A system and method for facilitating user interactions with a life safety system that includes an event panel controller configured to trigger, in response to information received from the one or more life safety system components, an emergency event and insert the triggered emergency event into a queue of active emergency events. The event panel controller is further configured to display an event indication corresponding to the triggered emergency event in an event indicator region of an emergency event graphical user interface (GUI). The event indication is displayed in one of a plurality of event elements of the event indicator region, wherein the one of the plurality of event elements of the event indicator region displays information of the triggered emergency event. Accordingly, each of the event elements remains visible to a user of the event panel controller during its use. Additional embodiments are described herein.

A power system includes one or more notification circuits for powering notification devices, a backup power source, and a plurality of primary power supplies. The primary power supplies are configured to provide a combined current to the notification circuits. Each primary power supply regulates its output current to equal a highest output current provided by one of the primary power supplies so that each contributes approximately the same current to the load. The primary power supplies also include boost regulator circuits for boosting the voltage of the backup power supply.

Load-sharing and boost voltage for notification appliance circuits

A notification appliance circuit (NAC) includes notification devices having a high capacity rechargeable energy storage device such as a supercapacitor and a strobe circuit. The supercapacitor can provide energy to produce flashes over an extended time period without fully discharging. The notification devices can also make use of the fallback power strategy in which the strobe circuit operates with reduced intensity while the supercapacitor is being recharged.

Notification appliance circuit with energy storing notification devices

An intelligent notification appliance circuit has a controller and one or more addressable notification appliances coupled with a single pair of wires. The controller outputs integrated power, audio and control signals, and transmits the integrated signals to the one or more addressable notification appliances. Thus, the one or more addressable notification appliances are powered, operated, controlled, and monitored using the intelligent notification appliance circuit. When the intelligent notification appliance circuit is implemented in a fire and/or mass notification system, that system is able to provide integrated audio signals, power signals and control signals over a single pair of wires. The integrated audio signals may carry data indicative of live or recorded music and/or voice messages, such as: mass notification messages, general page, voice evacuation, and the like.
