Abstract: Devices, systems, and methods for filtering noise in an event device system are described herein. In some examples, one or more embodiments include an event device comprising a transceiver having an antenna, a memory and a processor to execute instructions stored in the memory to cause the transceiver to perform a long scan for noise via the antenna at a predetermined sampling duration, determine whether a noise level of the noise exceeds a threshold noise value, determine whether the noise is detected in at least one of a first channel and a second channel of the event device, determine a noise filter threshold for at least the first channel and the second channel based on whether the noise is detected in the first channel and the second channel, and apply the noise filter threshold to filter future noise.

Abstract: An apparatus is provided that includes a control panel of a security system that protects a secured geographic area, a plurality of sensors, a plurality of annunciators, a processor that wirelessly exchanges information with the sensors and the annunciators based upon a timing table defining a repeating superframe having a plurality of non-overlapping time periods including at least one response period, at least one request period, and at least one silent period, a processor of the control panel that transmits an activation message to one of the plurality of annunciators within the response period of a first of the plurality of non-overlapping time periods, and a processor of the one of the plurality of annunciators that processes the activation message and directly synchronizes an audio or visible output of the one of the plurality of annunciators to a subsequent one of the plurality of non-overlapping time periods.

Abstract: A system is provided that includes a plurality of sensors that detect threats within a secured geographic area, a control panel that monitors the plurality of sensors for activation, a primary control unit that forms a primary mesh network coupling the plurality of sensors with the control panel based upon relative link quality, wherein the primary mesh network is defined by a primary routing table, and a redundant control unit that forms a secondary mesh network coupling the plurality of sensors with the control panel based upon the relative link quality, wherein the secondary mesh network includes a respective relationship of each of the plurality of sensors defined by a secondary routing table, wherein the redundant control unit is located in a different geographic location than the primary control unit within the secured geographic area, and wherein the secondary routing table is different than the primary routing table.
