A vehicle security system including a remote control communicating with the system via an RF link for remotely arming and/or disarming the system. Modes of system operation include an armed mode in which sensor outputs are monitored for intrusion indicating conditions and an RF receiver is monitored for remote commands, an alarm mode in which a siren is sounded in response to a detection of an intrusion indicating condition during the armed mode, a disarmed mode in which sensor monitoring for intrusion conditions is disabled, a programming mode in which features of the system are programmable, a valet mode in which only selected sensor outputs are monitored, and a pre-arming mode following system disarming and prior to passive arming, in which the door switch is monitored. A display facilitates programming by providing an indication of the present position within the programming sequence. A customizable auxiliary feature is operable with the remote control during both the armed and disarmed modes and is disabled during the valet mode of operation. The remote control includes a combination vehicle locator/personal safety feature and a power reserving time-out feature. The remote control battery status is indicated both on the remote and on a display located in the vehicle. The vehicle security system includes a memory device for storing system status information so that, upon power up, the system resumes the mode of operation preceding the previous power interruption. The programmable features include adjustable siren chirp volume and selectable siren alarm patterns. |
