A duct smoke detector in an HVAC system is designed to:
Answer: Detect smoke in air ducts and shut down the HVAC system to prevent smoke spread
Duct smoke detectors sense smoke within HVAC ductwork and automatically shut down the air handling unit to prevent smoke from being distributed throughout the building.
What is the purpose of a manual fire alarm pull station?
Answer: To allow any person to manually activate the fire alarm system upon discovering a fire
Manual pull stations allow any building occupant who discovers a fire to immediately activate the building's fire alarm system, alerting all occupants and notifying FDNY via central station monitoring.
A 'pre-action' sprinkler system differs from a standard wet pipe system in that it:
Answer: Requires both a detector activation AND a sprinkler head to open before water flows
Pre-action systems have a two-step activation: a fire detection device must activate to open a control valve, AND individual sprinkler heads must also open from heat before water flows to that head.
The central station monitoring company's role in fire alarm response is to:
Answer: Receive alarm signals from the building and immediately notify FDNY
The central station monitoring company receives alarm, supervisory, and trouble signals from the building's fire alarm system and immediately transmits fire alarms to FDNY for response.
Heat detectors are preferred over smoke detectors in which type of building area?
Answer: Kitchens, cooking areas, and other locations where smoke is normally present
Heat detectors are used in kitchens and areas where cooking fumes or steam would cause frequent false alarms with smoke detectors, while still providing fire detection.
When the fire alarm system is placed in test mode for annual inspection, the FLSD must:
Answer: Notify the central station monitoring company so FDNY is not dispatched for test signals
Before any fire alarm system testing, the FLSD must notify the central monitoring station so they can place the system in test mode, preventing test signals from dispatching FDNY unnecessarily.
