Abstract

1,215,131. Vehicle theft alarms. B. POOLE. 26 Feb., 1968 [28 Nov., 1966], No. 53183/66. Heading G4N. A relay 3 is inserted in series with part of the normal vehicle wiring which is necessarily energized on opening a door or starting the engine; normally open contacts 5 of the relay actuating an alarm 9 when that circuit is energized, hold-in contacts 4 maintaining the relay 3 energized, a switch 11 being included so as to inhibit the alarm. As shown, the relay 3 3 is inserted in the normal wiring to the courtesy light 6 controlled by door switches 7. When a secret key-operated switch 11 is opened, opening a door will close one of switches 7, energizing relay 3 and operating an alarm 9. The alarm is shunted by a thermal switch 12, contacts 13 of which periodically close so as to render the alarm intermittent. The courtesy light 6 will flash. Alternatively, the relay 3 may be included in the ignition or starter circuit. In Fig. 2 (not shown) the thermal relay 12 is replaced by an electro-magnetic relay (16) controlled by a transistorized timer (17).
