Central monitor for home security system
First Claim
1. In a security alarm system having a plurality of sensors for one or more of fire, smoke intrusion, appliance operation and the like, a central monitor for monitoring and preceptibly indicating the status of each of said sensors, individual means for transmitting information from each of said sensors to means associated with said central monitor for receiving and processing such information to indicate perceptibly by said monitor the status of respective sensor causing transmission of such information, individual memory means associated with each respective transmitter means and with said receiver means for storing information which enables said monitor to recognize information transmitted by a transmitter means of said security alarm system as actuated by corresponding sensor and thereby identify the status of such sensor, the improvement comprising a programmable electronic memory having sufficient bits of memory to accommodate the predetermined indentification information to be stored for said individual memory means for each of said transmitter means and said receiver means, electronic means for loading information data into said programmable electronic memory of each said transmitter means and into said programmable electronic memory associated with said receiver means, each transmitter means having electrical coupling means for electrically connecting said transmitter to said electronic means for loading information data, said transmitter means being separable from said electronic means for loading information data after completion of loading the desired identification information data into said electronic memory to preclude altering the information data stored in said memory of each said transmitter means, said central monitor having a programmable miccroprocessor which is adapted to access said programmable electronic memory of said receiver means upon receiving transmitted information from a respective transmitter means to enable said microprocessor to process the received information and provide the corresponding perceptible indication via said monitor.

Abstract
A security alarm system has a plurality of sensors for fire, smoke, intrusion and appliance operation. A central monitor is provided for monitoring and perceptibly indicating the status of each of the sensors. To provide for communication between the sensors and the central monitoring system, transmitters are located on the sensors and a receiver is provided on the central monitor. When one of the sensors establishes an alarm condition, its transmitter is actuated to transmit information indicating the type of alarm. A portable keyboard loads information data into an electronic memory of each of the transmitters and into the electronic memory associated with the receiver. The keyboard is separable from each memory to preclude altering of the information stored in the electronic memory of the respective transmitter. The receiver identifies data transmitted from a particular transmitter by accessing its memory which is loaded with the data from the keyboard, and obtaining a match of the data transmitted to the data stored to identify the sensor. The central monitor then indicates the appropriate alarm based on the identified transmitter of a particular sensor.
