Static fireplace dampers are sometimes gravity-assisted and designed for placement in HVAC systems the place the fans turn off within the occasion of fire or smoke.
How to Use the Map
The alternative between Fire Damper Type A, B, or C largely depends on the specific wants of the building and the HVAC system in place, and requires considerate consideration. Type B fireplace dampers provide a decrease stress drop by eradicating the blade stack from the air stream. With the blade stack out of the air stream, the air can move through simply. Shorter peak ducts (typically lower than 12") or excessive velocity ducts benefit greatly from Type B fireplace dampers. Shorter ducts endure from a better proportion of free area blocked by the blade stack in a Type A fireplace damper. Type B fire dampers remedy the problem by removing them from the air stream.

Simply put, fireplace dampers are triggered by fireplace, smoke dampers are triggered by smoke, and combination dampers are triggered by both hearth or smoke.

Figure 6 shows the same smoke damper as in Figure 4 with an added relay to override the damper open. By shorting hot power to terminal 3 of the actuator, it'll drive open. While not at all times needed, a contact opens to disconnect the sign terminal on the potentiometer. The potentiometer has a various sign of from 2 to 10VDC that goes to terminal three, the sign enter.
