What is the purpose of an end-of-line resistor in a fire alarm circuit?
Answer: To supervise the wiring and detect breaks or faults
An end-of-line resistor provides circuit supervision by maintaining a specific electrical resistance. If the wiring is cut or broken, the resistance changes and the panel detects a trouble condition. This ensures wiring faults are discovered before a fire occurs.
In a zoned fire alarm system, what does each zone represent?
Answer: A defined area or floor of the building
In a zoned fire alarm system, each zone represents a defined area such as a floor, wing, or section of the building. When an alarm activates, the panel indicates which zone is affected, helping responders locate the fire quickly rather than searching the entire building.
What is the minimum required sound level for fire alarm notification appliances (horns/strobes) in sleeping areas?
Answer: 75 decibels at the pillow
Fire alarm notification appliances in sleeping areas must produce a minimum of 75 decibels at the pillow level to ensure sleeping occupants are awakened. This higher threshold accounts for the reduced awareness of sleeping persons compared to those who are awake.
What type of fire alarm signal is used to alert building staff without alarming all occupants?
Answer: Pre-signal or presignal alarm
A pre-signal (presignal) alarm notifies trained staff first before sounding the general alarm throughout the building. This allows staff to investigate and verify a fire condition before initiating a full building evacuation, which is especially important in shelters where mass evacuation could cause panic.
How should a Fireguard test a manual pull station during a scheduled fire drill?
Answer: Use a test key or notify the monitoring company to place the system in test mode first
Before testing any alarm device, the monitoring company must be notified and the system placed in test mode to prevent a false dispatch of the fire department. A test key may be used to activate the pull station. This prevents unnecessary emergency responses while still verifying device function.
What is the difference between an ionization and a photoelectric smoke detector?
Answer: Ionization detects flaming fires faster; photoelectric detects smoldering fires faster
Ionization detectors respond faster to fast-flaming fires with small smoke particles, while photoelectric detectors respond faster to slow-smoldering fires that produce larger smoke particles. Understanding this difference helps in selecting the right detector for each area of a shelter.
