Abstract: Guiding people toward an exit of a facility includes sending messages to a plurality of sounder devices, each message addressed to a corresponding one of the sounder devices and including a payload that specifies one or more timing parameters unique to the corresponding sounder device, the one or more timing parameters specifying when an audible alarm is to be emitted by the corresponding sounder device. A broadcast alarm message is sent to all sounder devices. In response to receiving the broadcast alarm message, each of the sounder devices emit an audible alarm in accordance with the one or more timing parameters unique to the corresponding sounder device relative to a time of reception of the broadcast alarm message to produce the perceivable sequential audible sweep from the sounder devices toward the exit of the facility.

Abstract: Systems and methods of power-safe control panel installation are provided. Some systems can include a control panel that includes a programmable processor and executable control software stored on a non-transitory computer readable medium, wherein the programmable processor and the executable control software can transmit a signal to selectively remove power from at least one portion of the control panel.
