How can I design an ERD(Entity-Relationship Diagram) for a fire and security alarm monitoring System

How can I design an   ERD(Entity-Relationship Diagram) for a fire and security alarm monitoring System taking into consideration that it may require an automated alaram system which monitors all the fire and security in the building. The factors that I should take into consideration are:
– If the control area is unmanned and an alarm is activated this alarm should not be ignored if it is potentially serious. Emergency services should be automatically called. – Some but not all parts of the building may be equipped with sprinkler systems or systems
to shut down electrical equipment. These should be activated if a fire alarm is confirmed. They should not be activated if there are people in the same room. -The building may be equipped with direction indicators which illuminate the route to the
nearest exit. These should be activated when a fire alarm is confirmed. At the same
time, an audible signal should sound alerting occupiers to leave the building. -A security alarm may cause some internal doors to be locked automatically. It should be possible to isolate complete zones by automatic door lockin
