ABSTRACT:
A control module usable to drive audible or audible/visible output devices in an alarm system can generate a modulated pulse sequence in accordance with a desired output function. Sequence initiating pulses can be transmitted to output devices with a predetermined, substantially constant period. Additional pulses can be coupled to the output devices, between the initiating pulses, and later in time based on functions to be carried out by the output devices. The output devices in turn demodulate the received pulse train and determine the requested function which is then implemented to provide a desired audible or visual alarm indicating output.
