A latching strike assembly for a door lock has a body ( 1, 201, 301 ) adapted to be fitted to a doorjamb. A latching strike ( 4, 204, 304 ) is mounted to the body ( 1, 201, 301 ) and defines a boundary of the latch bolt recess ( 3, 203, 303 ) of the body ( 1, 201, 301 ). The latching strike ( 1, 204, 304 ) is pivotable between open and closed positions for releasing and retaining a latch bolt ( 100 ) respectively. A bi-stable detent ( 7, 207, 307 ) is displaceable between a sable locking position at which the detent ( 7, 207, 307 ) engages the latching strike ( 4, 204, 304 ) to lock the latching strike ( 4, 204, 304 ) in the closed position and a stable unlocking position at which the detent ( 7, 207, 307 ) is disengaged from the latching strike ( 4, 204, 304 ), thereby enabling the latching strike ( 4, 204, 304 ) to be deflected to the open position by the latch bolt ( 100 ). The detent ( 7, 207, 307 ) may be displaced between the locking and unlocking positions either by a single solenoid ( 314 ) or by two separate solenoids ( 14, 15, 214, 215 ).
