Question 1

Purpose of a fire alarm panel?

Answer 1

Provides power to the system monitoring Input and controls outputs through various circuits

Question 2

Identify the most correct definition for the term “IDC”?

Answer 2

Non-addresses Initiating Device Circuit

Question 3

A circuit in which audiable and visual alarm devices are wired?

Answer 3

A circuit to which automatic or manual initiating devices are connected when a signal received does not identify the individual device operated

Question 4

Main purpose of a fire alarm system?

Answer 4

illiminate casualties or injuries to occupants

Question 5

Electro magnetic door contacts are connected to which circuit?

Answer 5

Ancillary Circuit

Question 6

Identify the correct fire alarm control panel response for signal circuit ground fault

Answer 6

Trouble

Question 7

Identify the correct definition for the term “NAC”

Answer 7

Notification Appliance Circuit

Question 8

Identify the operation of residential smoke detector upon detection of smoke (assume detector installed per code requirements)

Answer 8

When one detector goes into alarm condition it sends a 9V signal to through the traveller and signals the other devices to generate an alarm

Question 9

Who carries out verification?

Answer 9

3rd party

Question 10

Heat detectors can be installed using pigtail and wiring connections to make installation easier T or F

Answer 10

False

Question 11

Wet sprinkler system, if one is activated all heads will go off T or F

Answer 11

False

Question 12

When laying out the fire alarm in a commercial installation the OBC is the only guideline T or F

Answer 12

False (CEC as well)

Question 13

Where are EOL (End of Line) resistors located in a class B circuit?

Answer 13

After the final device out in the field

Question 14

For Diagram Class A or Class B…
(State the difference between classes so you know!)

Answer 14

Class B: 2 wires in the field
Class A: 4 wires, the other 2 come back to the panel (in a separate conduit or raceway)

Question 15

What is a supervisory circuit fault?

Answer 15

Condition in which the device supervised by a fire alarm system is moved from its normal state such as would be the case when you close a normally open sprinkler valve.

Question 16

Annunciator- Shall be installed only in a fire alarm control panel T or F

Answer 16

False

Question 17

Annunciator- Shall be installed only at the main entrance of a building and communication lines shall be supervised T or F

Answer 17

True

Question 18

Identify overcurrent disconnect device of a fire alarm?

Answer 18

Red and locked in closed position

Question 19

Identify the term “zone”

Answer 19

Area reserved by detectors
And; designated area of a building

Question 20

Sprinkler heads use a glass tube to prevent water from flowing, the glass ball with an orange liquid will shatter at what temperature?

Answer 20

57°c

Question 21

A Two-Stage Fire Alarm System has:

Answer 21

Both a Cautionary Alarm state at the panel and a Full Alarm state which requires a Supervisor to activate at the source of the Cautionary Alarm (ex. a pull station) Full Alarm will also sound if no action is taken within 5 mins of Cautionary Alarm. (The idea is that a supervisor would go to the device, check to see if it’s a false alarm, and either activate or deactivate the Full Alarm based on what’s there)

Question 22

Electrical supervision of the system wiring shall be provided to
the following items……

Answer 22

(1) Manual Pull Stations
(2) Fire Detectors
(3) Supervisory devices for water based fire protection systems
(4) Audible Signal Devices
(5) Visual Signal devices
(6) Voice Communication Equipment
(7) Emergency telephone handsets
(8) Primary and emergency power supplies
(9) Annunciators
(10) Display and controls at the CACF
(11) Engine driven generators if used
