Abstract

A method of radio frequency communication for a life safety device including a controller, a hazardous condition sensor, an alarm device, and a radio frequency communications device including transmitting and receiving capability. One method includes receiving a test signal using the radio frequency communications device, lowering a voltage to the hazardous condition sensor to simulate a hazardous condition to test the hazardous condition sensor, and emitting an alarm using the alarm device if the hazardous condition sensor passes the test. Another method includes before transmitting a radio frequency signal, turning on the radio frequency communications device for a period of time, and delaying transmission if the radio frequency communications device receives a header, deadtime and startbit. Yet another method includes sending a test signal at a first transmission power level, and sending an alarm signal at a second transmission power level greater than the first transmission power level.
