Abstract: A smoke detector system employs smoke detectors that enter a “lockout period” following receipt of an alarm signal, during which time a detector will not receive a RF alarm signal and will not transmit a RF alarm signal after a certain period of time if that detector does not detect, or no longer detects, a dangerous condition. The lockout period is of sufficient duration to prevent re-transmission of a RF alarm signal by a detector even though it may have received a RF alarm signal from another detector(s). Hence, after a short period of time, no RF alarm signals will be received or transmitted and each detector resets, unless a dangerous condition is detected.
