f. opening and closing reports
g. partition
h. swinger shutdown
i. walk test/chime

A

a. automatic arming - arms burglar alarm system, if not already (ex: employee forgets)
b. automatic bypass - bypasses interior zones when system armed
c. automatic testing - sends signal to central monitor station at interval - checks in
d. force arming - bypasses zones that aren’t ready when system armed
e. lock out - prevents others from reprogramming a system
f. opening and closing reports - sends signals to monitor when system is disarmed (arms and disarms)
g. partition - assigns zones to specific keypads.
h. swinger shutdown - bypasses zones that repeatedly go into alarm
i. walk test/chime - keypad sounder chirps when zone is violated

Q

Describe the difference between a duress code and a keypad panic.

A

Duress sends special signal (no audio alarm) to monitor

Panic programmed buttons are used as indications - needs someone at keypad.

21
Q

How does a microwave detector work?

A

It transmits microwave signals and analyzes signals that are reflected back to the unit.

22
Q

How does an audio glassbreak detector work?

A

If the sound of breaking glass frequency is detected, an alarm signal is generated. It has a built in microphone.

23
Q

What is the range of most glassbreak detector

A

15 to 30 feet

24
Q

Ca you mount a standard glassbreak detector above the window that is being protected?

A

NO - unless it is stated on the detector

25
Q

What items could interfere with the operation of an audio glassbreak detector

A

curtains or blinds, line of sight

26
Q

List three sources of false alarms for audio glassbreak detector

A

hand clapping, jingling keys, clanging pans

27
Q

How do dual technology audio glassbreaks reduce false alarms?

A

It requires two frequencies to trigger alarm

28
Q

Why are mechanical shock sensors more prone to false alarms?

A

lack of circuitry to analyze shocks

29
Q

Were are shock sensors mounted?

A

depends on the type used and intended application - glass or window frame

30
Q

What is the operating principle of photoelectric beam detectors?

A

transmits invisible, pulsing beam of light from one unit and receives at another.

31
Q

What are the three main types of photoelectric beam detectors?

A

single, dual, reflective

32
Q

Give an example of where you would have to use a reflective beam detector.

A

indoor entry chimes - can only get wire to one side

33
Q

How can you reduce the occurrences of false alarms when using photoelectric beam detectors?

A

dual beam

34
Q

Can smoke detectors or heat detectors be installed on any control panel?

A

NO - exception: the control panel MUST BE properly listed for fire alarm use.

Q

How are addressable expansion devices typically connect to the control panel?

A

single two wire circuit

45
Q

Is T-tapping the addressable circuits allowed? If so, how is supervision of the circuit maintained?

A

Yes, and by the control panel

46
Q

Are standalone wireless receivers required to be made by the same manufacturer as the alarm panel.

A

No, but this one was circled, so not sure if correct

47
Q

What are the advantages when using a supervised transmitter vs. an unsupervised model?

A

It reports to receiver when battery power is getting low
