Abstract
A lock has a body (10) holding a locking member (11) that can be locked to or released from the body (10) by, for example, operation of a key (21). The lock includes an alarm (25) that is triggered by the locking of the locking member (11). If, however, the lock is unlocked and relocked within a predetermined time interval, the alarm (25) is disarmed. In this way, the lock can remain locked but with the alarm (25) disarmed. The signals that cause the alarm (25) to arm and disarm can be produced in any convenient way.
