  • Patent number: 7999692
    Abstract: The present invention provides a non-addressable notification appliance having multiple (e.g., dual) visual alarms such as strobes for notifying individuals of different types of detected events. For example, the notification appliance of the present invention could have a first strobe for indicating a fire, and a second strobe for providing mass notification of a different emergency such as a terrorist threat or attack. In one embodiment, the visual alarms could be colored differently from one another (e.g., clear and amber). In a typical embodiment, the dual notification appliance could be one of many non-addressable dual notification appliances utilized in a single alarm system that are controlled by a system controller.
