I've got a UV system for killing bugs in a water system. Works fine. Just no one hears the alarm when it goes off.

The controller of the UV does have Dry Contacts (COM,NC,NO) for other options, ie solenoid, bigger/remote alarm, lights etc

I've got a bit of a electronics background but I'm no electrician.

Can someone recommend product(s) that can use the dry contacts switch to turn off the power to the pump?

Googling around doesn't really turn up much of any use other than marine products or other lower powered relays.

Thanks!
