I wanted to use my Motor Horn with one of my New/Old 4903-9101 but the 4903-9101 is 24V and the Motor Horn is 12V. The Manual says it can run on 24V but every time I try it on 24V it sounds a bit higher pitched compared to it on 12V.
Is it supposed to sound this way?
Here is the Manual for Help:
That might have to do with being fed more amps at 24VDC than 12VDC (or maybe the voltage difference itself somehow).
I find it odd that according to the datasheet at least it’s 85dB at 6VDC, then 88dB at 12VDC, but then back down to 85dB at 24VDC: one would think that the decibel rating would go up as the voltage goes up.
I find that Odd Too. Will it be okay if I use it on 24V? Or is that just talking about 24V Models?
Going by the data sheet powering it at any of the listed voltages should be fine: no idea how Amseco engineered their BZ-54-series motor horns to run on 6, 12, & 24VDC but they apparently did somehow!
Thanks! I’m glad I can Run the Amseco Motor Horn on 24V without Damaging it.
Also on top of it Working on 6V. I tried it on 6V but it was very Quiet. I guess they tried making it stand out from other Mechanical Horns.
It’s literally a brushed DC motor inside those things, it will spin faster when it gets more voltage. Motor horn is literal, there’s a motor in there that spins and smacks against the horn to make noise. Take the back off some day, you’re in for a surprise
Yep: apparently it wasn’t a very popular concept however seeing as how Amseco were really the only ones to try it. I’m not sure the back can be taken off these horns though (including without damaging the mechanism or the latter falling apart).
