Hello I am having an issue, I have a trip beam that I hooked up in front of my 150 ft drive way to announce when a vehicle is coming in to the drive way hooked up to the normally open and common contacts from the trip beam. My problem is that thedoor chime goes ding! does anyone have input on a device other that a siren that could annunciate when my trip beams go into alarm. Does anyone know if there a chime of a door bell that could full length when my alarm contact latches. Please help your input will be greatly appreciated. -Sergio former fire alarm inspector

Morning Inq,
I was puzzled why you asked the OP this question.?
In common usage for security work the word 'trip' means to trigger an alarm if a beam or any other detection circuit is broken/tripped.?
Its not to be taken literally as wanting to trip someone up and make them fall over.
It was done to extract more information. As the original post left out too much detail. Was going to answer "Well it has crossed my mind, but would have caused havoc when using the restroom in the middle of the night."
I live out side of town. I want to know if someone drives to my house. I connected a light beam across the road to detect a car in front of the house. A car makes a very short "ding" of the door bell. Then 30 seconds later a person will ring the bell.
My problem is:
1) In very bright sunlight the project does not work.
2) At night it works too well when a deer or elk walk through the yard.
