What are common causes of false alarms in alarm systems and how can they be reduced?

• A. Poor internet connectivity and power outages; ignoring maintenance.
• B. Weather patterns alone; replacing devices monthly.
• C. Sensor malfunctions, environmental factors, human error; regular maintenance, correct sensor placement, testing, and up-to-date procedures.
• D. Training gaps; increasing alarm thresholds.

Answer: (C)

False alarms happen when a system triggers without an actual intrusion, and the main causes are sensor malfunctions, environmental factors, and human error. Regular maintenance, correct sensor placement, testing, and up-to-date procedures address these issues by ensuring sensors operate properly, aren’t overly sensitive to non-threat sources, and are configured and used consistently. Regular maintenance catches degraded components and dirty lenses, correct placement reduces nuisance triggers from dust, steam, or pets, and testing validates that sensitivity and zones work as intended. Updating procedures keeps staff trained and configurations current, preventing misconfigurations that lead to unnecessary alarms.
