Yessiree: lots of detectors with that design were made over the years (likely mainly during the 80s if I had to guess, though maybe also into the 90s as well). Definitely neat that most of the heads & bases shown there are interchangable with each other in addition to other 2098-series heads & bases too. Is that truly every model there is though?
Any idea what the difference between the 9636 & 9637 is? I’m not sure I see any (if I had to guess the 9635 doesn’t have an LED unlike the 9636 & 9637 since it’s meant for mounting on a base that has its own LED). Oh: also the 9508 & 9544 (aside from maybe the same LED-related thing as the 9636 & 9637).
Interesting how the 4262-20 has quite a few differences in design to every other “wiffle-ball” head & base that Hochiki made & that Simplex rebranded from them (was it the very first made, & if so when?).
One other thing: from what I’ve seen short “wiffle-ball” heads are ionization, while tall ones are photoelectric.
Do you have an example photo? I’m not sure I know what you’re referring to.
The majority of the whiffle ball type detectors were first manufactured the mid 80’s (1986 is the earliest source form Hochiki I can find)
From browsing documents, yes? I feel like there might be an ion duct detector as well. There’s also the 12V models, but those would be Hochiki only as far as I know and probably have the same model numbers anyways.
The only difference I can find is the power LED doesn’t blink unlike the -9636. (It’s also the -9647, not -9637. The -9637 is a base)
Exactly. It’s older (first mention is unknown, although likely 1981-1984), and Hochiki didn’t bother with an LED apparently, probably for cost reasons.
I think there’s an earlier PID series detector, not sure in the model though (might just be PID). The earliest I can find for the PID-B is 1976, and mine is dated April of 1980
Oh, alright, neat. Ah yes: didn’t realize that myself.
Yeah, though like I said it seems to have been meant for use with bases that have LEDs (rather than the head having the LED). Not sure what’s up with some detectors not having flashing power LEDs as standard though (& not just ones from back in the day: even Apollo’s current 65-series doesn’t have such by default! (in fact you have to literally buy a specific model just to get the flashing power LED version!).
Oh, okay, didn’t know about those until now actually.
Thinking that a good nickname for the one on the left would be “shower head” or “sink drain cover”, heh (what is that metal disc exactly?).
That’s actually the heat sensor. The plastic around it is a cage to protect it I guess. They’re probably the only fixed-temp only detectors I know that are multi use.
Oh? Uh, okay I guess…(don’t know how that would work if fixed detectors are almost always designed to be one-time-use only, but alright)
Exactly: what the heck Apollo? Do they not realize how much easier it is to be able to watch a detector’s LED flash to make sure it’s working as opposed to having to actually activate it to tell? (heck I’m surprised this was an afterthought on really old detectors too!)
