  1. What is the minimum clearance typically required between a fire damper sleeve and the surrounding construction?

    Answer: 1/8 inch on all sides to allow for thermal expansion

    A small clearance of approximately 1/8 inch is required around the damper sleeve to allow for thermal expansion when exposed to heat.

  2. Which NFPA standard governs the installation of fire dampers and smoke dampers in HVAC systems?

    Answer: NFPA 90A

    NFPA 90A, Standard for the Installation of Air-Conditioning and Ventilating Systems, provides requirements for fire and smoke damper installation.

  3. A smoke damper is required to close when which condition is detected?

    Answer: Smoke is present in the duct or space

    Smoke dampers are designed to close upon detection of smoke in the duct or associated space to prevent smoke migration.

  4. After a fire damper has been triggered by its fusible link, what must be done before returning the damper to service?

    Answer: Replace the fusible link and reset the damper blades

    Once a fusible link melts and the damper closes, a new fusible link must be installed and the damper manually reset before the system is functional again.

  5. What is the purpose of an access door installed near a fire or smoke damper?

    Answer: To provide inspection and manual reset access to the damper

    Access doors near dampers allow qualified personnel to inspect, test, and manually reset the damper as required by code.

  6. Which type of actuator allows a smoke damper to be remotely controlled and monitored by a building automation system?

    Answer: Electric modulating actuator

    Electric modulating actuators enable remote operation, position feedback, and integration with building automation or fire alarm control systems.

  7. When a combination fire/smoke damper is installed in a smoke control system, it must close on both smoke detection AND at what temperature?

    Answer: 165°F

    Combination fire/smoke dampers are rated to close at 165°F via their fusible link in addition to closing upon smoke detection.
