A tool for terminating wires to electrical connectors includes an outer body configured to fit with an operator's hand and a first receiving member mounted in the outer body for releasably holding an electrical connector in place within the outer body. A first wire guide slot is located at a first end of the outer body remote from the first receiving member. The first slot is aligned with the first receiving member to align wires located in the first slot with the electrical connector held by the first receiving member.

A modular connector panel has a planar front panel with opposite surfaces. A plurality of panel openings extend through the panel in an aligned array. Support members extend from a surface of the panel and have near ends connected to the panel and remote ends spaced from the panel. Abutments extend laterally from the remote ends of the support members and parallel to the panel, and have abutment surfaces facing the panel. The abutments are arranged in pairs, with each pair being aligned with a panel opening. A connector can be coupled by engaging a pair of abutments and extending into a panel opening.

A modular cable management panel assembly includes a panel, a set of rings mounted on a surface of the panel and a cover coupled to the rings. The rings are spaced along the panel longitudinal axis and have openings extending laterally through them. The cover is movable between a closed position extending over and closing the ring openings and an open position spaced from the ring openings to allow cables to pass laterally into and out of the rings. The panel assembly is adaptable for mounting various accessories.

An electronic push retraction exit device includes a support rail, a push rail and a latch mechanism having a latch bolt operably connected to the push rail and movable between latched and unlatched positions. A control circuit in the exit device drives a linear actuator to retract and hold the push rail and the latch bolt in the unlatched position. The linear actuator preferably includes a stepping motor and is connected to the push rail through a lost motion connection allowing the exit device to be mechanically operated without moving the linear actuator. The control circuit preferably includes an electrical adjustment for the retraction distance of the latch bolt and an adjustable relatch timer. The exit device may be operated by a remote switch attached to a control connection, which may be permanently closed to simulate a prior art electrically operated exit device for compatibility with third party control systems.

A drive mechanism for door hardware, such as a pushbar exit device, includes a driver for moving a component of the door hardware, a controller for controlling the operation of the driver, a sensor for detecting motion of the moving component and a spring connected between the driver and the door hardware component. The spring allows the driver to move for a period of time after the component has stopped moving. The controller monitors the sensor and moves the component until the sensor indicates that the driven component has stopped moving. The sensor produces an output signal and the controller detects an inflection point in the output signal when the component stops moving while the driver is still operating.
