Head to the right from where you start, to the North. It will not take long for you to reach the Restricted areas. In the area you will find a break between two restricted areas. Use that to get to the far side of them and turn to the right. On that far side of the Restricted Zone and you will easily be able to see the Alarm Bell. This also cuts down the sheer number of soldiers and guards that you need to deal with. Using this approach, you just have a pair of patrolling soldiers to really worry about.
The first soldier will actually come toward you, if you just take up a hiding position. Let him come over toward you and then take him down. The second soldier is to the East. He moves between the bell and the outer portion of this restricted zone. If you want to avoid him, use the nearby haycart to stay out of his line of sight. From there, just emerge and deal with the bell when he turns away.
