10+ Fire Alarm Technician Interview Questions and Answers

Fire alarm systems are designed to detect and alert people about the presence of fire or smoke in a building.

• Fire alarm systems consist of various components such as smoke detectors, heat detectors, fire alarm control panels, and notification devices.

• Smoke detectors are designed to sense the presence of smoke particles in the air and trigger an alarm.

• Heat detectors are used to detect rapid increases in temperature and activate the alarm system.

• Fire alarm control panels are th...read more

FM 200 systems are fire suppression systems that use HFC-227ea as the extinguishing agent.

• FM 200 systems are commonly used in areas where water-based fire suppression systems are not suitable, such as data centers and museums.

• HFC-227ea is a clean agent that does not leave residue or damage sensitive equipment.

• FM 200 systems work by reducing the oxygen concentration in the protected area to a level that cannot support combustion.

• These systems are activated automatically by smo...read more

FM-200 extinguishes fire by removing heat and interrupting the chemical reaction.

• FM-200 is a clean agent fire suppression system.

• It works by releasing a colorless and odorless gas into the protected area.

• The gas removes heat from the fire, lowering the temperature below the ignition point.

• FM-200 also interrupts the chemical reaction of the fire, preventing it from spreading.

• It does not leave any residue or damage to the protected area.

• FM-200 is commonly used in data centers, ...read more

A fire alarm is a system that detects and alerts people to the presence of fire, allowing for timely evacuation and fire suppression.

• Fire alarms work by detecting smoke, heat, or flames using sensors.

• When the sensors detect a potential fire, they send a signal to the control panel.

• The control panel then activates the alarm devices, such as sirens, strobe lights, and voice evacuation systems.

• Fire alarms may also be connected to a monitoring service that alerts emergency respon...read more

FM-200 replaced Halon as a fire suppression agent.

• FM-200 is a clean, colorless, and environmentally friendly fire suppression agent.

• It is commonly used in areas where water-based fire suppression systems are not suitable.

• FM-200 replaced Halon due to its harmful effects on the ozone layer.

• Halon was widely used as a fire suppression agent but was phased out due to its ozone-depleting properties.

• FM-200 is non-toxic and leaves no residue, making it safe for occupied spaces.

Output and input modules are components of a fire alarm system that allow for communication between devices and the control panel.

• Output modules receive signals from the control panel and activate devices such as horns, strobes, and speakers.

• Input modules receive signals from devices such as smoke detectors and heat sensors and transmit them to the control panel.

• Both modules are essential for the proper functioning of a fire alarm system.

• Examples of output modules include rel...read more

FM 200 is a clean agent fire suppression system commonly used in data centers and other sensitive areas.

• FM 200 is a colorless, odorless gas that is stored in cylinders.

• When discharged, FM 200 quickly fills the protected area and suppresses the fire by removing heat.

• It works by interrupting the chemical chain reaction of the fire.

• FM 200 is non-toxic and safe for occupied spaces.

• After discharge, FM 200 dissipates into the atmosphere without leaving any residue.

• Regular maintenan...read more

FM 200 System is a fire suppression system that uses HFC-227ea as the extinguishing agent.

• FM 200 System is a clean agent fire suppression system.

• It uses HFC-227ea, a colorless and odorless gas, as the extinguishing agent.

• The system is designed to quickly suppress fires in enclosed spaces.

• FM 200 is effective in suppressing Class A, B, and C fires.

• It works by interrupting the chemical chain reaction of fire.

• FM 200 is stored in cylinders and released through a network of pipes a...read more

A fire alarm system is a network of devices that detect and alert people to the presence of fire or smoke.

• Fire alarm systems are designed to quickly detect and respond to fires, helping to save lives and minimize property damage.

• They typically consist of smoke detectors, heat detectors, fire alarm control panels, and notification devices such as sirens or strobe lights.

• When a fire is detected, the system activates the notification devices to alert occupants of the building an...read more

Fire protection refers to measures taken to prevent and minimize the impact of fires in buildings and other structures.

• Fire protection includes the installation of fire alarms, sprinkler systems, and fire extinguishers.

• Regular maintenance and testing of fire protection equipment is essential to ensure it functions properly in case of a fire.

• Fire protection also involves creating and implementing fire safety plans and conducting fire drills to educate occupants on proper evacu...read more
