I've been trying to find answers for those questions for few day already and can not find them anywhere. If someone can help me please I will be grateful

 

1.What are the four parts to an intruder alarm system?

2.Describe how you would measure and test an end of line circuit if the circuit was suspected of having a fault.

3.Strobes are often found to be fitted to external sounders. They tend to be wired independent of the siren so they can be powered and energised separately. What could be the reason for this?

4.The power supply unit (PSU) carries out a number of tasks.

 

a)    What is the actual value of the regulated supply voltage that it provides to the system?

 

b)    What would be the influence on that voltage at the detection devices that are powered by that supply if the detectors were to be installed at an extended distance from the control equipment?

 

5.The modern day PIR incorporates a multitude of features and is available in many different versions. Give two examples of these features.
