Which of the following best describes the function of a tamper switch in an alarm system?
A tamper switch is designed to detect unauthorized access to the alarm panel or other secured components. When the panel cover is removed or tampered with, the switch sends an alert to the alarm control panel, signaling potential interference. This is a security measure to prevent disabling the alarm without proper authorization.
Which of the following is the primary purpose of an end-of-line (EOL) resistor in a wired alarm system?
An end-of-line (EOL) resistor is used to monitor the integrity of a wired alarm circuit. By completing the circuit at the end of each zone's wiring loop, it prevents tampering and ensures the system can detect if a wire is cut or damaged. Without an EOL resistor, the system may not recognize if a connection has been broken, which could lead to undetected vulnerabilities.
What is the purpose of a Z-Wave module in modern alarm systems?
Z-Wave is a wireless communication protocol that enables alarm systems to connect to smart home devices like lights, locks, and thermostats. It allows for the integration of different devices, creating a connected home ecosystem that can be controlled through the alarm system's control panel or a mobile app. Z-Wave is not related to video storage, power backup, or Wi-Fi signal strength.
In a fire alarm system, which type of detector is best suited for detecting smoke particles from a smoldering fire?
A photoelectric smoke detector is more effective at detecting smoke particles from smoldering fires, which produce larger particles that scatter light. Ionization smoke detectors, on the other hand, are more sensitive to flames that produce smaller, invisible combustion particles. Thus, a photoelectric detector is better suited for smoldering fires.
When installing a Closed-Circuit Television (CCTV) camera in a high-security facility, what type of camera would best provide continuous monitoring with a wide field of view?
PTZ cameras are ideal for high-security environments because they allow remote control over the camera’s pan, tilt, and zoom functions, providing a wide field of view and continuous coverage. Operators can adjust the camera’s focus, following moving subjects and capturing different areas as needed. Dome and bullet cameras are fixed or have limited movement capabilities compared to PTZ.
