Abstract: An exit bar has an elongated body for mounting on an exit door. The exit bar incorporates a pair of independent sensors. An infrared beam is generated along the front of the bar. An infrared detector produces a first signal when the beam is interrupted. The first signal results in release of a lock securing the door. If the beam is interrupted for longer than a pre-set time limit, a first alarm sounds. A capacitance sensor produces a second signal when the sensor detects changes of capacitance in the bar as a result of contact or near contact with foreign objects. The second signal also results in release of the lock securing the door. If the capacitance sensor detects a capacitance change for longer than a pre-set time limit, a second alarm sounds.

Abstract: An electromagnetic door lock system employs an on-board microprocessor which is mounted in the housing for the electromagnet. The microprocessor is pre-programmed with possible operating parameters which are then selected at the installation site. In one embodiment, a contact activatable data reader is mounted at the housing to provide various input data for the microprocessor. The microprocessor is also capable of being interrogated to reveal the preset operating parameters and other information, including the identification of individuals requesting to egress through the associated doorway.

Abstract: An exit door security system which employs an electromagnet and armature to lock an exit door comprises an electromagnetic housing and a frame assembly. The housing is pivotally mounted to the frame assembly. An attempt to exit the door causes the housing to pivot to thereby actuate a switch. The lock is automatically released after a pre-established time delay. An alarm at the door may also be actuated by the switch. The electronic circuitry is configured to allow for immediate authorized egress and to implement an immediate safety release of the lock. The lock may be operated in either a normally locked or normally unlocked mode.

Abstract: In a first embodiment, the invention has a casing set in the frame of a door in confronting relationship to the latchbolt-confining housing of the door. A bolt, translatable in the casing, is extended, by a solenoid, and enters the housing to prevent opening of the door. A latchbolt position sensor, in the form of a dual-ended limb, monitors the position of the latchbolt. Upon withdrawal of the latchbolt, from latching closure of the door, the limb actuates a switch to operate a time delay circuit component. When the specified time delay set by the component has run its course, it cuts power to the solenoid. Compression springs withdraw the bolt from the latchbolt-confining housing, to permit the door to open.

Abstract: A time-delayed mechanism obstructs movement of a latchbolt from its latched position to an unlatched position. Linkage coupled to the latchbolt, and manually acutated (by a push pad, or the like), includes an arm which normally pivots, with the manual actuation of the linkage. An initial, limited movement of the linkage activates a switch, and the latter activates a time delay circuit component. The latter component, following a specified time delay, interrupts power to a solenoid. The solenoid, normally powered, has a bar inductively movable therein with a rod joined thereto for coincident movement. An end of the rod carries a roller which intrudes into the pivotal arc of the arm, preventing full pivotable movement thereof. Consequently, the linkage, which is to move the latchbolt to its unlatched position is blocked until the time delay has run its course, whereupon the solenoid is de-energized. With deenergization of the solenoid, the bar, rod and roller are retracted, to permit full pivotal movement of the arm, and movement of the latchbolt to its unlatched position.
Abstract translation: 延时机构阻止闩锁从其锁定位置移动到解锁位置。 连接到闩锁的手动连杆（通过推垫等）手动地连接，包括通过手动致动连杆的通常枢转的臂。 联动装置的初始有限运动激活开关，后者激活时间延迟电路部件。 后一个组件在指定的时间延迟之后中断电磁阀的电源。 通常供电的螺线管具有可在其中感应地移动的杆，其中连接有杆以便重合运动。 杆的端部携带一个进入臂的枢转弧的辊，防止其完全枢转运动。 因此，将闩锁移动到其解锁位置的连杆被阻塞，直到时间延迟已经过去，于是螺线管断电。 通过螺线管的断电，杆，杆和辊缩回，以允许臂的完全枢转运动，以及闩锁的移动到其解锁位置。

Abstract: An electromagnetic lock which mounts at the top of a door frame and magnetically bonds with an armature employs both an ultrasonic sensor and a passive infrared sensor to detect the approach of an individual at the doorway. Both the ultrasonic sensor and the passive infrared detector have fan-shaped sensing regions which are positioned forwardly from the doorway. Upon detection of an individual approaching the doorway, the lock is capable of automatically releasing to allow egress through the doorway.

Abstract: In the system, exits are provided with opening bars and locks. The system has a central post and control boxes. Each control box is associated with an exit and is connected to the central post. Activation of an opening bar initiates the sending of information to the central post by the associated control box. This triggers a first delay To. During this delay, the opening of the exit can be stopped for a further delay Tc. The opening is allowed at the end of the first delay or at the end of the second delay. A third delay Tp can be triggered during the second delay Tc to allow the opening of the exit under question during the third delay Tp and to relock the exit under question at the end of the third delay Tp, by cancelling the effect of the second delay Tc. The system can also operate in the anti-intrusion mode. In particular, it can be used in stores or public establishments of medium area.

Abstract: A magnetic door breakaway system for remote unlocking of doors and apertures. An electromagnet (80), and armature (82) are mounted within a doorframe. Within either the magnet or armature are depressions (220) and (222) in one member and lands (206) and (208) in the other. In the preferred embodiment, the armature is movably affixed to the top of the doorframe and with energizing of the electromagnet, the lands mate with the depressions, making movement of the door impossible. In an emergency situation, the magnet is de-energized, the two members separate, and the door may open freely.In an alternative embodiment, an electromagnet (304) is connected to a plunger (310) which is received within the striker plate (320).

Abstract: Apparatus for securing an emergency exit door includes a bolt for engaging a keeper, a dogging mechanism for dogging the bolt and a fluid throttling device disposed between the bolt and dogging mechanism. An electrical timer is connected to the dogging mechanism by a solenoid and starts to count upon an attempt to open the door. After a predetermined time interval has run, the electrical timer releases the dogging mechanism and allows the door to open. If the electrical timer fails to release the dogging mechanism, the door will still open if pushed due to operation of the fluid throttling device, which slowly shortens under pressure, allowing the bolt to clear the keeper.In order to readily align the keeper with the bolt, the keeper is loosely mounted and guided into alignment with the bolt by a bevelled guide. Upon being latched by the bolt, the keeper is held rigidly between the guide and the bolt.

Abstract: An unlocking transmission mechanism is driven by a power transmission shaft of an electric control system to unlock an emergency exit door lock. The unlocking transmission mechanism includes a fixed base assembly, a slidable base assembly, a linear driving assembly, a transmission member and a linkage member. The transmission member is pivotally connected to the slidable base assembly, and the linkage member is pivotally connected to the transmission member. When the linear driving assembly is driven by the power transmission shaft to drive the slidable base assembly to move along a linear sliding stroke in an unlock-driving direction, the transmission member and the linkage member are sequentially driven to drive a manual-operated press bar assembly to unlock the emergency exit door lock. In addition, a multi-selective kit for the unlocking transmission mechanism is also provided.
