Which of the following is best for reducing the number of nuisance alarms?

Nuisance alarms, particularly from doors, are often caused by mechanical failures such as worn hinges, faulty magnetic switches, or misaligned contacts. Regular inspections and maintenance are the most effective way to reduce false alarms.

Signage (A) helps inform but doesn’t fix the mechanical issue.

Patrols (C) are reactive, not preventative.

Janitorial scheduling (D) can reduce traffic but doesn’t address faulty hardware.
