Which of the following is likely to reduce the number of unwarranted alarms?

Proper installation and maintenance are crucial in ensuring that fire alarm systems function correctly and efficiently. When alarms are installed according to manufacturer specifications and relevant codes, it minimizes the chances of false alarms triggered by improper placement or faulty connections.

Regular maintenance involves checking for any wear and tear, ensuring all components are working as intended, and recalibrating sensors when necessary. This proactive approach helps identify potential issues before they lead to false alarms. For example, ensuring that smoke detectors are installed away from sources of steam or dust can prevent nuisance alarms that would occur if they were placed too close to these environments.

A well-maintained system will not only operate effectively under normal conditions, but it will also be less sensitive to common causes of false alarms, thereby reducing unwarranted activations.
