A car alarm is provided for a vehicle. The alarm has a warning system having a sleep alert device with a touch sensor and a siren. When the system is switched ON the touch sensor must be touched within a first set time period. Otherwise the siren will be energised for a second set time period or until the touch sensor is touched. In a preferred embodiment, the warning system also has a anti-theft device which is put in operation by turning the ignition switch to the OFF position. A programmed controller means is employed for controlling functions of the sleep alert device and the anti-theft device. |
