An exemplary modular hold-open device is configured for use with a door closer comprising a body, a pinion rotatably mounted to the body, and an armature connected with the pinion. The modular hold-open device is configured to be mounted to the door closer, to selectively prevent rotation of the pinion by exerting on the pinion a resistive torque in a door-opening direction, and to cease exerting the resistive torque in response to a door-closing torque on the pinion exceeding a threshold torque to thereby permit rotation of the pinion in the door-closing direction.

Modular hold-open device for door closers

A door closer system is provided that includes a motor, a spring, a reduction gear set, and a rack and a pinion mechanism. The spring and pinion may be coupled to the rack, and the pinion may be selectively coupled to the gear set. The motor may be selectively mechanically coupled to the gear set. The pinion may rotate in a first direction via the rack as the spring is compressed in a second direction opposite the first direction as the spring is expanded. The motor is operable to rotate and act upon the pinion through the gear set, thereby rotating the pinion in the second direction and assist the spring in closing the door.

Modular add-on devices for door closers

One embodiment relates to an exit device assembly. The exit device assembly includes a center case, a push pad movably mounted on the center case, and a mechanical case coupled to the center case, wherein the exit device includes an opening. The assembly also includes a sensor aligned with the opening, wherein the sensor is structured to detect a user from a distance through the opening and to generate an output signal in response to detecting the user. The assembly also includes a latch and a latch actuator. The assembly also includes a controller in communication with the sensor and the latch actuator, wherein the controller is structured to transmit an actuating signal in response to receiving the output signal from the sensor, wherein the latch actuator is configured to move the latch from the locked position to the unlocked position in response to the actuating signal.

User sensing exit device

An exit device according to one embodiment includes a plurality of sensors and an electronic dogging mechanism. The exit device is configured to locally analyze sensor data to determine the security state of the exit device, report data to a management system via a wireless communication channel established between the exit device and the management system, and receive and process instructions to perform an electronic dogging operation.

Exit device systems and methods

A door closer system is provided that includes a motor, a spring, a reduction gear set, and a rack and a pinion mechanism. The spring and pinion may be coupled to the rack, and the pinion may be selectively coupled to the gear set. The motor may be selectively mechanically coupled to the gear set. The pinion may rotate in a first direction via the rack as the spring is compressed in a second direction opposite the first direction as the spring is expanded. The motor is operable to rotate and act upon the pinion through the gear set, thereby rotating the pinion in the second pinion direction and assist the spring in closing the door.

An adjustable length cable system that can be used in association with transmission of an axial pulling force. The cable system, which can be concealed within and/or behind a structure such as, for example, within an interior region of an entryway device, can accommodate adjustments in the axial lengths of a core wire and a conduit system of the cable system. The core wire can extend through, as well as beyond, the conduit system, and be connected to end fittings and/or connectors that can be used to transmit a pulling force to and/or from one or more components. In some embodiments, the conduit system can include an inner conduit telescopically coupled to an outer conduit such that the axial length of the conduit system is adjustable. Further, the relative axial positions of the inner and outer conduits may be retained by activation of a conduit locking device.
