S95 Fire Alarm System Components 5

Question 1

How does an aspirating smoke detection (ASD) system detect smoke?

Accepted Answer

Drawing air samples through a pipe network to a central detection unit

Answer

ASD systems use a fan to pull air through small-bore sampling pipes into a centralized detector, allowing very early detection of trace smoke concentrations.

Question 2

Which detector type is most appropriate for protecting large open spaces such as warehouses, atriums, or aircraft hangars?

Accepted Answer

Linear beam smoke detector

Answer

Linear beam detectors project a light beam across the protected space and can monitor large areas that would require impractical numbers of spot-type detectors.

Question 3

In an addressable fire alarm system, what is the purpose of a relay output (control) module?

Accepted Answer

To control ancillary equipment such as door holders, dampers, and fan shutdown

Answer

A control module uses the signaling line circuit to deliver a switched output that can operate relay-driven equipment such as door release mechanisms or HVAC shutdown contactors.

Question 4

In an addressable fire alarm system, what is the primary function of a monitor module?

Accepted Answer

To supervise and report the status of conventional non-addressable devices on the SLC

Answer

A monitor module connects conventional devices (such as 4-wire smoke detectors or pull stations) to the addressable SLC, giving each zone a unique address on the system.

Question 5

Carbon monoxide (CO) detectors installed as part of a fire alarm system must be:

Accepted Answer

Listed for use with the specific fire alarm control panel to which they are connected

Answer

CO detectors used with fire alarm systems must be listed (typically UL 2075) and compatible with the specific FACP to ensure proper signal processing and system integration.
