Abstract
An alarm panel of a security system communicates with a remote monitoring arrangement using a cellular communication protocol which deports from the conventional AMPS protocol and is less vulnerable to fraudulent activities. The modified protocol reduces transmissions from the cellular arrangement to the cell site by ignoring query signals. The cellular arrangement continues to monitor received cellular transmissions to provide an assessment of the ability to respond.
