The original alarm box was not loud enough to be heard upstairs, so I had added a louder alarm using a fire alarm bell.
Remember this?
Well I have added some enhancements. Look at this.
I added an on/off switch to make it not ring ever, and a test button switch to make it ring any time I want it to. When it is ringing, I can turn it off without having to unplug anything. And I can make sure that it all works any time I want to by pushing the test button.
Pretty neat.
Oh, and hey, if you think that is cool, look at this!
The bell didn’t seem loud enough either, so I added a new device with a klaxon horn that I can hook up instead. It also has an on/off switch and a test button.
Cool, hunh?
But then, the klaxon wasn’t loud enough either, so I build a relay panel so that I can trigger all of the alarms at the same time.
It has four relays, an on/off switch, a test button, and some really creative wiring. I like the orange wire nuts.
The relay panel is the best!
And…. last but not least, here is the whole setup wired together.
I have been working on my Sump Pump Alarm project again, and I have come up with the wicked awesome Sump Alarm Warning Loud Alarm Bell (SAWLAB) to let me know when the pump isn’t working and the basement is about to flood. Here is what it looks like.
Here’s how it works: When the sump hole fills with water, the Float Switch in the Sump Hole floats to the top, which causes the float switch to close the circuit to the battery pack, which sends 12 Volts to the bell circuit, which makes the Alarm Bell ring. Here is what it sounds like.
Pretty cool, hunh?
What? Of course everybody cares. Just look at how fast the hit counter has been going up recently.
