An automatic fire alarm system is designed for detecting the unwanted presence of fire by
monitoring environmental changes associated with combustion. In general, a fire alarm system is
classified as either automatically actuated, manually actuated, or both. Automatic fire alarm
systems are intended to notify the building occupants to evacuate in the event of a fire or other
emergency, to report the event to an off-premises location in order to summon emergency
services, and to prepare the structure and associated systems to control the spread of fire and
smoke.

and chemical agents to extinguish a fire.
Answer option A is incorrect. A fire sprinkler is the part of a fire sprinkler system that discharges
water when the effects of a fire have been detected, such as when a predetermined temperature
has been reached.
