Welcome, & nice collection so far!
I don’t I think, outside of it potentially being a predecessor to the SA67D (which also had a bigger cover like the SA76RD at first).
Thank you. Even though my SA76RD came in it’s original box with it’s manual and warranty, it has been hard to find specifics online.
According to this post on this topic, the SA76RD (along with the very similar SA67D) succeeded the SA76RC (which in itself was a successor to the SA76RS (same as the RC, but with an electromechanical horn), though I’m honestly not sure what the exact differences are between the SA76RD & the SA67D (maybe if a veteran smoke detector collector shows up here they can give us an answer or two to this).
The difference is usually the button as the SA76RD’s used a clear button and the 1st gen SA67D’s used a white button. However, we have seen very rare later SA67D 1st gens with the clear button, so for the most part its just a change in model numbers.
Oh, really? Huh, that’s odd: heck one would think that the white button model would have come first. Wonder why BRK decided to switch from “SA76” to “SA67” though (& for that matter why they eventually replaced the SA76RD with the SA67D considering they’re essentially the same unit).
I believe the SA67D 1st gens with the white buttons were meant to be the successor to the SA67 and just gradually became the main model number for First Alerts 90s units.
Yeah also I’m kind of curious how rare the SA76RD is
Pretty dang rare as far as I know at least, since I only knew about the SA67D previously (heck it wouldn’t surprise me if the SA67D far outlasted the SA76RD production run-wise given how seemingly rare the latter is).
Also originally before I decided to get the SA76RD I was gonna get a first generation SA67D
Oh? Well, I’d say it’s a good thing you ultimately didn’t considering how semi-more-common 1st-gen SA67Ds are compared to SA76RDs!
I considered quite a few other alarms before this one the first being a newer Kidde and I don’t understand how I thought they looked good then cause personally I think they look really bad
Look at the inside of the unit, if it has the “false alarm sensor”. You got a rare one from around 1984-1985. I can help you determine
Okay I looked closer at the image, it is indeed a rare variant with the false alarm sensor, nice!
Nice! would you like an image of the inside of it?
Yes, I would like to see it
That is indeed from 1985. The numbers on the sensor is how I determine the date. Since it begins with a 5, indicating the last digit of the year, that means this version is from 1985. You do have to consider the range they were made and all that
Eh, maybe, but from a preservational perspective I’d say they’re all welcome, heh.
Is that why BRK switched to a larger metal sensing chamber cover later on?
Yes it is, they were prone to falsing in a rapid abnormal tone.
