ABSTRACT:
An auto synchronous output module for use at a plurality of zones in a fire alarm and detection system consisting of a power source and output devices selectively coupled to the power source so as to provide audible and visual signals, and a microprocessor within the module for coupling to a data line so as to enable transmission of data signals to and from a loop controller. Moreover, there is within the processor, responsive to an activate command from the loop controller for applying the power source to the output devices responsive to an alarm condition. In addition, within the processor, responsive to a synchronize command, sent subsequently to the activate command, from the loop controller, for applying power to the output devices in synchronism with application of other power sources to output devices at other respective modules.
