ABSTRACT:
The present invention is a method and apparatus for use in a security system that includes a number of wireless transmitters, a wireless receiver in wireless communication with the wireless transmitters, and a control panel connected to the wireless receiver. The receiver receives a wireless message from a wireless transmitter and determines if the system is in the disarm mode. If in the disarm mode, then the receiver determines the product type of the wireless transmitter from the wireless message. The receiver then determines from the transmitter product type if the transmitter is essential or non-essential. The receiver discards the wireless message if the transmitter is indicated to be non-essential, and it sends the wireless message to the control panel if the transmitter is indicated to be essential. During the armed mode, all transmitted messages are considered essential and are sent by the receiver to the control panel.
