Study Notes

Fire Alarm Systems and Equipment

  • Dwelling fire warning equipment primarily aims for life safety.
  • Available single-station smoke alarms for dwellings began in the 1970s.
  • NFPA 72, Chapter 29 covers requirements for areas like apartments.
  • Heat alarms must be installed on the bottoms of beams or joists in ceilings.
  • Smoke alarms are required for areas exceeding 1,000 square feet.

Smoke and Heat Detectors

  • Multiple-station alarms activate interconnected devices.
  • Actuation of smoke alarms does not trigger alarms in other dwellings or the building fire alarm system.
  • Single-station and multiple-station smoke alarms are not suitable for office buildings, only household use.
  • Smoke alarms can operate between 40°F and 100°F; heat detectors are preferred in garages and crawl spaces.
  • Wall-mounted heat detectors should be 4 to 12 inches from the ceiling.

Installation and Specifications

  • A maximum of 12 unmonitored smoke alarms can be interlinked.
  • Smoke detectors must be within 3 feet of peaked ceilings and 4 inches from walls.
  • NFPA 72 mandates smoke detection as the primary fire detection means in dwellings.
  • Dwellings require a fire alarm signal of at least 75 dBA at the pillow in sleeping rooms.

Notification and Alarm Features

  • Visible notification appliances must be over 24 inches from ceilings to awaken sleepers.
  • A new two-story dwelling with a basement needs at least 6 smoke alarms.
  • Heat detectors must have a spacing of at least 50 feet and function at temperatures 25°F above the ambient maximum.

Communication Systems

  • Smoke alarms should be installed within 10-20 feet of cooking appliances or 3 feet from supply diffusers.
  • Carbon monoxide alarms must be in rooms with fossil fuel appliances.
  • Digital alarm communicator systems require a minimum of two communication means.

Historical and Regulatory Context

  • Boston had the first public emergency alarm system operational since 1852.
  • Duct smoke detectors are mandatory when airflow exceeds 2,000 cfm.
  • NFPA 90A outlines the need for detection in HVAC systems of designated airflow capacities.

Testing and Maintenance

  • Central station services should comply with transaction protocols and record retention policies.
  • Devices must be tested and reliable, with central station operators expected to re-transmit alarm signals within 90 seconds.
  • Pathway monitoring frequencies differ for independent systems, with intervals of 6 hours for DACT and 1 hour for IP transmitters.

Fire Detection Technologies

  • Area smoke detectors must not be located less than 3 feet from HVAC components.
  • Heat detection is favored in environments with specific characteristics, such as unheated areas or garages.
  • Combustion produces smoke without flames through pyrolysis, while ionization detectors are more effective for smaller particles.

Specification and Regulation Compliance

  • Fire protection system specifications can detail site-specific requirements and components.
  • The MasterSpec numbering system currently organizes fire protection details under Division 28.
  • Shop drawings typically display routing, device addresses, and schedule for wires and conduits.

Miscellaneous Details

  • Runners for central station services must report every 15 minutes.
  • Smoke alarms or detectors in basements should be installed near stairs.
  • Visual alarm appliances must be installed a minimum of 80 inches above the finished floor.
