The Howe-Transmitters running in sequence! Per-round non-interference, I’ve never seen this before!

God bless you!

This is actually pretty unique system like the coding you had it set on definitely reminds me of turn signals in school buses or Chevy express vans

[@LXXero]

The original impulse generator was a spinning-motorized device that looked a bit like a car alternator / magneto type thing, and likely didn’t click this way, only the transmitter would have, but short of finding the original I am simulating the impulses with a relay, thus the clicking (that isn’t from the Howe itself). All said, you end up with at least 3 things clicking when an actual code is firing….

@@LXXero that is so cool and very unique so it’s basically kind of like code wheel to a fire alarm panel, except it has to pulse on and off in order for it to work just like a single stroke bell

@@firealarm2903 yup, it’s exactly like a single stroke bell in that regard, each transmitter moves one click per stroke of the solenoid. it’s possibly the earliest form of a fire alarm sync protocol, if you think about it! It just wasn’t used for strobes or horns but rather the code wheels on the pulls themselves would be in sync, that same step-by-step movement allowed them to interleave code rounds and get codes sent in faster from multiple stations, versus normal coded stations, which had to complete their full set of 4 rounds before handoff to the next. it’s an intriguing concept, and quite a feat to have pulled this off almost entirely electromechanically.

@@LXXero that’s pretty cool how this thing operated electro mechanically for the earliest form of Sync protocols. if I had one of these, I’d hook it up to a 2001 panel and have it set to 90 bpm March time since these things work up to a maximum of 100 bpm for these transmitters
