1

What are the three parts of fire protection.

1.) Detection
2.) Suppression
3.) Containment

2

When was the first smoke detector manufactured (for commercial use)?

1960

3

What was/is the main purpose of fire alarm systems?

Life safety of occupants.

4

What is a proprietary system?

A system that only protects the buildings in which they own.

5

Give the three main functions of a FA control panel.

1.) Receive alarm signals from initiation devices
2.) Send output signals to NAC circuits
3.) Monitor SLC and NAC circuits for integrity.

6

IDC and NAC circuits monitor for integrity how?

They have a slight current with an end of line resistor, when the current doesn't flow, a trouble is reported. In an IDC circuit, if the resistance is no longer seen because of a short, an alarm is reported.

7

How far from the ceiling must wall-mounted heats be mounted?

Between 4" and 12". No less than 4, no more than 12.

8

What is the difference between proprietary and remote monitoring stations?

Proprietary are only buildings owned by the same owner.
Remote is a third-party monitor.

9

A device with inputs and outputs that also monitors for troubles is a basic description of ____.

A fire alarm control panel.

10

What does a trouble indicate?

That system integrity is poor. i/e ground fault, open connection, removed device, etc.

11

Where are trouble signals generated?

At the FACP. (Control Panel)

12

Which of the fire alarm circuit types is used to poll devices?

SLC

13

Why doesn't the slight current for monitoring a NAC circuit operate the horns/strobes/etc?

Because when in alarm, the polarity reverses, and the devices are made to operate only on reverse polarity.

14

What is the lowest temperature we are permitted to install FA equipment in?

32 Degrees Farenheit

15

Why is t-tapping not allowed on IDC or NAC circuits?

Because if a t-tapped device is removed or disconnected, the EOL resistor is still seen by the control panel and no trouble signal is given.

16

What is special about class A fire alarm circuits?

They require redundant return paths for single-break monitoring.

17

What type of circuits are door magnets considered?

Class D
