A vehicle alarm system (20) includes an alert transmitter (32), alert receiver (44), alert device (46), arming unit (42), alarm unit (28), and alarm device (30). The alert transmitter (32), alert receiver (44), and alert device (46) are added to the arming unit (42), alarm unit (28), and alarm device (30) of an existing vehicle alarm system to notify a vehicle owner that an alarm condition has occurred when the vehicle owner is beyond audible range of the alarm device (30). An arming unit power source (52) and arming unit controls (54,56) are used to power and control the alert receiver (44) and alert device (46), and the arming unit (42) is coupled with an alert housing (50) to provide a unitary remote assembly (24). A pager unit (72) is provided in the vehicle passenger compartment and transmits a pager signal to the alarm unit (28B). When used with the pager unit (72), the alert receiver (44) is replaced with a transceiver (74) which operates to send an acknowledgment signal (80) back to the pager unit (72) to deactivate a pager indicator light (76). The alert transmitter (32B) is operable to send an encoded wireless signal (40B) to the alert transceiver (74) to inform the vehicle owner of the nature of the alarm condition that has occurred.
