Can someone provide the full solution for this problem here. i got stacked and could not solve it.

the system components:
- 40 rooms - guard house - speaker system
- high alert indicator - mild alert indicator - in use indicator
functionality:
a) the intercom must have a connection from the gate to each room and from each room to another room. to reduce cable runs and minimize cost, a single cat5 cable runs from the room to a central switch in the building. another cable runs from the switch to the gate.
b) connection is establish by entering the room number into the keypad following by some call button. the room number is translated into a unique binary address embedded in the system.
c) when a room is called the buzzer is sounded and a visual indicator blinks on panel in the room.
d) if the call is accepted and the line is busy, all other terminals will have the in use indicator lit.
e) each alert indicator must have a unique code. these function is only activated by the college manager to all connected device. when alert is high, the buzzer must also ring for 30 seconds.
requirements:
to complete this assignment, the following tasks are required:
1. give the binary address for each room and device (speaker and alerts)
2. provide the digital logic for functions b) to c) listed above to be “on” or “off”.
3. provide the digital circuit for functions b) to c) listed above using and and or gates.
4.using a flow chart give the input conditions discuss the process for the following outputs:
a. room 5 on the intercom with the gate.
b. room 13 on the intercom with room 37
c. the manager activating the high alert.
