Q

Difference between an impeded egress zone and a contained use area?

A

an impeded egress zone is a supervised area where occupants have free movement but require the release of security doors. ex - hospital

Q

No major occupancy of Group F shall be contained within a building with any occupancy classified as GROUP __,__ or __.

A

A, B or C

20
Q

Can you perform vehicle repairs in a storage garage?

A

no provision for the repair or servicing of motor vehicles

21
Q

What is a conventional fire alarm system?

A

known as a hardwired system and is the most common type of fire alarm system
uses two wire circuits terminating with an end-of-line resistor

22
Q

What is an addressable fire alarm system?

A

known as a distributed system or multiplex, it has the ability to identify each active fire alarm field device by way of an address.
uses data communication links (DCL’s) and addressable devices like input devices, output devices, annunciators and remote transponders

23
Q

What is a DCL

A

it is configured as a loop connecting all addressable fire alarm field devices, it must return on a different path back to the control unit

24
Q

What are the 3 types of isolators?

A

Data Communication Links (DCL’s)
Signal Circuits Isolators
Power Buss Isolators

25
Q

What is a fault isolation module?

A

a circuit device that monitors the communication line between isolators, in the event of a short circuit it disconnects the bad segment and transmits the signal through an alternate path

26
Q

Where are fault isolation modules required?

A

one at the last wired location prior to leaving the fire zone and one at the first wire location entering the next fire zone

27
Q

What is a class A circuit?

A

designed so all devices are interconnected by means of the wiring returning to the fire alarm control panel instead of an end-of-line resistor. When a device is activated on a circuit the rest of the system continues to function

28
Q

What is a Class B circuit?

A

Most common type of wiring, it uses an end-of-line resistor after the last device on a circuit. When a device is activated all the other devices on the circuit will not operate as it inhibits the functionality of the fire alarm system.

29
Q

A transformer and a rectifier are used to convert ____ to _______.

A

120 volt AC to 24 volt DC

30
Q

Alarm signal circuits include audible/visual signals, circuits are electrically supervised but use a supervisory current blocking component in the device known as a ________.

A

Diode

31
Q

One-way communication means issuing prerecorded _________ ______________ to the building occupants

A

voice instructions

32
Q

Two-way communication refers to an__________ ____________ ___________ , that allows two-way communication between a firefighter and the occupant

A

emergency telephone system

33
Q

Emergency telephone circuits are typically class __ Circuits, they are electrically supervised against ground faults/opens and will produce a trouble signal

A

Class B circuit

34
Q

Speaker circuits are only designed for __ volt or __ volt AC.

A

25 volt or 70 volt

35
Q

What are examples of ancillary devices that would be activated in the event of an alarm condition?

A

door holder release, maglock release, elevator recall, fan startup, fan shutdown, damper operation

36
Q

Is the wiring to ancillary devices required to be supervised?

A

NO, not a code requirement

37
Q

Ancillary devices may be controlled through the fire alarm panel by ________.

A

relays

38
Q

A control unit must transmit 3 signals to off-site monitoring

A

1) alarm
2) supervisory
3) trouble

39
Q

Fire alarm system devices connected in an electrically supervised circuit shall be connected so that the removal or disconnection of any device shall cause a _______ signal to be initiated.

A

trouble

40
Q

Separation of wiring circuits, having a minimum separation of ___mm when installed vertically and having a minimum separation of ____mm when installed horizontally.

A

300mm vertically and 1200 mm horizontally

41
Q

A fire alarm system shall consist of at least the following interconnected devices…

A

1) a control unit
2) a manual pull station
3) audible signal device

42
Q

What do FACP and CACF each stand for?

A

Fire Alarm Control Panel (FACP)
Central Alarm Control Facility (CACF)

43
Q

Single Stage vs Two Stage

A

Single-stage fire alarm systems require immediate evacuation upon an alarm while the two-stage systems sound an ALERT SIGNAL first, after a period of time then it will go into full evacuation

44
Q

Alert signal vs. Alarm signal

A

An alert signal is an audible signal advising occupants to evacuate while an alarm signal does the same thing except the audible signal is transmitted to a zone or zones

45
Q

Define flame-spread rating

A

the extent a material or an assembly of materials can withstand the spread of flame

46
Q

An arena-type building intended for occasional use for trade shows shall be classified as a Group __, Division __ occupancy.

A

Group A Division 3
