Which type of systems utilize conventional sensors and notification devices such as bells and lights?

Hardwired systems are designed to utilize physical connections between various components, such as sensors, notification devices, and the control panel. The conventional sensors in hardwired systems are often linked using copper wires, which allows for real-time communication of detected intrusions or events to the monitoring system.

Notification devices in these systems, such as bells, sirens, or flashing lights, serve as direct alerts to unauthorized access or other security breaches. Because hardwired systems rely on physical wiring, they often provide a stable and reliable method of monitoring, making them a popular choice for traditional security implementations.

In contrast, wireless systems use radio signals to communicate between components, which can enable more flexible installation but may involve different technologies and operational characteristics. Smart systems typically incorporate advanced technologies and network connectivity, often allowing for remote monitoring and control, while integrated systems might involve a combination of different types of security solutions working together. However, it is the hardwired systems that specifically utilize conventional sensors and notification devices in a straightforward manner.
