An endpoint device may be operable to transmit and receive data wirelessly via a medium to which access is time-division multiplexed into a plurality of repeating windows. A first window of the plurality of repeating windows may be time-division multiplexed into a plurality of timeslots utilized for transmitting beacon signals. A second window of the plurality of repeating windows may be time-division multiplexed into a plurality of timeslots utilized for transmitting alarm signals. The endpoint may be assigned one of the first timeslots and, when an alarm condition is present, select one of the second timeslots for transmitting an alarm signal based on the assigned first timeslot, and based on a hash function. The endpoint may then transmit an alarm signal during the second timeslot. The endpoint may be operable to synchronize its local clock by listening to beacons transmitted by other endpoints.
