ALARM SYSTEM WITH REPEAT OF ALARM INTERRUPTED FOR PRIORITY ALARM

摘要

A selected predetermined coded alarm is provided indicative of the one of a plurality of leads on which a signal indicative of a alarm condition may appear. If a station coded alarm, the coded alarm is immediately terminated and the station coded alarm is given priority and transmitted immediately. Upon completion of the station coded alarm, the coded alarm being transmitted at the time of the receipt of the station coded alarm is transmitted with the new transmission starting at the start of its code irrespective of the status of the transmission at the time of the interruption. Appropriate delays are provided between codes and code elements. The plurality of leads are sequentially scanned, but once a transmitted code is transmitted, it is not retransmitted on a subsequent scan unless a reset signal has been provided. Each transmitted code is repeated a predetermined number of times. The specific code transmitted in response to a signal on any of the leads may be controlled by wiring options.
