摘要： The narrow band scanning RF receiver (12) includes a ph ase-locked loop radio frequency stage having a reference oscillator (38) for receiving a radio frequency signal. The radio frequency stage has a frequency which may be selected by a controller via a selectable frequency signal supplied to the reference oscillator (38). The controller tests for the presence of a legitimate radio frequency signal and also temporarily inhibits the tuned radio frequency stage when changing from a first selected frequency to a second selected frequency. The receiver (12) produces an output for controlling an electric motor (100) for operating a barrier.

摘要： A controller for controlling a motor and other functions in a commercial door or barrier operator is described. The controller includes a unique motor start circuit for starting an AC motor which employs two dual-pole-dual-throw (DPDT) relays for activating the start coil in combination with a single triac for activating the main coil of the motor, eliminating dv/dt sensitivity. A motor start control for a door or barrier operator includes a speed governor integrated onto the controller for detecting when to shut off AC power to the start coil in a single phase motor. The integrated speed governor uses an RPM sensor for detecting the speed of the operator's limit shaft coupled to software run by the processor. Switches for operating open, close, stop and learn functions are located on the controller to facilitate installation, maintenance and programming by a service provider at the door operator. In addition, a cycle counter provides a warning when the number of barrier movements equals a predetermined, programmable number of movements.

摘要： A fire door opener or operator (10) according to the invention includes a DC brake solenoid (632) coupled to an AC motor drive system (12) with an inline gear reducer. If AC power is lost, the brake can be controlled by an electronically controlled descent device and the battery backup power. If the brake is disengaged, the door (20) will drop by overcoming the internal inertia and friction in the inline gear reducer. A method for electronically controlling the descent speed of a fire door with or without AC power or motor control is also described. Speed of descent is controlled electronically by measuring the descent speed of the fire door (20) at its limit shaft and electrically modulating the brake engagement using the DC solenoid (632).
