I know that there was a video a long while back that showed that the Red DC Adaptahorns could be put on 892 style strobe plates, but how often would that have been done? Is it extremely rare and unlikely to have a system like that? Or could it be done to satisfy building codes?
Also, has anybody ever seen a system that had healthy Adaptahorns? Most of the systems I saw had dying or dead Adaptahorns. Back when they were used as fire alarms.
As an affordable solution, I would say that it was probably done in many instances, just because it has not been tallied at high numbers by certain members does not make it “rare.” You will probably find that anywhere they existed, however changes/upgrades were made on a budget.
People love skimping on the cost of alarms, and there are plenty of companies that know how to look at a system, and bit the job the right way to secure the job.
Those were Edwards’ first horn/strobes prior to the electronic 892 series. They were sold as a single unit and would have both been installed at the same time. I’ve never seen them in public, but there were a few on eBay at one point.
I didn’t think 892s were electronics. They could have different pitches. At least the three in my high school modular building did.
What I am also wondering about are the horns in this video here. They look like Integrities but sound like 892s. Some even have different pitches.
Those are 792-7A series horn/strobes, made around 1992-1995 before the Integrity. They have a potentiometer on the back that allows you to change the pitch. My elementary school had these and they sounded exactly like that video.
OK. So these and some 892s can have different pitches. Thanks for clearing that up.
Also, on eBay, there is an Adaptahorn with a strobe for sale now, but they aren’t connected.
So I just wanna ask real quick, if anybody sees an Adaptahorn with the 892 strobe connected, could they send me a picture so I can see? I am very interested in seeing how they connect.
I once saw a picture of one, lost it now though.
I believe the horn sits on the front of the signal and is held in by screws on the back side, and is held onto a custom backbox with two screws. Could be wrong though.
The horn on those signals is actually slightly different from the one used on surface-mount audible-only versions (885D, 864-FA, etc.) as it is equipped with holes in the upper-right and lower-left corners in order to accommodate screws that would attach the horn to the strobe plate (this would probably allow the horn to be mounted directly to a normal 4" backbox). The “Adaptaplate” mounting plate, which would be used on a surface-mount horn, appears to be integrated to the strobe plate (they seem to have the same mounting options); this can be seen on the picture from the eBay auction for the 895B, although it isn’t really obvious at first glance.
The mounting holes that allow the horn to be attached to the strobe plate can somewhat be seen in this [pretty low-resolution] picture from another past eBay auction.
This is probably why the aforementioned Ebay auction (http://www.ebay.com/itm/NIB-EDWARDS-FIRE-HORN-STROBE-895B-301-24-VDC-/230322120451?pt=BI_Security_Fire_Protection&hash=item35a044a703 shown here) has the horn and strobe plate separate- the horn does not have the right holes.
