The sensory system primarily engaged by audible fire alarms is the auditory system. This is because fire alarms are designed to produce sound, such as loud beeping or sirens, which alert individuals to potential danger. The auditory system is responsible for processing sound waves, allowing people to detect the alarm and react accordingly.

In emergency situations, where immediate attention is crucial, sound serves as an effective and rapid means of alerting occupants to evacuate or seek safety. The loudness and distinctive nature of fire alarm sounds are specifically intended to penetrate background noise and ensure that the alarm is heard, facilitating a quick response.

The other sensory systems mentioned do not play a primary role in the function of audible fire alarms. The visual system relies on sight, which is not the primary method of notification in this context. The olfactory system pertains to the sense of smell, which is not applicable as fire alarms do not emit scents but rather sounds. The tactile system involves the sense of touch, which is also not relevant since the alarms are auditory in nature. Thus, engaging the auditory system is essential for the effectiveness of fire alarms in alerting individuals to danger.
