OK, I did that, and it does let me run the strobe off the horn if the wires are connected to the "STROBE"-labeled terminals. But not the "AUDIBLE"-labeled ones. Guess if I want to do 4-wire operation I'd need quite a bit of 9-volt batteries (these seem to work for me when I test them.)Fire Alarm Fan wrote:Look to the strobe side of the terminal block. There should be 3 flat pins sticking up from the PCB, labeled WP1 - WP3. Notice that WP2 has a + by it, and WP3 has the -. Hook the wires from the VA4 to those.
But besides that, I got some more new alarm devices:
Here we have an OLD IBM 4251-1 pull station. I think it dates back to the 1950s, as I don't think IBM began rebranding Couch's pull stations until then. The lock is broken on the top, so I often have the lever pulled to keep the station in place.
Wheelock AS horn/strobe. This one is the 12VDC version (supports up to around 18VDC, not sure if I want to run it on 24-27VDC). It's also a two-wire horn/strobe. I currently set the volume jumper to "LOW," and have it set on Code-3. The strobe is 15/75 candelas.
I also got three of these Simplex TrueAlert horn/strobes. They are 4903-9418s, to be exact. They are also 2-wire horn/strobes, but I do not have a SmartSync module to make the horn sound (I CAN get the strobe to flash, though).
My fourth TrueAlert horn/strobe. Unlike the others, THIS one is white and multi-candela. It is also a two-wire horn/strobe, but I haven't tested it yet.
The Faraday stuff in my fire alarm collection.
The "Misc. companies" stuff in my collection, including System Sensor (for now), Space Age Electronics and Standard Electric Time.
The Wheelock devices in my collection so far.
All the Simplex devices in my collection. I've got a LOT.
