Abstract
A status detector and communication unit (20) for a padlock (10) having a body (11) and a shackle (12) at least one end (14) of which can be latched to and released from the body. The status detector and communication unit includes a casing (21) adapted to be securely retrofitted to the padlock so as to form a compact assembly without obscuring an operating mechanism (17) of the padlock, and a battery powered circuit (22) contained within the casing for co-operating with the shackle of the padlock for transmitting a signal indicative of a status of the shackle to a remote monitoring unit (93). The invention allows remote monitoring of a conventional padlock with little or no modification of the padlock.
