Abstract

The anti-theft device is used to transmit radio signals to a fixed on mobile central control, in the case of a break-in, with the device being identified to the control. The device employs a relay (R2) which is normally in an inactive position, but which is tripped into the active alarm position by the opening of one or more series relay contacts (C1--C6). The re-setting circuit for the relay (R2) is operated by a manual push-button (P) with a timing circuit (T1) maintaining the re-setting current for a given period after the release of the push-button (P). A second timing circuit (T2) delays the alarm release for a given period after the relay (R2) operates.
