Abstract

A vehicle security system includes a siren for sounding a siren security alarm to supplement a horn security alarm responsive to operation of the horn in a predetermined pattern, such as by a security controller. The siren may not sound the siren security alarm responsive to selective occasional operation of the horn, such as by the user. The vehicle may include a horn being electrically operable, and a horn switch permitting selective occasional operation of the horn by a user. The vehicle security system may also include the security controller for operation of the horn in the predetermined pattern to sound the horn security alarm responsive to at least one security sensor, such as for a vehicle security breach. The vehicle security system can be readily installed, or the siren can be readily interfaced to an existing security system, for example. The vehicle also typically includes an ignition switch being switchable between ON and OFF positions, and the siren may sound the siren security alarm further responsive to detecting the ignition being in the OFF position. In addition, the siren may not sound the siren security alarm further responsive to detecting the ignition being in the ON position.
