BMW does not turn on alarm connecting

Well greetings from the island of the charm I just bought a BMW 325i of 1993 in good condition and when putting the battery which has been back in turn. But Lugo left him stand for several months and when he turned it on again with a fresh battery I connected the alarm, that is, I began to blinate all the "dash" and made the attempt to turn I don't think it's a signal.
If Tarch has the masibility of telling me what to do to reset the alrma or something else
