摘要： An exit device that includes a locking mechanism for locking and unlocking a door, the locking mechanism having a latch bolt, and a link connected to the latch bolt, movement of the link between locked and unlocked positions causes movement of the latch bolt between an extended state and a retracted state to lock and unlock the door, and a motor operably connected to the link. A method of operating the exit device includes operating the motor to move the link in a first direction toward the unlocked position, the motor being operated until the link reaches a hard stop position; thereafter determining a soft stop position based on the hard stop position; and thereafter selectively using the motor to move the link in the first direction toward the unlocked position, the motor being operated only until the link reaches the soft stop position.

摘要： An electromagnetic doorholder for retaining a door in an open position by magnetic interaction with an armature secured to the door. The doorholder includes a core having a face confronting the armature and a coil of wire surrounding the core. A cup having an inside diameter somewhat greater than the coil outside diameter receives the coil, the core extending from the face to the cup bottom. A power control circuit including a resistor circuit controls electrical power supplied to the coil, the power control circuit being mounted on a circuit board situated between the coil rear surface and the cup bottom. The resistor circuit being situated in sufficiently close proximity to the cup bottom for transfer of heat from the resistor circuit to the cup. The power control circuit also includes a low resistance circuit coupled to the resistor circuit, the low resistance circuit including a fusible link, the fusible link being selected to carry current when the power input terminals are coupled to a lower voltage power source and to stop carrying current when the power input terminals are coupled to a higher voltage power source.

摘要： The assembly, in a first embodiment thereof, comprises an annular cam retainer which rotatably journalled on the mortise cylinder of an exit alarm unit, and has a limb disposed for movement by the tailpiece of the mortise cylinder for engagement with a bearing surface on the rotary, switch cam of the assembly. The cam retainer retains the rotary, switch cam in an alarm-silenced position while the key may be rotated in its key cylinder to a disengageable position and removed. The modification kit comprises a cam retainer (i.e., an unthreaded annulus, in one embodiment) required for modifying a key-operated, exit alarm, switch cam assembly to enable removal of the key with the alarm in a silenced position as aforesaid. The modification method sets forth the precedural steps in retrofitting a switch cam assembly with such a modification kit.

摘要： A switching assembly for use with an exit alarm lock. The switching assembly uses two reed switches which must both be closed for the alarm horn to sound. An arm/disarm switch is operated by a magnet on a pivotable switch link which is operated by a link boss on rotatable deadbolt cams which are operated by the key cylinders. An alarm switch is operated by a magnet in the deadbolt.
