This means that the system isn't set up correctly (obviously).... the fault could be any of the room sensors or window sensors (depending on what system you have) or even the front panel of the alarm box not being fully shut. Either way you need to get the tamper light off before it will work reliably again. Even the wires connecting the panel to the sensors has an anti tamper loop in them - any cable damage will cause your problem.
