Hello, 

 

I stumbled across this old burglar alarm at Goodwill and had to have it... 

 

But once I got it home to play with, it seems it is missing an important piece of its assembly. 

 

I Google searched for an hour trying to find the exact model and pertaining information to see if I could order the missing piece OR DIY myself a substitute piece to make this thing functional again, but can't find anything even resembling this model I have. 

 

Anybody out there have any ideas? There is no clear brand Or model labeling... 

 

Only thing I can find is:

 

"K.H. A241 7904

(OHM) 0.25W

Taiwan

OC" 

^^^ On the back of the speaker/bell of the alarm

 

And

 

"CA328 400B" 

^^^ On the circuit board. 

 

There is a Google Photos album link at the BOTTOM (edit) of this post, it was the only way I could figure out on how to get the pics to you guys, if there is a more direct and/or preferred method of posting pic, simply let me know and I will be happy to oblige... I know some people can be wary of clicking on outside links just to view images. 

 

Thanks in advance!
