We have a tamper switch on a remote sprinkler valve that needs to be supervised at the fire panel. We have looked at trenching out to the valve but it is not going to be easy. One of our electricians said that he had seen a similar situation solved with a remote wireless switch which interfaced to a receiver back at the panel. I have called a few places and can't find any device that is UL approved for fire alarm applications. Does anyone know of a device that is UL approved and who makes it?
Thanks
