Answer:
A fire alarm system has several devices working together to detect and warn people when smoke, or fire or other emergencies are present. Fire alarm sounders can be installed to certain frequencies and different tones including low, medium, and high. They are for detecting dense smoke and they are less prone to false alarms from cooking fumes or shower steam. Unfortunately, they're sensitive to dust particles and insects, meaning that regular maintenance is required. Ionization smoke alarms are excellent at identifying kitchen fires. Nevertheless, ionization alarms are prone to false alarms possibly due to high humidity since humidity provides dense moisture particles. Another type of smoke alarm is a photoelectric smoke alarm that tends to respond faster to smoke generated by the burning flames. A disadvantage is it is costly as well as it is predisposed to nuisance alarms from dust and insects and must be kept clean.
