After months of putting this off, I’m now ready to showcase my current device collection.
This is my entire collection as it stands so far. I first started collecting in the summer of 2013/2014 with the Edwards 17 bell as shown. I plan on describing each of my devices individually in a short series of pictures. It may be a long time before I add a new piece to the collection because I do not yet have the cash flow or resources set up to purchase devices.
This is my Norelco HB-0933 smoke detector. I believe it was originally installed sometime in the early 1970s in a house our family has been rehabilitating since last year. When I first got it from being taken down, it was stained from tobacco and required surface cleaning along with cleaning a little of the interior housing. There is a similar model to this that features a push-button on the logo to test the device.
Here is the interior of the front cover, containing notices of UL certification, testing instructions, instructions for battery replacement, and others. Also notice a few dates to the left, which may denote times this detector was tested by the previous owners.
The interior housing can be accessed by rotating the outer cover about 45 degrees; shown here is the piezo, circuitry, wiring, and the “Replace Battery” tab which I had to manually reset since it does not reset on its own. I have not tested this detector at all since first acquiring it, so I am unsure of its operating status.
