ABSTRACT:
A building-security method is implemented in a variety of embodiments. In one such embodiment, the building-security method is implemented for bidirectional, wireless communication between a control panel device and peripheral devices. Each of the devices includes a wireless communication circuit to effect wireless communications. The control panel wirelessly sends synchronization information to at least one of the peripheral devices. Power consumption is reduced for at least one of the wireless communication circuits by coordinating a communications time interval and a selected channel for communication between the control panel device and the peripheral device to effect wireless communications between the control panel and the peripheral device. The selected channel is one channel from a sequence of channels used for wireless communications between the control panel device and the peripheral devices.
