    摘要: Upon sensing an excessive temperature in a plenum supplying secondary air to a mixing box, a thermostatic element opens a valve to exhaust air from a pneumatic actuator for opening a normally closed secondary air damper. This action permits the damper to close and so prevent flow of secondary air from the plenum into the mixing box. The control may be tested by applying auxiliary heat to the thermostatic element. The control may be made to prevent spread of smoke by making the application of heat to the thermostatic element responsive to a smoke detector.

    摘要: A reciprocating pneumatic actuator moves the damper of an air diffuser between open and closed positions and is automatically vented to atmosphere if fire or high heat occurs in the vicinity of the diffuser. When the actuator is vented, the return spring of the actuator snaps the damper to its closed position. A heat responsive latch automatically holds the damper in its closed position and prevents the damper from dropping open in the event the return spring is weakened by heat.

    摘要: A controller for at least one damper maintains a constant volume rate of flow of air through a duct into a controlled space for a given condition in the controlled space. The dual reset controller resets the volume rate of flow as functions of two sensed conditions.
