This past weekend, I had the chance to visit an old house in Northeast Portland—and it was a really weird house. For starters, the staircase to the upstairs was located in the downstairs bathroom. But I spotted this thing on the wall of one of the rooms and wondered, what is that? It looked like an old-timey schoolroom bell, but it turned out to be an old-school fire alarm, apparently still installed.
I thought it was cool. You probably don’t, but if you do, there are more pics and details after the jump.

The thing’s a precursor to a modern-day, battery-powered smoke alarm, and it was originally connected to a selection of the rooms in the house. (There were four sensors total.) The bell, however, would only ring in this downstairs room. I’m assuming it was loud enough to hear from the upstairs.

It even had the user’s manual still inside. Judging by the contents of manual, the system must have been installed in 1958 by a company called the American Fire Alarm Co., located on SE Powell.

I believe the American Fire Alarm Co. went on to become—or is in some way connected to—the American Fire Prevention Co., which is still in business at 512 SE 9th Ave, but there are a couple things here that get me. Note the “BE” prefix to the phone number (which stood for BElmont, which I guess was the phone keyword for the area), plus the baffling “Portland 2” address. Was this because “Portland 1” was in Maine? Or was Portland divided into two sections before ZIP codes became ubiquitous?
If any local history buffs have more info, let me know in the comments. In the meantime, this was a cool old thing to come across. I didn’t have the chance to test it to see if it still worked, but I gather at one time this was a top-of-the-line system.

The Radio Cab building at NW 16th and Lovejoy still advertises their phone number as CA7-1212.
22X (CApital) and 23X (BElmont) are a couple of the city’s oldest exchanges.
Great find, Ned! I’m a total history nerd, so I certainly appreciated the post. Maybe check with the folks that run the Lost Oregon blog? They might know the answers to some of those unanswered questions or be able to direct you to someone who does.
Before zip codes large cities were divided into zones in order to manage the mail more efficiently. Google helps us to learn that these zones were instituted in the 40s.

‘Thumbs up’ on this post, Ned.
Thanks, spudboy. What did you google? “Portland 2” got me nowhere.
Aha, a little more “google”-ing shows that zone 2 indeed predates the ZIP code, and now corresponds to the 97202 ZIP code. When ZIPs were instituted, they pasted 97 (for Oregon) and 2 (for Portland) in front of each of these postal zone numbers.

The house I grew up in has a hilarious fire-suppression system. There are these grapefruit-sized, teardrop-shaped glass bulbs full of some type of clear liquid. They hang over interior doors and are held in place by a very thin band of metal designed to snap under intense heat. I’m not sure what the liquid is, but if that house ever burns, the only thing they’re going to do is dump broken glass everywhere and maybe even clock somebody trying to escape. Not sure why my folks’ve never taken them down. Dark whimsy?
Thanks Ned. More antiquated technology posts!
We need pictures of those, Carl.
Supposedly those glass bulbs can kill you!
Many were filled with Carbon Tetrachloride, same as the extinguishers mentioned here:

It produces gas that robs the fire of oxygen. But heat from the fire can transform it into phosgene, aka WWI nerve gas!
Crazy stuff.
@Carl: Something like this?

You seem to have figured out a better search string, Ned, but what I used was something like “pre-zip postal code,” without the quotes…
Good finds, though. I always wondered why Portland’s zip codes were all out of order like they are…
Wow, those things are weird. I’ll ask my dad if he remembers them.
Almost exactly, Atomic. Ours just drop, though. The mount doesn’t “hurl” as that one does.
Seemed like a good idea at the time!
