Abstract
A communication system (200) includes a portable radio (100) which has environmental detection capabilities. The radio (100) upon detecting the presence of an environmental condition such as smoke above a predetermined threshold, transmits an information signal to a communication station (202). Once the signal is received by communication station (202), it is decoded and a message is annunciated. The communication station (202) can transmit a message to radio (100) in response to the information signal. Optionally, before radio (100) transmits an information signal to the communication station (202), it first determines if the environmental condition (e.g. smoke) has been detected for a predetermined period of time.
