Locker supervision arrangement

摘要

The arrangement includes several lockers (la, 1b, 1c) arranged in a series, whereby each locker comprises a compartment module containing an electric circuit arrangement. The compartment modules (3a, 3b, 3c) are serially connected in a signal chain, and with a monitoring unit (2). At closed locker, each compartment module receives signals from the compartment module preceding in the series, and outputs signals to the compartment module following in the series, and outputs a signal to the monitoring unit, if the following locker is opened.
