Intent
Intent 1: 
To limit the probability that normal [high] temperatures in elevator machine rooms will activate sprinklers, which could lead to unwanted water discharge, which could lead to unsafe conditions [e.g. water and electrical equipment causing electrocution] or failure of the elevator system, which could lead to harm to persons.
Intent 2: 
To limit the probability that sprinklers will be damaged [e.g. accidental impact by service personnel], which could lead to unwanted water discharge, which could lead to unsafe conditions [e.g. water and electrical equipment causing electrocution] or failure of the elevator system, which could lead to harm to persons.
