DS12A show tamper on SC1200 possible solution.

[javiert30]

If you are trying to install DS12As in your security console system (SC1200) and even with the cover on the DS12A sensor is closed is giving you tamper message in the SC1200, open it again and you are going to see one little capacitor right in the side of the green led, if that capacitor is too close to the led, your cover is not going to push the tamper switch properly and is going to give you that message even if the cover is close. Just separate that little capacitor a little from the led light and you should be ok, don't throw away that DS12A believing is not working.
