Systems and methods for synchronizing wireless sensor devices connected to a control panel device via multiple access point devices

A method comprising:

• a sensor device periodically exiting a sleep mode to receive a wireless beacon that includes a starting point of a temporal pattern alarm cadence and a timestamp of an access point device from the access point device;
• the sensor device using the timestamp of the access point device to synchronize with the access point device;
• and
• the sensor device using the timestamp of the access point device and the starting point of the temporal pattern alarm cadence to calculate a current phase of the temporal pattern alarm cadence by calculating a gap between the starting point of the temporal pattern alarm cadence and a first real time of a local clock of the sensor device.

A system comprising:

• a control panel device;
• an access point device;
• and
• a sensor device,
• wherein the control panel device periodically transmits a time signal to the access point device,
• wherein the access point device periodically receives the time signal from the control panel device and uses the time signal to synchronize with the control panel device,
• wherein the access point device periodically transmits a wireless beacon that includes a starting point of a temporal pattern alarm cadence and a timestamp of the access point device to the sensor device,
• wherein the sensor device periodically exits a sleep mode to receive the wireless beacon from the access point device and uses the timestamp to synchronize with the access point device, and
• wherein the sensor device uses the timestamp of the access point device and the starting point of the temporal pattern alarm cadence to calculate a current phase of the temporal pattern alarm cadence by calculating a gap between the starting point of the temporal pattern alarm cadence and a real time of a local clock of the sensor device.
