Abstract
There is disclosed a digital dialing system operative to send a subscriber code and an alarm indication to a remote station via a communications link such as a telephone line. The digital dialer employs a memory which is preprogrammed to store a number of a central station to be dialed and which automatically transmits to that station when accessed, a code manifesting the location having the difficulty. The memory is further adapted to automatically transmit an additional signal indicative of the type of alarm condition such as a fire or a burglary which conditions are stored at predetermined locations in the memory. These memory locations are accessed by a memory address counter which is set at the end of a zone identification procedure by an alarm logic circuit. The dialer thus allows one to store a plurality of conditions indicative of different types of alarms to enable the central monitoring station to send or direct the proper equipment or authorities to the scene as the Fire Department, Police Department, and so on.
