ABSTRACT:
A versatile, economical, and structurally simple annunciator for use with a fire detection system or the like is provided which requires only a single connection with the detection system, which can be configured as desired, and which allows additional annunciators to be connected thereto. The preferred annunciator is particularly suited for use with a detection system producing data signals representative of abnormal conditions such as fire, unauthorized entry, or the like. The preferred annunciator includes a plurality of light-emitting diodes arranged in a graphic representation of the protected area and a signal processor coupled with the light-emitting diodes for receiving and processing the data signals and for selectively actuating the light-emitting diodes in response thereto according to configuration data stored in memory. The data signals are preferably optical signals transmitted over a fiber optical cable.
