One of the questions that quite a few folks ask about from time to time is How do I install a weight alarm buzzer into my Cardinal Scale weight indicator to let me know when a truck is on my scale? Of course the driver could just call the scale operator using a cell phone. Or, the truck driver could lay on his horn until somebody noticed. Well, those are probably not the best choices. This installation is most commonly requested for the Cardinal 225 indicator, although a similar setup can be done on the advanced 825 from Cardinal.

For the 225, you will need to purchase Cardinal part number 6620-0016 which should mount in place of the larger gland connector in the back of the 225. The red wire for the buzzer will plug into pin 2 of the P15 connector. The black wire will plug into pin 10 of P15. Once this is connected, enable the weight alarm within the ID Storage mode of operation settings.
