Claim Text:
1. A method for activating a stimulus on a notification device, the method comprising: encoding a direct instruction to activate the stimulus in a non-primary voltage dropout pulse of a single synchronization protocol, wherein the non-primary voltage dropout pulse is separate from a primary voltage dropout pulse of the single synchronization protocol in which a direct command to synchronize activation of the stimulus with other stimuli is encoded; and sending the single synchronization protocol, including the primary voltage dropout pulse and the non-primary voltage dropout pulse, directly from an alarm control panel over a single two-wire circuit to which a fire notification device and a mass notification device are independently coupled, wherein the fire notification device includes a first decoder for decoding the single synchronization protocol and the mass notification device includes a second decoder, independent and separate from the first decoder, for decoding the single synchronization protocol, wherein the notification device is the fire notification device or the mass notification device, and wherein the fire notification device is housed within a first housing, and the mass notification device is housed within a second housing that is physically detached from the first housing when the fire notification device and the mass notification device are connected to the alarm control panel.
