Intent
Intent 1: 
To limit the probability that an inappropriate type of fire alarm system [e.g. single stage system] will be used for an area where persons are unable to move by themselves, which could lead to:
  • their unnecessary evacuation in response to a false or unwanted alarm, which could lead to harm to persons, and
  • designated persons [staff] being unaware or misinformed as to the type of fire emergency, which could lead to inappropriate actions being taken, which could lead to delays in evacuation or moving to a safe place, which could lead to harm to persons.
