Monroe Wi's Federal 3T22

[Mark360T]

I went to town today hoping that I would record the 3t22 but come to find out they yes at 11:00. They use to test at 12

If you look at the 3rd pic you can see the damper

Yes, you can.

Our local fire chief had a hissy fit when I asked him about the Hi-Lo settings.

Hi-Lo isn't the best thing for a 3T22. The solenoids can have problems operating and get stuck, which can then lead to air clogs, which can really put some age on a motor. Hi-Lo has a nice sound to it, but it can really hurt the motor because of air being blocked one end then blocked another end.

That doesn't make any sense at all. The solenoids rarely stick, most of the time the spring that holds them open just wears out from metal fatigue and breaks.

It doesn't affect the motor in any way. The motor doesn't care which end the air is coming from. With a blocked intake it actually runs under less load.

Here, let me rephrase that:
Hi-Lo is a nice feature, but when one damper gets stuck closed for a long time, its bad for the motor cause it spins at a higher RPM, like the Vernon 3T22. After a long time a/the solenoid(s) break, that is why many YT 3T22 hi lo videos have a solenoid broken open. Also, I never said they always stick, but the can stick, that is, if you don't take care of it. You check the solenoids every month or so, then you wouldn't have to worry about breaking or sticking.

That siren had all sorts of issues. Both dampers were partially shut, the lower do to a broken spring, and the upper do to bees nesting in the intake and in the solenoid box. Also some genius wired 3 wires into the motor, and it's a single phase siren. Not sure where they hooked up that 3rd wire. Also it sitting unused for as long as it did I'm sure didn't help. Luckily it didn't die before it was taken out of service.

Really? I knew the bottom was closed when they took it down. Why did it sit unused? Also, didn't someone obtain it? Sorry for hijacking the thread.

Dude it's not bad for the motor. The motor will not exceed synchrous speed. If it's three phase it's 3450 RPM, if it's single phase repulsion it will turn a little faster but the motor will not exceed 4000 RPM with both rotors installed. Unless somebody cranked up the brush angle and has it screaming.

The one in vernon had been tampered with and had the brush angle advanced way too far.
