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, andwherein 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.

20. A method for controlling a first operation comprising 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, wherein the encoding comprises; providing a secondary voltage dropout pulse of the single synchronization protocol to control a second operation; and providing the non-primary voltage dropout pulse as a tertiary voltage dropout pulse of the single synchronization protocol to indicate whether the stimulus is associated with the fire notification device or with the mass notification device, wherein a presence or an absence of the tertiary voltage dropout pulse indicates whether the stimulus is associated with the fire notification device or with the mass notification device, and wherein a time delay between the primary voltage dropout pulse and the tertiary voltage dropout pulse indicates a type of the stimulus; 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.
