Abstract

1,048,415. Intruder alarm systems. F. A. RODRIGUES. Sept. 30, 1963 [Sept. 28, 1962], No. 36918/62. Heading G4N. An alarm system comprises a number of parallel connected detector switches 12<1> . . . 12<n> actuable by movement of for example doors or windows connected in circuit with a combination switch 15 to a number of parallel connected connectors 11<1>... 11<n>, the combination switch being shunted by a manually operable emergency switch 16 situated, for example, near a door. A portable indicator unit A having a connector 2 which may be connected to any one of the connectors 11<1>... 11<n> includes a lamp 3, a buzzer 4 with a cut-out switch 5, and a latching relay 7 reset by an arm 17. When combination switch 15 is set to one of its closed positions, movement of a door or window completes the circuit to relay 7, energizing the lamp and buzzer. In a modification according to the drawing accompanying the Complete Specification (not shown), the relay is held energized through the lamp or buzzer and a further contact on it completes a circuit to an A.C. energized horn on the outside of the building. The switches 12<1> ... 12<n> may also be actuated by a member of a machine, for example a vehicle gear lever.
