Abstract: In accordance with the embodiments of the present invention, an alarm system is provided. The alarm system includes a system controller coupled to at least one initiation device. At least one textual notification device such as for example a signboard is coupled to the system controller. In one embodiment, the textual notification device is a multi-line signboard having an alarm input and a secondary input. The textual notification device is supervised, controlled, and powered integrally with the system controller. In an additional embodiment, an audible generator can be provided that provides an audible message in conjunction with the visual message on the textual notification devices.

Abstract: A visual messaging system and device can employ high efficiency LEDs and current driven versus voltage driven circuits to reduce power consumption and enable the device to be powered from IEEE 802.3af (Power over Ethernet (PoE)) standard based power sources. The device can be powered from a local area network (LAN) connection using PoE, and does not require a separate AC power supply. The present invention also uses a 1× yellow algorithm to create the yellow color with one half the instantaneous current of previous circuits. The device can incorporate multiple message inputs for receiving and displaying messages having different priorities, allowing higher priority messages to override lower priority messages.
