I'm going to help you out a little here because I don't want this section to unnecessarily take up too much time or effort, which will take away from its enjoyment.
Hammer and S'krllk go to work on the nearby computer station. They are able to download a basic schematic for the floor you are on (Level 4). Here is what they find:
You are in room 10 (maintenance room)
Rooms marked 5 are staff and guest (i.e., patient) rooms, and 6 marks the balconies to the rooms that overlook the steep cliff you just climbed.
Room 11 is a storeroom with typical nonfood items stored. (You don't know exactly what at this point.)
Room 12 is a robot storeroom, which stores, not surprisingly, robots and their parts, along with charging stations.
The places marked with a "3" are the elevators on the floor. There are three total.
A circled "c" indicates where a security camera is mounted.
You also discover that there are invisible infrared beams at the location marked IR, and are likely tied to an alarm.
A door with a dot means the door is security locked. (As you can see, on this level, they are to make sure the "patients" do not leave their areas or escape.
The two doors leading to the maintenance room are in the form of an airlock door to maintain pressurization of the inside of the sanitarium (since the area you are at has that direct garbage chute that would interfere with that. The airlocks are not locked.
