#$%^&*AU2016277658A120170810.pdf#####ABSTRACT A system including a control panel of a security system, a memory of the security system having a reference frequency hopping pattern and a reference frequency offset saved therein, a plurality of wireless threat sensors that communicate with the control panel using the reference frequency hopping pattern and a fixed frequency offset for each frequency and each hop of the reference frequency hop pattern where the fixed frequency offset is an integer multiple of the reference frequency offset, a processor of the security system that detects any nearby security systems that use the reference frequency hopping sequence and that determines the integer multiple of the reference frequency offset used by each of the nearby security systems and a processor that sets the fixed frequency offset used by the plurality of sensors at a selected integer multiple of the reference frequency offset that is not used by any nearby security system. - 13 -Attorney Docket No. H0049436 8364/118002UTI Application No. 15/008,088 Replacement Drawings 2/2 100 10811 114 102 10 4 116n 118 112 FI G. 2
