A modular surface mounted electric strike system is provided. The system comprises a universal base plate having first and second sides, each having first and second mounting points. Each electric strike module includes a header, a keeper assembly, and an actuator assembly configured for moving between a keeper blocking mode and a second mode. When the first and second latches are separated a first distance, the first and second electric strike modules are attached to the first mounting locations on the respective first and second sides of the base plate. When the first and second latches are separated a second distance, the first electric strike module is attached to the second mounting location on either the first or second sides of the base plate, and the second electric strike module is attached to the second mounting location on the other of the first or second side of the base plate.

A surface mounted electric strike for selectively retaining a door latch of a door is provided. The electric strike comprises a housing mounted to a surface of the door frame, wherein the housing defines a cavity configured for receiving the door latch. A keeper is mounted within the housing and movable between a latched position and an unlatched position. The keeper includes a keeper body portion and an extended lobe portion having a terminal end. An actuating assembly is configured for moving between a first mode and a second mode, wherein when the actuating assembly is in the first mode the keeper is prevented from moving toward the unlatched position, and wherein when the actuating assembly is in the second mode the keeper is permitted to move toward the unlatched position.

The electric strike can have a housing having an internal face receivable against a receiving face of a door frame, an external strike face, a socket recessed into the strike face along a socket axis normal to the receiving face of the door frame, for receiving a male locking member retractably mounted to a door, the male locking member also being moveable transversally to the socket axis, along a horizontal escape path, by opening the door, the electric strike further having a keeper pivotally mounted around a pivot axis between a closed configuration and an open configuration, the pivot axis parallel to the socket axis and offset from the escape path on a first side of the socket, inside the housing, the keeper having a gate member forming a restraining wall of the socket blocking the escape path when in the closed configuration, and a distal end.

An exemplary method generally relates to operating an access control device including a motor, a locking member, and a target component operably connected with the locking member. The motor may be operated to drive the locking member in a first direction from an initial position toward a desired position. When the locking member is blocked from moving beyond a blockage position, a target location of the target component is detected. The motor may then be operated to drive the locking member in a second direction opposite the first direction. The motor may then be operated to drive the locking member in the first direction toward the blockage position while monitoring the location of the target component. As the target component reaches the target location, the motor is supplied with a boost current to drive the locking member beyond the blockage position and toward the desired position.

An exemplary rotation converter includes an input component, an output component, and an intermediate component engaged between the input component and the output component. The input component is rotatable from an input component home position in each of a first direction and an opposite second direction. The intermediate component is configured to move to an actuated position in response to rotation of the input component in either direction, and to rotate the output component in an actuating direction as the intermediate component moves to the actuated position.

A system may be configured to detect an emergency condition at a premises; dispatch one or more autonomous drones to a location associated with the emergency condition; receive from the one or more autonomous drones, sensor data associated with the emergency condition; generate, based on the sensor data, a plan identifying an evacuation route for safely evacuating the premises; and transmit an instruction that causes the one or more autonomous drones to indicate, to one or more persons in a vicinity of the emergency condition, the evacuation route. The system may further detect, based on the sensor data, one or more safe areas in the premises, and the evacuation route may pass through at least one of the one or more safe areas.

An exemplary trim assembly comprises a housing assembly, a cam rotatably mounted to the housing assembly, a lift finger slidably mounted in the housing assembly such that the cam is operable to linearly drive the lift finger between a deactuated position and an actuated position, and a locking mechanism operable to selectively retain the lift finger in the deactuated position. The locking mechanism includes an interface member engaged with the lift finger such that movement of the lift finger moves the interface member between a home position and an offset position, a blocking member operable to selectively prevent movement of the interface member from the home position, and a driver configured to move the blocking member between a blocking position and an unblocking position to thereby lock and unlock the trim assembly.

An exemplary electronic actuator assembly is configured for use with a pushbar assembly having a drive assembly operable to retract a latchbolt, and includes an input shaft, a motor, and a boost spring. The motor has a retracting state in which the motor drives the input shaft from a proximal position to a distal position, a holding state in which the motor exerts a holding force to retain the input shaft in the distal position, and a releasing state in which the motor exerts a residual force that resists movement of the input shaft. The boost spring exerts a boost force urging the input shaft in the proximal direction to at least partially counteract the residual force.

An electric door lock and monitoring system and method of use provides for intelligent control of a door lock, including fire alarm control and monitoring. The system employs location-based rules to facilitate code compliance, such that the system controls the door lock at least in part based on a selected subset of the location-based rules data, the subset of location-based rules data being automatically selected by the processor at least in part based on data indicative of a geographic location of the electronic door lock. The system, also employs spoken word alarms increase in frequency and/or in sound pitch over time to portray increased urgency.

An electronic cathode lock includes a base formed with an opening that is communicated with an accommodating chamber in the base. In the accommodating chamber, two retaining units are provided symmetrically at two sides of the opening, and two driving units are provided corresponding to the retaining units. The two driving units are configured to position the retaining units to overlap the opening, or make the retaining unit move away from the opening. Thereby, the electronic cathode lock limits a latch in the accommodating chamber or makes the latch get out of the accommodating chamber. Such electronic unlocking of the electronic cathode lock is configured to work with a mechanical lock, thereby electronizing the mechanical lock.
