摘要: A plurality of hazard alarm devices are in spatially diverse locations and coupled together with an input-output bus. An interconnect protocol enables non-originating alarm devices to synchronize their audible alert tone pulses with audible alert tone pulses from an originating alarm device in a local hazard alarm condition. Hence, all audible alert tone pulses start sounding substantially together with allowances for signal contention and arbitration between the spatially diverse alarm devices.
