first thing is what bell box have you fitted and is it a new one and second leave the P A link in unless you are wireing up a personal attack alarm and also leave the link in the TAMP unless you are wireing it up to somethink and take the link out of the T A if you have used the T A to wire up the external bell box also take out the link on the keypad TAMP i think that the trouble with the bell only going off for 10 sec is because you are still in the enginneers setup on the external bell box need to know the make and model to more help BAZ26
