First off, this whole concept of getting an alarmed sensor from the local Harbor freight isn’t mine. It has been suggested a few times on these forums, and to the folks that put this suggestion out, I want to thank them. This post is just me modifying it.
Currently, if you head down to your local harbor freight, armed with your coupon booklet, these can be had for a bit over $9 till the end of this month. Normally, they are almost $15. I picked up two for that sweet price.
For those that that don’t know, in the box you’ll find a separate sensor that works off of a 9v battery. It is made to be out in the weather, the battery compartment has an O ring seal. The second piece is the receiver, that gives you two options to hear the alarm once the outdoor sensor picks up movement(up to 400’ away), and all that is is a low volume alarm and a high volume. 3 LED lights simultaneously flash on for a second when first turned on. This receiver takes 3 C batteries, and by the way, batteries are not included with the purchase of this thing.
so, what some have done, to get rid of the alarm feature, is open it up(6 screws) and cut a wire to the speaker to disable the alarm. So, from now on, all you will see is a flash of the LED’s once the outside sensor detects movement. I like the alarm feature, but when you have a wife that uses her ears for a living and has super woman hearing to begin with, you disconnect the speaker.
But, I like the alarm feature, when she’s gone off to work, so I installed an inline switch. There’s not a lot of room inside the receiver, as the battery compartment and the electrical board take up a lot of space. So I headed off to my local ACE hardware in search for a low profile toggle switch.
