S95 FACP and Signal Types 3

Question 1

What is a key operational advantage of a Class A initiating device circuit over a Class B circuit?

Accepted Answer

It can still receive alarm signals after a single open-circuit fault occurs

Answer

Class A circuits loop back to the FACP, providing an alternate signal path that allows the panel to receive signals even when one wire segment is broken.

Question 2

Which initiating device circuit style continues to receive alarm signals from devices even after a single wire break?

Accepted Answer

Class A

Answer

Class A wiring returns to the FACP through a second path, so a single open fault does not disable the remaining devices on the circuit.

Question 3

In fire alarm system terminology, a 'zone' is best defined as:

Accepted Answer

A geographic area or defined function that is annunciated as a single unit at the FACP

Answer

A zone groups initiating devices in a specific area or function so the FACP can identify the general location of an alarm condition.

Question 4

What is the primary function of a remote annunciator panel connected to an FACP?

Accepted Answer

To provide visual indication of system status at a location remote from the FACP

Answer

A remote annunciator mirrors the FACP's zone status indicators at a convenient location, such as the main lobby, for use by firefighters and building staff.

Question 5

In an addressable fire alarm system, each initiating device is assigned:

Accepted Answer

A unique address allowing individual identification at the FACP

Answer

Addressable systems assign a unique address to every device, enabling the FACP to identify exactly which device initiated an alarm or trouble condition.
