A vehicle alarm system includes an alarm transmitter and control unit which has a paging alert circuit for transmitting an alert signal indicative of an alarm condition to a radio paging receiver. The system also includes an absence pocket associated with the control bit and into which the paging receiver can be inserted. If the correct paging receiver is inserted into the absence pocket, an address detector disarms the alarm system. If the paging receiver is removed from the absence pocket, the alarm system is armed. The absence pocket may also be arranged to recharge the paging receiver's battery when the receiver is in the pocket. <IMAGE>
