A regional monitoring system in communication with a plurality of locally displaced detectors can implement a fusion of inputs from a variety of additional non-system devices. The monitoring system includes a wireless receiver or transceiver enabling the system to detect local traffic from the non-system devices, such as sensors. Information received from such non-system devices can be combined with information from system detectors to initiate activity on other networks, to energize actuators, or to activate system detectors that normally reside in a low energy inactive state.
