detector alarm

Step 4 Now for a trigger!

Now find a suitable way to set off the alarm, Pressure switch, push button, Reed switch (my fav), or door switch (same as a reed switch but better for mounting on doors/windows.

The pictures below show a couple of the switches I used below to sound my alarm.

First one is the door switch (obtained from an unused security system in a wharehouse)pic1 shows door switch off pic2 shows it in the on position. -=p

Second is my Favorite it's a "REED" switch,Just wired one of those things up inside a DVD case & I used a magnet inside of an old newport box simple yet effective. -=]
When the 'Ewport' (not a typo) box was picked up the alarm would sound, It helps if you run long wires from the detector & hide it much funnier.

I made a stash box version of this alarm using the pressure sensitive switch out of an old phone hangup button I'll be posting it soon.

Well have fun with it as you may, just be careful these things contain RADIATION, So don't go putting it around young children or animals NOT COOL!

Feel free to ask me if you have a question about anything posted.

Sorry for the delay in response..(relocating issues) But the alarm described cannot be used as a smoke detector with this configuration. Because when power is switched "ON" (Via trigger/switch) to the device the "TEST" button outputs the power to the siren. Thus bypassing it's smoke sensor that would usually trigger the siren.

does the smoke detector work as a smoke detector and a alarm also
