STH-10 Question

[paul_c]

So I might be getting an Sth-10.
Regarding wiring, I dont need a control box, right? Meaning, is there anything inherently wrong with just giving it power and letting the motor run? Or is there some initial load that needs to be modulated or something? Basically I dont know what a control box is for but as long as one isn't absolutely necessary I'm good to go. Thanks

You are going to need a motor starter for the motor. It needs to be of a rated amperage and horsepower for your motor.

Not if he isn't going to be using a control box. The motor starter is only necessary if there's a timer controlling the siren, or you want it controlled by a manual switch that's not massive (rated for 50A+).

He could use a double-pole switch. I think those are rated for switching two hots. Or better yet, just use a 50 amp breaker as a switch.

Well I am going to be flipping a manual switch most likely, something inline.

Also, do those horns come off easily? Looks like four bolts for each horn maybe?
and would you guys say this siren is most likely about 200lbs?

It'll depend if they're rusted to the stator and/or together. Four bolts is correct: two bolts to the stator and one to a horn on each side. The bolts that help stabilize the circle of horns fit inside a spacer between each horn.

Weight will be determined by hp/phase and if it's including the air intake assembly. If you have a single phase like me it'll be closer to 400-425lbs.

Trust me I've let it scream without a motor starter...just the breaker will do. Just turn it off if the wires or breaker overheat.

Thanks Trey. Guy selling it was telling me it is probably 200lbs lbs (yes, single phase).
If it's four hundred pounds, it's not getting into my pick up truck bed without a crane!

Get a few friends together. Trust me you will get it in.

Its more like 400lbs.
