Will this send 12V power to the output only if the input voltage hits around 12V and not when it is at its usual 6V.

I don't know what voltage/amperage it takes to trigger the relay. The output voltage would match the input voltage, not increase or decrease it.

Is this a continuous duty relay ?

As far as I know it is, I used it to replace my cars blower relay and when that's on it stays on until the end of the drive 20 min to 2 or 3 hours. So I would say yes.

Does this relay make a sound when it closes/opens the circuit?

Yes it does when you install it and turn on the item or you can test it with a 12 volt source, if it doesn't make a clicking noise than it is no good and needs to be replaced.

What amperage rating is this relay?

Hi, I looked on the relay and did not see a amperage rating. I used it for my tc40 tractor. it was used for the glow plugs so it may be on the higher side. good luck, don
