i posted a message a few days ago abt my alarm beeping for no reason. today, i went to the same place (computer lab) and the transmitter beeped again. this time i'm positive that i didn't press any buttons. what can possibly be the problem?

 

is it the remote that is beeping (2 way remote)? if it is only doing it in a certian place, it is probably just interferance in that area.
