What is a common issue that can lead to unwarranted alarms?

The common issue that can lead to unwarranted alarms is improper installation of systems. When a one-way voice communication system, or any fire safety system, is not installed correctly, it can cause false alarms. For instance, if sensors are poorly placed or not calibrated properly, they may trigger unexpectedly, leading to confusion and a potential loss of confidence in the alarm system. This is particularly critical in emergency situations where reliable communication is essential for safety and coordination. Therefore, ensuring proper installation following the manufacturer's guidelines and industry standards is vital in preventing such unwanted alarm occurrences.
