Abstract
A user friendly security apparatus and system for use in the home or small business. A logic architecture is provided which permits the monitoring of not only intrusion but also fire, special emergencies, low battery conditions or flooding utility power failure and the like. Positions to be secured with the system are monitored by small R. F. transmitters of restricted range as well as by hand held transmitters which are used for emergency conditions and the like. A transponder is provided for mounting within the home or business in the form of a console which responds to transmitted signals as well as to a silent hold-up switch fixed thereto to carry out automatic telephone dialing to a central security monitoring service. The transponder operates in an armed or idle operational mode and includes a test feature for use in the idle mode as well as a reset feature for that mode. An armed operational mode is provided for intrusion conditions and operates in conjunction with a key actuated arm switch which must be utilized in conjunction with the detection of intrusion.
