A mass notification system including one or more alarms for notification of two or more emergency classes. Each alarm can include a lens, a strobe for illuminating the lens with a first light color during activation of the strobe, and a light source such as a light emitting diode for illuminating the lens with a second light color different from the first light color during activation of the light source. During activation of the lens with the light source, the lens appears to be the color emitted by the light source. The alarm can be configured to notify occupants of a first emergency class by activating only the strobe and to notify occupants of a second emergency class by activating both the strobe and the light source. An alarm configured to provide notification of two or more emergency classes can thus use a single lens and a single strobe.

Mass notification alarm and system with programmable color output

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.

Intelligent notification appliance circuit and system

A system for isolating faults in emergency systems, the system including first and second power lines, and one or more zones. Each zone has first and second zone line isolators, the first zone line isolator is connected between the first power line and the respective zone, and the second line isolator is connected between the second power line and the respective zone. Each first line isolator is configured to disconnect the zone from the first power line upon occurrence of a short circuit in the zone. Each second line isolator is configured to connect power from the second power line upon occurrence of an open circuit in the zone.
