PSP Intrusion Detection Systems

Question 1

What is the primary difference between a 'point' intrusion detection sensor and a 'line' or 'volumetric' sensor?

Accepted Answer

Point sensors protect a single specific location (door/window), while volumetric sensors cover an entire area or zone

Answer

Point sensors are more expensive than volumetric sensors

Answer

Point sensors require a wired connection while volumetric sensors are wireless

Answer

Point sensors detect motion only while volumetric sensors detect heat

Question 2

Which type of motion detector is MOST resistant to false alarms caused by HVAC air currents, heat vents, and changes in ambient temperature?

Accepted Answer

Dual-technology (PIR + microwave) detector

Answer

Passive infrared (PIR) detector

Answer

Microwave (Doppler) detector

Answer

Ultrasonic detector

Question 3

In an alarm system, what does a 'supervisory circuit' monitor?

Accepted Answer

The integrity of wiring and sensors to detect tampering or sabotage

Answer

The identity of personnel arming and disarming the system

Answer

The battery backup level of the control panel

Answer

The response time of the monitoring center

Question 4

Under UL 2050 standards for central station alarm monitoring, what is the maximum response time for a central station to call the subscriber after receiving an intrusion alarm signal?

Accepted Answer

90 seconds

Answer

30 seconds

Answer

5 minutes

Answer

10 minutes

Question 5

What is a 'shunt' in the context of an intrusion detection system, and when is it used?

Accepted Answer

A bypass of a specific sensor zone to allow legitimate access without triggering an alarm

Answer

An emergency override that disables the entire alarm system

Answer

A redundant communication path between the panel and monitoring center

Answer

A metal shield protecting alarm wiring from electromagnetic interference

Question 6

Which IDS sensor is specifically designed to detect an attempt to break through walls, floors, or ceilings rather than entering through doors or windows?

Accepted Answer

Seismic/vibration sensor

Answer

Glass break detector

Answer

Passive infrared motion detector

Answer

Photoelectric beam sensor
