Which components are essential in an alarm system?

1. Camera, server, monitor

2. Sensor, transmitter, control panel

3. Detector, battery, keypad

4. Alarm, circuit, microphone

The correct answer is: Sensor, transmitter, control panel

The essential components of an alarm system include the sensor, transmitter, and control panel. The sensor is critical as it detects any changes or breaches in the environment, such as movement, opening of doors, or glass breakage. This initial detection is vital for triggering the alarm system. The transmitter then communicates the signal from the sensor to the next component, which is the control panel. The control panel acts as the brain of the alarm system, receiving signals from sensors and processing this information. It can then respond appropriately, such as sending alerts, activating alarms, or notifying a monitoring service. Together, these three components create a functional alarm system that can effectively monitor and respond to security threats. Other options mentioned might include components related to surveillance (cameras and monitors), but they are not fundamental to the operational core of a typical alarm system.
