After months of putting this off, I'm now ready to showcase my current device collection.

Image
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.

Image
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.

Image
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.

Image
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.

This is my Edwards 17 bell, which was the first fire alarm-related device I bought for my collection (from a garage sale). The diameter of the gong is approximately 5.5" across.

The back of the device, which shows part of the wiring and interior housing.

Next up is my Edwards Adaptabel model 332, which I purchased from a flea market. There are similar versions of this bell online with a different tag on front; this looks to be an older bell, judging by the amount of wear on the surface.

Image
The back of the bell shows the exposed single-stroke mechanism.

The next item in my collection is this 2" bell I bought from a flea market. I believe this bell is made by Liberty Bell Manufacturing Co. based on an eBay marketplace listing for this item showing a bell striker exactly like the one I have. The reason there is no cover plate for the interior mechanisms is because when I bought this bell, it was missing the cover.

This is my Fire-Lite-branded BG-12LX, which I purchased from a flea market.

Image
When I bought this pull station, it did not come with a key, and the lock mechanism is therefore stuck in the 'unlocked' position, meaning that the pull station does not close properly. Everything else is in working condition, however.

Image
This device appears to have been previously used in an installation, judging by the spliced wires on the back casing. Also, there are several black (paint?) stains on the wires and the edges of all four sides on the back.

And now, for the last two items in my collection:

Image
This is my National Time & Signal Corporation 641 pull station, a device that is gradually getting rarer to find. These were once common in several regions of Michigan (including my hometown), but with new system upgrades and removals, these have been disappearing.

Image
The device when it's in alarm.

Image
A special key is used to unlock the device and expose the inner components, but the one I bought (from a flea market) did not come with such a key. However, I suspect that a long-enough circular object or two could be inserted and do the same thing.

Image
The back of the device, showing off the old wiring.

Image
Lastly, also from National Time, is my 311 fire horn. Also once common in several areas of Michigan (e.g., Strong Hall at Eastern Michigan University, Jackson Early Childhood Center (Livonia), Jewish Community Center (Oak Park)), this device has become scarce.

Image
This may be the heaviest device I own in my collection. It could be installed as a flush-mount horn, or it could be installed on a backplate with two screws, as shown here.

Image
Although National Time has its name on the device, Federal Signal Corporation and Standard Electric Time Co. have also distributed this type of horn under their own labels.

Image
The back of the device, showing more of the backplate including the wiring and several holes of unknown origin.

This will be the last update I make to this post for quite a long time. I hope to acquire more devices in the coming months to exhibit, but I don't have a time frame for when that will be.

Really nice collection! Is there National Time horns the ones that sound like an Edwards Adaptahorn?

I have not tested the National Time 331 for myself, so I cannot say for sure. I've heard recordings of the horn online, used as buzzers for vintage scoreboards.

Basically like these is what I'm asking if they sound like or if that was the 411s.

Neither the 311 nor the 411 series of horns sound like the devices in the video. If I had to guess, the Federal Signal devices in the video are most likely a modern, enhanced version of the originals that sound in different keys.

I bought a new device for my collection!

Image
This is a bell with a circuit box and striker for the gong (2" in diameter). The previous owner of this device had the bell mounted onto this wooden plaque, but I couldn't find any screws nor other compartments with which to disassemble the device from the plaque.

Image
As you can see, this device originally was installed in a telephone exchange building of the old Bell System. The bell would sound most likely whenever a telephone call came in. I don't know the model nor the manufacturer of this device; Western Electric produced a majority of the telephone ringer bells for the Bell System, but I could not find any Western Electric logo stamped on this device.

They sound like that because they run on DC. AC devices (whether it be a fridge, street lamp, fire alarm, or dryer buzzer) have a 120 Hz tone or undertone due to the 60 Hz wave of the current. In the UK, they have a 100 Hz tone because theirs is 50 Hz.

Did you hear about the film director who collected fire alarms?

I didn't know that there were round Adaptahorns that were DC. You learn something new every day.

After over a year of inactivity in buying new devices, I finally got a couple of opportunities over the past two weekends to expand my collection! As I now have more dependable transportation to visit places I want to visit, I am planning on looking for more devices in the coming months.

Image
This is my Kidde Model 0914 smoke detector, under the Fire Sentry brand.

Image
The device looks to have been manufactured in the mid-1990s, judging by older NFPA household smoke alarm installation standards.

Image

Image

Image
Despite wear and tear on the original packaging, this detector was never used before--it still contains its original battery.

Image

Image
This is my Pittway Corporation 83R smoke detector from 1988, under the First Alert brand. This type of detector used to be installed in one of the homes I lived in.

Image

Image
I bought this detector with my Kidde 0914 device in the same sale I was at.

Image
Like the Kidde detector, this alarm looks to have never been used, either, judging by the mounting brackets and nails still in their original packaging inside the detector.

Image
Unlike the Kidde detector, this device is missing its instruction manual.

Image
Last, but not least, is my Ademco AD8 fire bell! I found this at an outdoor flea market. There's a yellow dot where the strike mechanism is supposed to be aligned to during installation.
