What type of notification does an ionization detector primarily emit upon detecting smoke?

An ionization detector primarily emits an audible alarm upon detecting smoke. This type of detector is designed to sense smoke particles that disrupt an ionization chamber within its mechanism. When smoke is detected, the internal circuitry reacts by triggering an alarm sound, providing an immediate alert to those in the vicinity. The purpose of this alarm is to effectively warn occupants of a potential fire, allowing them to take necessary precautions or evacuate the area promptly.

In contrast, other types of notifications such as strobe light signals, silent alerts, or visual displays are not typical outputs of ionization detectors. While strobe lights may be used in conjunction with some alarm systems, the primary function of the ionization detector remains based around audible alarms to ensure quick and widespread awareness of fire danger.
